Does solar thermal work in the winter?
Just like solar electric panels, your solar thermal panels will work during the wintertime. They will generate less hot water than in sunnier months, so you may have to use your backup water heater more often during cold weather. Any snow that is accumulated on the panels will typically slide off on its own when the sun comes back out. Solar thermal systems installed in Cambridge will also have freeze protection.
