The good old British winter time brings snow particularly in the North of England. Solar panel arrays build up snow and freeze on the panels. There have been instances of the icy snow sliding off the panels and damaging cars parked on driveways. More importantly you could have children playing outside when this happens.
Solar Safeguard (NW) ltd offer a solution to this by fitting a snow guard. Fitting this system will protect anything or anyone from a cascade of ice and snow if this were to happen.
Don’t wait till winter to have it done.
