Where can I find more information on the ratings provided in the OG-100 certificates?

OG-100 certificates contain information geared toward consumers, code officials, incentive program operators and solar system design professionals.

• Consumers: OG-100 ratings can be used to compare the performance of different collectors on a consistent basis to get a true “apples to apples” comparison. This can help select the right product for your application.
• Code Officials: Building codes throughout the US and Canada require that solar thermal collectors comply with industry standards like ICC 901/SRCC 100. A current OG-100 certificate provides proof to code officials that the product has been evaluated to the listed standard by ICC-SRCC staff and meets comprehensive third-party certification program requirements.
• Design Professionals: Designers of solar thermal systems need key performance values for solar thermal collectors. This is used to properly size and configure the system for the intended use. Information like efficiency equations and incident angle modifiers serve as inputs to modeling software to characterize the performance of each collector.
