Yes Steevc it’s connected to the house system. It’s a grid tied set up, so when we’re using more power than we are producing, we’re topped up with power from the grid. And when we’re producing more than we are using, it’s sent out for someone else to use. My roof really wasn’t ideal. It’s facing the wrong way, and the size/shape is awkward. So that’s why I mounted it on my shed roof instead.
