Recently, the DAS Solar N-type bifacial double glass module demonstrated exceptional product performance through a series of rigorous tests in PV Evolution Labs (PVEL)'s Product Quality Program (PQP).

As a globally recognized, independent third-party testing laboratory, PVEL conducts comprehensive evaluations of PV module designs through its PQP testing, assessing environmental sensitivities and degradation mechanisms. The PQP testing includes a broad spectrum of assessments, such as thermal cycling, damp heat, potential-induced degradation, light-induced degradation, light and elevated temperature-induced degradation, and mechanical stress sequences. The DAS Solar N-type modules exhibited outstanding performance across all stringent tests, demonstrating module’s stability and reliability under various extreme environmental conditions.

As far as PV plants are concerned, module stability directly impacts their performance and lifespan. As a result of continuous technological innovation, DAS Solar has been ensuring efficient operation of modules under a wide variety of environmental conditions in recent years, improving the stability and reliability of its products. The performance of DAS Solar N-type modules remained significantly unaffected during the recent PQP testing after they were subjected to 600 thermal cycling stress at temperatures ranging from -40°C to 85°C and 2000 hours of Damp Heat testing at 85°C and 85% RH. The module materials and structure demonstrate their resilience in extreme cold, extreme heat, and humid conditions.

There is a particular need for wind-resistant PV modules in areas with abundant wind resources. In mechanical load, DAS Solar N-type modules demonstrated excellent structural integrity and stable power output, demonstrating superior wind resistance. Even under strong wind assaults, DAS Solar N-type modules can ensure safe and continuous power supply. In areas with significant wind forces, this advantage will facilitate the application of DAS Solar's PV modules in coastal and high-altitude regions.

DAS Solar N-type modules have also demonstrated excellent heat resistance, light resistance, and long-term stability in recent potential-induced degradation (PID) and light and elevated temperature-induced degradation (LETID) tests. Its core strengths in technological innovation, material selection, structural design, and manufacturing processes are highlighted in these results. In addition, providing customers with highly reliable product services over the module's entire lifecycle, DAS Solar offers a 15-year material warranty and a 30-year power output warranty, ensuring higher electricity generation and greater returns over the module's entire lifecycle.

Throughout the years, DAS Solar has been researching and developing N-type technology to cater to various extreme environments, such as deserts, mountains, seas, and rainforests. As a leading company in N-type technology, the outstanding performance in the PVEL tests serves as a powerful testament to DAS Solar's technological innovation and quality commitment. By continuously testing and certifying its photovoltaic products, DAS Solar will ensure that its research and development technology and product performance remain on par with industry standards, providing superior photovoltaic products to global customers.
