The available data registers zero panels under the Depozit Solar brand, reflecting its role as a reseller of third-party modules from brands such as Jinko Solar and Canadian Solar. It does not hold Tier 1 bankability status and has no disclosed production capacity or founding year in industry databases. JA Solar, by contrast, is one of the world's leading PV manufacturers, founded in China in 2005, with a workforce exceeding 37,000 employees and a production capacity of over 100 GW. The company is listed on the Shenzhen Stock Exchange (SZSE) and holds confirmed Tier 1 bankable status, underscoring its financial resilience and long-term supply reliability. JA Solar's portfolio spans 524 modules with a maximum rated power of 740 Wp and an average of approximately 441 Wp. Peak module efficiency reaches 24.4%, with an average across the portfolio of roughly 20.9%. PERC remains the dominant cell technology at around 52% of the lineup, with newer generations complementing the range. Bifacial modules account for approximately 44% of the portfolio, making JA Solar well-suited for residential rooftop installations, flat-roof commercial C&I projects, and utility-scale ground-mount arrays alike. The average temperature coefficient of Pmax stands at approximately -0.32%/°C, indicating solid performance in warm conditions, and the average product warranty across the portfolio approaches 28 years. Depozit Solar, as a distributor with no proprietary manufacturing, offers no comparable technical benchmarks of its own. For international buyers comparing the two, the distinction is fundamental: JA Solar is a vertically integrated global manufacturer with a broad, well-documented product range, independent lab validation (including repeated PVEL Top Performer recognition), and the financial standing expected by project lenders. Depozit Solar should be evaluated as a regional distribution channel - its value lies in local availability and service rather than in any proprietary panel technology or manufacturing capability.
