Purchasing solar panels is not something you do on a whim. After all, you don't buy a solar energy system every day. It's a considerable investment so you want to make sure you choose the right solar system and get a return on your investement that's as high as possible.
Before you decide to get solar panels installed you need the answers yo some important questions. Questions like: what is the annual yield I can expect, how much does a solar energy system cost, how many solar panels do I need, what make and model solar panel will give me the biggest yield and what type of solar inverter do I need. And then there are the questions concerning feeding power back into the grid, whether or not to use power optimizers and of course how to claim your VAT back.
