Solar PV in Scotland? Yes it works, solar Photovoltaic actually only needs daylight to work. Burning sunshine obviously works better and you will see more benefit in the height of summer but that does not mean it is redundant in winter, as long as it is in the light, not in shade, it will generate electricity for you.
As you can see from the photos we are not afraid of a bit of snow, even on the roof during installation, as long as we have our harnesses we will go anywhere. A nice hot cuppa was needed after this installation though!
