Off-grid solar systems require four core components: solar panels (5-15 kW for residential), lithium iron phosphate (LiFePO₄) batteries (30-100 kWh capacity), MPPT charge controllers, and off-grid inverters, all installed per NEC Article 690 and local electrical codes.
The installation typically involves securing attachments like Stainless Steel Roof Hooks to the roof's structural rafters. Rails are then fastened to these hooks, and the solar panels are clamped onto the rails.
