Quality Assurance

Solar panel warranties and service life expectations have steadily risen from 5 years in the 1980s to the current 25-year standard. Industry experience has taught us that while this level of quality and durability is attainable it is not a given; this level of performance can only be achieved by applying appropriate due diligence through rigorous quality assurance practices. By combining best practices from the European and North American solar industries along with our team’s years of evaluating panel     aging behavior, PVEL developed three project level quality assurance programs to mitigate your technology risk; Lot Acceptance Testing, Latent Defect Screening, and Ongoing Degradation Testing.
