Investment cost and rate of return of distributed photovoltaics?
The investment cost and rate of return of distributed photovoltaics can vary due to factors such as project scale, location, type of photovoltaic modules, installation method, and electricity price policy. The following are some reference information on the investment cost and return rate of distributed photovoltaic projects in general:
1. Investment cost
Photovoltaic modules: Photovoltaic modules are the core components of distributed photovoltaic systems, and their prices depend on the type and brand. In the investment cost, photovoltaic modules usually occupy a large proportion.
Inverter: The inverter converts the direct current generated by the distributed photovoltaic module into alternating current, and the price of the inverter is also an important part of the investment cost.
Structural support and installation: The support and labor installation costs for installing photovoltaic modules are also included in the investment cost.
Cables and electrical equipment: Cable routing and electrical equipment are an essential part of the system and part of the investment cost.
System design and engineering: including system design and engineering costs.
2. Income and rate of return
Power generation income: Distributed photovoltaic systems generate income by injecting electricity into the grid or providing electricity for their own electricity consumption. Benefits are related to solar resources, system performance, and electricity price policies.
Saving electricity bills: Distributed photovoltaic systems can reduce electricity purchased from the grid, thereby saving electricity bills.
Energy subsidies: In some regions, the government may provide subsidies or incentives for solar photovoltaic power generation, which can also be a source of income. The rate of return can be assessed by calculating the payback period. ROI refers to the time required to pay back the investment cost, usually calculated in years. A shorter payback period means a higher rate of return.
It should be noted that the investment cost and rate of return of distributed photovoltaic projects will be affected by many factors, including energy policy, electricity price policy, solar resource conditions, project scale, component quality, etc. Before investing in distributed photovoltaic projects, it is best to conduct detailed economic analysis and feasibility studies to fully evaluate the potential returns and risks of the project.
