Evacuated Tube Solar Collectors are extremely efficient and cost-effective particularly in colder climates where other Solar Collectors suffer from limited performance and other problems due to their lack of freeze protection. Evacuated Tube Collectors however are extremely freeze protected leading to efficiencies of over 70% even in freezing temperatures. The unique design and collection properties of these Evacuated Tubes make them exceedingly efficient even in low-light conditions which is also a definite advantage in winter.
SunMaxx Evacuated Tube Solar Collectors are the most affordable cost-effective solar collectors available on the market today.
