This is assuming you are considering using 12 volt rv grade panels.

How many solar panels do i need to power my house. Rather than backfeeding excess solar power when it s less valuable batteries allow homeowners to store their excess power on site and feed that power into the house at night which reduces the amount of power they need to draw from the grid during the highest cost time of day.
