The cost of electricity, simply speaking, is the average cost per kWh of the power plant. Most people know that the lower the cost, the greater the market competitiveness, and the greater the profitability of the company. Therefore, in the electricity market, reducing the cost of electricity is always The focus of everyone's attention is that governments, companies, and research institutions are all looking for ways to reduce the cost of electricity.
Specifically for the photovoltaic industry, although the manufacturing cost of photovoltaic modules has dropped by nearly 80% in recent years, the cost of photovoltaic power is still higher than traditional energy.
I often heard that photovoltaic power generation is expensive and I have never scrutinized it. How expensive is it? Is investing in photovoltaic power stations to make money? How much is the cost? How much is the revenue? Is it worthwhile to do photovoltaic power plants? I believe these are the most common users. Concerned about the problem. Let us calculate this account carefully. The author consulted the current equipment and construction costs, and took a small power station in the southern Anhui power grid as an example to calculate the cost of photovoltaic power generation, income, etc. Here we generate electricity. Data examples to illustrate the cost of electricity:
Take a small photovoltaic power plant of 5 KW in Hebei province (ie with a 5.2 kW component installed) as an example. Let's calculate the cost and profit of photovoltaic power plant.
Considering the sunshine factor, Hebei Province is a northern China region with light level III. It is at a medium level. Geographical location and light levels are among the regions where photovoltaics are relatively good. Then we look at the cost of photovoltaic generation from the perspective of revenue, cost, and revenue.
income
According to work experience and life advice, the author calculated: The installed capacity of 5.2 kilowatts, the cumulative power generation should reach 7980 degrees.
After calculation, the average power generation per day of the system is 22.8KWH (commonly known as degree), the average lifetime of photovoltaic modules is 25 years, and the total decay rate in 25 years is 20%. After calculation, the total generating capacity of the photovoltaic power generation system for 25 years is 166550 Degree. The power generation in 25 years will be at least RMB 174,877.50 according to the current electricity price.
cost
For the time being, we have built this small-scale photovoltaic power station according to our own capital contribution. According to the current cost of photovoltaic power plants, polysilicon components (publicly announced by the Ministry of Industry and Information and Class A+ components) are taken as an example. The cost of equipment, transportation, and installation is about 6,500 yuan per kilowatt. About the total investment in this power station is about 65,000 yuan, and the total power generation is 166,550 degrees. In this case, the power generation cost is 0.39 yuan/degree.
income
From the comparison of costs and benefits, the investment in the 25 years is 0.39 yuan, but there are state subsidies. The total return should be 0.75 yuan. In this way, the profit is 0.36 yuan, and the total return on investment is 92.3%. Visible, investment in photovoltaics can be comparable to any one investment, is basically a profitable! It is no wonder that the government has now supported the photovoltaic industry as a key support for poverty reduction projects, as a key promotion of pension programs, as a priority for the development of pollution control and management of haze projects.
