Unlock rooftop solar for apartments and
multi-dwelling buildings

Millions of apartment residents have the roof space for solar but, until recently, no way of accessing it.

We didn’t think this was fair, and so we developed a world-first technology, 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.

About the SolShare

Maximised Saving
The SolShare’s sharing algorithm responds to each participant’s instantaneous usage, directing the solar to where it’s needed to maximise consumption and savings.

Tailored for the user
A SolShare system can be delivered in a variety of ways, from pay as you use solar to owning the system outright and receiving solar energy for free.

Stay on market
The SolShare’s behind-the-meter approach means residents can maintain the freedom to choose their electricity retailer.

Each year, a typical SolShare will

35 MWh
produce 35 MWh of electricity

35 – 40 %
typical grid-electricity reduction of 35 – 40 %

28 tonnes
reduce CO2 emissions by 28 tonnes

Case studies

Parkside, SA

This landlord-owned apartment building has a SolShare to increase the attractiveness of the apartments in a competitive rental market.

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.
