Alaskan here; it doesn’t work so hot in the winter months. Even if they are kept clear by maintenance workers (not that hard or expensive to hire someone to clear snow from a panel) the sun’s azimuth is so low in the winter that there is hardly any energy produced.

Small correction: you mean altitude, not azimuth. Altitude is how far you need to tilt your head vertically to look at an object. Azimuth is the compass direction.
