Due to the upwards angle of solar panels, they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain. This reduces the amount of light hitting the panel and reduces its output. As the projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this build-up of dirt can adversely affect the panel’s ability to meet those projections. So, it is important to clean solar panels in order to protect and maintain your investment.

Regular solar panel cleaning will also help you to make the most of the energy feed-in. Solar panel cleaning has been around for a long time and is suggested by most manufacturer warranties. If solar panels are not cleaned regularly, they will not run at their optimum performance.

So Why Clean Your Solar Panels?: Solar panels are prone to accumulating dirt. Why is solar panel cleaning important? Solar panel cleaning keeps your warranty intact, helps your solar panels produce the maximum electricity, and, more importantly, saves you more money in the long term.

Some solar panel manufacturers and installation companies have made solar panel cleaning a condition of their warranty. Should you have problems with your solar panels, if you do not have proof of regular solar panel cleaning by professionals, your solar panels may not be covered by the warranty. We have made a comparison of solar panel warranties, and the message is the same — get your solar panels cleaned.

Washing Solar Panels Improves Efficiency

On industrial and commercial sites, we have seen increases of up to 60%, and on residential arrays of up to 21%. (Hover over the pic for before & after shots)

We have, for years now, been monitoring the increases in efficiency that solar panel cleaning can bring. We frequently see sizable increases in solar efficiency on agricultural sites of up to 30%. This has been proved by clients who have sent readings to prove solar panel cleaning has increased the output and efficiency of their array. Operations & maintenance departments of solar companies that we have cleaned solar panels for have also reported similar increases in efficiency from solar panel cleaning.

Our own findings are confirmed by the World Academy of Science, Engineering & Technology, which says, “A drop in the efficiency of a solar PV panel is not desired. One of the contributing factors in the drop of efficiency in solar PV panels is the accumulated dust on the solar panel. In practice, dust must be removed from the surface of solar PV panels in order to ensure highest performance.” Solar Energy Power Association notes that dirty solar panels can lose 20% of their energy output. The National Renewable Energy Laboratory puts that figure even higher, at 25%. Recent university research has shown that a dirty solar panel can lose 50% of its efficiency compared to a clean solar panel.

Why Rainwater Will Not Clean Your Solar Panels

solar panels are like windshields — they need cleaned

A good way to illustrate why rainwater will not clean solar panels is by looking at your car windscreen. If you didn’t clean your windscreen for six months, how much visibility would you lose? If left, the grime on your windscreen would accumulate. Even if the car is rained on, the rain contains airborne dust particles that settle and attach to the surface after the rainwater evaporates. When we use our windscreen wipers, we clean the center of the screen, but where the wipers do not reach, there is a film of dirt.

The whole of your solar panel is in exactly the same condition as the edge of your car windscreen because they are both exposed to the same elements. Visibility through your windscreen is lost due to the loss of light. The same principles hold true for solar panel cleaning. It is very important to maximize the light getting into the solar panel and, in turn, increase your financial reward.

Google’s Solar Panel Cleaning Research

the facts behind solar panel cleaning

In California, technology giant Google has a 1.6 mW solar panel installation. The research they carried out on their own equipment reached a clear conclusion that dirty solar panels will have a negative impact on their performance. Fifteen months after their solar panel array had been installed, they experimented with solar panel cleaning. After the first session of solar panel cleaning, their output doubled on some solar panels. Eight months later, they had their second session of solar panel cleaning, and the solar panel efficiency increased again by 36%. After having a solar panel cleaning, all of Google’s solar panels increased their output by at least 12%.

Hired S.W.A.T services to clean the gutters. It was a great experience end-to-end. They were very communicative. They sent a calendar invite and followed-up with regular reminders ahead of the scheduled appointment. Chase carried out the work. He was super friendly, professional and did an excellent job. I highly recommend S.W.A.T and will definitely hire them again.

These guys are great! They cleaned inside and out all of my windows in my 1901 old house, including all of the interior and exterior sills. They also cleaned my gutters of debris. They were actually a bit early which was great. My windows have never been cleaner! Ill definitely use them again.

Using S.W.A T for the first time, I really wasn't sure what to expect. If I could give Chase and by association S W.A T 6 stars, I would. Chase did excellent work and was really so pleasant and respectful toward us and our home. I will definitely hire the company again for other work. Thank you!

Chris & Ty were AWESOME! They were very respectful & courteous. They took GREAT care with our skylights. They took their time, with how delicate the glass is & did not over charge for the job. We will DEFINITELY be using them again! Thank you fellas!

We were very happy with the results of our Chimney Sweep. Chase the technician was very efficient honest and showed us pictures of before and after. We shopped around and they were definitely the best value and we had the best results.

I had a full day of air duct, dryer vent and gas fireplace cleaning! Anthony and Chase did an amazing job!! Super friendly, professional, communicative and very respectful of my home! I highly recommend using SWAT!

I’m a property manager in Denver, and this company is great, especially Guy! Very responsive, professional, reasonable, and they save us a ton of money each year by not having to rent a lift. I highly recommend!

I have been using S.W.A.T. for a number of years. They are reliable and very thorough in their work. The owners are wonderful and care about feedback to enhance the already superb work. I can’t recommend them enough.

I used SWAT for 2 of my apartment communities in Denver and their team did an awesome job. Professional, detailed and great communication. I will definitely use them on a regular basis.

This company is as thorough as I have ever experienced. Chris and Mariza were diligent and went hard for 4+ hours. We waited over a year and it looks like we have new windows!! Thank You

SWAT did an awesome job cleaning my windows. They were able to get me in quickly due to a cancellation, which was so convenient! The team was very professional and efficient. They also gave me some great tips for how to keep my windows clean between professional cleanings. I will definitely be using them again.
