If your solar panels produce more electricity than your home uses during the day, you have several options: sell it back to the grid, store it in batteries, heat your water, charge an electric vehicle, or join a virtual power plant program. Battery Storage Economics Have Dramatically Improved: With LiFePO4 battery systems now costing $1,000-$1,300 per kWh and offering 6,000-8,000 cycle lifespans, residential energy storage provides 6-12% annual returns while delivering backup power security during outages. Net Metering Policies Are. Excess solar energy is the electricity your solar panels produce but that isn't immediately used by your household or business. This happens when: The sun is shining at peak levels, usually midday, causing your panels to generate maximum power. The amount of power produced depends on several factors like climate, sunlight exposure, solar panel efficiency, the tilt angle of the panels, the size of the system, and others factors. In 2025, net generation of wind and solar together accounted for 760,000 gigawatthours (GWh) of electricity, 88,000 GWh more.
