I'm starting on the ground level with a company cleaning solar panels and we are using regular water and squeegee to start. it's the cheapest way to get the business going. Good tips to be careful not to scratch the panel while using a squeegee. always rinse the panels with high pressure water to remove as much debris as you can before brushing as well. Any other tips Tim?
This panel can put out close to 100 watts ru-vid.comUgkxOqI2yqX0XVrhR2BMJciTWrHJpG8FhJyg when positioned in the appropriate southernly direction, tilted to the optimal angle for your latitude/date, and connected to a higher capacity device than a 500. The built in kickstand angle is a fixed at 50 degrees. Up to 20% more power can be output by selecting the actual date and latitude optimal angle.The 500 will only input 3.5A maximum at 18 volts for 63 watts. Some of the excess power from the panel can be fed into a USB battery bank, charged directly from the panel while also charging a 500. This will allow you to harvest as much as 63 + 15 = 78 watts.If this panel is used to charge a larger device, such as the power station, then its full output potential can be realized.
So instead of using tap water or pure water, how about just cleaning panels while it's raining? Rain water can't be that bad for panels, because they have to deal with it constantly, so just use a brush in the rain? Tell me I'm crazy. Obviously, I'm talking from the point of view of a PV owner who only has to do this every year or so, not a PV cleaning business.
If you live in LA, that's kinda not an option haha. I install solar panels professionally but most of the ones we either go to work on are absolutely filthy and require more attention. I have a side hustle cleaning them and do use a filtration system before I even scrub (yes I use the correct microfiber towels, cleaner and solution when needed since you can only use a certain amount of psi if using a pressure washer or risk damage to the panels which I don't go past 1k since it isn't necessary anyways).
Yes, you need a mixed bed resin DI tank. It will not leave spots unless you do not thoroughly clean the panels or do not rinse well enough. There's a company named On the Go that sells them online. They are not cheap, and the resin needs to be replace once used up. The lifespan of the resin depends on your water source.
I'm about to clean our panels for the first time. I was about to do 3 out of your top 5 mistakes. So I thumbs up and subscribed. I cannot wait to LEARN from you. Thank you for sharing.
You are 100% welcome, and thank you for the support. Every Tuesday at 3pm the SPCF team goes LIVE with info, education, stories, and more. Check it out.
I would assume it depends on what type of panels you have. My solar installing company just happens to also maintain and clean the panels for the last 10 years they have this big massive 500 gallon tank that they fill with water and Rain x I've never had a problem my panels are just over 10 years old still look they did the day they was installed.
Maybe to eliminate people from questioning your expertise, you could touch on how the manufacturer recommends cleaning some of the most installed solar panels. I did a quick search about manufacture recommendations and it confirmed most of everything you are saying.
Thank you. Truth is... My wife is actually annoyed with me talking about my work stuff. So, I made a channel on RU-vid, wrote scripts, got in front of the camera, recorded, and then edited on Premiere Pro from Adobe, which cost me money monthly. I did all that so I could have conversations with strangers online via the comments on my RU-vid videos. Who is the loser now MOM?!?!?!
If you use a large soft brush and soap you can certainly use a squeegee and regular tap water. Distilled water is overkill. The squeegee will wipe away any possibility of hard water stains. And you can use a towel to dry and excess water.
How do you clean cluster of solar panels? Have you consider the dangers of solar panel cleaning, or are you just talking out your ass? What do you know about solar panels? What have you considered as far as voiding the warranty?
One very important thing that this video did not mention is to find out how to probably turned off the solar system before cleaning them to avoid injuries or death!
I'm calling to have mine cleaned; they haven't been cleaned since installed in 2015! I so want to ceramic coat these things, but I'm not sure if that would be good for the surface or not.
Solar Panel Cleaning Friends hello, thanks for the info. I am a college student doing a report on the solar industry in the states. I would like to ask if it’s ok with you to use some still shots from your videos in a 90 second video I’m working on? Not your entire content, not for my entire video, just a few still shots of the equipment and technique
My biggest fear is splashing cold water on hot panels, and thermal shocking the glass. If I were to clean panels, I would want to do it early morning, late evening, or best yet, during a overcast rainy day. Rain water may actually be better than tap water. Rather than using a squeegee, I would rather use a soft brush, or a micro fiber cloth. A squeegee may be necessary if scraping off bird deposits. Having a cell partially covered can lead to hot spotting of that individual photovoltaic cell within a panel. It is necessary to make sure there isn't a single leaf, or, any other opaque debris covering a cell.
@@sweetvuvuzela4634 True. Rain is perfectly distributed, which cools the panels uniformly. I'm talking about a concentrated splash of cold water, like from a garden hose, or a bucket, which chills only one small part of a panel very suddenly. If you have to clean during a hot day, using hot water might be the better choice, to reduce thermal shock.
@@jjk2one panels won’t get that hot unless they are in an oven in the first place and why would anyone place panels in an oven and splash water on them? If your that scared wash them in the dark or wait for them to cool.
Francisco. What's up? Glad you found the RU-vid channel. Now I am going to introduce you to door to becoming a solar panel cleaner. Plenty have left their jobs, started a solar panel cleaning company, and created a new life for themselves. It's a great business to be in. Next, go to Facebook.com/Groups/SolarPanelCleaningFriends, and join the #1 community dedicated to solar panel cleaning. We have a team that helps me run the group. Answer the questions, but make sure that you add that you met me while I was out cleaning, and I that I told you to join.
How do you recommend cleaning paint overspray off solar panels? I have SUNPOWER panels and the cleaning company wanted to use some kind of cleaner oil, with a razor type tool?? I've only read of a plastic scraper being used?? Thanks!
Yeah, that plastic scraper idea actually comes from me and a really old blog post I wrote years ago. Water, a little Dawn for lube, and a plastic scraper. Go gentle, and be nice. If you are at the wrong angle for scraping? You'll immediately know. It will make a terrible sound. That's it.
Total dissolved solids. there is no Iron, Calcium, or Sodium, or Potassium in rain water. Those elements do exist in tap water, and when the water evaporates, those elements remain on the panel as scale. Once that happens, it is much more difficult to clean the glass. That scale doesn't just simply dissolve, and run off during the next rain.
Well, if you are not a professional cleaner from a professional cleaning company? I would hire a professional because of the warranty of my pv modules. Now, how would I remove it? It is a process of water, a small little dab of Dawn dish soap for lubrication, and a plastic scraper. I don't like to use liquids for paint removal.
Air conditioner condensate water would be a much better choice than tap water, since it's almost the same as rain water. (minimal total dissolved solids)
Using common sense would tell you that regular water and light detergent ones with no ammonia or acids would do the job. If regular water will do harm then snow rain and acid rain will destroy panels. Looking at how quality panels are made, they are durable and not delicate. Pure water and other gimmicks will create jobs and make money. The better way to sell such services is to explain all the safety reasons you don’t want to DIY or sell to those not having time.
Awesome. Let’s do this. First off, look the Anti Reflective Coating. This is a thin film placed on top of the glass. It not only keeps the solar panels from annoying your neighbors, but it also helps to absorb the sunlight. Breaking down the ARC is a bad idea because you’re butt hurt, but do what you think is best. Acid rain is good for solar panels😂😂😂 Rain does not clean panels. What else you got? Let’s do this.
You have to consider the calcium, potassium, iron, and other dissolved solids in tap water. When tap water dries, it leaves those and other elements behind as scale. That scale doesn't readily dissolve again. Rain water doesn't contain those elements, and wont spot or scale the glass surfaces nearly as much as tap water. Salt softened water isn't much better, it just adds Sodium to the mix.
Soo, ummmm.... where do you get pure water to clean the panels? Do you use an in line filter or softener? Softening chemical that attaches to the hose?
There is no inline softener at all. You have a few choices when it comes to purifying your water for cleaning solar panels. DI, RO, DI/RO combos, or you can use the Solar7 from Ph7. That is what we use clean with. DI, RO, DI/RO combos filter out bad elements in water to obtain a 0 tds level. This low 0 ppm of total dissolved solids creates a water that dries with a spot free finish. No soaps, chemicals, or cleaning agents are needed to clean solar panels. The Solar7 filter from Ph7 restructures the water to make the solar panels hydrophilic. This is known as "good-wetting". The water dries evenly and smooth. Living a beautiful finish.
Unfortunately I can't afford to have my panels cleaned. So, majority of the time I let mother nature clean my panels. I have 62 panels and my roof on the house is very steep and I just don't like being up that high. The panels on my outbuilding I actually cleaned for the 1st time this year. I used a garden hose and tap water with a soft bristle broom. They looked great... For Approximately 1 day. Then dusty again the next day. (waisted time) Not sure how I could get a rock on my roof but I will keep my eye out for them lol My question is... Is there away to keep the dust from collecting on the panels? ( then I wouldn't need to clean them )
There are ways of slowing down the accumulation of dust, dirt and debris on solar panels. Email me at SolarPanelCleaningFriends@gmail.com. Let’s talk more. I’d like to help you out.
Because the rain doesn't scrub the panels. Same reason your car isn't clean after it rains. The car wash you drive through scrubs it and rinses with purified water at the end.
Yes. Try to clean as early as possible. Which isn’t always the easiest. I like to say in these situations that you need to bleed the line. Water sits and gets very hot. Let your water run for a minute before cleaning. Do a light mist pre rinse. This will help the panels to cool down. It’s a tricky cleaning. You’re on the edge of cracking panels
Well, I don’t suggest using RO. It’s kind of expensive. DI tanks are the way to go. 1/2 cubic foot tanks are a great starting place. DI resin is easy to obtain, and replace.

What are your thoughts on a really fine grit sandpaper (2000 grain) on a disc sander. This could help make sure the light meets a very smooth surface so it does not loose so much energies.
That Pug at the end was precious! LOL! Good tips on cleaning those panels!! So you scrape pollen and bird poo off with scraper but won't use a squeegee? Salright, keep 'em coming, Chris!
The best tool is a light weight patio cleaner powered by a jet was pump , don’t let the spinner near the edge it’s safe when running flat only , that tool is awesome , some lychnis are total arseholes to get off the top washes away but the root remains so hit that sucker with bleach or a ligh plastic scraper , I have personally washed a 5 meg farm with millions of Those stubborn fuckers left to grow for years because the tight arse owners will not spend , in the end panels fail and they pay through the nose lmao ,
great video! Can i use tap water for cleaning/rinsing process and then do a final RO rinse? I have an under the sink RO system that makes enough to set aside 10 gallons. Is the issue with city water a chemical reaction or just mineral deposits when it dries?
@@annabellecarter6067 it finally rained here in LA and I was able to clean my panels with a brush in the pouring rain. Tomorrow I’ll see how I did. I just bought the house and I think the panels had 10 years of residue on them.
Yeah I agree. I was wondering the logic here...rain water isn't "pure water" and it lands on solar panels all the time. Also wouldn't damage factors be dependant on the type and quality of the solar panel.
Mainly from my 9 years of experience, but also because I have tried a plethora of cleaning methods over those years. Let’s be clear. Types of cleaner, or pure water will not effect the energy output if a module, or the “data”. As you have so eloquently stated. There is a different outcome that you are conveniently forgot. Using a cleaning agent, or cleaner chemical to clean solar panels can causing scaling on solar panels. Possibly work it’s way under the frame, and damage the silicon. There are cleaners out there that people sell. Not sure why anyone would buy them. Pure water is all you need. Even if you get those cleaners??? You’ll still need pure water. Other wise you could... 1. Weaken then of module causing a reduction in the lifespan. 2. Multiple exposures to hard water will cause scaling. Which will permanently cause a reduction in energy output in panels. Damage factors will vary depending on manufacturers, and if you think you are safe because you have panels like Tesla? Search Walmart and Tesla solar panels. You’ll find some interesting videos.
@@SolarPanelCleaningFriends dude. do you talk to your customers like that? do you even have any paying customers? you're condescending, insolent and just plain passive-aggressive. I can see why this video has more dislikes than likes. "food for thought."
That’s a great question. Basically whatever breaks down to a 40%-50% profit margin for your company. I will say this. Residential is more per panel than commercial.
If you had a 2 mw solar farm to clean, and two water fed brushes, what would the water required look like? What would be the ideal GPM to be economical yet effective (maximum efficiency with low labor inputs)?
Water Bowser + Quad bike or Small Van / Battery System or if in a van you can run the van with a Water pumped through a 0 TDS canister or known as a DI Filter. You can also fill the bowser with DI'sd water and save on running the filter in the field if you wanted to. Clean with a soft brush using a pole. Really that simple... I started a soft washing company in the UK for doing sites like these and I also do domestic dwellings... Really is easy ;)
@@SolarPanelCleaningFriends Yea and then it rains the next day. You can't stop the rain. So I would just brush them and use tap water. That what we have been doing on our 9630 watt Enphase System. It's just hard to scrub good with the brush and long pole. What do you suggest for that? Add a little weight to the brush?
Cool. That actually will void your warranty. While you are not “fussy” now? Wait till you have an issue. By the way, over half the owners out there have installs with issues they have no clue about. When is the last time you’ve had an inspection done? I installed for three years. In addition to cleaning there is the a visual inspection that should be done at least 1-2 times a year.
Been doing this over 10 years, but you are totally cool to do whatever you feel good with. I’m not here for customers. I have another company. SPCF was created to give knowledge to cleaners and solar panel owners.
@@SolarPanelCleaningFriends I installed my system myself, so I'm not counting on any warranty - and with the thousands I've saved over paying (and not overpaying ) an installer, I can replace my own system two times over and still be in the black. Again, I'm not fussy, and thanks for being cool with it.
I may have missed it, but why don’t we want to clean with regular tap water from a hose? What kind of instrument/tool/brush should we use to clean the panels? Thank you.
using streak-free cleaner with tap water does the job just fine. i'd be more interested in using that device you have on commercial to get the job done faster
It may do the job “just fine”, but that’s not all that is taking place. There really is no reason to use a cleaner, and the cleaner certainly does not remove any of the hard elements in the water. In fact, scaling can occur from long term exposer from regular tap/hard water. Food for thought.
All I heard was you can scratch a solar panel and thats a problem and a problem is an issue that causes even further issues. Who knows is right my man.
888 upvotes vs 807 downvotes... something tells me people are aware that this type of video (giving false info) was published so that people will pay those associated with this group to do the work when in reality, yes, you can do it yourself (hose/tap water and all). hard water (calcium) does not build up on these panels. The coating prevents this, outright. The coating is not easily scratched either, you have to deliberately grab a rock and carve into it to make a significant mark.
I am 100% making a video of this comment. I will tag you in it. That video is a little outdated, a new upgraded video is on the way, but you couldn’t be further from the truth.
Actually, the National Renewable Energy Laboratory found that various elements found in tap water from around country have various effects on modules with long exposure. If you simply did it once? Not a big deal, but repeatedly? That accumulates causing a reduction in energy. Not does it interfere with the uv rats from the sun, it also has the possibility of creating hot spots.
Tap water has minerals in it that is not good for solar panels. The calcium from hard tap water creates a thin film on solar panels after time. This not only lowers the energy efficiency, but it could create hot spots.
Using pure water, soft water or distilled water to rinse is futile, and a waste of time and resources unless your tap water is very hard. Here is why: As soon as it rains or snows, your solar panels are covered with particulate, just like your windshield of your car. When your car's windshield is super clean, what does it look like after a rain? Rain and snow filter dust, and debris from the air and deposit those particles on your solar panels. That is why after a rain or snow air visibility is so much better. All that crap is on your solar panels. Even wind will deposit huge amounts of debris on your panels.
is pure water the same as distilled water sorry if its a ewbie question to ask but my mum wants me to attempt cleaning recently installed panels and well she bought a pressure head washer for the job and being in kenya we are ways off from cleaningg expertise is it alright to use such a nozzle t clean with normal water or do i still need pure water or distilled water?
Actually, distilled is around 0.5 ppm of total dissolved solids. So, I guess it would be fine to clean with. Pure water is basically water with a 0 TDS level. You can clean solar panels with 0-40 tds levels. Windows are 0-10 tds. Now, for the pressure. Be careful, most manufacturers recommend nothing more than 40-50 lbs of pressure on pv modules. This can cause microfacture cracks in panels.
Good ideas but cost of distilled water may make mute having solar panels. As I need to clean them every 3 days because I do watch them after cleaning. A film of dust every 3 days I get. I got some more recently and new ones more difficult to keep clean poly to mono crystal in. But my main problem is a brush well I got sick and tired of having my neighbors auto parked in front of my house and did clean it with a brush my other neighbor complained I was GOING TO SCATCH his car . So I got sick and tired of it and stopped and told him to go park his broken glass dirty auto somewhere else.
a fine layer of dust is probably ok, just don't let it get all blocked from the sun... maybe use a leaf blower to blow most dust away, you can't keep them perfectly clean every day
I use dish soap in a foam gun. Then I will let it sit for a min and rinse of with the pressure washer. It gets all the dirt off. Then I will go in with a chemical to prevent mold and mildew. Using this means prevents scratches and repels the dirt
regular water has ion particles, which will dry and leave a mark in the module. what will happen to a car if you spray it with tub water and not drying it?. the ion particles will dray and will leave a mark. rainwater doesn't have this effect unless there are dust particles in an object.
My first project 10 years ago was 7800 carport panels. I'm good with the way I look. I'm positive it affects some companies, but I'm good. My experience and skill out weighs the aesthetics of my shirt. By the time my crew is done the customer has a report from a visual inspection and a thermal imaging inspection. It's a beautiful, but thanks for caring about my shirt. My wife made them. I love her. She's so talented.
So you like voiding your warranty? Lmfao. Keep using that hard water. That’s awesome. I’m going to guess you are doing DIY and think you are all good. Bro, you are so off it’s funny. Regular water?!?!?! I’m going to let it go before I get mad and rip into your ignorance.
I made this video quite awhile ago. Did the best I could at the time to present information that I have learned in my ten years of professional commercial and residential solar panel cleaning. Time for an updated video. Any suggestions?
Trolls be trolling. Usually at someone else's home using internet service they can't afford because they can't keep a job longer than 3 weeks, but yeah. Utter DRIVVLE. I understand how it must feel coming from an individual whose EDD just got cut off, and is worried about paying bills.
I build more solar panels than u will ever wash. Don't understand me wrong in some point your have good knowledge how panels are constructed.But not enough to talk about materials used to build it. Glass (hardened)is used to cover front and back of the panels.And weather conditions are the major issue regards surface damage(microscratches)which will affects efficiency of the solar panel in period of time.Tap water will not damage surface of the panel as long as u use proper cleaning procedure. Enjoy you evening .
@@woodman687 So what is your proper cleaning procedure? We live in Florida and there is pollen that gets on the panels. Wife and I use a soft brush and tap water from the hose. Our Tap water is very good. I see they sell cleaners on amazon but I think that is a waist of money.
@@droneworks6340 Very simillar to yours. I usualy use tap water and very soft brush. Sometimes only water .I do that every 2-3 years. I know long time but here in Scotland we can't complain about lack of rain.And I haven't noticed any fluctuation in energy production. Florida it is a diffrent story due to sub-tropical climate. Apsolutely solar panel cleaning detergant are a waste of money. My house is two store high, I have my own scafolding tower which is very handy as I can chek my gutters when I clean solar panels.
@@julianlane3561 really. Use regular water on your car. Use that on your windows. Let it dry, and let me know it’s ok. Also, instead of presenting an articulated argument, you choose to use profanity to present your uneducated opinion??? Hmmm… interesting. What happens when that regular water evaporates? What happens when “intelligent” individuals like yourself use regular tap water to clean panels a multiple of times over a long period of time??? Let me guess. Nothing? It’s all good? Lmfao. Let me help you out. Over time the efficiency and lifespan of your modules will greatly diminish. The degradation can eventually weaken the solar cells beneath. You know? The actual things that create the energy. Anyways, let’s talk about corrosion of your expensive panels. You paid all that money to allow hard corrosive water to sit on your panels? Smart. I’m sure you do the exact with your car, right? Hell, why even use windshield wipers???? The wind will take care of it.🤦♂️
@@julianlane3561 I’m not done. In addition to a reduction in the over all efficiency of your system even though you are receiving the same amount of sunlight, which should be a concern, but…. In order to maintain optimal performance, you’ll have to increase your cleanings as you are creating a dirt magnet using regular water.
@@julianlane3561 let’s talk about how regular tap water encourages mold and algae growth. Sounds like you thought about everything…. Accept the important obvious reasonings, but what do I know???
@@julianlane3561 I’m curious if you’ve considered the anti reflective coating that sits on your panels. Yes, it does help to mitigate that annoying eye killing sun shining reflection from the neighbors, BUT!!!! The ARC also helps to increase efficiency by allowing the solar cells to fully absorb the up rays. However, I guess that doesn’t matter because you may possibly have hot spots at this point, but who cares??? Obviously I am teaching others so that I can make money by perpetuating a lie.
@@SolarPanelCleaningFriends I think you’re right filtered water is great but it’s unpractical especially off grid where our water is hard. I watched your video and used your tips on my solar system. It’s nice to do a thorough job, but the panels will inevitably get dirty again within a few weeks or a month. Thanks.
