Why is my electric bill so high with solar panels?

You are Using Too Much Electricity Even if you are using a solar panel it does not mean that you’ll already waste energy. Using too much electricity than you need, it can drain up your solar energy storage. This will result in more electricity consumption that might increase your bills.
