Algae on my panels
« on: February 12, 2018, 02:39:06 am »
Algae on my panels ... sounds like a bad song is !

It's been so horribly wet and cool this year that my solar panels are starting to develop a covering of green algae .
 I gave them a clean as best I could using  one of the 5 mtr window cleaning sets ( eBay rubbish )  lashed to another one & could still barely manage to reach the top of the panels on the bungalow roof from the ground ( 9 mtrs approx ) .

One damp & drizzly day  I dipped the cleaning head toweling in neat car screen wash and after some hard work the algae started to disappear . At the end of it all I gave the panels a hosepipe rinsing off and that was it . Three months later it's back with a vengeance .

 We got a shock when the last FIT payment arrived for the period  beginning of Nov to end of Jan £ 40 ... Waaah . it's the lowest we've had  :'(

 What are you  guys and gals using to keep your panels clean ?

I have no idea how well it actually works but the old fasioned trick for keeping moss off roofs was a copper strip along the ridge for copper salts when it rains.

I have no personal experience of solar panel maintenance, but is there something peculiar about your situation/installation cloddopper I wonder?:  I frequently drive by acres upon acres of solar fields ( :( ) and have yet to notice a single maintenance gang out cleaning!
Have you asked the installers/manufacturers about the problem and solutions? 
As a throw-away thought - what about washing-off with a hydrophobic car polish product to add a film over the panels' glass?  (Such car products must surely be 'gentle' on all sorts of materials - silicon or rubber seals etc.  Whether such products really work to help keep surfaces clean, or whether just hype, is another matter!)
