Cleaning

My roof is colourbond surfmist. A year and a half in and it's a bit grubby round the edges. Could I kill two birdies with one stone and get the solar panels cleaned too? Would there be a special solution that would have to be used on the panels seperately?

I have a massive GUM tree at the back of my place, and with the flowering period just finishing, the solar panels have a sooty film.
I will be up with a bucket and some dish-washing detergent to clean them this weekend.

So, to your question, it's a perfect opportunity..

Once a month (unless there has been recent rain) I get up on the roof and clean my panels. I use just plain water, since the roof is the catchment for the water tanks here. I use a squeegee of the type you might use for cleaning the car windscreen, except that it's on a broom handle to give greater reach.

If you are “getting” somebody in to clean the Colorbond, are they planning to use a high pressure sprayer?

Has anyone had any experience with this?

• Is there any impact on manufacturer’s warranty?
• What about avoiding spraying connectors and DC isolation boxes?
• Are they planning to use detergents that might be harmful to any of the components?
• Does the sprayer heat the water & to what temperature?
• Even if you choose not to get the panels sprayed, are they susceptible to water being sprayed right near them and bouncing up from underneath?

Hopefully none of this matters but I'm just thinking of anything beyond what a heavy down pour would subject them to.

Whatever the answers are, just make sure that they are going to be as careful with your system as you would be especially if they need to get up onto the roof and potentially drag hoses around or wave a spraying boom near it.

Even if they don't use a sprayer, I would guess that if a suitable detergent is used then a rinse with fresh water would be a good idea.

Absolutely, keep them clean. I know of too many people who once the system is installed just ignore it without even periodically checking the power generated. Typically they are the ones who complain the loudest when they find out months down the track that they haven't been getting the performance that they paid for.

As for killing two birdies with one stone, that might bring you bad Karma. You could end up with all of their brothers, sisters, aunts, uncles & cousins flying back and crapping on your panels or you could crack a panel if your stone is too big. :lol:

I guess the other thing to consider is the type of chemical that is used because a percentage of it will drain into the rain water tank. Thanks for all your advice.

Plain old water with a squeegee on a painters extension pole, as that way I can stand back from the panels, and do them in long swipes.

Indeed... in 20 years of cleaning panels, I've never had the need to use anything other than water and a bit of elbow grease ;)

Works better when you link to a png file, rather than the jpg that I put in my sig file !!

Thanks for pointing that one out. :)

Can't use anything other than elbow grease when the run off goes in to your drinking water tanks!

Lol, I like that bit - was just thinking about cleaning my panels as well since I back onto a main road and the panels have a layer of dirt / dust on them.
