Wagner receives OG-300 certification
Wagner Solar Inc. received the OG-300 certification for five new residential solar system packages with 80 or 150 gal storage tanks. The certification is required by several US incentive programmes in the USA.
The ECO BASICline packages feature the EURO C20-AR collector family. With a Solar Energy Factor (SEF) rating of 21.7 under OG-300, the ECO BASICline is a high performing system under stringent SRCC testing procedures. For comparison: the US Department of Energy considers an SEF between 1 and 3 as typical for solar thermal systems.
