Key Insights
JA Solar's n-type DeepBlue 4.0 Pro module earned the 'Overall Highest Achiever' award from RETC for the sixth consecutive year, demonstrating consistent high performance.
The module excelled in 12 test categories, including damp heat, PID, and UVID, underscoring its long-term durability and power output under extreme conditions.
Only 13% of all products tested by RETC met the rigorous standards for this award, highlighting the DeepBlue 4.0 Pro's exceptional quality and reliability.
This repeated recognition reinforces JA Solar's market leadership and strengthens customer and investor confidence in its advanced photovoltaic technology.
JA Solar has once again secured the coveted ‘Overall Highest Achiever’ recognition from the U.S.-based Renewable Energy Test Center (RETC) in its 2025 PV Module Index Report. This marks the sixth consecutive year the Chinese solar giant has received this prestigious award, underscoring the consistent high performance and reliability of its flagship n-type DeepBlue 4.0 Pro module under rigorous testing conditions. This repeated accolade reinforces JA Solar's position as a leader in advanced photovoltaic technology, a critical factor for investors and project developers seeking durable and efficient solar solutions.
RETC’s ‘Overall Highest Achiever’ award is granted exclusively to modules demonstrating exceptional and consistent performance across key indicators of quality, performance, and reliability. This year, only 13% of all products subjected to RETC’s comprehensive testing regimen met the stringent criteria required for this distinction, highlighting the exclusivity and technical superiority of the DeepBlue 4.0 Pro module. The module particularly excelled in 12 individual test categories, with notable performance in damp heat (DH), potential-induced degradation (PID), and ultraviolet-induced degradation (UVID) tests, alongside superior efficiency metrics. These results are crucial as they directly correlate to the module's long-term durability and power output, especially when deployed in diverse and challenging environmental conditions.
The DeepBlue 4.0 Pro’s robust performance in tests like DH and PID is particularly significant for project developers, as these factors directly influence a module's degradation rate and overall energy yield over its operational lifespan. High resistance to UVID also ensures sustained performance in regions with intense solar radiation. This comprehensive strength in critical performance parameters translates into enhanced bankability for solar projects utilizing these modules, offering greater assurance to financiers and asset owners regarding their return on investment.
“Our long-standing commitment to delivering high-quality, high-reliability modules stems from a focus on creating real value for our customers,” commented Aiqing Yang, Executive President at JA Solar. “These repeated recognitions from authoritative bodies such as RETC affirm the strength of our technology and reinforce customer trust in our products worldwide.”
This consistent third-party validation from an independent body like RETC is a testament to JA Solar’s robust research and development capabilities and its stringent quality control processes. In a rapidly evolving global solar market, where the demand for higher efficiency and greater durability is paramount, such achievements set a benchmark for the industry. The DeepBlue 4.0 Pro module's success reflects a broader industry trend towards n-type technology, which offers superior performance characteristics, including lower degradation rates and improved low-light performance, making it increasingly attractive for utility-scale and distributed generation projects globally.
