What Happens to Excess Electricity From Solar Panels Off-Grid?
But what happens when your solar panels produce more electricity than your household or facility uses? Managing excess electricity is a crucial aspect of off-grid solar
Excess solar energy is all the electricity produced by your solar panels that you don't consume at that moment. So, if your solar panels generate a large amount of electricity between noon and 4 pm, when your only energy use is a fridge, everything not used by the fridge is excess solar energy.
As you might be thinking, excess solar energy is incredibly common. If your system is designed to supply a large fraction of your house's power, you're likely producing excess energy during the sunniest parts of the day.
If your system is designed to supply a large fraction of your house's power, you're likely producing excess energy during the sunniest parts of the day. Not producing enough energy is even more predictable—solar panels can't help much if you use any energy at night, so you end up drawing from the grid.
If your solar panels generate more electricity than you use, you can still benefit from it financially. However, this also depends on your location and the net metering policies in place. To further maximize the benefits of solar energy, homeowners should also consider investing in battery storage systems.
