SolShare empowers you to fine-tune the energy efficiency rating of each flat through precise kWp allocation. This translates to a customised SAP boost of 5-15 points.

Maximise your ROI by directing the exact amount of kWp to each flat.
No sign ups, no complexity.
SolCentre provides you with all the energy data you need: total energy demand, and solar delivered, consumed & exported. On a per flat basis.
Pair SolShare with batteries, PV diverters, and smart devices to achieve your sustainability goals.
Suitable for private & B2R, and traditional or private wire building networks.
Improve the carbon savings (DER) and the running costs of the building.
By allocating the specific kWp associated to each flat, you can add the exact SAP points required to achieve your EPC goals. This table shows how modular house builder TopHat have specified the exact kWp to each flat to bring them all from a varying EPC C to a level EPC B.

SolShare creates a direct, behind-the-meter connection of rooftop solar PV to each flat in the building. Take a deeper dive into how it works.
Watch a short video on what residents say about the benefits that they’ve seen because of SolShare.
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.
No. Depending on your requirements, you can select just some of the flats to be connected to solar. The most common reason for this is that some of the flats have not achieved the desired EPC rating. If this is the case, you can connect just those flats to the solar to achieve your EPC goals at the lowest possible cost.
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, 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.
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.
SolShare can be installed onto an existing PV system under certain circumstances. Typically, if the system is simply connected to the Landlord meter, a SolShare can be retrofitted to this system. We are very happy to review any existing system that may be installed to confirm the compatibility with SolShare.
