How To Clean Solar Panels | Like a Pro!

I’ll show you How To Clean Solar Panels like a pro so you can improve the efficiency of your investment.

For those of you with a sloped roof, I recommend staying in one spot and using the water fed pole brush I use in the video. You also use an extension pole for your squeegee or just skip this step all together. Cleaning solar panels can be dangerous so exercise caution and good judgment.

Here are the tools I recommend for the cleaning solar panels:

Good video and very informative. The only question, I have, is how often should you clean solar panels? Thanks again for creating this turtorial.

[Maggieismydog]

So you have a 24 ft washing pole and a 1 ft squeegee??? How does that work?

[gregorybarth]

I clean mine with automotive windshield cleaner (rain ex) they sparkle, shed water and the very rare snow we get in Texas

Suppose the roof is too high to feasibly get a hose up onto it, is there any tank-based solution that I could use instead to rinse down the panels?
Edit: answering my own question, I can pull the hose up to the roof using a dog leash and use a 0.1 HP pump to pump it up there. Should get up about 40 ft according to what they say.

Don't use an expandable hose. You will lose pressure in the water fed Pole. if you have hard water this will also leave mineral deposits. Used distilled water or squeegee dry. Also always wet the panel before adding solution to avoid any scratching. While doing any of these one or two times is no big deal doing over and over will cause damage. I do this for a living and charge good money for this because all the steps take an investment and time. The use of the chemicals is definitely spot on. The process here just needs to be tweaked a little to be professional grade.

Hi would you happen to have a link to the pole brush you used

[Dyerboi]

How do you spray the cleaner on the panels from on the ground?

[fauxque]

This should be a how not to clean your solar panels. You have to rinse off everything you can before you try to scrub them. His choice of brush is also a no go, for the same reason you don't use a brush to scrub your car. Not prerinsing the panels means any sand is now an abrasive. Little scratches will be detrimental to your efficiency. If you have to scrub use one of the micro fiber heads with the soft fingers all over it. Use it lightly to avoid scratches. Rinse it thoroughly between each panel. Also don't use a squeegee. Again it causes scratches. Don't use a pressure washer either. Spray them off, gently loosen any dirt, then spray it off for a final rinse. They will dry quickly without squeegeeing them.
Some people say not to wash them when they are hot from the sun because the water could shatter them. I understand the theory but in reality I don't see it. My panels cook in the sun and then get rained on sometimes several times a day and have never shattered.

What do you do when the panels are installed on a roof with tiles? I got 46 panels on 1st and 2nd floor. Worried about breaking tiles

[TheFlashmark]

Can we use high pressure washer to clean solar panels?

[marcelzinho]

Squeegee isnt 24 ft? So u can do the first part with the thing thats 24ft and then still gotta go through circus act to use squeegee? Or do u have any better ideas to access a larger area without moving around on top of the solar panels? Some roofs are filled with solar panels..

[chimaonyeneke]

Please bro can a professional general cleaner do the work of solar panels cleaning job

[michaelmcgrath]

Not my roof. French terracotta tiles on sloped roof 12 metres above ground. No access except by ladder and no attachement points for a sling. I’d need a good cherry picker at least.

[jasonorourke]

Do you disconnect the array at the inverter before doing this? Or an unnecessary step? I was thinking about doing it at days end when the sun has dropped to non productive angle.

[zubairfarooq]

I need to discuss this thing with share any way how I can contact you.

[engchoontan]

there should be an alogorithm for arher/deco/... WiFi routers to sell new big TV.sss and aircraft windows and bus and car andband and..

[SteveBakerIsHere]

I have a flat roof and built my own elevator to get up there. So no excuse for not washing my solar panels.

[MultiJtor]

The brush won’t mess up the photocells, I was told not to use any abrasive tools???? I confused……

[solarcustomerservice.]

Squeege is not necessary, and that cheap nylon brush is junk. You should never use any chemical at all ! If you had the correct brush you wouldn’t need any chemical. Chemicals get trapped under the aluminum edge and can damage the seal.

you have just solved my issue with my RV solar panels - thanks and liking your other videos too
