Could you be losing out by spilling excess solar generation back to the grid? After all, if you’ve gone to the effort of generating your own electricity it’s only natural to want to get the biggest bang for your buck.
The simple maths is this: if you use your own solar electricity, you’ll save about 15p/kWh because you won’t have to buy from your supplier any more. If you export the electricity back to the grid, you only get about 5p/kWh for your electricity. And for customers installing after March 2019, you will have to shop around different suppliers to get the best possible price.
So there’s a clear financial benefit to using as much of your own generation as you can.
Fortunately, a few simple lifestyle hacks, plus some great bits of tech, could help you use your own solar to power your home and even your car as well.
