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.

Although solar panels can function in low-light conditions, you'll get the maximum power out of them if they get enough direct sunlight each day. What exact amount of direct sunlight do solar panels require? Your solar panels should, in theory, get four hours or more of direct sunlight each day.
Home solar battery systems have a lifespan of five to fifteen years. To match the 20 to 30 year lifespan of your solar power system, it's almost certain that you will need to replace your solar battery if you opt to install one today.
