Viessmann received OG-300 System Certification from the Solar Rating and Certification Corporation for seven new residential system packages. The packages feature one to three Vitosol 200-F flat plate solar collectors as well as single-coil Viessmann or Rheem Solaraide storage tanks. 

OG-300 System Certification is required by a number of U.S. state and federal incentive programs and will provide access to additional government funds towards the investment of a residential solar system.
