JA Solar VSUN is a PV module fit for both residential and commercial applications. JA Solar engineers made the Deep Blue series durable and efficient while minimizing the amount of useful space required for their operation. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.
Another advantage is the half-cut cell technology. VSUN has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. As a result, the panel achieves an impressive efficiency of 20.9%. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. JA Solar paid as much attention to durability as they did to performance. VSUN is guaranteed to retain at least 84.95% of output after 30 years. Product warranty for this panel lasts 12 years.

Higher efficiency of up to 20.9%
VSUN guarantees the highest power output. PERC technology and potent antireflective coating result in 20.9% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.
The heat is less of a problem with this module: with one of the industry's lowest temperature coefficients, VSUN loses just 0.35% of efficiency for every 1.8°F over 77°F.
Quality and reliability
VSUN receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. JA Solar is dedicated to quality, safety and reliability to ensure you get the very best.
Low degradation for increased lifespan
The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 30th year will not surpass 0.45%. After 30 years, the module will still produce more than 84.95% of its initial output.
Improved frame design
VSUN design makes it suitable for both residential and business rooftops. The use of a strong 1.37" frame composed of anodized aluminum boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 2400 Pa, guaranteeing that your system will resist even the fiercest winds.
