Do I need to turn off the battery pack or anything else before cleaning the pa els? Your video is very informative, Thank you

Stop this BS dude. With Adidas sneakers on the roof. Tap water sqeege😂 just dont😅

I want to clean my solar panels do I have to shut off the power?

this video is mis informing you about rising tap water. calsium build up in AZ water is known to hurt the panels

Why wasn't the visitors wearing hard hats? It was still an active construction zone.

My 3.6kw system is down to 2.8. Lichen is my enemy, thank goodness I opted for 2 velux windows or cleaning it would be impossible. White vinegar is a good natural cleaner but no brush will shift the lichen

Rain water

Wrong, tap water will leave spots, warranty nil and void chemicals. Nuts. Yes short term will clean, but will degrade your panels. 😮

You said not to use a pressure washer ,but you end up using it in the video ,if am right ?

Can I have your WhatsApp number?

First

Even if we turn off the DC on the inverter before cleaning panels, are the panels still live from solar they are receiving from sun and cleaning with a metal handle brush or squeezed can cause a shock ?

Hello, Thanks for the video. I know you mentioned best time to clean solar panels is in the morning when the temperature is low to avoid the cool water on a hot weather from shattering the solar panels. What if your using a steamer? Can you get away with cleaning solar panels at time despite the weather temperatures ?

Deionized water and NEVER a squeegee and never use soap.

Will alcohol be bad?

How about 320 psi or below 600 psi ryobi pressure washer

What is the best way to contact Jinko customer service? I have sent online forms on their web and called and no response. Working on a transfer of ownership.

I have watched several videos & this one is the only one stating to NOT use soap... all of the ones I've warched are using a concentrated auto soap.....

I want to know which kind of conector has Jinko Solar 480W JKM480N-60HL4-V N-type Black Frame, it is not information in DS.

Thank you very much for the info. I haven't wash my panels for two years but I'll do it soon. Blessings..

should i turn off the inverter before start the cleaning ?

I been reading some of the responses on this thread and I must say there are some missing details that need to be considered. 1. I must state that Solar Panels are devices that convert Ultraviolet Energy into Electrical Energy. Because they are Electrically Active Devices, an untrained person could literally become energized and Injured if he or she is unable to determine if there are insulation issues on the roof. It is irresponsible to think that anyone can simply just jump on the roof and perform a Roof Solar Cleaning. If you are not Electrically trained - Don't do it if you value your life. Solar Panel Strings can have a Potential of more than 600 Volts AC, when using Micro-Inverters on the Roof. Hire a Trained Professional for this type of Work/Cleaning. 2. Through time, Solar Panels can deteriorate, and many issues can develop that can pose a danger to the person cleaning them, and the roof where they lay. Unfortunately very few people speak of this issues because they lack the knowledge of the many things that can go wrong with Solar Panels. This is something sales reps and installers may not be familiar with. Many of these issues include Cell Hot Spots, De-lamination, Bypass Diodes that will not shutdown once active, causing excessive heat, eating through the Insulation, melting lamination, exposing live conductors and expose contacts that can potentially become a real hazard to the person conducting the cleaning. 3. Issues naked to the human eye - There are degradation issues that required trained & Certified Inspectors with associated equipment besides a brush to asses the condition of the Panels on the roof. A drop in performance on a Solar String does not necessarily is an indication of a Soiled Panel or the result of a Cloudy Day. Since most manufactures offer a 25 year warranty on their Solar Panels, often is necessary to perform a Thermographic Analysis to determine if there are anomalies behind the glass. This analysis is often sufficient for manufactures to replace an undetected malfunctioning Solar Panel that it has been sitting on the roof under the pretense that its performance is due to being Soiled or under-performing due to Orientation or Weather. Hope this tidbit helps many think twice before risking their lives cleaning something that has the potential of hurting them, permanently. Thanks, Miguel Jordan Crystal Clear Solar - FL USA

Thank you!

What is the brush you use can you put an Amazon link

You shouldn’t use tap water, there is chlorine and minerals that can cause damage and hard, water staining and you cannot remove hard water stain off of solar panels you will ruin them

Using an aluminum extension is fine? I can't find a wood one in my area.

Good stuff!

Hi, do i need to turn off specific switch/button before washing the panels?Thanks

Thank you, your work has been very useful to me

THANKS

At what intervals , we have to clean the panels? Once in a month or more than that

Yo straight to the point! Underrated should have way more views. Thank you my guy! Next diy to attack at my home! More tools to buy 😎. Def sub

Once a year!!! Isn't this dangerous in terms of microcracks?

Mini (Winter) Solar Tip: You can gradually turn down a boiler and all other hungry electricity consumers with the "5000W dimmer". Ebay €7. I run 5 dimmers in parallel on an 850W inverter. Kettle 2.2KW at 150W runs 12 hours a day, so the water is always hot. The room is also nicely heated. 2.5KW washing machine runs in parallel with dimmed to 200...400W. Iron, dishwasher, oven, electric heater, coffee machine, all internal heating are throttled with me. Videos about it on my channel ruclips.net/video/eC2olbCBhh0/видео.html The inverter stays cool, quiet and the MOSFETs remain intact because extreme current peaks no longer arrive at the inverter. Now every Mini PV Inverter is enough to sell large devices. So, with the dimmer, all internal heaters/devices can be converted into base load devices that stay almost permanently ON, drawing very little current directly from the PV. With a wattmeter / energy cost measuring device you can then measure this perfectly in order to set the dimmer optimally. A little hint (for everyone else): Energy cannot be saved. So if I want to boil my water, I always have to use the same amount of energy for one liter. Christian's method relies on a longer period of time with less power in order to be able to use the power provided by the PV as efficiently as possible - so consumption peaks are intercepted. In the end, the energy consumption should even be (slightly) higher due to the interposition of the dimmer, but it doesn't matter, since more efficient coverage by the PV system and therefore better use of the self-generated energy.............

Can you comment on the use of deionized water vs tap water, please.

I was waiting to hear a claim of "up to 40% improvement" like some of the other vids, but this busines owner is honest. I didn't clean my panels for about two years until this week and my improvement is 4%. Also, you don't need de-ionized or distilled water, it would be nice, but not noticable in improving output. I also use an once of car soap per two gallons of water and a soft brush. The minimal soap helps cut the crap and the water sheets off better. My info is from recording panel output ratios, then cleaning just two panels and comparing the ratio of those two clean panels to surrounding dirty panels over the course of several days.

How to clean solar panel at a 1 MW plant?

Hi, can we dilute vinegar with water for very dirty panels

What licenses do you need to start a solar panel company in California do you need a contractors license?

Solar panel cleaning time information pl

You should have use soft water 💦 it makes a big difference

Thanks for the insight.considering to try this type business

I am planning to buy ''Bifacial 78TR-G4b'' modules for my roof (residence). I would like to ask why do you classify those modules only into ''C&I/Utility''? Just because they are bigger and heavier? One may take it as you do not advise bifacial modules using residential rooftops.

Great video!

Can't wait to start working here in 2 weeks. 04/29/2019 start date!
