The total cost of photovoltaic projects is 3 billion. What is the ratio of labor and materials?

Eight to ten percent. The project owner bears the land use fee, project prophase fee, project construction management fee, project construction supervision fee and project prophase consulting service fee, accounting for 8- 10% of the photovoltaic power generation project. Solar photovoltaic power generation is the most widely used solar power generation technology with the characteristics of modular battery components, convenient installation and maintenance, and flexible use.
