Jinko Solar vs Panasonic - solar panel manufacturer comparison

Jinko Solar, founded in 2006 and headquartered in China, is one of the world's largest solar module manufacturers, listed on the NYSE with a production capacity of 130 GW and a confirmed Tier 1 bankable status. The company employs over 33,800 people and has surpassed 300 GW of cumulative global shipments, making it a dominant force across every major market. Its portfolio of 545 modules spans output levels up to 735 Wp, with an average efficiency of 22.0% and a laboratory-verified TOPCon cell record of 27.79%, independently confirmed by Germany's ISFH. Panasonic, a Japanese conglomerate founded in 1918 and listed on the Tokyo Stock Exchange, built a premium reputation in the residential solar segment through its EverVolt HJT lineup. However, Panasonic formally exited the solar and battery storage business in April 2025, halting all new manufacturing while committing to honor its existing 25-year warranties on installed products.

Jinko's broad lineup - with nearly 32% of its portfolio consisting of bifacial modules and a growing TOPCon share of 39.4% - positions it strongly for utility-scale ground-mount projects, large commercial and industrial (C&I) installations, and any procurement requiring consistent, high-volume supply. The average warranty of 28.5 years across the portfolio adds further financial security for project developers and EPCs. Panasonic's compact range of 25 modules topped out at 430 Wp and 22.2% maximum efficiency, but its defining technical advantage was the HJT temperature coefficient of -0.267%/°C - meaningfully better than Jinko's -0.308%/°C and among the best values in the industry. This made Panasonic panels an outstanding choice for residential rooftop installations in warmer climates, where thermal derating is a significant factor in annual yield.

For buyers making new procurement decisions today, Jinko Solar is the only viable option of the two - offering scale, supply chain depth, competitive pricing, and active product development. Panasonic panels may still surface through distributor stock or secondary markets, and their HJT quality is genuinely excellent, but with manufacturing permanently discontinued, no long-term supply strategy can be built around the brand. Buyers who specifically need low temperature coefficients comparable to Panasonic's HJT performance should explore alternative HJT manufacturers that remain active in production.
