Lifestyle

Your solar system will generate electricity all day. Your electricity consumption will sometimes be more than your system generates and sometime less. When it is less you will export electricity and potentially get a feed in tariff paid. Please estimate how much of your solar system generation will be consumed within your house vs solar electricity being exported.
