Making solar for flats possible at scale

Traditional solar systems are difficult and expensive to scale across apartment buildings. SolShare enables one rooftop solar PV system and community battery to power multiple flats, without installing individual equipment inside each home.

Designed for both new developments and retrofit projects, SolShare helps housing providers improve SAP and EPC performance, reduce residents’ energy bills and decarbonise housing portfolios at scale.

Share rooftop solar across multiple flats

Connect one rooftop solar PV system to multiple apartments, removing the complexity of individual solar installations.

Share solar and battery energy

SolShare intelligently distributes solar PV and stored battery energy between flats, helping residents use more clean energy generated on-site.

Share the power

Instead of every flat installing its own panels, your building shares a single rooftop solar system.

 

See how SolShare works

Divide it fairly

SolShare uses a dynamic sharing algorithm to decide where and when to distribute the energy, and makes sure all of the residents get their fair share.

The best part: no one needs to manage it, each apartment's share is automatically balanced across the month.

Cut bills by up to 40% with intelligent sharing

SolShare dynamically distributes solar energy where it’s needed most, maximising self-consumption and minimising grid exports. Residents get fair access to free power, building long-term resilience against price spikes, while ther social landlord secures superior ROI.

Community batteries for social housing

Store excess rooftop solar energy during the day and share it with residents when they need it most.

SolShare integrates seamlessly with community battery systems, enabling multiple flats to benefit from stored solar energy.

Benefits

  • Increase solar self-consumption

  • Reduce residents' electricity bills

  • No batteries inside flats

  • Future-ready energy infrastructure

Frequently asked questions

Find quick answers about SolShare, the world’s first technology for sharing rooftop solar in UK flats. 
Read more FAQs
Can solar panels be installed on blocks of flats?
Yes. Solar can be installed on apartment buildings using shared solar technology. SolShare enables one rooftop solar PV system to supply multiple flats, allowing residents to benefit from renewable energy without requiring individual solar systems for each home.
How can shared solar improve EPC ratings in social housing flats?
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 for flats work in social housing?

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 social housing?

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.

Can solar and battery projects be funded through government programmes?

Yes. SolShare qualifies for major UK social housing decarbonisation programmes, including the Warm Homes Plan, Local Power Plan, ORP and Social Housing Net Zero Heat Fund.

Can solar be combined with other retrofit measures?
Yes. Solar PV and community batteries can form part of a whole-house retrofit approach alongside measures such as insulation, heating upgrades and energy efficiency improvements.
Does installing solar PV on blocks of flats require access to residents’ homes?
No. SolShare does not require solar panels, batteries or other hardware to be installed inside individual flats.

This reduces resident disruption, minimises access requirements and simplifies delivery across occupied buildings.
Do residents have to join a specific electricity retailer when installing shared solar on blocks of flats?

No. Residents maintain freedom of choice and can stay with any UK energy supplier. They also keep all market protections and benefits provided to vulnerable electricity customers.
