What solar does
Solar PV turns daylight into electricity. Homes use this energy first, with any excess either exported or stored depending on system setup.
What a battery does
A battery stores excess generation so it can be used later, often in the evening. The goal is usually better self-consumption and reduced grid import.
What affects results
- Roof orientation and shading
- Array size and inverter setup
- Battery usable capacity and control logic
- Household demand profile (daytime vs evening use)
Checks before installation
- Roof condition and safe access
- Consumer unit and incoming supply suitability
- Appropriate panel and battery siting
- Clear documentation for design and handoff
