Solar panel cleaning

[Shaun1977]

Has anyone got any links that could be put to leaflets explaining how the panels lose efficiency when thy dirty

Ive had 3 since I started, better than nothing I suppose. I get a lot of gutter and conservatory roof cleans.

I hardly get any of these type of cleans lol

Advertisement is the key, also do you have gutter cleaning in your services in gogle+ I rank on the 1st page for gutter cleaning in fife with this, same with gumtree

if you look at my site it will tell you when to get them clean

Mark i been on your website a lot of times.... before i startted window cleaning /emoticons/tongue.png i used to check a lot of window cleaning websites out .. and i always used to get on yours lol

I like it... how it explains everything

very good /emoticons/tongue.png

its not all about them being dirty and loosing the ammont of power that is being produced.

one main reason for cleaning them is to keep the hotspots off them to stop them burning out.

Hot-spot heating occurs when there is one low current solar cell in a string of at least several high short-circuit current solar cells, as shown in the figure below.

One shaded cell in a string reduces the current through the good cells, causing the good cells to produce higher voltages that can often reverse bias the bad cell.

If the operating current of the overall series string approaches the short-circuit current of the "bad" cell, the overall current becomes limited by the bad cell. The extra current produced by the good cells then forward biases the good solar cells. If the series string is short circuited, then the forward bias across all of these cells reverse biases the shaded cell. Hot-spot heating occurs when a large number of series connected cells cause a large reverse bias across the shaded cell, leading to large dissipation of power in the poor cell. Essentially the entire generating capacity of all the good cells is dissipated in the poor cell. The enormous power dissipation occurring in a small area results in local overheating, or "hot-spots", which in turn leads to destructive effects, such as cell or glass cracking, melting of solder or degradation of the solar cell.

i have done several solar panel cleans and have about 12 more on my books still to clean. I work along side a solar panel fitting company that has giving me all the details, training on the things to look out for etc on there solar panels,

You can find plenty of info on why to clean solar here: http://www.solar-panel-cleaners.com/why-clean-solar-panels.php

The evidence for the benefits of regular solar cleaning is overwhelming and don't let anyone tell you the rain will clean them either!
