Hello, the investment cost per W of photovoltaic energy production has decreased significantly compared to previous years. In 2020, the terminal sales price in the market is generally 4-5 yuan per watt for a 10 kW power station. the investment price is less than 50,000 yuan, and the lifespan of the power plant can reach 25 years. The cost can be recouped in the first 6 years or so, and everything after that is income.
The income of power plants is mainly divided into three parts: electricity savings from free electricity, state subsidies and income from electricity sales. The electricity generation subsidy in 2020 is 0.08 yuan per kilowatt hour. The year 2021 has not yet been announced. We will have to wait until March or April for the announcement to be made.
I hope this helps!

From an accounting point of view, it is very cheap compared to thermal, hydroelectric and wind power. First of all, thermal power, water power and wind power should be selected in areas that do not affect social activities and are subject to geographical restrictions, so a long power grid should be built while there is one. suitable free space, and can even be installed on the roof of a building and connected to the network. Extremely practical and inexpensive. Secondly, compared with thermal power, hydropower, nuclear power and other power generation equipment, solar photovoltaic power generation equipment is very simple, and its cost is also much lower considering factors such as difficulty and construction period. In addition, production equipmentction of photovoltaic solar energy are relatively simple to maintain, even if there is a problem, it is a local problem. There is no need to stop production for maintenance, and the operating cost is also very low. Therefore, for large-scale power generation equipment projects, solar photovoltaic power generation equipment is not expensive. If it is domestic distributed power generation equipment, it should be considered from a cost recovery perspective. Generally speaking, the cost can be recovered in 5 to 7 years and the service life is more than 30 years. an investment is a choice with an ideal rate of return.
