DMEGC Solar Launches Steel-Frame PV Modules With S-Shaped Cross-Section and 85% Bifaciality

DMEGC Solar has launched a series of steel-frame photovoltaic modules with an S-shaped cross-section, a design the company says cuts vertical shading on the module's rear by 76% and supports a bifaciality factor of up to 85%. Aktien published the launch on November 10, 2026.

DMEGC Solar's S-Shaped Steel Frame

The new modules replace traditional aluminum frames with steel. According to the company's technical documentation, the steel grade offers nearly double the tensile strength of standard aluminum alloys, allowing the modules to withstand snow loads up to 6000Pa and wind loads up to 5000Pa when properly mounted.

DMEGC points to steel's coefficient of thermal expansion of 12 (10⁻⁶ m/k), closer to glass at 6.9 than aluminum at 23, as a reliability gain that suggests less environmental stress and a lower risk of micro-cracks over the module's lifetime. The S-shaped cross-section increases the unshaded rear area by 3.6% and theoretically raises the bifaciality factor by approximately 2.8%. Combined with new cell technologies and an anti-reflective coating on the back glass, DMEGC states the modules can reach a bifaciality factor of up to 85%.

According to DMEGC's yield simulations, that 85% bifaciality factor translates to annual power generation of 2,078 kWh/kWp/year, an additional 0.6% gain in power generation revenue compared with conventional modules. To address corrosion concerns, DMEGC uses Zn-Al-Mg coated steel (ZAM), and the modules have passed independent testing for salt mist and ammonia resistance.

DMEGC Solar's INFINITY RT 3.0 Rollout

According to akta.pro company records, DMEGC Solar launched the full INFINITY RT 3.0 module series at Intersolar Europe 2026, with the flagship G12RT-B66 reaching 650W, 15W above the 2.0 version, and including residential, C&I and Agri-PV variants with adjustable 3%-48% light transmission. The same records show DMEGC Solar and Munich-based PHOTOMATE signed a strategic cooperation agreement on June 23, 2026, to accelerate PV distribution across Europe, complementing the company's existing Dutch branch operations.
