Solar Thermal Performance Comparison:
Akotec versus Sunrain and most other Solar Thermal Tube Collectors
You have very likely previously heard the terminology that “not all things are created equal”.
This is especially true when it comes to comparing Solar Thermal Collector Tubes.
A large majority of Solar Collector Tubes are made in China. They may look similar and claim to provide the same results however, under what weather or operating conditions? How fdo they compare with overall performance and longevity? Dollar to Value?
Below we have provided some data and links to assist you with your analysis.
Place of Manufacture:
Akotec: Germany, Sunrain China
Warranty:
Akotec has a 20 year tube performance warranty, 10 years on the collectors
Sunrain 10 years manufacturer defect
Overheat Protection:
Akotec, has a built-in overheat protection that limits the collector to 100C. This means that if it stagnates for long periods (in the summer, due to power outage or mechanical failure) it won’t damage the system.
Sunrain, nothing
Materials:
Akotec is completely made from anodized aluminum where as the Chinese collectors (like Sunrain) are made from powder coated steel which will eventually rust.
Performance:
ICC-SRCC https://solar-rating.org/ is the authority for Solar Thermal Heating and Cooling products.
