Solar panels are designed to last for decades, but just like any other investment, they need care especially during the rainy season. While rain may seem like a natural cleaner for your panels, heavy showers, storms, and moisture can create challenges that reduce performance and efficiency. By taking the right precautions, you can ensure your panels continue generating maximum power even when the skies are cloudy.

Essential Tips for Solar Panel Maintenance in Rainy Season
1. Regular Cleaning After Rain
Rain doesn’t always clean panels—it often leaves behind mud, bird droppings, or residue. Gently clean the panels with soft water and a microfiber cloth to ensure maximum sunlight absorption.
2. Check Wiring and Connections
Moisture can lead to rust or loosened connections. Inspect all cables, connectors, and junction boxes to make sure they are properly sealed and secure.
3. Inspect the Mounting Structure
During rain and strong winds, weak mounting can cause panels to shake or tilt. For GI (14-gauge) or Aluminum (2.5mm) structures, ensure bolts and joints are tight and corrosion-free.
4. Ensure Proper Drainage
Standing water near panels or inverters can be dangerous. Make sure water flows off the roof and doesn’t collect around the system.
5. Protect Your Inverter
Your solar inverter is the brain of the system. If it’s IP21-rated, keep it indoors and away from moisture. For IP65/IP66-rated inverters, ensure the outdoor installation is tightly sealed and elevated above ground to avoid water contact.
6. Trim Nearby Trees
Overhanging branches can drop leaves and water onto your panels, reducing efficiency and creating cleaning challenges.
7. Schedule Professional Maintenance
It’s best to get your system inspected by certified experts before and after the rainy season to identify hidden issues early.
