What SolarSpace does
SolarSpace (江苏中润光能科技股份有限公司), founded in 2011 and headquartered in Xuzhou, Jiangsu Province, China, is a privately held manufacturer of high-efficiency photovoltaic (PV) cells and modules serving global utility-scale, commercial and industrial (C&I), and residential solar markets. The company operates 30GW+ of solar cell production capacity and 6GW of module assembly capacity across facilities in China and overseas, positioning it among the largest cell producers globally. It was reinstated to the BloombergNEF Tier 1 global solar module manufacturer list in Q2 2024 and named to the Forbes China 2024-2025 Sustainable Development Industrial Enterprise list in June 2025.
The company's product portfolio spans two technology platforms. Its P-type PERC lineup includes the G12 (210mm) and M10 (182mm) cell formats and the Lumina I monocrystalline module. Its N-type TOPCon lineup adds the G12, M10, and G12R cell variants plus the Lumina II module, reflecting a deliberate transition toward higher-efficiency N-type technology. Sales are conducted B2B via direct enterprise field sales to project developers, EPCs, and wholesale module assemblers, supported by a seven-language website (Chinese, English, Portuguese, Spanish, German, Italian, French) and active participation in flagship industry events including SNEC and Intersolar Europe. Pricing is quote-based and tied to volume and specifications rather than publicly disclosed.
SolarSpace generates revenue through hardware sales of solar cells and modules, with volume-based pricing tied to wattage capacity and cell efficiency tier. The company has raised capital through multiple private rounds between 2021 and 2022, including a $412 million round in November 2022 from investors such as EBI Investment, Sinochem Capital, SDIC Capital, and Yingke Capital. It has not pursued a public listing. Revenue is not publicly disclosed; based on capacity, headcount of 1,001-5,000 employees, and industry ASP benchmarks, implied annual revenue falls in the $1B-$5B band, though solar pricing pressure in 2023-2024 creates meaningful downside risk to that estimate.
