It holds Tier 1 bankability recognition from both Bloomberg NEF and S&P Global's PV module supplier list - dual institutional validation that carries weight with project lenders. With an annual module production capacity of roughly 21 GW and reported shipments of 13.4 GW in the first half of 2025 alone (a 64% year-over-year increase), DMEGC ranks inside the global top ten module manufacturers. Jolywood is also a Chinese company, smaller in scale at an estimated 3 GW of annual module production, but it too appears on the Bloomberg NEF Tier 1 list and has built a distinct technical identity as one of the earliest commercial developers of N-type cell architecture. In terms of institutional footprint and raw shipping volume, DMEGC carries the larger presence. On product families, DMEGC's current lineup centers on N-type TOPCon monocrystalline modules, with some legacy PERC models still in circulation. Its Infinity RT series has earned independent recognition from RETC and Kiwa PVEL as a top-performing module, and the company has held EUPD Top Brand PV status in Europe for six consecutive years, reflecting strong distribution depth across residential, commercial, and utility segments. Jolywood staked its brand on N-type technology from early on - its TOPCon cells reached a confirmed lab efficiency of 26.7% in 2023 - and the company also has research activity in heterojunction technology. Jolywood typically targets buyers who prioritize N-type performance credentials, backing modules with a 30-year linear performance warranty and a 15-year product warranty. For a typical buyer in 2025, DMEGC is the more practical default: independently validated, widely stocked across Europe and other key markets, and financially scaled to satisfy lender requirements on larger projects. Jolywood suits technically motivated buyers or developers specifically seeking early-mover N-type credentials, but its smaller installer base outside China means due diligence on local support should be factored in before committing. \---LINKS--- \- https://www.prnewswire.com/news-releases/dmegc-solar-listed-as-sp-globals-tier-1-pv-module-supplier-302554935.html \| DMEGC Solar listed as S&P Global Tier 1 PV module supplier \| article \- https://www.solarchoice.net.au/products/panels/dmegc-solar-review/ \| DMEGC Solar Panels - Independent Review by Solar Choice \| review \- https://www.solarchoice.net.au/products/panels/jolywood-solar-panel-review/ \| Jolywood Solar Panels - Independent Review by Solar Choice \| review \- https://www.infolink-group.com/energy-article/solar-topic-infolink-2025-global-module-shipment-ranking-combined-shipments-reach-536-gw \| InfoLink 2025 global module shipment ranking - 536 GW combined \| article \- https://comparepv.com/reviews/jolywood \| Jolywood Solar Panels Review 2026 - ComparePV \| review Sources: \- \[DMEGC Solar listed as S&P Global's Tier 1 PV Module Supplier\](https://www.prnewswire.com/news-releases/dmegc-solar-listed-as-sp-globals-tier-1-pv-module-supplier-302554935.html) \- \[DMEGC Solar Panels - Independent Review by Solar Choice\](https://www.solarchoice.net.au/products/panels/dmegc-solar-review/) \- \[Jolywood Solar Panels - Independent Review by Solar Choice\](https://www.solarchoice.net.au/products/panels/jolywood-solar-panel-review/) \- \[InfoLink 2025 global module shipment ranking\](https://www.infolink-group.com/energy-article/solar-topic-infolink-2025-global-module-shipment-ranking-combined-shipments-reach-536-gw) \- \[Jolywood Solar Panels Review 2026 - ComparePV\](https://comparepv.com/reviews/jolywood) Written by claude-sonnet from the figures above. ## Other comparisons - [DMEGC vs A.B.
