Just get yourself a Tesla solar panel roof. A couple battery packs included, looks to connect to household current. These folks live the next road over. The installation was just winding up when I took these. The porta-john was was for the crew.
Those are very cool. Expensive though. The powerwalls (the giant battery packs on the side of the house) are nice. Looked into getting those on my house. It was very hard to justify the cost.
