Seoul National University Technology Holdings announced that it has invested in SolarToz, a climate tech startup that upcycles discarded solar panels and converts them into agricultural infrastructure.
SolarToz possesses two core technologies for utilizing solar panels that have reached the end of their useful life or whose power generation efficiency has declined. First, it processes glass extracted from waste panels using proprietary surface decontamination technology and a nano-structuring process to produce tempered glass with improved light transmittance and anti-contamination capabilities. This glass is characterized by higher light transmittance and self-cleaning properties compared to conventional glass.
Additionally, reusable, aged solar panels can be remanufactured into regenerative solar panels by restoring their power generation performance and enhancing their surface properties. This technology is considered an upcycling model that transforms waste solar panels from mere disposal into high-value resources.
SolarToz is utilizing this technology to build energy-self-sufficient glass greenhouses. These greenhouses are designed to increase crop productivity while reducing energy consumption through glass that is more durable and light-diffusing than conventional vinyl greenhouses. They also feature enhanced responsiveness to external weather changes.
