Why Solar Panel Maintenance Matters in Chennai
Chennai's combination of coastal dust, humidity, bird activity, and occasional sand storms from the western plains means solar panels here can lose 15–25% efficiency if not properly maintained. A clean, well-maintained system can outperform a neglected one by thousands of rupees annually.
Monthly Maintenance Checklist
- Visual inspection of panels for dust, bird droppings, or debris
- Check inverter display for any error codes or alerts
- Verify that the generation readings match expected output
- Ensure mounting structure bolts are tight (every 3 months)
How to Clean Solar Panels
- 1Clean early morning or evening — never during peak heat
- 2Use soft cloth or sponge with plain water (no detergents)
- 3Rinse with low-pressure water
- 4Wipe dry with a microfibre cloth to avoid water marks
- 5Never use abrasive materials that scratch the anti-reflective coating
Never clean panels with high-pressure jet sprays — this can damage the junction boxes and void your warranty. Use a gentle flow only.
