Stiebel Eltron SOL 27 Premium is a highly efficient solar thermal collector, among the top 10 collectors measured for output by the SRCC. The net absorber surface of over 25 square feet results in a maximum output of 31,300 btu/day per panel (SRCC clear day rating). The SOL 27 Premium features a highly selective absorber coating, low-iron, tempered solar glazing, and very effective insulation around the absorber plate. The internal fluid tubes are copper and the absorber plate is aluminum. The low 3˝ profile of the SOL 27 makes it visually less obtrusive and able to accommodate a variety of architectural and engineering needs.
SOL 27 Premium collectors are available in both Standard (Vertical) and Wide (Horizontal) configurations. Manufacturing in the US for our collectors and racking systems also means we can custom-anodize collector frames and racks to meet specific architectural color requirements.
