The installation has to say the least has been tricky. The Bus is not straight and the curve to the roof is not uniform. This makes lining up 18 panels down the “center” a custom fit. The Center row is raised 9″ to allow space above the roof vents so they still open. The 1″ aluminum angle iron structure is riveted to the sheet metal skin. It feels very stiff and the whole bus rock when trying to shake them.
6 panels will be wired in series for each of the nine 72V arrays. Two from the left side, two from the top and two from the right side. This should help balance the load across the nine arrays. The wires have been dropped through a 1″ conduit through the roof into my Pallet Breaker Box.
Each Line has a 15 Amp Switch and a 4 Amp glass fuse. The lines are then collected at an insulated Bus Bar on each side. Later to come will be the charger controller mounted to the side and the 8 batteries will sit atop the wheel well pallet. All pallets used on this bus are solid oak. The wheel well pallet is bolted to the chair rail on the side and bolted through the floor.
