Certification & Ratings Organizations
Solar Ratings & Certification Organization (SRCC) -
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.
Florida Solar Energy Center
(FSEC) -
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.

Industry Association of Plumbing & Mechanical Officials (IAPMO) -
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.  SunEarth solar
thermal collectors are listed as compliant with IAPMO codes.

American Society of Heating, Refrigeration and Air-Conditioning Engineers
ASHRAE is the leading trade organization for HVAC (Heating Ventilation & Air-Conditioning)
professionals in the world.  For anything from residences to skyscrapers, ASHRAE has
developed standards for it and you'll find equipment suppliers serving that broad range at
their annual trade fair.  ASHRAE is also responsible for standard 93-1986, which is the
standard used by the SRCC and FSEC in testing solar thermal collectors.

American Society of Mechanical Engineers (ASME) -
A leading industry organization for mechanical and thermal systems engineers, ASME is a
good clearinghouse of information and produces the ASME Journal of Solar Energy, which
includes research on solar thermal systems and heat transfer.

Educational & Informational Sites
National Renewable Energy Laboratory (NREL) -
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
University of Wisconsin Solar Energy Laboratory (SEL) -
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 & their
website contains information about these tools.
