Why It Works

Our Evacuated-tube collectors convert solar energy to useable energy four to five times more efficiently than other systems.

Ultraviolet and visible light waves are converted to infrared or heat waves on the inner evacuated tubes of the system.  The vacuum between the tubes acts like a thermos, preventing the heat from radiating back out to the environment. Temperatures can reach 470F on the inner evacuated tubes and heat water up to 270F.

Atmospheric conditions, latitude, date, time, inclination angles, temperatures, usage, and working fluids, are all factors that determine solar thermal efficiencies.
