Caleffi Hydronic Solutions says its NAS3 Series solar water heating systems, which are used in residential and small commercial building applications, are now OG-300 certified by the Solar Rating and Certification Corp. (SRCC).
All 84 models of the solar system packages are approved and are now eligible for government, utility and local financial incentives requiring OG-300 to qualify. As of September, over 20 states offered incentives requiring the SRCC's OG-300 certification, according to Caleffi.
