Wagner Solar says its ECO BASICline range of solar heating systems has received OG-300 certification from the Solar Rating and Certification Corp.
The product line includes five new residential system packages with either 80-gallon or 105-gallon solar storage tanks. The packages feature the EURO C20-AR collector family, which rank among the highest-rated solar thermal flat-plate collectors under OG-100, according to the company.
OG-300 system certification is required by a number of U.S. state and federal incentive programs.
