Future-proof apartment developments with shared solar

As building regulations evolve, developers need scalable solutions that improve energy performance while keeping apartment solar projects simple.

SolShare connects multiple flats to a single rooftop solar and battery system, helping maximise solar self-consumption, support SAP calculations and prepare developments for the Future Homes Standard and Home Energy Model (HEM).

✓ Maximises solar value across multiple flats
✓ Simplifies solar delivery for apartment developments
✓ Creates a sustainability benefit for buyers and renters

Increase SAP scores by up to 20 points per flat

SolShare is recognised as a direct solar PV connection to flats, enabling developers to maximise SAP benefits from rooftop solar.

"We installed just 3 inverters with 3 SolShares to serve 35 properties. If it wasn’t for Allume, we couldn’t have done it, there simply wasn’t space to fit 35 inverters."

Frequently asked questions

Find quick answers about SolShare, the world’s first technology for sharing rooftop solar in UK flats. 
Read more FAQs
Can apartment buildings have solar panels?
 Yes. SolShare enables apartment developments to use rooftop solar by connecting one central solar PV system to multiple flats. Unlike traditional approaches that require individual solar systems for each apartment, SolShare allows developers to maximise limited roof space and provide solar benefits across the building. 
How can shared solar improve EPC ratings in apartment developments?
SolShare is classed as a direct connection of solar PV to flats, typically adding 5-20 SAP points to each flat. By adding up to 20 SAP points, SolShare increases a flat’s EPC band by at least one rating (e.g., Band C to B), helping landlords meet MEES standards and net-zero targets. 
How does solar work for flats and apartment buildings?

Solar for flats works by connecting a shared rooftop solar PV system to multiple apartments through a behind-the-meter energy-sharing system.

SolShare distributes solar energy between flats automatically, allowing residents to use more of the energy generated on-site while keeping their existing electricity supplier.

What are the benefits of community batteries for new build apartments?

Community batteries store excess solar energy generated during the day and make it available when residents need it most.

When combined with SolShare, community batteries help housing providers maximise solar self-consumption, reduce reliance on grid electricity and increase resident energy savings without installing batteries inside individual homes.

Do apartments need individual solar panels and inverters?

No. SolShare removes the need for individual solar systems, inverters or battery equipment inside each flat. A single rooftop solar PV and battery system can serve multiple apartments, reducing design complexity, infrastructure requirements and resident disruption.

Does solar add value to apartment developments?
 Shared solar can improve the sustainability credentials of apartment developments, helping developers meet energy requirements while providing residents with access to lower-cost renewable energy. SolShare also helps maximise the value of available roof space by allowing one solar installation to benefit multiple homes. 
How can developers meet FHS requirements for flats?

For apartment blocks, installing a separate PV system for every flat is often inefficient because roof space is limited, multiple inverters and connections increase complexity or some apartments may not have direct access to suitable roof area.

A shared solar system like Allume's SolShare allows the available roof space to serve the whole building. SolShare connects multiple flats directly to rooftop solar.

Because solar generation is connected at building level and supplied behind the meter, developers can improve energy performance without installing equipment inside each flat.

Although batteries are not currently mandated under FHS, they can be added where beneficial to increase self-consumption and support future energy management.
