We’ve created the SolShare, the world’s only hardware for connecting rooftop solar to apartments.
We believe everyone should have the power to reduce their electricity bill and carbon footprint. With the SolShare, that’s possible.
For too long rooftop solar has been reserved for people that live in their own detached house, leaving those in apartment buildings missing out.
The SolShare is the world’s only hardware
that can connect multiple apartments to a
shared rooftop solar system.
This proven technology enables a
single rooftop solar system to be optimally
shared by everyone in the building.
Achieve your sustainability goals while reducing the energy bills for each resident with a SolShare - The simple and affordable solution to apartment solar.

About the SolShare
Optimised Solar Delivery to the Apartments
The SolShare monitors the energy demand of every apartment in the building and automatically delivers the solar energy to where it’s going to be used.
By delivering the solar to the apartments that are using energy at that specific moment in time, the solar energy is consumed within the building rather than being exported to the grid.
The optimised solar delivery results in the highest possible savings and biggest carbon reduction for every apartment in the building. The SolShare also makes sure everything is fair, by making sure that the same quantity of solar is delivered to every apartment over the course of each month.
Simplicity in the Solution
The beauty of the SolShare is that it’s simple.
The SolShare is installed alongside traditional electricity metering infrastructure at the apartment building’s main switchboard. Apartment access is not required and residents can still choose whichever retailer they like for their grid energy. There’s no requirement for residents to sign up to anything or trade solar via blockchain or anything complicated like that.
Put simply, the residents won’t even notice that a SolShare system’s been installed – apart from when they see their significantly reduced electricity bill!
It’s this simplicity that has made the SolShare the go-to choice for Social Housing Providers and Property Developers.
Achieve your Sustainability Goals
For too long, the only solution to apartment solar was to connect it to the landlord supply. This often results in the solar being wasted, as the excess can’t be used by the apartments and is simply exported to the grid.
The SolShare provides you with the opportunity to connect every apartment in the building as well as the landlord supply to a shared rooftop solar system.
This is vital for achieving sustainability targets. As each apartment is connected directly to solar the entire building gains a greater sustainability rating.
Each year, a typical SolShare will
produce 35 MWh of electricity

Case studies
Chatham, Kent – New Build
The client approached us with the challenge of reaching EPC B for every flat in their development. They had exhausted all reasonable measures when they discovered the SolShare.
With the SolShare they were able to specify the precise kWp associated to each flat. This fidelity enabled them
to add exactly the right number of SAP points to each flat to achieve the goal of EPC Bs throughout the building.
The client was extremely happy to be able to achieve the EPC B in a simple, low cost method.
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%.
Whetstone, London – New Build
The client’s objective was to develop a building of net-zero flats. To achieve this, solar had to be connected to each flat and funnel any excess energy produced to a heat battery contained within each flat. Space constraints meant that installing 20 individual inverters for each flat was not an option.
The developer learnt about the SolShare and was delighted to learn that just two inverters and two SolShares were needed to connect all 20 flats to solar. All the equipment was easily housed inside a small plant room on the ground floor.
The SolShare solution increased the SAP scores and achieved certified net-zero status for every flat in the building.
Norwood, London – Retrofit
The client wanted to provide solar energy to each of the 6 flats in the building. However, the limited roof space made multiple individual systems infeasible.
The SolShare provided a solution to connect all 6 flats to solar PV while still providing a decent bill saving for each resident.
Ashfield, New South Wales
The strata corporation of this classic red brick apartment building in Sydney’s inner west retrofitted rooftop solar to reduce the electricity bills for all residents and the common light and power.

As seen in
“One Step Off The Grid has followed Allume’s progress with its SolShare technology with great interest, as it works to break through the solar ceiling for those consumers traditionally “locked out” of the rooftop solar market, including renters and apartment dwellers.”
- One Step Off The Grid
“As the world’s first behind-the-meter solar sharing technology, SolShare is used to knocking it out of the ballpark, but becoming the first Power Division Control System (PDCS) to be UL certified is a game-changer.”
- PV magazine
“The SolShare is the most efficient system to maximise the use of energygenerated at any given time. It achieves this by supplying energy to where it is needed most, instead of sending it back to the grid.”
- Utility magazine
“Previously we have been limited in the use of solar in multi-occupant buildings such as apartments or offices due to limited roof space, but Allume’s technology allows everyone to use affordable solar power,” said Stuart Penklis, Mirvac's head of residential.
- Australian Financial Review
“People in the past have looked at the tech and tried to crack this and not really been able to,” Mr Lucas said. “We are particularly interested in Allume’s solution. It’s a segment of our customer base that hasn’t traditionally been able to access solar because of the way it’s metered and shared and this goes a long way to solving that physical element."
- The Australian
“Allume sees a huge opportunity for improvement in Australia’s low-income housing space, with state and territory government as well as not-for-profits providing homes for roughly 800,000 people around the country. Putting solar on all of these dwellings – detached, semi-detached and multi-unit – would not only level the playing field for people already at a disadvantage to home owners, but would add another 1,600MW to Australia’s rooftop solar capacity."
