What DAH Solar does
DAH Solar (legal entity: Anhui Daheng Energy Technology Co., Ltd.) is a China-based vertically integrated solar manufacturer founded in 2009 and headquartered in Hefei, Anhui Province. The company researches, manufactures, and sells photovoltaic modules, integrated PV systems, and energy storage solutions, serving utility-scale, commercial & industrial (C&I), and residential customers across more than 120 countries. Its core technology stack is built on N-type TOPCon cells, a globally patented Full-Screen Anti-Dust frameless module design (128 curved R-corner side frame enabling self-cleaning and 6-15% power generation gain), and DBB (busbar-free) cell architecture that shortens the current transmission path by 40%. The flagship product lines include the Full-Screen anti-dust module family (Full-Screen, V6 High Power, Colored, All-Black variants), the SolarUnit integrated PV system (world's first factory-integrated module-plus-microinverter product with up to 97.60% system conversion efficiency), LiFePO4-based low-voltage and high-voltage rack-mounted batteries (6,000-8,000+ cycle life), hybrid inverters, and containerized energy storage for utility-scale applications.
The business model is primarily project-based hardware sales through a direct enterprise sales motion, supplemented by wholly-owned regional branches in Brazil, Japan, and Europe, and a global distributor/dealer network. Pricing is quote-based across utility-scale, C&I, and residential tiers, with no public pricing page. Revenue is generated across four streams: PV module sales, SolarUnit integrated systems, energy storage systems, and power station investment/construction/O&M services. The company operates six manufacturing bases in China (Hefei HQ, An-Chao Chaohu, Ma'anshan, Wuhu Nanling, Liuzhou Guangxi under construction, Jinzhong Shanxi pre-construction) with combined capacity of 20GW, holds more than 200 R&D patents, and is recognized as a BloombergNEF Tier 1 PV module manufacturer (Q2 2024, Q3 2025, Q4 2025). The 2023 revenue was 6 billion CNY, and the company has been pursuing an IPO since 2020, including a shareholding system reform in 2023.
Customer segments are diversified by both use case and geography. Utility-scale customers include large ground-mounted power stations (e.g., 134MW Anhui Fulide project). C&I deployments include factory rooftop installations for automakers such as NIO (32MW, Hefei) and DFSK (37MW, Shiyan). Residential and architectural applications are served via SolarUnit rooftop systems, balcony systems, and BIPV-colored modules, including a 200-unit villa project in Thailand. Storage and inverter products are compatible with eight major inverter brands (SMA, Victron, SolarEdge, Deye, Solis, GoodWe, Growatt, Luxpowertek), enabling broad multi-vendor deployment.
