What ET Solar Group does
ET Solar Group is a privately held Chinese photovoltaic module manufacturer founded in 2005 and headquartered in Nanjing, Jiangsu, with supplementary operations in California, USA. The company manufactures monocrystalline silicon PV modules and sells them directly to residential, industrial, commercial, and utility clients worldwide, holding BNEF Tier 1 PV Module Manufacturer status and reporting cumulative deliveries exceeding 7.2 GW. Its core product lineup comprises the M660BH series (360W-380W) and M672BH series (425W-455W, available in black-on-black and bifacial variants), with datasheets downloadable from the company website and positioning centered on levelized cost of electricity (LCOE) optimization.
The company operates a B2B direct sales model with quote-based pricing rather than publicly disclosed list prices, and supplements hardware sales with tailored finance solutions intended to mitigate project development risk. Marketing is primarily conducted through the corporate website, including contact-form lead capture and downloadable product datasheets, rather than through disclosed third-party channels or partner ecosystems. Its customer base spans four horizontal segments — residential, industrial, commercial, and utility — with utility designated as the primary segment. ET Solar raised a $50 million round in March 2008 led by Tsing Capital, and disclosed leadership consists of founder Xinghua Wang and Vice President / Chief Sales Officer Dennis She. In June 2026 the company filed suit against CNA Insurance in the Northern District of California relating to a May 2023 fire at a Red Bull North America warehouse where its panels had been installed.
