JA Solar DeepBlue 3.0 and 4.0 series panels

While perovskite technology stands out as the most efficient among photovoltaic (PV) panels, the prevailing choice in today’s solar panels is monocrystalline. Within the domain of monocrystalline cells, N-type technology is anticipated to become the dominant solution in the market by 2023. With the advent of DeepBlue 4.0, JA Solar has transitioned to N-Type technology following the introduction of DeepBlue 3.0. The remarkable increase in efficiency to 22.4% was achieved through the incorporation of advanced N-type cells and innovative Gapless Flexible Interconnection (GFI) technologies.

This technological leap has propelled module power to an impressive 635W. Leveraging GFI technology, module power can be augmented by over 5 watts, accompanied by an increase in module efficiency by at least 0.2%. Noteworthy enhancements have been made in the degradation factor, with first-year degradation less than 1% and annual degradation over 30 years held below 0.4%. The temperature coefficient has been reduced to -0.30%/°C, showcasing minimal temperature-dependent power loss (ΔPmax/ ΔT). The overall power loss is a mere 2%, significantly surpassing the rigorous IEC standards. Moreover, the Bifacial Benefits have been elevated to an impressive 80%.

Below you will find the main products using all the above-mentioned technologies.
