Opportunities and risks for development of photovoltaic power plants

26 Oct 202186

Blue jay believes that distributed photovoltaic power generation currently faces both opportunities and challenges. Among them, the determination of carbon peaks and carbon neutral goals has injected vitality into the renewable energy market mainly in the development of photovoltaic and wind power, which has created innovations in the development of photovoltaics. In the great market opportunity.

1. Development Opportunities of Distributed Photovoltaic

The development of photovoltaic technology has greatly reduced the prices of photovoltaic-related products, and the decline in construction costs and the economic benefits of clean power have stimulated the enthusiasm for investment. The annual return on investment in most regions is higher than 10%.

Distributed photovoltaic construction is relatively small in scale and has good mobility. It can make full use of idle plant, commercial buildings and other rooftop resources, and intensively use agricultural facilities and other resources to install photovoltaic power generation, which can be consumed nearby to reduce power loss caused by long-distance power transmission. There is basically no problem of abandoning light and limiting electricity.

2. Risks in the construction and operation of photovoltaic power plants

Blue jay found that there are still many risks in the construction and operation of photovoltaic power stations. The main risks faced by photovoltaic power stations throughout the life cycle are:

01 Site risk

The construction site of distributed photovoltaic power station is more complicated, usually including wasteland, waste mine settlement area, building roof, water surface, etc. Risks such as the sinking of the construction site in the abandoned mining area and the load on the roof of the building need to be understood during investment and construction and effectively avoided in the early stage of the project.

02 Site property rights risk

Many distributed photovoltaics are constructed by means of site leasing or cooperation, etc., and the property right certificate cannot be applied for. In particular, once the homeowners and plant renters change, their roof leases and the consumption of generated electricity may change significantly. The consumption and consolidation of power stations that are self-generated or self-contained and surplus electricity are connected to the grid may occur. Internet access risks, etc.

03 Grid connection risks caused by changes in grid structure

With a large number of industrial and commercial rooftop power stations, the construction of distributed photovoltaic power generation by residential households and a large number of access to the user-side power grid will cause the user-side power grid to have high grid voltage, increased fluctuations, and photovoltaic inverters should be over-voltage tripped, resulting in abnormal power generation and Risks such as damage to the user's electrical appliances.

04 Electricity price risk

With the development of renewable energy power generation, the risk of electricity price fluctuations or price cuts also exists. Although the risk of electricity price cuts is relatively small, this risk always exists.

05 Quality and life risk of power station equipment

Although the performance and life of the main equipment of photovoltaic power plants can meet the service life of more than 20 years, some components and inverters still have the problem of short-term damage.

06 Natural disaster risk

Photovoltaic power plants have a large investment, a long investment return period, and a greater risk of interference from uncertain factors such as natural disasters. Natural disasters that are irresistible will cause huge damage to photovoltaic power generation such as component damage and bracket dumping.

07 Operational accident risk

There are still many operational accident risks in the operation of photovoltaic power stations. Although the operation and maintenance costs of photovoltaic power stations are relatively small after the completion of the photovoltaic power station, the risks it faces still exist.


In the process of construction and operation of distributed photovoltaic power stations, great attention must be paid to risk investment analysis and operation and maintenance management, and the operation and maintenance of the power station must be strengthened to ensure the stable operation of the power station. A high-performance power station requires not only the correct design and excellent construction quality, but also high-level production, operation and maintenance and other post-production services. Correct operation and maintenance can not only greatly improve the life of equipment and power stations, but also allow the power stations to operate efficiently, greatly increase power generation, and avoid risks.
