solar panels around skylights

StuSid | Posted in General Questions on

I am installing a grid tied solar system on a cape style house on the coast of Maine with the help of a local electrician. I will be asking the electrician this same advice but wanted to throw it out into the building crowd as well.

Does anyone have any recommendations or insight for how far solar panels should be from skylights? The PV panels are being installed over an asphalt roof, 14/12 pitch. My concern is snow sliding down off the top row of panels onto the top lip of the skylight and creating a damn. Would it be best to leave a larger or smaller space between panels and skylight? Obviously this is south facing and I have never had any issues with dams in the past 10 years.   Thanks in advance for any insights.

    Are they conventional skylights (i.e., Velux or similar)? If so, with a 14:12 slope, I wouldn't worry--there will be enough heat loss around the skylights to melt any snow accumulation.

    THanks Michael,

    Yes, Velux skylights. I won't worry!
