What about cold weather?

Absolutely! During the winter, the sun is at low angles in the sky, the days are extremely short, and the temperatures are often freezing, or barely above. SunMaxx Evacuated Tube Solar Collectors are particularly well suited for these conditions. Their unique 360 degree collection area makes them very good at capturing sunlight at many angles, increasing the period of optimum absorption, and their incredible freeze protection, coupled with a closed-loop glycol system provide adequate freeze protection in even the harshest temperatures.
