The new module has a power of up to 650 W and weighs 29.6 kg. It uses JA Solar’s patented anti-dust frame technology, which is said to improve drainage and decontamination performance, reducing dust accumulation and avoiding hotspot issues.
Chinese solar module manufacturer JA Solar presented a new dust-resistant TOPCon solar module at the SNEC fair, which took place last week in Shanghai, China.
“It is specifically designed to meet the unique demands of rooftop scenarios,” a company spokesperson said pv magazine. “This module is lightweight, very reliable and easy to maintain.”
The most important feature of the new single glazing product is a special feature encapsulation n-type paste. “Using advanced encapsulation and specialized n-type paste, this module effectively prevents water vapor ingress and corrosion,” the spokesperson continued. “It has excelled in multiple enhanced IEC reliability tests, with a degradation rate significantly below IEC standards.”
The panel also features JA Solar’s patented anti-dust frame technology, which is said to improve drainage and decontamination performance, significantly reducing dust accumulation and avoiding hotspot issues. “This results in lower maintenance costs,” the spokesperson said.
The module measures 2,465 mm x 1,134 mm x 30 mm and weighs 29.6 kg. It has a power of 650 W and an energy conversion efficiency of 23.3%. The no-load voltage is 53.27 V and the short-circuit current is 15.41 A. The temperature coefficient is -0.29%/C.
“Data shows that compared to conventional non-dust-proof TOPCon modules, this module achieves 3.5-4.5% more yield,” the spokesperson added. “From our customer’s perspective, the lower maintenance frequency and costs are also significant benefits.”
