Featuring Advanced German Technologies
Appealing Design -
The SOL 25 Plus has less depth than other panels, making it visually less obtrusive and compatible with existing architectural designs.
Maximum Efficiencies - The SOL 25 Plus is a real workhorse. The net absorber surface of almost 27 sq feet results in a maximum output of 2000 watts per panel. The SOL 25 S also offers features such as a selective absorber coating, glass with the highest possible light transfer coefficient, and a very effective insulation around the absorber. The heat transfer pipes are copper.
Installation Time is Minimized - The large panel size and the availability of a full complement of custom designed installation accessories minimizes the installation costs.
