DMEGC Solar Unveils Innovative Steel Frame Modules for Enhanced Efficiency

DMEGC Solar has made waves in the renewable energy industry with the launch of their latest series of steel-frame photovoltaic modules. This groundbreaking development signifies a major engineering shift away from traditional aluminum frames, presenting both technical and environmental advantages.

The Advantages of Steel

The decision to use steel for these new photovoltaic modules stems from several compelling reasons. DMEGC Solar emphasizes that the steel used in these modules has a significantly higher tensile strength compared to conventional aluminum alloys. Specifically, it boasts twice the strength, allowing it to endure extreme mechanical loads—effectively managing snow loads up to 6000Pa and wind loads reaching 5000Pa when installed correctly.

One of the key improvements in reliability is attributed to steel's Coefficient of Thermal Expansion (CTE), which measures how much a material expands when heated. The CTE of steel is approximately 12 (10⁻⁶ m/k), which closely aligns with that of glass (6.9), unlike aluminum (23). This compatibility minimizes environmental stress and reduces the likelihood of micro-cracks over the module's lifespan.

Innovative Cross-Section Design

Among the most notable features of this launch is the unique cross-section design of the steel frame. Unlike traditional module frames that cast shadows on the rear side—impacting energy capture—DMEGC’s innovative
