What effect could a battery have on my bill?
A battery will generally help to reduce your electricity bill. The electricity your solar panels generate using the power of the sun is free and the battery will make the most of the way you use this free electricity. Changing the way you use electricity is another way to maximise the savings on your bill. If you can shift most of your electricity consumption into daylight hours, this will help to make the most of your electricity and potential savings.
