Ground mount, rooftop mount and carport mount are the three core solar PV racking systems, and each fits a different project type: ground mount suits open land and utility-scale plants, rooftop mount suits buildings with structurally sound roofs, and carport mount adds dual-use value to parking areas while requiring the highest structural investment. This guide compares the three systems by installation cost, structural requirements, land use efficiency and typical applications, helping EPC contractors, developers and procurement teams choose the right mounting solution for their site conditions and project goals.

Choosing the right solar mounting system affects installation cost, structural safety and long-term ROI. This guide compares ground mount, rooftop, carport and floating PV mounting systems — covering site conditions, materials, cost and maintenance — to help EPC contractors, developers and procurement teams select the right racking solution for ground, roof, parking lot or water-based solar projects.
