Japan's dual-purpose silver solar panels blend with buildings' aesthetic

Japanese greentech startup Monochrome Company Limited has introduced a new silver-colored building-integrated photovoltaic (BIPV) system designed to blend seamlessly with building exteriors. Unlike traditional solar panels that are mounted separately, these BIPV panels can be integrated into walls, windows, or roofs, serving both as functional building materials and power generators. The silver variant mimics aluminum with a light-dependent appearance, appealing to architects seeking aesthetic flexibility. The panels measure 6.2 feet by 1.25 feet, are lightweight at 2.7 pounds per square foot, and produce about 75 watts each, while the black version generates 110 watts. Although these BIPV panels are less efficient than conventional solar panels (which typically produce 300–400 watts), they offer superior aesthetics and seamless integration, making them ideal for new constructions or major renovations rather than retrofits. Both versions use durable, corrosion-resistant fluorine-coated galvalume steel and feature IP-68 rated junction boxes
