The world's first technology that connects multiple flats to a single rooftop solar PV system and community batteries
Allume's SolShare is a behind-the-meter energy-sharing technology that enables rooftop solar and community batteries to be shared safely across multiple flats, making apartment solar simpler, more efficient and scalable.
Launching SolShare 2
Built on the proven success of SolShare 1, SolShare 2 introduces greater capacity, advanced battery integration and faster commissioning for apartment solar projects.
- 30kW capacity — 50% more power
- Advanced community battery integration
- 50% faster commissioning
- 25% smaller footprint
- Dedicated 4G connectivity
- Dynamic power sharing to maximise self-consumption
- Tailorable solar allocation for every flat
- No equipment inside flats
How does SolShare work?
SolShare enables the power produced by a shared solar system to be split among several apartments, without the added complexities of multiple installations, individual inverters and wiring.
SolShare allocates the energy in a way that maximises savings to all, while ensuring every home gets their fixed allocation over the month.
Why choose SolShare?
Traditional solar systems weren't designed for apartment buildings. SolShare enables one rooftop solar PV system and community battery to safely power multiple individually metered flats, all while letting residents keep their existing electricity retailer.
✓ One rooftop solar PV system for multiple flats
✓ No equipment inside individual homes
✓ Seamless integration with batteries
✓ Tailorable solar allocation to maximise SAP & EPC increase
