 Maximum Efficiencies.
The SOL 25 S 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 internal water passages are copper.
Installation Time is Minimized.
The large panel size and the availability of a full
complement of custom designed instal-lation accessories minimizes
the installation costs.
Lasting and Reliable Energy Saving
Investments.
Stiebel Eltron uses only the most durable materials on
these panels. The SOL 25 S is the culmination of 25 years of
experience in the solar business.
