FREMONT, California, June 3, 2019 /PRNewswire/ -- Continuing to support solar panel manufacturers in the development of high-quality products, and solar project developers, financiers, and end-users who seek high-quality panels, Renewable Energy Test Center (RETC) has released its first annual PV Module Index. The report is the first comprehensive assessment of top-performing modules that are tested for reliability, performance, and quality across 18 different indicators. Within the data, two manufacturers are recognized for demonstrating high achievement across indicators in all three categories.
"RETC is releasing this index to help the entire solar industry better evaluate modules based on important attributes beyond efficiency and cost," said Cherif Kedir, RETC President and Chief Executive Officer. "It's worth noting that high achieving quality module manufacturers put their products through an exhaustive set of accelerated reliability tests, while other manufacturers choose to select only a few of the tests to characterize their products. We congratulate the high achievers in each of the categories, and look forward to working with all manufacturers to continue to demonstrate their product excellence."
In 2018, RETC tested more than 2,500 individual modules, from more than 150 different module families, made by 46 different suppliers. While RETC evaluated modules on 18 different criteria, the report focuses on eight important criteria that best represent the three categories of reliability, performance, and quality. The report calls out high achieving modules that demonstrated results at the top of the distribution for each of the eight criteria.
"As the industry has matured, solar professionals may want to focus on the cost per watt, but modules with the lowest price are not always top values in performance, quality or reliability," said Chris Beitel, Head of Business Development at RETC. "By focusing on all three categories, module manufacturers can have confidence their products are well-equipped to perform across the board, while downstream players can feel assured the products they are selecting are engineered to deliver as expected."
The report provides data showing test results for modules that achieved results at the top of the distribution. The paper also shares data on new technologies, such as bifacial and PERC, more recent entrants to manufacturing, and the differences between laboratory testing and real-world field performance and reliability testing.
Additional tests that are discussed in the report that covers reliability include Humidity Freeze, Thermal Cycling and Ultraviolet Exposure. In performance, other tests include Incidence Angle Modifiers and Light and Elevated Temperature Degradation. Finally, in the area of quality, additional tests in the report cover Engineering Changes, Bill of Material Changes, Randomized Sampling, Factory Audits, and Factory Inspections.
The tests were completed at sites in Fremont, California; Pahrump, Nevada; Los Andes, Chile and in Cagayan de Oro City, in the Philippines.
