About the installation.
This home now makes its own electricity and keeps some for the evening.
We fitted:
- 14 solar panels, giving a 7.14kWp array
- a Sigenergy SigenStor battery with 2 battery modules, storing 16kWh
- a 12kW SigenStor energy controller, which runs the panels and the battery from one unit
- a home EV charger
The battery sits on the side wall. It stores solar power from the day so the home can use it after dark.
