Solar Product Certification 

IAPMO R&T has been certifying solar thermal products, both collectors and systems, since the technology enjoyed its first heyday in the mid-1970s. With the demand for solar certification skyrocketing once again amidst the global push for environmental sustainability, IAPMO R&T remains a manufacturer’s best ally in showing compliance to the required standards, both in the United States and Canada.

 For speed to market, credibility in name and mark of conformity, as well as a complete certification program to all applicable North American codes and standards recognized by Federal and State agencies, IAPMO R&T is the best choice for your solar heating products.
