Q-Cells vs Zun Power - solar panel manufacturer comparison

Q-Cells, now operating as Hanwha Q CELLS, traces its roots to a German solar pioneer founded in 1999 and acquired by South Korea's Hanwha Group in 2012. The combined entity is a confirmed Bloomberg NEF Tier 1 manufacturer, a designation reflecting proven bankability with commercial lenders across multiple financed projects. Its global annual module production capacity reaches approximately 11 GW, and in the United States alone the company has committed $2.5 billion to build a complete domestic supply chain across two Georgia facilities in Dalton and Cartersville, targeting up to 8.4 GW of US-based production capacity. Zun Power, operating under the GMA Solar brand, is a much smaller Montreal-based manufacturer with a modern automated production line and certifications including CSA (Canada/USA) and TUV Rheinland. No Bloomberg NEF Tier 1 designation for Zun Power was found in available industry sources, and its annual production scale is not publicly documented at a comparable level. On institutional footprint, Q-Cells is the substantially larger and more widely recognized player.

Q-Cells is best known for its Q.ANTUM cell technology, a PERC-derived architecture, and has more recently expanded into TOPCon product lines. Its panels are sold across residential rooftops, commercial installations, and utility-scale ground mounts globally, with efficiency ratings reaching up to approximately 22.5% in current product families. Zun Power targets commercial, industrial, agricultural, and off-grid mobile applications with a product range spanning small-wattage portable panels up to 670 W modules, and its catalog incorporates PERC, TOPCon, and bifacial formats, though independent field-test reviews of its panels are sparse in major English-language solar publications.

For most buyers in 2025 - particularly those financing a residential or commercial project where lender approval and long-term warranty coverage matter - Q-Cells is the safer default. Its Tier 1 status, US manufacturing presence, and depth of independent third-party reviews reduce counterparty risk. Zun Power may be a practical option for buyers in Canada seeking a locally sourced supplier for commercial or off-grid projects, but the absence of comparable bankability documentation warrants additional due diligence.
