Evacuated Tubes

Features & Benefits

The Joule Acapella Solar system’s unique tube design ensures
a very high zero-loss collector efficiency figure of
85% based on the absorber. The unique method of fixing
the tubes into the collector results in a significantly lower
heat loss coefficient of 1.529w/m²K. The collectors easy to
install frame ensures that the collector is securely fixed and
mounted onto the roof every time.

• We are so confident of the quality of our solar collectors
that we have tested our collectors to double and sometimes
four times the requirements of EN12975:1-2 and they are Solar
Keymark.

• The high-efficiency collectors are further tested to determine
the maximum positive and negative loading force
that the collectors can resist.

• The collectors have been tested to determine their impact
resistance using a steal and iceball methods.
