The 70mm x 70mm Square Mini Polycrystalline Solar Panel is an ultra-compact, lightweight photovoltaic module tailored for low-power electronic applications. Encapsulated in a rugged, weather-resistant epoxy resin layer, it delivers a stable 5V to 6V output under optimal sunlight conditions. Its square profile makes it exceptionally easy to integrate into micro-robotics, DIY solar toys, portable Arduino sensor nodes, and classroom science experiments.
