In a groundbreaking shift towards sustainability, a new report by Boundless Impact Research & Analytics has brought to light the significant environmental benefits of using steel in solar module frames over conventional aluminium. 


Commissioned by Origami Solar, a forward-thinking steel frame startup, the findings are a beacon of hope for eco-friendly solar panels and a testament to the potential of sustainable solar panels in combating the challenge of climate change.


A steel-sharp advantage


According to this new report, domestically produced steel frames boast a staggering 90.4% lower emissions than their aluminium counterparts currently being manufactured in China. 


This not only aligns with Origami Solar’s commitment to the Ultra Low-Carbon Solar Alliance and the Global Electronics Council’s EPEAT Ultra-Low Carbon Solar Criteria but also offers a tangible, data-backed alternative for solar module manufacturers. The shift to steel is not just about meeting standards — it’s also about pioneering a low-carbon future for the entire solar industry supply chain.


Strength, durability, and value


Steel's superiority isn't only limited to its environmental credentials. This innovative process not only minimises embodied carbon but also facilitates localised production — slashing transportation and manufacturing emissions and costs. 


Steel: The new industry standard for solar panels?


Mike Gray, COO of Origami Solar, stated that “the data here could not be any clearer. Steel is a far cleaner option for the solar industry than the current industry-standard aluminium frames.” 


It’s a compelling argument for a swift transition to steel solar frames, underscored by the undeniable benefits of strength, durability, and environmental sustainability. Is this a chance for the solar industry to adapt and evolve even further?


The SpotDif perspective


At SpotDif, we’re all about making it easier for you to make informed, environmentally-conscious decisions — especially when it comes to your home. 


It’s important to remember that sustainable solar panels are far more than a choice, but also a commitment to a greener planet and a brighter future. With the spotlight now on steel as a viable, superior alternative for solar panel construction, the path forward is clearer than ever.


Switching to solar is a significant step towards reducing your carbon footprint and embracing renewable energy. It’s also a chance for you to choose the right solar materials, ensuring that they align with your environmental values.
