In-roof solar PV + Sigenergy 37kWh battery, Fareham
A large in-roof solar installation with a Sigenergy battery system on a 1970s semi-detached. The customer now generates the majority of their electricity and exports surplus via the Smart Export Guarantee.
- 28-panel in-roof system
- Sigenergy SigenStor 37kWh battery
- MCS certified installation
- SEG registered — earns on surplus export
- Majority of electricity now self-generated
The system
Twenty-eight panels installed in-roof — integrated into the roof covering rather than mounted on top of it. Paired with a Sigenergy SigenStor battery at 37kWh, one of the largest residential battery systems available. The battery stores daytime solar generation for use in the evening and overnight, and can also charge on cheaper overnight electricity tariffs.
The result
The customer now generates the majority of their electricity from the roof. Surplus generation is exported to the grid via the Smart Export Guarantee, earning a payment for every unit sent back. The installation is MCS certified and fully SEG registered.
Why it matters
A 37kWh battery is large enough to store a full day of solar generation and carry a household through the evening and most of the night. Combined with in-roof panels, the system is both high-performing and clean-looking on the roof.
