The Solar Ratings & Certification Organization (SRCC) is an independent ratings organization for solar systems and is widely recognized as the official standard in the field. The SRCC rates thermal performance of individual solar collectors, as well as, complete functional systems. Many state and utility rebate programs require SRCC ratings for products to qualify and system performance can be compared to others in the field using the product directory.
The Florida Solar Energy Center (FSEC) is the primary testing lab that performs SRCC ratings. In addition to testing solar thermal systems, FSEC also has their own ratings system that is widely adopted in both Florida and the Caribbean. FSEC is also engaged in a wide range of energy efficient and renewable technologies ranging from photovoltaics to reflective roofs.
The Uniform Plumbing Code, which is maintained by IAPMO governs the way plumbing systems may be constructed in the Western United States. Solar systems are often covered under IAPMO regulations, and an independent Uniform Solar Energy Code has been developed explicitly for the design and installation of solar thermal systems. We offer only IAPMO code compliant listed solar thermal collectors.
The National Renewable Energy Laboratory (NREL) is the central government lab responsible for renewable energy development. In addition to physical testing and development of renewable systems, NREL publishes some of the most comprehensive weather data sets used for estimating system performance. Typical Meteorological Year weather data known as TMY2 is often used in the solar thermal field to size solar thermal systems.
The Solar Energy Laboratory at the University of Wisconsin is one of the oldest labs in the nation dedicated to the study of solar thermal systems. Many industry standard modeling tools such as F-chart and TRNSYS were developed at the Solar Energy Laboratory and their website contains information about these tools.
