Checklist
Solar O&M checklist for commercial rooftops
A practical operations checklist to keep C&I solar plants performing year-round.
Commercial solar underperforms quietly when soiling, loose terminations, or inverter faults go unnoticed. A disciplined O&M rhythm protects yield and warranty compliance.
Monthly: visual inspection, string current spot-checks, inverter alarm review, vegetation/soiling notes.
Quarterly: torque checks on critical joints, thermal imaging hotspots, IV curve sampling, earthing verification.
Zigma Solar AMC teams deliver scheduled O&M with clear reporting so facility managers see production vs expectation.
