A rooftop solar system needs very little upkeep — but skipping the basics quietly costs output.
What to check
- Dust and bird droppings — clean every 2–4 weeks in dry seasons.
- Cables and connectors — inspect annually before monsoon.
- Inverter display/app — watch for output drops versus last year.
"Dust alone can cut output by 15–25% before you'd notice anything visually wrong."

| Panel cleaning | Monthly |
| Full inspection | Annual |
A dusty or shaded panel behaves a lot like a poorly designed one — see how shading affects output. Maintenance plans are often bundled into Complete Package proposals.
