funny thing is when we work on solar farms along side the quialfied people that look after them they don't wear any of this rubbish nor do there wear just rubber wellies , all sites we have if you not in steel caps your not on site along with hi vis ect ect
theres so much bull about solar panels and cleaning them you could write a book about it , if you scared about cleaning a ray of solar panels then fully cover any one panel on the ray and it will pull the power down so it wont kill you , its the quickest and simplest way to do it , this is straight out the mouth of the head tec guy we work for and he looks after 73 sites
there no way of stopping a panel from make energy unless its dark , even if there not hooked up to the mians or a full string there still making energy , you just need to use your head , cracked or missed up units need to be left alone
