The numerous benefits of solar energy are well known – lower electricity bills, reduced bill shock, and smaller carbon footprint. These benefits are especially impactful for community housing residents. The SolShare finally offers a simple, low-cost method of unlocking the benefits of solar for residents who live in flats.
Solar for Social Housing Flats
The SolShare is the world’s only hardware solution for sharing solar to flats. It’s connected to the flats via the building’s main switchboard, so there’s minimal disruption to the tenants during installation. The residents also retain the right to choose whichever energy retailer they like and aren’t required to sign up to any additional services in order to enjoy the solar energy. In fact, with a SolShare system, the only thing the residents will notice is significantly reduced electricity bills!
How it works
The SolShare is a distribution box that can direct solar energy to multiple flats behind-the-meter simultaneously. It optimises the solar delivery based on who needs the energy at any point in time, while also ensuring that every apartment receives the same amount of solar over the course of each month.

Case studies
Cardiff, Wales – Wales & West Housing
The client’s brief was to connect all 24 flats to rooftop solar PV and battery storage. The initial proposal was to connect an individual solar system with individual batteries to each flat. The space requirements for 24 inverters and 24 batteries left the attic as the only place to house the equipment. This was deemed inappropriate by the client and the project ground to a halt.
Upon discovering the SolShare, the solution was able to be dramatically simplified to two inverters, two SolShares connected to 12 flats each. The reduction in hardware enabled the equipment to be installed next to the meter room on the ground floor, green lighting the project. The simplification also reduced the project costs by 25%.

Frequently Asked Questions
Yes. The SolShare is classed as a direct connection of solar PV to flats. It therefore qualifies for SAP 10.2 PV credits – typically adding 5-15 SAP points to each flat.
Yes. The SolShare typically adds 5-15 SAP points to a flat. As each EPC band is around 10 points, each flat is highly likely to increase it’s EPC band by at least one rating.
Yes, any separately metered connection can be added to a SolShare system, including the Landlord supply.
The SolShare comes with an industry standard 10-year warranty.
Yes, batteries can be included in the system. Even better, because the SolShare is a shared system, your batteries will also be shared. This means that rather than needing to buy an expensive battery for every connected unit, you simply by a communal battery that everyone uses when they need it. This greatly increases their value for money.
Every SolShare installation is unique. Once we have gained the relevant information from you, we will introduce you to one of our certified SolShare installation partners. They will be able to talk you through what is most suitable for your building.
Typically, the SolShare is suitable for apartment buildings that have more than 6 apartments. Send us an enquiry and we will be happy to see if our technology is suitable for your apartment building.
As with all solar installations, every connected unit must have a smart electricity meter. If the apartments don’t have smart meters, don’t worry. Our certified SolShare Installation Partners will be able to guide you through upgrading. Residents can also contact their energy retailer directly and upgrade the meters in advance.
Every connected unit will receive feed-in tariff payment for any solar they don’t use.
The SolShare ensures that the same quantity of solar is delivered to each connected unit over the course of each month. It works hard to deliver each unit’s solar when they are using power and therefore when they’re going to save the most amount of money. However, if this is not possible and more solar is being delivered than can be consumed then it will be exported to the grid and your retailer will buy it off you.
No. Residents can stay with their existing retailer, or to choose to change to another one. They can also access any market protections provided for vulnerable electricity customers, if applicable.
The SolShare qualifies for numerous funding schemes, including the Social Housing Decarbonisation Fund Wave 2 and ECO4 funding. Contact us for guidance.
There are a number of factors in determining this, the main one being how much energy you use. But on average, a 40% reduction in grid energy usage can be achieved. This is increased further if batteries are included. See our cases studies for more information on price and payback.
The monitoring portal provides energy data for the entire building and is available to the system owner. This is often a stipulation for funding initiatives like the Social Housing Decarbonisation Fund Wave 2.
