A warning sign has been raised in the solar energy sector: around 83% of photovoltaic module manufacturers have shown at least one failure in the rigorous laboratory tests of the PQP (Product Qualification Program), conducted by Kiwa PVEL – one of the main global references in solar performance assessment.
The program's most recent report, released this Wednesday (4), points to a 66% increase in the number of failures found compared to the previous edition, setting a historic record since the study was created. The PQP consists of a series of reliability and performance tests that simulate different environmental and mechanical conditions to which photovoltaic modules may be subjected on a daily basis.
The tests include exposure to extreme temperatures, high humidity, mechanical stress, hail impacts and intense ultraviolet radiation. In this year's edition, nine of the 50 manufacturers analyzed had performances considered “Top Performer” in all seven categories (tests performed) of the study. Find out more by clicking here.
For Kiwa PVEL, the rapid pace of technological innovation in the solar energy makes it even more essential that distributors, integrators and consumers carefully evaluate products before purchasing.
The institute warns that not all modules available on the market have the same quality standard and reinforces the importance of companies and professionals in the sector opting for technologies that meet reliability criteria, avoiding long-term losses.
This year's report marks the 11th annual cycle of the PQP, consolidating itself as one of the main technical guides for professionals and companies working in the selection and specification of solar modules around the world.
