Rooftop solar PV systems are a long-term investment, and their performance depends heavily on proper operations and maintenance (O&M). In India, where dust, heat, and monsoon conditions affect panels, structured O&M ensures reliability and maximum returns.
The first best practice is regular cleaning of modules. Dust and bird droppings can reduce efficiency by 5–15%. Using soft water and non-abrasive tools prevents damage while restoring optimal output.
Routine visual inspections are equally important. Cracks, hotspots, or loose connections can escalate into major faults if ignored. Trained technicians should check modules, junction boxes, and mounting structures periodically.
Monitoring systems are essential. A remote monitoring platform allows real-time tracking of energy generation and alerts operators to deviations, enabling proactive maintenance.
Inverters, the heart of the system, require special care. Checking ventilation, firmware updates, and protection settings ensures their long service life.
Safety should never be overlooked. Proper grounding, surge protection, and periodic electrical audits reduce fire and shock hazards.
Another best practice is performance benchmarking. Comparing actual generation against expected output under local irradiance helps identify hidden inefficiencies.
Documentation matters too. Maintaining logs of cleaning schedules, inspections, and service reports provides traceability and ensures warranty compliance.
With India’s push toward rooftop solar adoption, following these practices will not only maximize generation but also extend system lifespan.
For homeowners and businesses, robust O&M is the difference between just installing solar panels and truly unlocking their long-term value.
