Solar Thermal Testing
Solar Thermal Testing Facility
The N.C. Solar Center has over 15 years of experience testing solar collectors and systems. The Center’s engineers have provided performance testing to designers, manufacturers, and distributors of large scale concentrating solar thermal systems, low cost solar air heaters, concentrating PV systems, traditional PV modules, flat plate solar thermal collectors, and evacuated tube solar thermal collectors.

Why is it important?
- Protects consumers by serving as a national standardized method to compare solar equipment.
- Assists solar thermal system designers by providing accurate & dependable ratings of performance.
- Assists policy and planning at the government level by providing a means to manage the quality of an incentive program as well as the basis for setting codes and standards.
- A dependable measure of quality and function makes the solar thermal industry stronger, by providing an unbiased evaluation of a collector’s quality and performance.
How is certification obtained?
- A solar thermal collector manufacturer begins by contacting the Solar Rating and Certification Corporation (SRCC) and submitting an OG-100 application.
- The manufacturer completes and submits the N.C. Solar Center Testing Lab collector testing application. Please call with any questions, we are here to help. 919-513-0418
- The manufacturer signs the university testing service agreement and statement of work , and submits appropriate payment (see pricing on page 3 in statement of work) .
- The testing laboratory works with the manufacturer to randomly select the required collector(s) for testing per SRCC RS-! Random Selection Procedure.
- The manufacturer sends the selected collector(s) to the lab in Raleigh, N.C. for testing.
- The testing laboratory evaluates the quality and performance of the collector by completing the requested tests.
- A final test report is sent to the manufacturer and then to the SRCC for a processing for OG-100 certification.
What is the testing like?
- Testing is a combination of quality and performance tests specified by SRCC Standard 100, which is largely based on ISO 9806 test standards.
- Static Pressure Test
- Thirty-Day Exposure Test
- Thermal Shock/Water Spray Test
- Thermal Shock/Cold Fill Test
- Static Pressure Test
- Collector Time Constant Determination Test
- Post-Exposure Thermal Performance Test
- Incident Angle Modifier Test
