Solar Building Coating SunPaint Enters Mass Production: Spray It on Walls and Generate Electricity

Australian perovskite solar company SunDrive announced on June 30, 2028, that its SunPaint solar coating has entered mass production. SunPaint is a liquid paint containing perovskite nanoparticles that can be sprayed directly onto building facades, rooftops, and even windows. Once dried, it forms a transparent or semi-transparent solar thin film. Each square meter of SunPaint produces approximately 50 watts under standard sunlight conditions. A building with 100 square meters of exterior wall area could theoretically install a 5 kW solar system generating about 5,000 kWh annually. SunPaint's installation cost is just one-third of traditional solar panels and requires no mounting brackets or professional installation. CEO said: "SunPaint turns every wall into a power generator—buildings' entire surface area can be utilized."
