Assess Site and Gather Materials
Begin by confirming roof orientation, shade, and structural integrity; a south‑facing, unobstructed roof yields the best output. Purchase a compatible panel kit, mounting rails, inverter, wiring, connectors, and safety gear.

Install Mounting System
Secure the rails to the roof using flashing and lag bolts, sealing each penetration with waterproof tape to prevent leaks. Align the rails according to the panel layout, ensuring a slight tilt for optimal sun exposure.
Mount Panels and Connect Wiring
Clip the solar modules onto the rails, tightening clamps evenly. Route the DC cables from the panels to a junction box, using MC4 connectors and UV‑rated conduit for protection.
Set Up Inverter and Electrical Connections
Mount the inverter on a ventilated wall near the main service panel. Connect the DC string from the junction box to the inverter, then run the AC output to the breaker box, installing a dedicated circuit breaker and following local code requirements.
Testing, Inspection, and Commissioning
Turn on the system, verify voltage and current readings, and ensure the inverter displays normal operation. Schedule a professional electrical inspection; once approved, activate net‑metering if available and monitor performance via the inverter's app.
Maintenance Tips
Clean panels quarterly, check for loose bolts, and inspect wiring for wear. Most systems require minimal upkeep beyond annual visual checks.
