On Roof

Features & Benefits

The sleek Joule Navitas On-roof solar system is designed
and manufactured to work in Northern European climates.
The collector’s black finish makes it an attractive addition
to any roof. The unique patented ventilation system ensures
the collector provides maximum output while reducing heat
loss from inside the collector.

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

• The high-efficiency collectors are further tested to determine
their maximum impact force resistance levels and
the maximum positive and negative loading force that
the collectors can resist.
• The Joule Navitas range offers both vertical and horizontal

• All testings have been carried out by the Building Research
Establishment (BRE) in Watford.
