Cleaning Solar panels

That is one bizarre layout. Is that a house, guest house/bath house, garage and workshop?

Do they normally pitch roofs from end to end in your neck of the woods? In my area they pitch the gutters.

Coors light on the worksite? They staying lean and mean?

The window cleaner forum might have some guys familiar with cleaning them since it’s glass.

At one time this site sold a soap designed for solar panels. Not sure if it still sells it or why it would be better than Elemonator or SlowMo.

Very nice. Thank ya sir :+1:

Yeah it’s different for sure. The dark gray building has a gym behind the garage door I believe and the rest of it is the pool house. You don’t even want to know about roof pitches in my area. They’re literally death traps.

I have poked around over there but for some reason I can’t get the search bar to actually give me thread results. It only shows products they sell.

Out of curiosity, are the painters coming back after you clean? I don’t know how you can clean that concrete and mortar splatter off without discoloring the paint on the sides.

Just to check and get feedback from you on how to tackle some of this:

The dust I wouldn’t be concerned about, but I wouldn’t scrub concrete dust as it has fine particles in it that will scratch everything. I would “flood” it off the surfaces that scratch easily like those window frames then microfiber towel it flipping my towel often. Is that what you are planning? For the sides where the concrete splatter is at I would think most chemicals would fade some of that newer paint, and any scrubbing would remove paint/scuff it. I haven’t done concrete splatter removal on paint, just checking for future knowledge. I’ve done some experimenting at my house and have found concrete dust will put fine scratches in shiny metal surfaces if scrubbed, but I am not an expert PW. Looking to learn something here.

You’re spot on about the dust. It will definitely scratch things (not to mention it’s horrible for your respiratory system) and my plan is basically exactly what you stated. The mortar splatter easily flaked off with my fingernail so I’m hopeful that a good soak with surfactant will loosen it enough to rinse away. If not, I have some chemicals to get it off but I’ll have to address that with the customer if that does happen. My thoughts are the paint is very new and very smooth so I don’t believe the splatter has much to adhere to. We’ll find out I guess.

I rinse them off with the x jet first to remove all the loose dust and debris. If there’s chunks of stuff stuck to it can use to up to 1000 psi to shoot off. The problem with solar panels is they look like crap after they dry if you just use even a wfp and di water. I do the step above and then use Titan Solar Gleam (special soap for solar panels) spray it on (I use my battery portable sprayer) agitate and then rinse off with DI water for spot three finish. For some reason if you don’t use that stuff they always look like dirt comes right back after it’s dry, this makes it so it does not look like that. Also, just buy the quart size you literally need just one small cap full for a gallon. I can clean about 10-12 panels with 4 gallons. A cap full is 1/4 oz. so one oz per 10 panels.

Nice! Just found a gallon of that stuff on the jungle website for $28. Thanks guys @Seandz and @qons

Oops sorry that’s the quart size.

I bought 4 quarts two years ago, I only used a pint so far
