    One of my customers is a solar panel installer, so I thought I'd ask his advice on cleaning them etc. He told me that the panels need switching off in 2 places and tested before and after the cleans to make sure they are working correctly before and after the job. Or the customer could put the onus on you should there be a fault occur. Bearing in mind the price of replacing a faulty panel and the price of erecting scaffolding is very costly. What precautions do you take if any and do you any of you follow this route bearing in mind to have a qualified tester present would be approximately £50.

    You can't turn them off is the correct answer as each panel which makes up an array with still continue to produce a direct current output in daylight.

    Load of ******** i reckon, what happens when it rains? Does the owner have to switch them off then get them tested when the sun comes back out?
    What about torrential rain? Do you have to scaffold, and remove them and put em in the garage?
    As an installer i would suggest he is spouting what his bosses say i.e. Earn money for old rope, blag the customer/uneducated
    Just my opinion bud

    I'm pretty sure no insurance company would pay out should you not take the right path. And I'm thinking the risk outweighs the possible gain.

  8. You can't turn off the dc open circuit. But on most (or all the ones I've come across) grid tie inverters, there is an ac trip switch. Whether or not you'll benefit from disconnecting from the grid is another issue.

    Solar Steve is the man for cleaning solar panels but he never shares any of his knowledge so he's pretty useless to us in my honest opinion
