List of products by brand JA Solar

Ja Solar is one of the largest solar companies in the world. With headquarters in China and more than 20 subsidiaries around the world. Ja Solar has been listed for several consecutive years in the Fortune China 500 and in the Global Top 500 of New Energy Companies.

Ja Solar was founded in 2005 as a company that develops and produces products from silicon wafers, solar cells and photovoltaic modules; to photovoltaic power plants. Since then, Ja Solar has been one of the fastest growing companies. Ja Solar has achieved a vertically integrated supply chain, from wafer and ingot production to the assembly of photovoltaic modules. With continuous technological innovation, competitive pricing and a consolidated global sales and service network, Ja Solar is highly valued by customers around the world.

With twelve manufacturing bases in the world, Ja Solar has been for more than a decade a benchmark in the manufacture of solar panels. With a team of more than 29,000 employees (2021) and more than 33,000 customers around the world (2019), Ja Solar has been able to remain one of the leaders in the solar panel market thanks to its constant innovation and cost reduction.

Its main innovations in the field of solar panels are the implementation of PERC technology in its panels. Its 60- and 72-cell panels use Half Cut technology for both monofacial and bifacial panels.

The PERC technology, which is not only exclusive to Ja Solar, consists in the incorporation of an aluminum surface treatment in the back of the solar cell that is responsible for capturing the part of the bluest light spectrum that has not been captured by the front of the cell to reflect it and return it to it, thus achieving an extra solar generation. Therefore, PERC technology increases the efficiency of solar panels. Ja Solar has additionally made PERC technology applicable to bifacial solar panels.

Ja Solar's technology has achieved panels with an efficiency of 22%; with higher power, safer and more stable generation, lower temperature coefficient and lower shading effect.

Ja Solar's non-exclusive split cell technology increases the overall efficiency of the solar panel by approximately 2% through the reduction of electrical resistance of the conductors. As each cell is smaller, the thickness of the conductor can be smaller thus reducing heat losses.

Additionally, split cells reduce the size of hot spots on solar panels, thus minimizing energy losses. This technology has an extra effect that is the best operation and performance in situations of partial shading.

Within the range of Ja Solar products, if we look at the most suitable for residential and / or commercial self-consumption installations, we find the Deep Blue series.

The Deep Blue series of Ja Solar is the most powerful series of the Chinese manufacturer with solar panels ranging between 400W and 580W. The maximum voltage of these solar panels is 51.3V which makes it a very good option for commercial and industrial solar installations of medium size. The Ja Solar Deep Blue panels have half-cell technology with 144 cells either polycrystalline or monocrystalline, providing this series with efficiencies superior to others on the market. Deep Blue panels such as 450W would be considered high efficiency reaching solar panel efficiencies above 20%.

Ja Solar is undoubtedly a market leader with innovative, high-quality products and always at a competitive price. Whether for your self-consumption installation for your home or your business, Ja Solar products are always a good choice with 12 years of product warranty and 25 years of production warranty.
