Ginlong Solis vs JA Solar - solar panel manufacturer comparison

Ginlong Solis and JA Solar are both Chinese solar energy companies founded in 2005 and listed on the Shenzhen Stock Exchange (SZSE), both holding Tier 1 bankable status - but a head-to-head comparison must account for one fundamental distinction: these companies operate in different product segments. Ginlong Solis is a solar inverter manufacturer, not a panel producer, with no solar modules in its portfolio. With over 4,500 employees - including 800+ in R&D - Solis ranks as the third-largest solar inverter manufacturer globally, with cumulative inverter shipments surpassing 100 GW and over 80 GW of systems installed worldwide. JA Solar, by contrast, is one of the world's largest solar module manufacturers, employing over 37,000 people and reporting production capacity exceeding 100 GW per year. Its panel portfolio spans 524 models reaching up to 740 Wp, with peak efficiency of 24.4% and an average efficiency of approximately 20.9% across the range.

In terms of technology, JA Solar's portfolio is led by PERC cells (over 52% of models), complemented by next-generation TOPCon modules in the DeepBlue 4.0 Pro series. Roughly 44% of its lineup is bifacial, and the average temperature coefficient of -0.32%/°C per degree Celsius is well suited to temperate climates. JA Solar earned PVEL Top Performer status for the tenth consecutive time in 2025 and ranked second in SolarReviews' Best Solar Brands of 2025, reinforcing its reputation for module reliability. Solis inverters, meanwhile, are noted for a 99.73% reliability rate, support for multiple third-party battery brands in hybrid configurations, and standard warranties of 10 years extendable to 20 - making them a value-oriented choice for residential and commercial C&I installations across Europe.

For international buyers specifying a complete solar system, Ginlong Solis and JA Solar are better viewed as complementary partners than rivals - one supplying conversion equipment, the other the generation modules. Buyers seeking a reliable, cost-competitive inverter with broad battery compatibility will find Solis a strong candidate, while those sourcing high-output modules with a long track record of independent quality testing should consider JA Solar's extensive portfolio, particularly its TOPCon and high-wattage bifacial offerings for utility-scale or commercial projects.
