SPF Testing – Collectors
Thermal solar collectors are characterized by their performance, lifetime and safety. For these measurements and tests, several solar trackers, a solar simulator and many other test stands are available. With these, all standard tests are carried out and, of course, individually adapted test series for specific questions are also possible.
Testing and Certification
SPF Testing is one of the leading testing laboratories for the European Solar Keymark certificate and performs all measurements and tests according to the international standards ISO 9806 and EN 12975. Other certifications, such as the American ICC-SRCC label, are possible.
Development and Research
The facilities and expertise of the test laboratory are of course also available for research and development projects. We support you in product development, problem solving and are partners in research projects with trade, industry and universities.
