The rainy season brings much-needed relief from the summer heat, but it also comes with heavy showers, high humidity, and occasional storms. While solar panels are built to withstand harsh weather, homeowners must take some precautions to protect their investment and ensure uninterrupted power generation.
At VMJ Solar, we always educate our customers on how to maintain their systems during monsoons for maximum safety and efficiency.
Regular Cleaning and Inspection
Rainwater does not always clean panels properly. In fact, it can leave mud, dust streaks, and bird droppings that block sunlight.
- Inspect panels after heavy rains.
- Gently clean with soft water and a sponge if dirt remains.
- Avoid harsh chemicals or pressure washing.
👉 VMJ Solar offers maintenance services to keep your panels at peak efficiency.
Check for Waterlogging Around Your Home
Water accumulation near the solar inverter or battery system can be dangerous.
- Ensure inverters are installed in a raised, indoor, or waterproof cabinet.
- Keep wiring elevated to avoid contact with floodwater.
- Regularly check rooftop drainage to prevent pooling under panels.
Inspect Mounting Structures
Heavy rains and strong winds test the strength of mounting structures.
- Check for loose nuts, bolts, or rust.
- Ensure the tilt angle allows rainwater to drain off easily.
- Call professionals if you notice any instability.
Protect Your Solar Inverter & Battery Backup
Place inverters and batteries in dry, ventilated, indoor spaces.
Use surge protectors to safeguard against lightning and power fluctuations.
Hybrid/off-grid users: Ensure batteries are properly insulated and serviced.
Schedule Professional Maintenance
Before and after monsoon season, get your system checked by a certified solar expert.
- Electrical safety checks (wiring, earthing, and fuses).
- Panel performance testing.
- Preventive maintenance for inverters and batteries.
Monitor Your System Performance
Most modern systems come with solar monitoring apps.
- Track daily generation levels.
- Watch for sudden drops after rain (may indicate dirt or shading).
- Report unusual fluctuations to your installer.
