## Summary

GL Solar is a micro-sized Italian company founded in 2000 with between 1 and 10 employees. It operates exclusively as a distributor of photovoltaic products - not as a manufacturer - and holds no proprietary panel portfolio of its own. The company acts as a reseller of modules from major international brands including Trina Solar, AIKO, and Tongwei, serving installers primarily in Italy and across Europe. Jinko Solar, by contrast, is one of the world's largest solar module manufacturers, founded in China in 2006, employing over 33,800 people, and carrying a stated annual production capacity of 130 GW. It is listed on the NYSE and holds Tier 1 bankable status, with a product catalogue spanning 545 module models, a maximum panel output of 735 Wp, average module efficiency of approximately 22%, and an average product warranty of nearly 28.5 years. The company's leading cell technology is TOPCon, and Jinko has set a world record for n-type TOPCon cell efficiency at 27.79%.

Given that GL Solar produces no modules of its own, it cannot be assessed on technical parameters such as cell technology, temperature coefficients, or efficiency ratings. Its value proposition lies in offering installers convenient access to multiple brands through a single distribution channel - useful for smaller Italian contractors, but providing no manufacturer-backed warranty or independent quality assurance. Jinko Solar, on the other hand, serves a broad range of market segments with credibility: its Tiger Neo TOPCon series is widely deployed in residential rooftop installations, commercial and industrial C&I projects, and large-scale utility ground-mount farms. With roughly 32% of its portfolio consisting of bifacial modules and 11 consecutive years as a PVEL Top Performer backed by over 300 GW of global installations, Jinko offers a well-documented track record of real-world performance.

For international buyers evaluating the two, the comparison is structurally uneven - GL Solar is a trade intermediary, while Jinko Solar is a tier-one global manufacturer. Buyers seeking a bankable, technically verifiable, and warranty-backed module for any serious installation should look to Jinko Solar, whereas GL Solar may only be relevant as a regional logistics or sourcing partner for specific European markets.
