New materials in the frame
Solar cells, encapsulants, glass, backsheets, and virtually every PV module component have seen rapid changes and improvements over the past 10 years. During that time, module frames have seen relatively little innovation and remain a simple piece of formed aluminum. However, quality concerns, supply chain diversification, domestic content rules, and emissions reduction requirements have frame manufacturers eyeing alternative materials. And while aluminum isn’t going away, suppliers of steel and glass composite frames argue these materials come with various advantages.
