Press release – 14th February 2023
Allume Energy, Wales & West Housing and the Welsh Government have today announced the first installation of Allume’s SolShare technology for the UK’s housing sector, to provide clean, affordable electricity to residential flats in Cardiff.
The project has connected 24 flats to lower cost solar energy at Odet Court, with the potential to meet 55%-75% of each flat’s electricity demand. Based on the average usage of 1800kWH – 2,400 kWh for a 1-bed flat this could equate to an electricity bill saving of around 50% (between £390 to £530) a year, per household, based on current average electricity costs in the UK of 34p/kWh. The project has been funded by the Welsh Government in association with Wales & West Housing as part of the Optimised Retrofit Programme.
SolShare is the world’s only technology for connecting multiple residential units within a single building to a single rooftop solar PV system. Until now, previous options involved installing individual solar systems into each unit – a largely unworkable solution for developers due to cost, footprint and inefficient energy utilisation. In the case of Odet Court, this would have meant installing 24 sets of panels, 24 inverters and 24 batteries.
Not only has SolShare significantly reduced the amount of hardware and footprint required, it has also saved 25% on solar equipment costs as compared to a typical solar system. Its ‘dynamic sharing’ capacity also delivers an improved solar utilisation of over 25%. Importantly, SolShare is suitable for retrofit projects as well as new builds, as it does not require any changes to the existing supply and metering infrastructure.
“Wales is leading the way with the installation of this new technology,” commented Jack Taylor, General Manager Europe, Allume Energy. “We hope it will serve as a template for governments and social housing providers in the UK to provide cost-effective energy efficiency upgrades to multi-unit residences.
“Simple and affordable solutions are available, so it’s great to see governments and housing associations embracing innovative technologies which help tackle fuel poverty and climate change.”
Climate Change Minister Julie James said: “This is an exciting first of its kind project for Wales and exactly the type of thinking we need to see within the housing sector.
“The decarbonisation of homes plays a big part in our journey towards a Net Zero Wales by 2050 and I look forward to following this innovative project as works progress.
“At a time when costs are rising, improving the energy efficiency of homes will not only help us to deal with the climate emergency but also help families through the cost of living crisis.
“It’s another important step in our journey towards a stronger, greener, fairer Wales.”
Joanna Davoile, Executive Director (Assets) at Wales & West Housing said: “At a time when many people are facing difficult choices of whether to heat their homes or feed themselves and their families, it is only right that we explore ways to make our homes more energy efficient for our residents where possible.”
“In recent years we have been trialling different methods of retrofitting older homes with energy-saving technologies but one of the main challenges has been how to fit PV panels and battery systems to our apartment homes so that everyone living in the schemes could equally benefit.
“The SolShare system seems to be a much fairer solution as the energy generated by the building can be shared equally to help our residents to keep their electricity costs down rather than going back to the grid.”
“We are excited to see how the technology used in the SolShare system will work for our residents.”
SolShare was developed by Allume Energy, headquartered in Australia. The technology has recently undergone rigorous review by Ofgem and has been accepted as an ‘innovation measure of substantial uplift’ for the ECO4 funding initiative. SolShare has also been specified in the Social Housing Decarbonisation Fund’s Wave 1 and Wave 2.1 applications by a number of local authorities and housing associations in the UK.
This innovative solar plus battery system was installed by local solar contractor Green Park Power and will annually produce 50,248 kWh of green solar energy for the direct benefit of residents. Each flat will equally share the energy produced, resulting in 2,094 kWh per unit.
About Allume Energy
Allume’s vision is a world where everyone can access clean and affordable energy from the sun. More than 2M Australians, 15M Americans, and 300M Europeans live in low and medium rise apartment buildings, with the roof space for solar but, until recently, no way of accessing energy generated from it. We didn’t think this was fair, and so we developed a world-first technology, the SolShare, which enables the sharing of solar energy from a single rooftop solar system amongst multiple dwellings within the same building.
This breaks down the technical and ownership barriers that have historically prevented apartment residents from accessing cheaper and cleaner energy from the sun.
Our customers span a range of industries including social housing providers, multi-family landlords, property developers and apartment owners.
With an established market in Australia, Allume is now rapidly growing in the UK and the US.
About Wales & West Housing
Wales & West Housing’s vision is to achieve strong, sustainable growth to make a difference to people’s lives, homes and communities.
We manage more than 12,500 high quality, affordable homes in 14 local authority areas across North, South and West Wales.
These include more than 3,000 dedicated properties for older people as well as innovative supported housing solutions for people with a range of particular needs.
The majority of our homes are for rent, allocated by local authority social housing waiting lists.
In recent years WWH has been working with a number of organisations and Welsh Government to trial different methods of retrofitting older homes with energy-saving technologies including increased internal and external insulation, air and ground source heat pumps and solar PV and battery systems.
We are a major developer building hundreds of new high-quality, affordable homes each year for rent in areas people want to live. All our new homes are built to be energy efficient.
Allume Energy’s SolShare technology is the winner of the Most Innovative Product (Hardware) at the Housing Digital Innovation Awards 2023 in Birmingham.
The SolShare technology was selected as the world’s only solution for connecting multiple flats to a single rooftop solar PV system.
Without the SolShare, solar energy for flats is technically and financially infeasible; it allows people who live in flats to finally access clean, affordable electricity.
A SolShare PV system typically adds between 5-15 SAP points to a flat for a total cost of just £2,000-£4,000 per flat. It saves an estimated 25% in installation costs as compared to a typical solar system and typically reduces the energy bills of apartment residents by 40%.
Allume Energy extends thanks to Housing Digital for creating the opportunity to celebrate the dedication and drive of everyone striving for innovation and excellence in UK housing.
With Net Zero by 2050 being the internationally agreed goal for mitigating global warming, we all have some serious work to do. A recent report from the International Energy Agency (IEA) suggests that to meet the target we need to at least double the global rate of renewable energy generation rollout through rooftop solar and many other means.
Solar energy is one of the most accessible renewable power options, and plays an important role in reducing greenhouse gas emissions. Rooftop solar panels help to reduce bills by up to 70% and each MWh of electricity generated by solar can save between 700kg and 1,100kg of CO2 being pumped into the atmosphere.
Given this global focus on meeting these targets, and the impact solar can have on them – let’s look at some of the solar incentives being offered around the world to help get as many people as possible to do their part.
Thankfully we are seeing government financial support for communities and businesses to access and install renewable energy products. When it comes to government incentives for integrating renewable energy into new builds or retrofit projects – rooftop solar is currently getting the most attention. Here are a few examples of what’s on offer.
For residents and businesses nationwide, there are solar incentives available for the installation of small-scale systems. To check eligibility and apply for solar incentives, visit the Clean Energy Regulator website and state energy department websites. In some cases, eligible home owners can receive rebates of up to 50% of the total cost in setting up their solar systems.
Australians are also able to access ‘feed-in tariffs’. These are small solar rebates of a few cents per kilowatt hour of electricity generated by your solar power set-up that you don’t use. This goes back into the grid and you receive your payment. Feed-in tariffs are driven by state policy, so you would need to check your state regulations to find out your rate.
A £4-billion budget has been allocated for four years (1 April 2022 – 2026) giving homeowners in the UK the chance to apply for grants through the ECO4 (Energy Company Obligation) scheme to install rooftop solar panels on their homes. Using this scheme, the least energy-efficient households can save up to £1,600 per year.
There are also incentives via the Smart Export Guarantee (which started in 2020) and enable participants to receive payments for selling excess energy back to the grid.
VAT reduction is another option for those in the UK, with 0% VAT for solar panel purchase and installation from 1 April 2022 – 31 March 2027.
The USA introduced federal solar tax credits in 2006. Also known as the Investment Tax Credit (ITC), they can be claimed on federal income taxes for a percentage of the cost of a solar PV system paid for by US taxpayers, provided the system installation is completed during the tax year.
Solar PV systems installed between 2022-2032 are eligible for a 30% tax credit. This will decrease to 26% for systems installed in 2033 and again to 22% for 2034 installations, with tax credits expiring in 2035, unless Congress renews it.
It is estimated that the ITC will cut the cost of installing rooftop solar for a home by 30%, or more than $7,500USD for an average system.
As the adoption of renewable energy is gaining more and more traction globally, we’re seeing incentives and rebate programs introduced and changing rabidly. As the solar rebates and solar incentive schemes change periodically, this article has been written to raise awareness of the kinds of programs and resources that are available at this point in time, and we’d recommend getting in touch with your local council or state government to find out the latest offers for your part of the world.
With apartments accounting for close to 40% of households globally, this meant until recently a large portion of the population wasn’t able to access the benefits of rooftop solar power. Thankfully this has changed with the development of new and much-needed solar tech, the SolShare.
The SolShare empowers tenants in multi-residential buildings such as apartments, flats and social housing to connect to a single rooftop system to access and share solar power. This makes it affordable and easy to install in any building.
A sharing algorithm responds to the real-time usage of each dwelling. This means the solar power is directed as needed, which maximises the usage and savings. The SolShare system is flexible, allowing pay-as-you-use through to outright ownership of the system and getting your green energy free. As well as this, in most cases residents are also able to choose their electricity retailer.
While the 2050 target is substantial, there are ways we can work together to meet it. Whether you’re a resident in a free-standing home or multi-residential building – hopefully you can now see there are options for you to choose from. Likewise, commercial developers can take advantage of the unique proposition available in the SolShare, which will make a huge difference in the long run. Contact Allume today to see how the Solshare can work in your new or existing building and the benefits you’ll receive.
With soaring energy prices and widespread environmental impacts as a result of harmful carbon emissions, many people and corporations are exploring the power and benefits of renewable energy sources. In particular, solar energy and rooftop solar.
Solar energy is one of the leading renewable power sources. It’s a driving force in supporting energy independence and sustainability and is being embraced worldwide.
According to the International Energy Agency (IEA), renewable energy installations exceeded previous records in 2021, with an additional 8% increase tipped for 2022. Of this uptick, solar is likely to account for 60% of this increase in worldwide renewable energy.
In this article, we are getting back to basics to provide a roundup of common solar questions, plus some helpful insights including:
Electricity and heat are two forms of energy that are created by the sun. We can use both in many different ways where solar energy is quite literally, sun energy.
When the sun shines onto a solar panel, the cells in the panel are activated and convert the sunlight into what is called direct current, or DC, electricity. Within the panel is a solar inverter, which then takes this electricity and converts it into alternating current, or AC, power. This power can be used to run your appliances, instead of using power from the grid.
When there is a surplus of energy created and not used by appliances in the home, in most countries, the excess is sent back to ‘the grid’. If you select for extra energy to be directed to the grid, in most instances you can receive a payment, known as a ‘feed-in tariff’. This is can vary from location to location and something that is worth checking with your energy provider.
Alternatively, the excess solar energy can also be directed to charge a solar battery for future use.
If you’re in the Northern Hemisphere, you will ideally want your solar panels to face south.
If you’re in the Southern Hemisphere, you will ideally want your solar panels to face north.
Whilst this is ideal, it’s not a deal breaker if they aren’t. If the panels can’t face these ways in your location, you need to make sure they aren’t in the line of shade throughout the day from surrounding large trees or any other obstructions.
Positioning is important to get the most out of your solar panel installation. The orientation of the roof, the pitch (the slope or angle of it) and available space for panels will all impact the panel positioning. What the tiles are made of can also make a difference.
Thankfully, many countries are supporting investment in renewable energy technology for both individuals and corporations.
It is certainly worth contacting your local council or government to find out about any available rebates or incentives to purchase and install solar panels, or other renewable energy products.
Now that we have a better idea of how rooftop solar works, which way solar panels should face and what happens with the excess energy that’s created, let’s look at some of the key benefits to having solar.
With soaring energy prices, having rooftop solar will certainly see you saving on your electricity bills, especially if you live somewhere particularly sunny. You can also integrate a battery for storing up extra energy to use on cloudier days and evenings. This will save you even more.
As long as the sun is shining, you will have ongoing access to your renewable and clean energy source.
Whether you pay for them upfront, or off in instalments, your investment in rooftop solar will be appealing to potential home buyers. The fact that solar panels provide environmental benefits and cost savings are two selling points that will certainly add appeal and profit to your sale price. In countries like the UK, solar panels also help to improve your EPC rating (Energy Performance Certificate) which can add value.
Generally, rooftop solar doesn’t need a lot of TLC. While it is said that the panels don’t need to be cleaned, it is not a bad idea to maintain them so they are performing at their peak. Blockers like leaves, dust and water can impact performance, so get a professional in if you don’t fancy getting up on the roof to do it yourself! One study revealed that dust accumulation impacted efficiency by 60%, so it is worth maintaining your investment. The only additional cost after the initial investment could be the replacement of the inverter, but that’s after 10-15 years.
Your rooftop solar can cut down on greenhouse gas emissions by hundreds of tonnes. The reduction amount will largely depend upon your location and how much power your panels can generate. But you will certainly be reducing the impact of harmful emissions by making the investment.
As mentioned earlier, in most countries any energy that you don’t use can be exported back to the electricity grid. Your electricity retailer will likely give you a feed-in tariff for each kilowatt hour (kWh) of unused energy that you export. Check with your retailer to discover the feed-in tariff rate they offer.
Depending on where you live and the amount of sunshine hitting your rooftop solar, you could be seeing payback on your investment within five years. The cost will be returned via the savings to your energy bills.
If you do your homework and invest in quality panels, they should last you in excess of 25 years. Pro tip: check the product warranty. The longer the coverage, the higher the likelihood that you’re looking at a quality product.
By teaming your panels up with a battery, you will be able to access solar power at any time of day or night. That means a particularly sunny week or two can actually give you nice clean renewable energy well after the sun is down.
Another reason to invest in a battery alongside your rooftop solar is to enable you to become energy-independent. Stored power drastically reduces your reliance on the main electricity grid, which means you can have enough energy for your personal use, even in the event of power outages.
While there is an upfront investment required for installing solar panels onto your rooftop, you will see the cost savings almost immediately in the reduction to your energy bills.
It is difficult to define the exact amount you will save. It depends on how many panels you have and where you are located in the world. The amount of sunshine you get impacts the energy produced.
On average, a 5kW system, which is generally enough to power an average home, could save you up to $2000 a year in a typically sunny location.
It does pay to research your region to get accurate reports.
All of these great benefits of having rooftop solar have, until recently, been limited to freestanding homes. However, there have been developments in technology that enable solar energy sharing in some instances using wireless power transfer (WPT). There’s also the option to return unused solar power to the grid, which is technically sharing the energy too.
That being said, the big game-changing invention enabling shared rooftop solar energy is the SolShare. This award-winning technology is a single rooftop solar system which can be shared by anyone residing in an apartment building, flats or social housing. Apartment solar panels are a new addition to the game and this tech is the first of its kind. The SolShare empowers those in multi-residential blocks to gain the benefits previously only accessible to those in free-standing homes.
The SolShare takes up limited rooftop space as a single system and has an algorithm that responds to each resident’s use. They receive solar energy as it’s required, which maximises both consumption and cost savings.
Developers, building strata and body corporates are embracing the new tech. It’s flexible in delivery with options for pay-as-you-use (per unit in multi-dwelling buildings) to owning the system outright and receiving the energy free.
Each year, a typical SolShare will reduce C02 emissions by 28 tonnes and cut down on grid electricity use by 35-40%.

With the combination of world events and the ever-increasing problem of climate change, it’s no wonder that property owners and building managers are looking for more sustainable ways to produce energy. But for a long time, solar panels were restricted to those living in free-standing houses with a roof large enough to hold them. Thanks to the SolShare from Allume Energy – all of that has changed.
This completely unique technology allows multiple flats to connect and benefit from a single solar energy system.
So yes, solar panels for flats are possible and here’s everything you need to know.
When it comes to solar panels in flats, there are a few different ways in which the energy generated can be used and how the tenants/owners can benefit.
Here’s how they compare:
The energy produced by solar panels on a shared rooftop can be used to power common areas in the building. This may include hall lighting, lifts, recreation areas, and hallways.
This is a simple solution and a great option if there’s limited roof space. There are three major downsides here:
Individual systems will be fitted to the roof and separately connected to each individual flat’s unit. Whilst this works well in some instances, space constraints, install complexity and cost make this a challenging option. It’s therefore often placed in the ‘too hard basket’ for blocks of flats with any more than 3-5 flats in the building.
With individual solar PV systems for each flat, there are also challenges around roof ownership. Which flats in the building should be given the roof space to install solar panels for their flat? And if there’s enough roof space for everyone, which flats should be connected to the solar panels that have the best solar coverage? All these issues can create a real challenge around fairness.
Shared solar power involves a single rooftop solar installation that can be shared between all the residents in the building and distributed when needed. The SolShare is a completely unique technology that allows multiple flats to benefit from solar energy.
In order to ensure the distribution of energy is fair, the SolShare ensures that a set quantity of solar energy is sent to every flat in the building and distributed as required. It also offers in-depth monitoring so each user knows exactly how much solar and grid power they’re using.
This is a simple, cost-effective solution and any flat with a meter can be connected to the SolShare. As well as private residences, the energy can also be used to power common areas. Anyone not interested in participating can simply opt-out.
Importantly, a SolShare solar PV system will reduce the electricity bills of every apartment in the building and contribute to each flat’s SAP score, typically increasing it by between 5-15 points.
Solar panels work by converting sunlight into energy. With the SolShare, each flat connected to the system can benefit from the energy produced by the solar panels which are installed on the roof or other sunny areas.
As well as enabling individual flats to access solar energy, the SolShare also ensures that a set amount of solar energy is distributed to each flat as and when they need it. This means that if some of your tenants work night shift, others work day jobs and others travel often – they will all receive their fair share of the energy when they need it, meaning they can save as much as possible when it comes to their energy bills. An added bonus is that each individual flat can choose the energy provider they’d like to go with when they need additional energy supplied by the grid.
As long as the building has a suitable roof area for the number of flats (typically under 7 floors), the SolShare can be fitted into council housing, new builds, and private blocks of flats. It can also be retrofitted into existing buildings so that everyone can benefit!
There are a huge number of benefits to installing the SolShare into your block of flats. These are some of the most significant:
This is one of the main reasons why owners and building managers decide to install the SolShare in their building. The average flat connected to our unique technology saves 40% on their grid electricity bills. The energy generated is shared out amongst the flats whenever it’s needed most, which ensures maximum savings and consumption. Whilst it’s the tenants that will directly benefit from this each month, it can go a long way to making your building even more attractive to renters and buyers alike.
Increasing the EPC rating of properties is a major objective towards the UK’s net-zero strategies. By installing a standard SolShare system, flats can gain an extra 5-15 Standard Assessment Points. This means an EPC rating can increase by an entire grade. You can find out more about the SolShare and EPC ratings here.
By producing your own renewable energy you’re doing a lot to decrease your carbon footprint. An average SolShare will reduce CO2 emissions by 5-6 tonnes a year.
Renewable energy is only going to get more popular and more demanded. If you decide to sell your property, buyers will be looking for flats that are powered by renewable energy. Having solar panels will make your building stand out.
Although they’re less common than they once were, blackouts can still happen. If you have a SolShare system that’s also connected to a battery energy storage system, your tenants may be able to keep the lights on even when the rest of the area is out. This is especially useful in emergencies.
Whether you’re a housing association, landlord, building manager or developer, there are a number of advantages to installing solar panels on your apartment building. With the industry-first technology from Allume, multiple flats in a building can benefit from and share the solar energy generated by the SolShare. There’s no need for multiple systems or to make it more expensive for those wanting to take part.
It’s a simple and affordable solution and the world’s only hardware that allows solar sharing within a single block of flats.
Contact the team at Allume to see how your flat or building can benefit from the SolShare.
If improving the energy efficiency of your properties hasn’t been front of mind, the recent explosion in energy prices and changes to energy related legislation in the UK may well be pushing you to prioritise it. We recently covered how you can improve EPC ratings with solar for flats, and touched on the EPC (Energy Performance Certificate) being the easiest way to establish the energy efficiency of a property. This provides you with a rating, where the better the rating the higher the energy efficiency and the lower the bills. Like school days, an A rating is top-notch, with a G rating being bottom of the heap and definitely needing improvement.
Energy efficiency is important for several reasons, including the well-being of the planet, the occupants of the property and how much they’re paying in bills. In this article, we’ve rounded up five ways you can increase the EPC rating of your property:
#1 Quality Insulation
#2 Upgrade The Boiler
#3 Double Glazing
#4 Solar Panels
#5 Energy Efficient Heating Sources
A quick and simple way to increase the EPC rating of your buildings is by installing or topping up the insulation. When you put 270mm of insulation (from none), you may be able to increase the EPC rating by a full grade or more.
Cavity wall insulation is another solution where you may be able to average a 5-10 point increase. There’s also floor insulation where you can prevent draughts by insulating under timber floors, between the joists.
Draft proofing is also important, with up to 20% of heat escaping from gaps around windows and doors. Just make sure the draft snakes you provide are made from materials that are BS 7386 standard.
The choice of heating systems will have a significant impact on the energy efficiency of the property. A quick way to increase your EPC rating is by replacing the boiler.
From April this year (2022), energy bills for the average UK household hiked by a whopping 54%. By upgrading the boiler, you could save your tenants up to £365 a year.
While installing a new boiler can be costly (anywhere from £500-£3000 depending on the boiler you select) the EPC rating could potentially go up by 40 points. That’s four whole grades that might take your property to the top of the class.
By getting the windows double or triple glazed, you will improve the insulation of the property right away, which will shrink the heating bills. With double glazing lasting anywhere from 20-35 years, it’s a long-term investment worth making to your properties to improve energy efficiency.
In terms of costs, you’re looking at approximately £200 per standard-sized window for double glazing. This will be roughly £2000 for an average flat that’s two to three-bedrooms.
Double glazing can also increase the EPC rating of your building by approximately 10 points, which is a full grade.
Thanks to the Solshare, the days of solar power benefits only being for homeowners of free-standing properties is a thing of the past. Energy efficiency via solar panels for flats is now possible with the SolShare – a system that creates a private infrastructure for individual flats to equally access shared solar energy.
A typical SolShare system will increase the EPC rating by as many as 5-15 SAP points and set you back between £2,000-£4,000 per flat total, for the entire solar installation. While a decent investment upfront, your tenants will experience lower energy bills immediately. Compared to the other options for positively impacting an EPC rating, the SolShare definitely gives a solid return on investment from the day it’s installed.
It is well worth looking at the heating systems installed in your property in terms of energy efficiency. Hydronic heating is incredibly efficient, with radiators being commonplace throughout the UK. You should keep in mind that your heating system will only be as efficient as the boiler you install to power it (taking us back to Suggestion #2).
If you want secondary heating sources in your building, be mindful of the running costs. Blow heaters, for instance, can end up costing more to run than central heating systems. They chew through a lot of electricity and tend to only warm up a small area of space, as well as being a potential fire hazard. If you’re looking at installing something other than hydronic heating, you may consider a wood-burning stove, as opposed to an open fireplace which will likely create greater efficiency and lower running costs.
Optimising the EPC rating of your buildings is a must-do from a legislative perspective, as well as to help you and your tenants to manage energy costs. With options available to suit all budgets and properties, now is the time to consider which solutions are best for your building. For flat owners and housing providers, the SolShare is certainly a game-changer with solar panels for flats now being available to millions. Those who live in flats can also enjoy the benefits of lower energy bills and reduced carbon emissions. If the idea of solar power appeals to you for your property or development, get in touch with us to discuss the SolShare and the best options for your project.
A huge milestone has been reached towards achieving net-zero flats in the UK. The SolShare’s ability to connect solar PV panels directly to flats is the keystone technology in the initiative.
In a world first, Allume’s SolShare has been combined with other world-leading, energy-saving technologies to create a near net-zero apartment building in London. Allume’s SolShare, alongside technologies created by MyEnergi, Sunamp, & NexGen have been combined to create a solar energy solution that more than doubles the energy bill savings and carbon reduction for every household within the apartment building, if compared to a standard solar system.
The solution achieves this by ensuring that 100% of the solar energy generated by the solar panels is used by the flats. Maximising the solar that’s consumed by the flats is vital because the more solar consumed on-site, the more money the residents will save on their energy bills.
As a comparison, a traditional solar system on a standalone home averages just 40% consumption. Increasing this to 100%, by enabling the solar energy to be stored for times when the sun isn’t shining, enables every resident to enjoy huge energy bill savings, no matter the time of day they choose to use energy.
The development, called Whetstone Green Apartments in north London, was brought together by SHA Environmental for MKM Developments and consists of an Allume SolShare solar PV system that connects rooftop solar panels to all 20 flats. Within each flat is a MyEnergi PV diverter, Sunamp Heat Battery and NexGen infrared heating system.
Kelly Lemon, MKM Director said “As a developer, we are proud to be bringing such a progressive scheme to the market. We have proactively worked with the various elements to bring the best technology to the scheme and we’re thrilled with the results.”
Whenever solar energy is being generated, the SolShare will direct it to the flats to cover their instantaneous energy demands from appliances, devices, lights etc. By doing this, each flat minimises its grid energy usage and maximises its energy bill savings. This optimised delivery is a standard feature of a SolShare solar PV system and already increases the solar consumption from 40% to 50-70%.
However, this project takes it one step further by using a PV diverter to direct any unused solar energy into a Sunamp heat battery charging it for use. The residents can then use this stored energy, in the form of hot water, at a time that suits them. This reduces the residents’ requirement for grid energy, keeping their energy bills even lower.
The solution has already gained industry acclamation, with the consortium invited to present the solution at the UK’s largest renewable energy exhibition, Solar & Storage Live to a packed audience.
If you would like to learn more about this project or the companies and technologies that make up the solution, please contact the team at Allume.
Last week, we at Allume were at the edge of our seats as we watched the U.S. House of Representatives vote yes on the Inflation Reduction Act (IRA). Signed into law by President Biden, the IRA includes a historic $370B investment in climate solutions and environmental justice with the goal of reducing US carbon pollution by 40% in 2030.
Congressmen applaud after Speaker of the House Nancy Pelosi (D-CA) signed the Inflation Reduction Act during a bill enrolment ceremony after the House passed the legislation. The legislation provides the largest federal investment in to the climate in US history
With our vision for a world in which everyone can access clean and affordable energy from the sun, we see a tremendous opportunity to extend the financial and environmental benefits of solar to more Americans than ever before.
It is important to note that, historically, federal tax incentives for residential solar largely benefited more affluent homeowners, furthering disparities in access to affordable solar for low to moderate income (LMI) households and apartment renters. With a population that is 43% LMI and apartment units in the hundreds of millions, access to affordable solar remains difficult, especially for communities that have been disproportionately burdened by climate change.
In fact, Allume created the SolShare to bridge the gap to accessible and affordable solar. The SolShare is our award-winning hardware solution that enables residents in apartments (better known in the industry as multifamily homes) to directly access and consume clean energy from rooftop solar panels. By dynamically distributing solar energy throughout a multifamily home, our technology helps lower energy bills for renters and landlords all while reducing a building’s reliance on fossil fuels. We call it our win-win-win.
We are excited about the many ways in which the IRA can expand access to rooftop solar for LMIs and apartment renters. Here are parts of this landmark legislation that we see as game-changers for accessible solar:
If you are a renter, building owner, or solar installer, please get in touch. We look forward to seeing how the team at Allume Energy can help you make the most of rooftop solar for your apartments or multifamily homes.
At the recent Future Build Expo in London, eFIXX Energy interviewed Allume’s General Manager of Europe, Jack Taylor to learn everything there is to know about the SolShare. The 5-minute, quick-fire interview, began with eFIXX Energy’s Joe Robinson asking Jack the simple question “What happens when you’ve got a block of flats and you want to share out that solar PV power between those flats?”.
Jack and Joe talk through the SolShare’s ability to solve this global problem. They even go into detail about how the SolShare monitors the energy demand of every flat connected to it and sends the solar energy to the flats that need it at any point in time. This optimisation significantly increases the onsite solar consumption within the apartment building. This directly equates to increased savings for the residents living in the flats.
As the world’s only solution to behind-the-meter sharing of solar PV, the eFIXX gang were excited to learn more about the SolShare and share the solution with their 250,000+ subscribers.
Joe Robinson said that “I think this is a really, really good product”
And eFIXX is “going to watch SolShare’s UK journey very carefully and with great interest”

With more and more people around the world driving Electric vehicles (EVs) and plug-in hybrid vehicles, governments, councils and building owners are having to find ways to implement EV chargers to accommodate them. In this drive to be more sustainable, it raises questions such as whether it’s possible to have a solar EV charger? And if it is, can you have solar power if you live in an apartment or flat? And of course, whether there are other benefits apart from the environmental impact?
These kinds of questions were recently touched on by The Guardian in their recent article on the hurdles apartment dwellers face when it comes to installing EV chargers, where our very own ‘SolShare’ was featured as a potential solution.
For many, the reason they decide to opt for an EV is that it’s better for the environment. No expensive petrol, no fumes in our neighbourhoods, fewer greenhouse gas emissions – it’s a win-win. Charging an EV with solar power makes it even more appealing.
A solar EV charger allows you to charge your vehicle with the solar panels attached to your roof and top it up with energy from the grid when necessary. Some independent chargers even have solar panels attached to them. In terms of appearance, they’re pretty similar to regular EV chargers but there are a lot of benefits to them for both the environment and the vehicle owner.
For many years it was very difficult, if not impossible, for apartment-dwellers to change their electricity system, install a solar EV charging station, or benefit from solar energy at all. Owners and companies believed these changes to be too expensive and unnecessary – but that’s changing. The SolShare is the world’s only hardware that allows multiple apartments to share a single rooftop solar system for an affordable price. Residents (and owners) get to reap the benefits this brings, including installing EV charging stations that run on solar power.
The EV charging stations can be wired in two ways:
So what happens if you have an EV but your neighbour doesn’t? They’re probably not going to be happy paying for their petrol while also using less solar than you because you’re using up all the solar power to charge your car. Thankfully the SolShare automatically registers the amount of solar energy that each apartment receives in a month and can ensure that every unit connected to the system receives the same. So even if one neighbour charges their car, and the others are only home before and after work – everyone gets the same solar benefit.
If the EV chargers are connected to the Common Light and Power, then there are some companies providing a billing service to ensure that the Owners Corporation (also known as a Strata Community or Homeowners Association) recoups the cost of charging from the EV owner on a user pays basis.
Whether they want to or not, property owners can’t deny that the world is changing. Governments are being voted in that have a clearer and greener plan for the future and people have a wider selection of EVs to choose from. As an example Ford has announced that all vehicles sold in Europe will be electric by 2030 and General Motors has said that their factories will only produce electric vehicles by 2035. The European Union recently banned the sale of vehicles that use petrol or diesel from 2035.
So this trend is only going to keep on growing.
The more common it is for people to own EVs the more normal it will be for them to expect a solar EV charger in their home or complex. Property owners who have the intention of renting and who haven’t installed a vehicle charger will be losing out on potential renters or current tenants will leave. As well as this, with rising energy costs – tenants may start looking for complexes where they’ll have access to rooftop solar to help reduce their energy bills.
For many, the worry comes when they think about how solar panels or a solar energy sharing system will change the appearance of their property. Luckily, the SolShare system is discrete and, as the Guardian describes it, ‘about the size of a computer’.
If you’re an EV driver, property owner, or council and you’re considering installing a solar-powered EV charging system then get in touch with us today. We’ll be happy to talk you through the SolShare and how this unique system can help make installing eco-friendly EV chargers easier and the added benefits it will bring.
