The auroTHERM exclusive vacuum tube solar collector have been designed to give maximum energy absorption and are easy to install in various applications. As the collectors work on diffused solar radiation as well as direct sunlight, they will even generate small amounts of energy on partially cloudy days. Multiple panels can easily be fitted together as required for larger systems.
