Sharing rooftop solar to apartments

Allume’s SolShare is the world’s only hardware for connection multiple flats to a single rooftop PV, solving the longstanding problem of how to gain the numerous benefits of solar PV for flats.

SAP 10.2 states that solar PV must be directly connected to each flat in order for it to benefit from the solar PV SAP score uplift. SolShare qualifies as a direct connection and typically adds 5-15 SAP points to every flat.

More importantly, you are able to allocate the specific kWp that each flat receives. This means that you can allocate more kWp to flats that need to achieve a higher SAP boost to achieve a specific EPC rating. An example of this is detailed in the case study section.

A fully installed SolShare system typically costs £1,500-£3,500 per apartment. The range of this is mostly down to the system size connected, and therefore the SAP point uplift. As an indication, an investment of £2,500 is likely to achieve 10 SAP points.

In addition, SolShare solar PV also helps to reduce energy bills for residents and therefore helps alleviate fuel poverty for low-income households.

Due to the significant benefits at a relatively lower cost to other solutions; SolShare is applicable for numerous funding initiatives including SHDF and ECO4, where Ofgem have classified SolShare as an innovation measure of substantial uplift – resulting in a 45% uplift in available funding.

Allume offer free consultation on any apartment building that may be suitable for a SolShare system. This includes:

• System design and suitability
• Indicative SAP score uplift
• Indicative pricing

Once the project is underway, Allume also offer free wiring and system design advice.
