As the proud owner of Superior Solar and someone deeply invested in helping Indian homes switch to clean, cost-effective energy, I often get one question during monsoon season:

“Will my solar water heater still work when it rains?”

The answer is yes, solar water heaters are designed to work year-round. But just like any equipment exposed to the elements, a little care goes a long way, especially during the rainy months of June to September in South India.

So today, let’s dive into how you can protect, maintain, and extend the life of your solar water heater during monsoons.

 1. Understand How Solar Water Heaters Work in Monsoon

Many homeowners think solar water heaters stop working on cloudy or rainy days. Not true.

Our heaters, especially the Evacuated Tube Collectors (ETCs) are engineered to absorb diffused solar radiation. Even on overcast days, they collect enough heat to warm water for household use.

However, continuous cloudy weather for 2–3 days might reduce heating efficiency. That’s when backup electric heaters (included in most of our models) help maintain consistent hot water supply.

 2. Clean the Collector Tubes Regularly

During monsoons, dust mixes with rainwater and sticks to the tubes or flat plate collectors. This reduces sunlight absorption.

We recommend:

• Cleaning tubes every 2–3 weeks during monsoon.
  
  
• Using a soft cloth or sponge with mild soap water.
  
  
• Avoiding harsh chemicals or abrasive materials.
  
  

Our technicians offer monthly maintenance packages too especially useful if your solar heater is on a rooftop that’s difficult to access.

 3. Check for Water Stagnation Around the Base

Flat terraces in cities like Bangalore, Mysore, or Tumkur often see water stagnation during heavy rains. This can:

• Corrode the heater’s base or frame
  
  
• Affect insulation
  
  
• Invite moss, insects, or damage over time
  
  

Ensure your drainage is clear and water doesn’t pool around your system.


 4. Test the Backup Heater

Most Superior Solar models come with an electric backup for cloudy days. In July and August, test the backup once every few weeks to ensure:

• The switch is functioning
  
  
• Power connection is safe and insulated
  
  
• There’s no water seepage near the plug point
  
  

This ensures you have hot water even on the dullest of days.

 5. Schedule a Professional Monsoon Check-up

As a Superior Solar owner, I always recommend a mid-year service check, especially before and during monsoon. Our trained technicians will:

• Inspect tubes and panels
  
  
• Tighten fittings and insulation
  
  
• Test sensors, valves, and thermostat
  
  
• Ensure leak-proof joints
  
  

You can book this directly through our website or customer helpline. We even provide AMC packages for peace of mind all year long.

💡 Bonus Tip: Cover the Collector When Not in Use

If you’re going on vacation or won’t be using the heater for several days, consider covering the collector tubes with a UV-protective sheet. This keeps them clean and reduces mineral scaling from stagnant water.
