Gamko New Energy vs SunEvo Solar - solar panel manufacturer comparison

Gamko New Energy, formally Nantong Gamko New Energy Co., Ltd., is a Chinese solar module manufacturer headquartered in Nantong, Jiangsu province, established in 2017. According to company-sourced data, its annual manufacturing capacity reached approximately 1.2 GW in 2023, and it distributes products to more than 177 countries, including several major European markets such as Germany, France, Italy, and the Netherlands, supported by EU-based warehouse stock. No independent confirmation of BloombergNEF Tier 1 status was found in available sources, placing Gamko in the category of a smaller, export-oriented supplier. SunEvo Solar Co., Ltd., headquartered in Hefei, Anhui province, was founded in 2011 - six years earlier than Gamko - and self-describes as a Tier 1 solar module manufacturer, though independent verification of BloombergNEF classification was not confirmed by publicly available third-party sources. The company reports over 14 GW of photovoltaic panels installed across more than 80 countries and more than 30,000 residential and commercial systems deployed globally, suggesting a larger cumulative track record. In terms of institutional footprint and years of operation, SunEvo holds the stronger position between the two.

Gamko's product portfolio spans a wide power range - from small panels of a few watts up to modules exceeding 700 W - incorporating PERC and TOPCon cell technologies, including bifacial and flexible module variants. The lineup holds IEC 61215, IEC 61730, CE, ISO 9001, and ISO 14001 certifications, enabling compliant distribution in European markets. SunEvo's catalog covers a similarly broad wattage range and draws on a wider technology mix - PERC, TOPCon, HJT, and BC cells - targeting residential rooftop installations, commercial and industrial (C&I) projects, and larger-scale deployments. Its certifications include UL, TUV, MCS, INMETRO, and RETIE, positioning the brand for North American, British, and Latin American market entry alongside European distribution.

For international buyers evaluating both brands, SunEvo's longer operating history and larger documented installation base give it a marginal edge in terms of reference projects and market credibility. Gamko may appeal to buyers seeking competitive pricing and flexible supply arrangements from a smaller, more agile manufacturer with EU logistics in place. For standard residential or small commercial applications, the two brands are broadly comparable in technology offering and market tier; the deciding factors should be local distributor support, warranty terms, and verified after-sales service availability in the target market.
