I accept already written about why it doesn't make sense to pay people to make clean your solar panels. I also wrote it doesn't make a lot of sense to clean them yourself. Once you add in the value of your time, the chance of falling off the roof and killing yourself, and how cleaning panels ordinarily only adds a couple of percent to their average output, information technology is not really worth it.

Simply this article isn't written for people who desire to make economic sense. It is written for people who take pride in having a well maintained organization that will squeeze every terminal drib of energy from the lord's day. It is written for people who want to clean their own solar panels.

And so pay close attending while I cover the finer points of how to make clean solar panels. There will be a test. The exam will be administered past reality and will involve the entire planet trying to kill you.

You don't think I am serious about the entire planet trying to kill you lot? Well if you don't pay attention to what I write nigh safety yous might walk off your roof and do a opposite Newton. Y'all know how Isaac Newton got smarter when something landed on his head? Well, trust me, the opposite happens when you lot land on your head.

Clean Panels When They're Dirty

The best time to clean your panels is when they're dirty. That information is probably not a huge surprise to you. Maybe you lot're thinking I could have skipped this footstep and gone on to something a bit more useful. Just a lot of people exercise their cleaning to a schedule, like clockwork. And like some forms of clockwork, I think these people are cuckoo. If your panels aren't dirty it'southward a waste of effort. Even worse, cleaning panels tin can scratch them and reduce their efficiency. So unnecessary cleaning tin can reach the reverse of what yous are trying to accomplish.

Rain Is Just Bully For Cleaning Solar Panels

Moderate to heavy rain does an excellent task of cleaning solar panels. Panels angled at ten degrees or more will allow pelting will flow downward them and wash them clean and nearly Australian roofs slope at 15 degrees or more. Unless conditions are particularly dusty, if you clean your panels within a couple of months of decent rain you are probably wasting your time.

Monitoring Your Panels

If y'all have microinverters or DC optimisers, which permit yous to track the functioning of individual solar panels, so it is very easy to meet when they may demand cleaning. If an individual console shows a sudden subtract in performance then that's a likely sign a bird has left you a little message. That message is, "I shat on your solar console."

If y'all can only monitor the full output of your organisation so you may be able to use it to gauge when they might benefit from a clean. But it is very difficult to tell as wind and air temperature will bear on how hot the panels are and crusade output to vary. The easiest solution is ofttimes to just look at the solar panels. If you tin can encounter them from the ground, this is pretty damn easy. And if you demand a ladder to run across them, well that'south obviously a flake more damn difficult.

If your panels look spick and span they don't demand cleaning. And if they are difficult to spot under the mounds of bird droppings, then they could probably benefit from a launder.

Get Permission From Mummy Showtime

At this point, before anyone touches a solar panel, to avoid accusations of being, "completely irresponsible" I am supposed to inform you to contact your solar panel manufacturer and follow their instructions for cleaning them.

In addition, you should always habiliment a helmet when driving a car, just in case. And only e'er drive Volvos. But don't drive Volvos powered past petrol, diesel, or any kind of flammable substance. Considering that would be dangerous and we wouldn't want to accept any risks now, would we?

Brushes And Cloths Scratch Panels

On the internet you tin can find advice about cleaning solar panels. Ane gem is to never use brushes, mops, or cloths on your solar panels. And this is why my preferred method of cleaning solar panels is telekinesis.

But if yous neglected your Jedi preparation and are unable to use the forcefulness, then using a soft broom or cloth may be tempting. This is not an unreasonable choice. Just information technology will scratch the panels. No matter how clean and soft the cloth you employ is, at some betoken yous volition get some tiny bits of grit in it, perchance also small to even see, that will scratch the glass. This is why some people follow a strict liquids just rule.

Personally, I hold with this rule. Mainly because I am lazy and using a soft broom or a cloth sounds suspiciously like physical activity to me. That said, careful utilize of soft brushes and cloths isn't going to cause whatever significant damage.

A Tiny Bit Of Scratching Is Not A Big Bargain

Whatever time yous move a castor or a cloth against a solar panel you run the take chances of scratching it. But provided yous are careful this is probable to be insignificant. Ten years ago panels cost over ane thousand dollars each and and then people were paranoid near doing anything that could harm them. Merely gentle apply of a soft brush a couple of times a yr isn't probable to do much harm. And even if after a couple of decades you lot exercise eventually end upwards reducing their output by half a per centum that is not going to add a lot your electricity bills.

Personally, I say just make clean your panels from a distance with sprayed water since that'south the safest option. But if y'all are going to utilize a brush, then I advise getting a soft broom and only use it for cleaning solar panels. Store information technology brush up so it won't collect dust from the footing that can scratch your panels.

Don't Spray Water On Hot Panels

Another bit of advice you may have heard is to not spray h2o on solar panels when they are hot. I agree with this communication. Solar panels are tough so I very much doubt that spraying a hose on a hot one would cause information technology to scissure or shatter, merely I'm guessing you'd feel pretty stupid if you managed to prove me wrong, so it's probably best non to try.

Washing panels early on in the morning time, when it is overcast, or any fourth dimension there is not a big difference between the temperature of the panel and the water you are using will avoid this possibility.

While you probably wouldn't break your panels through thermal shock, using cold h2o on hot panels volition cause them to become through a thermal cycle. This is when information technology contracts due to cooling and and so expands when it warms up again. This puts the joins betwixt components that aggrandize and contract at dissimilar rates under strain and is a major crusade of the deadening deterioration in output solar panels endure over the years. While the deterioration in performance from one rapid thermal cycle would be extremely small for any well made panel, such equally those that are tier 1, it even so doesn't exercise information technology any good.

Tap H2o Is Fine

Professional solar panel cleaners often make a big deal about how they employ purified water to clean panels. They say it will stop evaporating water leaving mineral salts behind and requite a better clean. This is certainly true. Using distilled or demineralised water will prevent streaking and make the panels cleaner. Only they will be cleaner by an insignificant corporeality.

If y'all don't wash your panels when they're hot, which you shouldn't, then almost of the water is just going to run off them. The residue left backside by evaporating tap water is not good, but it simply has a tiny effect on performance. Perhaps merely every bit much every bit one or two days grit falling on the panels.

Subsequently cleaning your panels you tin rinse them with distilled water if you like. Only it won't make much of a difference.

Safety

The almost of import thing when cleaning solar panels is rubber. Because if you don't have condom, what practise you have? I'll tell you lot what – Danger! And danger is cool! Have you lot ever seen a cool person cleaning solar panels? I don't think so. This ways if you want to get your panels clean, you must avoid danger at all costs.

You can download the Safe Work Commonwealth of australia guide to fall prevention here. Their rules on proper ladder use are all-encompassing. If you are going to piece of work on the roof they propose putting upwards safety railings. If that's non applied they recommend using properly installed and maintained condom harnesses.

I know that about of you aren't going to follow these precautions and I understand why. Those of us who weren't brought up with modern safety standards have a tendency to laugh in the confront of death. Unfortunately, we likewise accept a tendency to fall off roofs and land on our heads. And so please, if you lot are using a ladder or going up on your roof, think carefully virtually how to do it safely.

The Safest Way To Clean Solar Panels

The best way to avoid falling off a ladder or roof is to stay on the ground. I highly recommend this approach. If yous tin can see the panels on a single story building and then yous tin can almost certainly spray them with a hose. This is the easiest and the safest way to clean your panels.

Bird Poo

Bird poo is a trouble for solar panels. With string inverters a unmarried bird poop can non only lower the operation of the panel information technology lands on, just the other unsullied panels on a string. And most systems in Australia use string inverters.

Fortunately, even if yous don't make clean your panels, bird poop is not a permanent trouble. Rain will remove it. If you lot don't believe me, go outside and look at your roof. Is information technology covered in a layer of bird poop? Probably non. This is because rain that is heavy plenty washes it away.

If you have tree branches overhanging your roof, then yes, in that location may be a layer of bird poo. If they overhang your solar system, and then you could have a major poo problem (likewise as a major shade problem).

How To Remove Bird Poop Without Harsh Scratching

Update 13 January 2022: When you hose off your panels, you desire the water to autumn down on them like rain. It'due south non a good idea to direct a high pressure spray at them just in example this damages the seal between the glass and the panels.

Merely water pressure level from a hose removes bird poo, provided y'all are patient. The trick is to hose the panel downwardly and then come up back 5-10 minutes later later on the h2o has had a adventure to soften the poop and spray it once more. If it doesn't come off requite it some other v-ten minutes and effort again. By this point all or most of it should be gone.

If you tin can physically reach your solar panels you tin can put a wet textile over the bird poo and let it soak for a while. After about 10 minutes the bird poo should be set to come off with just a little water pressure and no need for rubbing which can cause scratches.

Detergents And Cleaners

Water alone gets virtually grime off panels, merely using mild detergent is fine. Dish washing detergent will exercise, merely profoundly dilute it earlier use. While concentrated detergent shouldn't do much damage to glass it may not all wash abroad and the balance of the product used to clean your panels will brand them muddied.

Always thoroughly rinse solar panels after using dish washing detergent. This is because it contains table salt that will contribute to corrosion if allowed to stay on panels. Particularly if they aren't corrosion resistant.

At that place are cleaning products for spraying on drinking glass and and then washing off and they should exist okay to use. But avoid whatsoever products that require rubbing with a fabric. They can cause scratching and require a lot of work for very niggling gain.

Cleaning Solar Panels And Water Tanks

If the gutter below your solar panels leads to a water tank, then anything you wash off those panels will end up in it. This includes detergent. If yous would rather not have soap suds in your h2o tank so simply use water to clean your panels. If you don't like the idea of washing dust and bird poop into your h2o tank, don't feel bad. The pelting washes it in there anyhow when y'all're not looking.

Beware Of Serpent Oil

In that location are solar panel sprays that claim to assist panels clean themselves, but I don't find them convincing. I have an advertising in front end of me for one that contains more lies than my first two marriages. Their production may piece of work just fine. But there is no way I am going to trust a company with less credibility than a paper submarine.

As my close friend Winston Churchill said to me afterwards I single handedly defeated Hitler, "A adept product does not need to be attended by a babysitter of lies."

I say stay away from these products. At to the lowest degree until they prove large calibration solar farms fixated on the bottom line actually use them. And also make certain the cost is low enough to make it worthwhile. And so tell them to go jump anyway. This article is for people who want to clean solar panels, not allow some magical elixir practice it.

Cleaning Panels – Uneconomic, Just Makes You Feel Skillful Within

Because information technology may only improve average output past a couple of percent, cleaning solar panels isn't really worth the effort if it requires you to exercise anything more than than spray them with a hose from the ground. So I don't recommend climbing upwardly ladders or clambering on roofs to clean them. It is simply not worth the risk.

But if you insist on striving to attain great heights, such as those at the top of a ladder or on a roof, delight exist careful and try not to lose an argument with gravity.
