To identify the best of the best, RETC reviewed and ranked the overall data distributions across three disciplines: quality, performance, and reliability. Backsheet ultraviolet durability Top performers: JA Solar, Longi. The Renewable Energy Test Center (RETC) released its 2023 PV Module Index report, evaluating the reliability, quality, and performance of solar panels. Solar modules are put through a variety of accelerated stress tests to evaluate these parameters. Through comparative test results, project. Only two manufacturers have a single model type listed as a Top Performer in all reliability tests (TC, DH, MSS, HSS, PID, UVID and LID+LETID). See the new Manufacturers page for more. The 2025 PV Module Manufacturing Quality Report by Kiwa PI Berlin provides a deep dive into the current state of global PV manufacturing, highlighting key.
