About Collector Days

Not all collector days are the same.

It is important to note that the current and outdated testing methods do not do our collectors justice!

For our tubes, there does not need to be a full sun hour or a "90 degree angle of incidence".

These collectors make maximum use of the sun of sun all day. Low slope roofs – no problem, steep pitches – no problem, flat roofs – no problem,wall mounts – no problem. In fact, our collectors are the most aesthetically pleasing and easily installed evacuated tube collectors on the market. The absorber surface is 360 degrees, allowing our collectors to capture energy from all angles. They can even capture energy from the backside. 

Another key element to our unique design is that the majority of energy transfer of energy to the heat transfer fluid occurs within the vacuum itself. Other designs do this same process outside of the vacuum, resulting in increased heat loss.  pURe evacuated tube collectors are simply superior in real world applications
