Tips for Maintaining Solar Panels during the rainy season

Monsoons in India last for about 3 months from July to September, and bring in intense rainfalls across the country. Solar panels require sufficient sunlight to generate power that can be used comprehensively for daily usages. The catch is during the monsoons, the average solar power generation comes down to 40% from a sunny day’s comparison.

In addition, the maintenance of such solar panels in rainy season requires component wise attention as opposed to just the panels. This is because of several factors and water leakage issues, which could damage the solar panels and all the associated components alongside.

Need for Maintenance

Monsoons bring the desired amount of rainfall in a season across every single year. Solar panels in the rainy season tend to generate lesser power output because of the cloudy weather, which is prevalent during monsoons. However, accumulated water and moisture or even surfaces require cleaning and tightening of components. This ensures the reduction of hazards that poses a threat to damage the control panel. Moreover, mounts and components might be susceptible for damages like rusting or corrosion, which again poses a significant threat.

This brings the need for frequent maintenance and tips. These can mostly be done yourselves at home and require minimal intervention or risks. Except, where you require professionals (which we would assist). Without further ado, let’s explore the tips to maintain solar panels in the rainy season.

Tips for Maintaining the Solar Panel System

Here are a few things to check to maintain your solar panel system:

1. Panel Surface

Conduct an intense check of the solar panel in the rainy season after an intense rainfall has just concluded. This would allow you to inspect the surface having any debris or particles getting stuck. In this case, you can use plain cloth to remove the debris completely off the surface and make the panel work as efficiently as before. Although the process is not recommended for normal rainfall, we recommend doing a small panel check after storms or heavy rainfalls.

2. Inverters

It is imperative to monitor the condition of inverter systems. This is a special case that off-grid panel owners require to keep a track of. Although the power generation would almost certainly be less than during a sunny day, the condition of an inverter failing can be monitored using solar power apps. At Freyr Energy, we provide the Solar App, which tracks down the top-to-bottom performance of solar panels and essential components. It gives information on power generation and the performance of inverters. If you find the power generation hasn’t been restored even during non-rainy days, it’s better you seek professional assistance.

3. Mounts and Components

The solar panels are installed over mounts and the structure of these instruments supports the panels for years to come. Therefore, the probability of these mounts corroding or getting degraded isn’t an impossibility. Conduct a visual inspection on mounts and check for any corrosions or crack marks before the downpour commences on the solar panel in the rainy season. Afterall, structural positioning of a solar panel is key to ensuring longevity and top performance.

4. Monitor the power generation

Much like tracking the inverter performance, it’s easy to monitor the solar power generation from time to time. The monitoring of performance drop and power generated. In addition, you can check with the previous data and check if the PV panel performance has dipped or not. In the case where inverters and solar panels don’t produce positive results on a sunny day for a few days straight, it’s recommended to seek assistance.

5. Vegetation on panels

Monsoons lead to plants and bushes growing reasonably faster. This tends to block the path of sunlight and hinder the performance of solar panels in the rainy season. We recommend trimming the branches and bushes to ensure there are no hindrances when it comes to direct sunlight. 

6. Contact Support

Customer support service from top panel providers like Freyr Energy provide a comprehensive assistance for these situations. The consumers can lodge a service request, and have a word with the experts for their visit and check for pre solar panels in the rainy season inspection.

Final Thoughts

In the end, we at Freyr Energy encourage our consumers to take the help of the Freyr Energy app and conduct visual checks and inspections before monsoon. This would ensure the longevity or performance of solar panels in the rainy season isn’t compromised.

Frequently Asked Questions



Yes.Solar panels work comparatively well during the rainy season. If not for a complete sunny-day like performance, it surely does half the record. So to answer your query on “does solar panel work in rainy season”, the reply is yes.

Yes, it surely does. But the generation would be around 30-40% rather than on a sunny clear day.

A rainy solar is the time where a solar panel performance is lesser thanks to a cloudy weather cover or even rain. The panels don’t work that effectively most of the time.

Yes. The solar system in the rainy season gives an optimum output, which in practicality is not the highest, but enough to do a job of backing it up.
