What Happens With Unused Solar Power? Net Metering Explained. Unused power from this solar electric array will be automatically exported to the electric grid, earning the homeowner a credit against future electric use on non-sunny days.
It can power a 110W television for 15 continuous hours, a 120W refrigerator for 14 hours, and a 40W CPAP machine for an essential 34 hours. Expandable solar generators with extra battery options can enable you to more than double the amount of power provided.
