Chinese solar module and energy storage manufacturer, GroupGCL SI, has described its renewed SiRo module portfolio as a shift toward scenario-specific engineering across distributed and utility-scale markets. The company outlined how its SiRo concept, “Silicon as the Core, Marching Toward Zero,” was used to guide technology development. The SiRo T Series was presented with Anti-Dust and Marine variants that were designed to manage low-tilt industrial dust, coastal corrosion, moisture and wind stress through modified frames, reinforced structures, upgraded coatings and enhanced sealing systems. The SiRo B Series was reported with upgraded GPC 2.0 cell architecture, aesthetic features and efficiency-focused materials and processing methods. GCL SI also stated that its SiRo P Series was planned for 2026 with perovskite-tandem technologies aimed at higher efficiency and improved temperature behaviour.
