Can anyone help me with some information about solar energy. As I've understood it as you produce energy through the panels and can either consume it or sell it to enel,(who pay a lot less per kw than what they charge when you buy from them) can you store it in anyway and use later for example in the evening? If so what is this storage unit called? Where can you buy one? How much does it cost?

Thanks for any infomation
