Applying a water repellent coating to your panels ???

[finchy]

To be honest an annual inspection can not harm if done right and I would recommend it! A lot of customer ask about it and yes they are self cleaning but I have read loads about it on American websites, it all depends on location. Pollution creates a film on the panels, let alone a large dollop of birds crap. At the end of the day customers want to ensure maximum performance, hence a little clean of the panels check on inverter down load and analysis of outputs can't be bad.

We only did a few sharp installs before i saw the light as they say , and the only 3 that i have seen problems with so far have been all sharp to be honest so i really do hope it is the exception !?

Yes agree we saw the light with Sharps about 6 months ago and only fitted some recently as that's all we could get. Haven't fitted any at 15 degree but I will certainly post if we have any issues with the in the future.

There are a few options out there for auto cleaning panels, thought you might like the above links. Doesn't really apply to this thread per se but does demonstrate the fact that there does seem to be a demand for cleaning panels....regardless of whether they are supposedly "self-cleaning" or not....

Not sure about walking on the boards on the pv panels, 3/4 blokes and the 'CHERRY' picker not going to be cheap! The scheletter system looks better !
