Roof Top Solar Installation
The solar panel array is neatly mounted on the roof in full sunlight.
The panels are mounted to a metal roof using UniRac railing and clamps. The racking system keeps the panels up away from the roof to allow for air flow and cabling. It's important to allow for air flow to keep the panels cool and operating efficiently.
Exterior PV Connections
The system wiring is protected from the elements with the conduit
The cables are protected and secured to the building to keep them safe from animals and the elements. The placement also allows for easy access to check connections should something go wrong with the system.
The PV is run into the combiner box inside the building. The electronics are kept dry and
It's extremely important for the lifespan of the charge controller, inverter, and batteries to allow the interior components to stay as cool as possible.
The system uses a combiner box, disconnect switch, SMA charge controller, Aims power inverter, and an HYE charge controller.
Combiner Box Wiring
The PV array runs into a PV combiner box located inside the building.
The bus bar combiner box combines multiple wires in one place
Charge Controller Wiring
The SMA Charge Controller features two breakers and can handle battery systems of up to 150 amps.

Trojan Battery Bank
The sixteen Trojan batteries are contained in a box built below the electronics. They are spaced with enough room for air to pass around all 4 sides of the battery.
