Product Overview

The Joule Evacuated Tube Solar System’ unique tube design ensures a very high zero-loss collector efficiency figure of 85% based on the absorber. The unique method used by Joule for fixing the evacuated tubes into the collector results in a significantly lower heat loss coefficient of 1.529w/m²K.

The evacuated tube solar systems have an easy to install frame that ensures that the collectors are securely fixed and mounted onto the roof efficiently and correctly every time.

What is a Solar Thermal Panel?

While solar PV panels use the energy from the sun to generate electricity, solar thermal panels use the sun to heat up water. As such, solar PV panels and solar thermals are two very different technologies.

Solar thermal uses free renewable energy from the sun which, just like the solar PV panels, will help you save money and reduce your carbon footprint.
