Why Does My Solar System Pull From the Grid Even

Not a simple on/off switch: Solar power systems are designed to prioritise self-consumption, meaning using the generated electricity before relying on the grid. Batteries further enhance this by storing excess solar energy for later use.

Grid energy storage

OverviewFormsRoles in the power gridEconomicsSee alsoExternal links

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in batteries, and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around the Alps in Italy, Austria, and Switzerland. The technique rapidly expanded during the 19
