Tongwei vs Jolywood - solar panel manufacturer comparison

Tongwei is a Chinese manufacturer headquartered in Chengdu, with roots going back to 1992 when it began as an aquaculture feed company before pivoting into photovoltaics. Today it ranks among the world's largest solar producers, with reported cell capacity exceeding 150 GW and module capacity above 90 GW annually - a scale that has earned it a spot on the BloombergNEF Tier 1 list and a debut on the Fortune Global 500 in 2023. Jolywood, by contrast, is a more focused pure-play solar specialist founded in 2008 and headquartered in Changshu, Jiangsu Province. It has maintained consistent BloombergNEF Tier 1 status through recent quarters and carries a cell production capacity of roughly 20 GW alongside around 10 GW of module output - substantial but a fraction of Tongwei's industrial footprint. On sheer institutional scale and vertical integration from polysilicon through finished modules, Tongwei holds the broader market presence.

Both companies are firmly committed to N-type cell technology, but they approach it differently. Tongwei's portfolio spans monocrystalline PERC legacy lines alongside a growing share of TOPCon products, serving residential rooftops, commercial installations, and large utility-scale ground mounts across more than 70 countries. Its 2025 lineup has been recognized as a Top Performer in Kiwa PVEL's PV Module Reliability Scorecard, lending independent credibility to its quality claims. Jolywood positions itself as a pioneer in N-type TOPCon and has also explored heterojunction technology; its February 2025 launch of a 595 W bifacial TOPCon module specifically engineered for harsh environments signals a deliberate push into demanding utility and agri-PV applications rather than mainstream residential volume.

For a typical buyer in 2025, Tongwei is the safer default where supply chain depth, global availability, and third-party reliability validation matter most. Jolywood is a credible alternative - particularly for projects that require high-output bifacial modules in challenging climates - but its smaller manufacturing scale can translate to tighter stock and less installer familiarity in some markets. Neither brand is a poor choice; the decision largely comes down to local distributor relationships and the specific power class needed.
