New Report: Domestic Steel Solar Module Frames Show 90.4% Emissions Reduction from Current Aluminum Frames

Mar 12, 2024

Bend, OR – March 12, 2024Boundless Impact Research & Analytics today released the new Environmental Impact Report on Origami Solar steel module frames, which finds emissions from domestically-produced steel solar module frames to be 90.4% lower than current aluminum frames manufactured in China. The independent, rigorous, and data-driven report details the low carbon footprint associated with steel solar module frames produced domestically by Origami Solar in the US and Europe, a reliable and sustainable alternative to imported aluminum frames. Origami Solar commissioned the independent report.

“We at Meyer Burger believe that sustainability should be at the forefront of every industry, especially solar manufacturing,” said Daniel Menzel, Chief Operating Officer at Meyer Burger Technology AG. “We are proud to see the innovations being made by Origami Solar and are excited about the potential for domestic steel module frames to drive significant emissions reductions and transparency in our industry.”

The data aligns Origami Solar’s steel module frames with the mission of the Ultra Low-Carbon Solar Alliance and the Global Electronics Council’s EPEAT Ultra-Low Carbon Solar Criteria to ensure that a major component of the PV supply chain is low-carbon and to accelerate embodied carbon reductions across the solar industry supply chain. This also provides a clear, data-backed alternative to carbon-intensive aluminum frames for solar module manufacturers pursuing EPEAT registration to consider.

“To decarbonize solar manufacturing, we need to make improvements across the entire supply chain,” said Michael Parr, the Executive Director of the Ultra Low-Carbon Solar Alliance. “This updated assessment on Origami Solar’s steel frames for solar panels demonstrates significant life cycle carbon reductions as compared to commonly used imported frames made from virgin aluminum in China. Origami produces frames that can help solar panel producers meet the stringent carbon footprint standards in EPEAT.”

Origami Solar’s frames are produced via precision roll-forming of recycled steel, enabling localized production, higher performance, and reductions in embodied carbon compared to conventional aluminum extrusion techniques predominant today. The production of the Origami Solar module frames is based in the US and Europe, enabling less than one-day shipping to regional customers to reduce transportation and manufacturing costs and emissions.

“If we are going to curb the climate crisis, we are going to have to make educated decisions backed by hard data,” said Mike Gray, COO of Origami Solar. “The data here could not be any clearer: steel is a far cleaner option for the solar industry than the current industry-standard aluminum frames. Steel module frames are also superior in strength, durability and value than aluminum. The data has told the solar industry what it must do, namely switch to steel solar frames as quickly as possible. The only question now is whether the solar industry will listen.”
