Looking for the absolute cheapest way to hit domestic content requirements without paying a premium? These 550W Heliene Bifacial Panels (HE-144M-520-HC-M10BF-SL) are b-grade, meaning they don’t come with a manufacturer warranty—but they do offer verified 12% domestic content and full BABA compliance. If your project needs to qualify for the domestic content bonus tax credit and you're not interested in shelling out 50 cents a watt for top-tier American-made panels, this is the most cost-effective option on the market. A solid choice for developers and EPCs looking to maximize margins while still checking the federal incentives box. Panels are still sealed and ship fast by the truckload.
Built with advanced bifacial PERC cell technology, these panels deliver superior energy yield by capturing light from both the front and rear sides. Their robust construction and high power density make them ideal for maximizing energy output in constrained spaces or for lowering BOS costs across larger installations.
Manufactured in America and backed by Heliene’s strong reputation for quality, these modules meet international certifications for safety, performance, and durability. This model is well-suited for developers and EPCs sourcing modules that fulfill U.S. domestic content requirements without compromising on Tier 1 performance and reliability.
Available exclusively by the truckload, this offer is ideal for buyers sourcing bankable panels at volume with long-term project viability in mind.
