Solar grid-connected systems are widely used in residential rooftops, commercial buildings, industrial parks, and other locations. For residential users, installing a solar grid-connected system can reduce electricity bills and achieve green energy self-sufficiency. For commercial and industrial users, large-scale solar grid-connected systems can significantly reduce dependence on traditional energy sources, lower operating costs, and enhance the company's image.

Solar panels come in many types, mainly classified according to materials, structure, and application scenarios.

Residential Rooftops: Monocrystalline silicon or PERC panels (high efficiency, long lifespan).

Large Power Plants: Polycrystalline silicon or bifacial panels (low cost, high power generation).

Mobile Devices: Thin-film or flexible panels (lightweight, bendable).
