Gamko New Energy vs ARTsolar - solar panel manufacturer comparison

ARTsolar is a South African manufacturer headquartered in Pinetown (Durban), founded in 2010 under the name African Renewable Technologies. It is the only 100% locally owned solar panel producer in South Africa and holds TUV (IEC) and SABS certifications. The company does not appear on BloombergNEF's Tier 1 list in its own right, but it has structured its bankability through successive partnerships with globally recognised Tier 1 brands - first LONGi, then Talesun, and most recently JA Solar, which in 2025 formalised a joint arrangement to assemble 340 MW of n-type DeepBlue 4.0 Pro modules at ARTsolar's Durban facility. Gamko New Energy (formally Nantong Gamko New Energy Co., Ltd.) is a Chinese manufacturer headquartered in Hai'an, Nantong, Jiangsu Province, operational since approximately 2017. Its reported annual capacity reached 1.2 GW in 2023, and it carries a broad set of international certifications including IEC61215, IEC61730, ISO9001, ISO14001, INMETRO, and JPEA, though no BloombergNEF Tier 1 designation was confirmed in available sources. On institutional footprint, Gamko's larger manufacturing scale and wider certification portfolio give it a broader global reach, while ARTsolar's strength is concentrated in the South African market.

ARTsolar's current product focus is utility-scale and commercial projects within South Africa, with its 340 MW assembly line producing large-format TOPCon modules under its JA Solar partnership. Its local-content credentials are important for developers participating in South Africa's government procurement programmes, where locally manufactured content earns preferential scoring. Gamko's catalog is considerably wider, spanning 5 W to 800 W, covering residential rooftops, commercial installations, and ground-mounted utility projects across export markets. The company offers both PERC and N-TOPCon cell technologies, as well as bifacial and flexible form factors, positioning it as a volume-oriented mid-market supplier serving multiple geographies.

For a buyer based in South Africa, ARTsolar is the more relevant choice if local content compliance or domestic supply chain resilience matters - advantages that Gamko simply cannot match. Outside of that regulatory context, Gamko's larger scale and more diverse product range make it the more flexible default for international or multi-market procurement, though the absence of a confirmed Tier 1 classification means that either brand will require careful due diligence with project lenders before deployment in project-financed schemes.
