Assess feasibility and budget
Start by evaluating roof orientation, shading, and structural capacity; a south‑facing roof with minimal shade yields the best output. Estimate the system size needed for your electricity usage and calculate total cost, including panels, inverters, mounting hardware, and labor.

Secure permits and choose equipment
Check local building codes and utility interconnection requirements; obtain any necessary electrical and building permits before purchasing. Select panels with appropriate efficiency, a compatible inverter (string or micro‑inverter), and mounting racks designed for your roof type.
Prepare the roof and install mounting system
Reinforce any weak rafters if needed, then attach the mounting rails to the roof studs using corrosion‑resistant bolts, ensuring a watertight seal with flashing and sealant. Verify that the rails are level and spaced according to the panel layout.
Mount panels and complete wiring
Clip the solar modules onto the rails, securing them with the supplied clamps. Connect the panels in series or parallel as dictated by the system design, then run conduit to the inverter location, typically a garage or utility room. Wire the inverter to the home's main service panel through a dedicated circuit breaker, following the electrician's code‑approved diagram.
Inspection, commissioning and grid connection
Schedule a final inspection with the local authority to confirm compliance with safety and electrical standards. Once approved, the utility will perform a net‑metering test, and the system can be energized. Monitor performance via the inverter's dashboard or a remote app to ensure optimal output.
Maintenance considerations
Clean panels periodically to remove dust or debris, and inspect mounting hardware annually for corrosion or loosened bolts. Most components carry warranties of 10‑25 years, so keep records for warranty claims.
