Solar Panels

A foldable portable solar panel is a mobile power generation device that converts solar radiation into electricity based on the photovoltaic effect. Its core structure consists of multiple monocrystalline or polycrystalline silicon photovoltaic cells connected in series, encapsulated within weather-resistant polymer materials. A folding hinge design enables a balance between the deployed surface area and a compact, portable form factor. These devices typically incorporate an MPPT (Maximum Power Point Tracking) circuit to optimize energy output, delivering power via standardized USB-A, USB-C, or DC outputs to charge devices such as smartphones, tablets, portable power stations, and other 12V equipment like car refrigerators. They are primarily designed for outdoor recreation (including camping, hiking, and RV travel), emergency power backup, and off-grid living in areas without grid coverage. The target user base encompasses outdoor enthusiasts, households preparing for emergencies, geological survey personnel, and residents in remote regions. Products often feature an adjustable kickstand for optimal sun exposure angle and boast splash-resistant properties, with power ratings ranging from 5W to 200W.
