The 125/250kW on-grid commercial and industrial solar power system is an integrated photovoltaic solution engineered for medium- to large-scale C&I applications. By combining high-efficiency solar modules, commercial-grade grid-tied inverters, and optimized mounting and electrical components, the system ensures stable and long-term solar energy generation under demanding operating conditions. Operating in grid-tied mode, the system supplies clean solar electricity directly to commercial or industrial loads while exporting excess power to the utility grid. It is ideally suited for factories, industrial parks, warehouses, and large commercial rooftops seeking to reduce electricity costs and improve sustainability performance.
