A common misconception is that solar panels don't work during monsoons. While energy generation does dip (typically by 30-40% compared to peak summer months), your panels continue producing electricity even on cloudy and rainy days. In fact, rain can actually help by naturally cleaning dust and debris from panel surfaces.
Tip 1: Pre-monsoon inspection. Before the rains arrive, have your system inspected by a qualified technician. Check all electrical connections, ensure junction boxes are properly sealed, and verify that the mounting structure is secure. Loose connections can be dangerous during heavy rains.
Tip 2: Clear drainage paths. Ensure water can flow freely off your panels and roof. Blocked gutters or accumulated debris can cause water pooling, which increases the risk of micro-cracks and reduces panel efficiency. Trim any overhanging branches that could fall during storms.
Tip 3: Monitor your inverter. Your inverter is the most sensitive component during monsoon. Ensure it's installed in a dry, well-ventilated area. Check for any moisture ingress or unusual warning lights. If your inverter is outdoors, verify that its IP rating is appropriate for heavy rain exposure.
Tip 4: Track performance data. Use your monitoring system to compare daily generation with expected values. A sudden drop in output (beyond what weather conditions explain) could indicate a fault that needs attention. SunMania's O&M programme includes real-time monitoring that automatically flags performance anomalies.
Tip 5: Schedule a post-monsoon service. After the rains end, schedule a thorough cleaning and inspection. Monsoon months often leave behind stubborn stains, moss growth, and accumulated organic matter that can reduce panel efficiency by 10-15% if not addressed promptly.
