Our Story:

“About 2 years ago I installed 23 solar panels on my home in Carlsbad, CA. Everything was going fine until I started to notice my output slowly decreasing. I adjusted for seasonality and shorter days but there was still a significant drop. What was going on? I did some research and found to my surprise, that over time, dust and other debris accumulation can cause up to a 30% drop in solar panel output. After having my panels cleaned , I discovered an immediate 15% increase in output. And this 15% translated to $500 in cold hard cash savings per year. This is why we started SolarTidy. Our mission is to optimize each of our customer’s solar panels for maximum output and save them a ton of money, guaranteed! ” – Brian, CEO of SolarTidy

Specialized Cleaning Process & Expertise

Our highly-trained cleaning technicians first do a professional 25 point inspection of all your solar panels. Then you’ll receive a de-ionized purified water cleaning treatment using specialized solar friendly brushes. This unique method provides a spot and blemish free finish and allows your panels to operate at their maximum capacity. In fact, this treatment leaves you panels cleaner 10 times longer than traditional cleaning methods. Finally, we’ll send you before and after pics so you can see our work and compare.

This Saves You Money!

The National Renewable Energy Laboratory estimates that solar panels lose up to 30% of their energy output due to the accumulation of leaves, dirt, dust, and other debris. Our aim is to save every individual client as much as possible. In many cases this means we can save you up to $500+/year or more!* In fact, if you have a 25 panel system and gain 20%, you’ll save approx. $720 per year.  For every $1 you spend cleaning your panels, you’ll receive back $5 in increased solar power generated.

Frequently Asked Questions

Why is solar panel cleaning essential?

Have you had solar panels installed for 6 months or more? When you had your solar panels installed did you consider the importance of maintenance? All solar panels are purchased and installed with the understanding that even though the initial costs of the investment are significant, the future savings are well worth the outlay! However, what began as a good intention may have been a waste of your time, effort and ultimately your money. The harsh environmental elements have the ability to rapidly diminish the efficiency of your solar panels. Without regular cleaning, all of these good intentions could potentially be costing you hundreds of dollars! Not only do the manufacturers recommend it, regular solar panel cleaning is a no brainer once you begin to outweigh the costs of the maintenance to the potential financial losses.

How will solar panel cleaning protect my warranty?

Did you know, most solar panel manufacturers specify regular cleaning as a requirement of warranty periods and claims? Not only do they specify regular cleaning periods, they also specify required methods of cleaning. Harsh chemicals not only damage your solar panels they also have the ability to void your solar panel warranty! Using a SolarTidy servicer, you’ll receive a tailored fit cleaning within the warranty guidelines of your solar panels warranty requirements. Through the use of chemical free de-ionised water, soft bristle brushes and safe handling- not only will it boost the efficiency of your panels, it will ultimately protect your warranty!

Will Rain Clean My Solar Panels?

With the recent rains in Southern California, people often wonder if rain is enough to clean your solar panels? Although rain will provide a minimal rinse off any loose dirt or dust, it will not remove the baked in dirt and debris. To illustrate this, consider what would happen to your car’s windshield if you didn’t clean it for 6 months? The grime and dirt would “green over”, completely blocking your visibility (and light) from entering your car. Think about how dirty your car/windshield gets even after several weeks. And the morning after a rain, remember how your car (if left outside) seems even dirtier than before, like the dust and dirt was just moved around. The fact is that rain contains dust particles that settle and attach to the surface after the rainwater evaporates. When we use our windshield wipers, we clean the center of the screen, but where the wipers do not reach, there is a nasty film of dirt. Your solar panels are in the same condition as the edge of the windshield, where the wipers can’t reach, and likely even worse, since the angle of most solar panels is less than your windshield. Also, the minimal loose dust that does move by the rain will lead to dust accumulating in the lower row of each solar panel, which can cause significant heating. In a string of photovoltaic cells in a panel, if one cell is shaded the others will force current through it, which makes the cell heat up, and will cause a significant decrease in your solar output and greatly reducing the lifespan of your panels.

We’ve recently cleaned many homes/businesses shortly after a rain and the before pictures are just as bad as we find them in the middle of summer! And our customers routinely report a 15-20% boost in power output after having their solar panels cleaned, even days after it rains.

What is De-ionized water and why do you use it?

De-ionized water is water that has been filtered to remove ions. We use de-ionized water as it is 100% chemical free and environmentally sustainable. However, the major benefit of its use is the spot and blemish free finish! This finish allows the panels to operate at their maximum capacity, optimizing their efficiency and ultimately allows all clients to receive the most financial benefits from their investment.

Can’t I just clean the panels myself?

You could, but consider this 1) It’s unsafe for you to go on your roof unless you’re trained and have the proper equipment 2) Spraying your panels with tap water will leave hard water spots, which blocks UV rays and reduces your power output 3) Pressurized water can damage the panels 4) Without being trained you won’t be able to detect weather damage or cracks in your panels 4) It takes time to do it right. Your time is valuable. Let professionals do the job right while you relax!

Do I need to be home when you are cleaning them?

No. As long as we have access to your roof (or where your panels) are located, you will not need to be home. You can also contact us by phone or email to make any schedule changes or coordinate instructions for easy access to the roof.

What if I Can’t Afford To Clean My Panels Right Now?

If you’re low on funds and need a loan to finance your solar panel or window cleaning this month we suggest an installment loan via NationalMoney.net. This is a simple yet effective way to get up to $2500, yet you can request a smaller amount such as $200-$300 to cover the costs of cleaning your solar panels and windows. Read more on how installment loans work, and how and when you should use them.

How often do you recommend I should get them cleaned?

There are endless environmental factors with the ability to cause a build up of dirt and grime on your panels. For these reasons, having your panels cleaned 2-3 times per year is adequate for most residential systems and is also recommended by most solar panel manufacturers. Regular cleanings will ensure your system is performing at optimal levels throughout the year.

Can you clean my windows too?

Yes. We can clean your exterior windows too, leaving them amazingly spot-free. Packages start at $100! Please see our Window Washing page for more information.

Are you licensed and insured?

Yes. SolarTidy has a $2 million general liability insurance policy and $1 million in commercial auto insurance. This means that your home and your panels are fully covered should any damage occur during the cleaning process.

See our Terms of Use Policy for more information.
