Solar Panel Cleaning

Solar Panel Cleaning

Clean solar panels generate more electricity, which means more money in your pocket! They also look better when they're shiny and clean. If you don't do this often enough, the performance of your system will be decreased because of the repelling layer of grime on them. For this reason, periodical cleaning is extremely important if you want maximum results.

Following are 7 reasons why you should clean your solar panels regularly:

1. Generate More Power

There is no doubt that cleaning your panels will increase their overall efficiency. According to many statistical observations, this efficiency and performance improvement can be dramatic, up to 21% in residential arrays and up to 60% in commercial installations. So it's the best way to ensure that your panels are prepped for maximum efficiency. Regular cleaning can make a huge difference in how much power your panels generate!

2. Improve Your Return On Investment

Return On Investment (ROI) means how fast your panels pay themselves off. There are many factors that go into this calculation, and each solar system in unique. However, clean panels generate more energy, which means more money you can use to pay off your investment in solar panels, resulting in a higher Return on Investment.

If you're selling power back to the grid, this means you may owe nothing on your monthly bill, and get a larger year end credit from PG&E. We have clients who've noticed that they no longer have an electricity bill when they keep their panels clean, but they owe money when their panels are dirty!


3. Warranty

Many solar panel installation companies as well as manufacturers have specified regular cleaning as a warranty condition. You may not be covered by the warranty if there is no proof of regular cleaning. That's why regular cleaning is recommended if you want to be on the safe side in case there is a malfunction at some point.

4. Rainwater Doesn't Do The Job

Most solar panel owners don't clean their panels after it rains because they think they don't need to because the rain water will do it for them. But that's not true. Similar to how you need to clean your car's windshield more often during the rainy season, your solar panels need to be cleaned more often as well. So, it is recommended that you don't rely on rain water to clean your panels automatically, because it just doesn't happen.

5. Increase Durability

There are lots of soft grains of sand, dust particles, and debris in the environment. These will eventually build up and contribute to wear and tear when you don't clean your solar panels regularly. While it may not be obvious at first, over time your panels' efficiency will decrease and you also risk ending up having equipment that fails much sooner.

6. Aesthetic Appeal

Nobody wants an aged-looking, dirt-covered panel adorning their rooftop. Similar to how important it is to clean the rest of your home, it is also essential to take proper care of your solar panels and clean them regularly. This kind of proper maintenance will make your home more aesthetically appealing to both you and your visitors.

7. Inspection

When you clean your solar panels, you get an opportunity to inspect them as well. Cleaning time is a perfect time to inspect and evaluate the condition of your panels.
