Installing photovoltaic power generation is about 3 pieces per watt. In 2021, the installation cost of photovoltaic modules has dropped significantly, with the installation cost of 1 watt being about 3 yuan, and the installation cost of 10 kilowatts being estimated to be 30,000 yuan. The installation cost has been reduced, but the subsidy has also been reduced, and in the new policy in 2021, ordinary photovoltaic power plants and commercial photovoltaic power generation are likely to no longer be subsidized, and household distributed photovoltaic power generation will not be subsidized.
The feed-in tariff may be reduced to $1.
Individual installation of photovoltaic power generation, about 5-6 years can return to the cost, the comprehensive return benefit is 15-18%, it should be said that the benefit is better than the general business efficiency. The design life of the photovoltaic system is 25 years, and the usable life is as long as 40 years, so the power generation income after 20 or 30 years is profit, and the cumulative benefits are considerable.
Photovoltaic power generation is based on the photogenerated volt effect at the interface of semiconductors.
It is a technology that converts light energy directly into electrical energy. It is mainly composed of solar panels (modules), controllers and inverters.
It is composed of three parts, and the main components are electronic components.
Constitute. Solar cells can be encapsulated and protected in series to form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices.
Development process. As early as 1839, the French scientist Becqurel discovered that light can make semiconductor materials.
A potential difference is created between different parts.
This phenomenon came to be known as the "photovolt effect", or "photovoltaic effect" for short.
In 1954, American scientists Chabin and Pearson made a practical monocrystalline silicon solar cell for the first time at Bell Labs in the United States, giving birth to a practical photovoltaic power generation technology that converts sunlight energy into electrical energy.
After the 70s of the 20th century, with the development of modern industry, the global energy crisis and air pollution problems have become increasingly prominent, traditional fuel energy is decreasing day by day, and the harm to the environment is becoming increasingly prominent, while about 2 billion people in the world do not have access to normal energy**.
At this time, the world is turning its attention to renewable energy, hoping that renewable energy can change the energy structure of mankind and maintain long-term sustainable development.

As of July 2021, ** is 5,000-20,000 yuan.
The solar photovoltaic power generation system is mainly composed of solar panels, solar controllers, maintenance-free lead-acid batteries and AC/DC inverters as its main components. The core components are the photovoltaic cell pack and the controller.
The function of the solar controller is to control the working state of the whole system, and to play the role of overcharge protection and overdischarge protection for the battery. In places with large temperature differences, qualified controllers should also have the function of temperature compensation. Other additional functions such as light switches and time switches should be optional on the controller.
Advantages: Whether from the perspective of the world or China, conventional energy is very limited. China's primary energy reserves are far below the world average, only about 10% of the world's total reserves. Solar energy is an inexhaustible renewable energy source for mankind.
It has the advantages of full cleanliness, absolute safety, relative extensiveness, reliable long life and maintenance-free, resource adequacy and potential economy, etc., and has an important position in the long-term energy strategy.

Fifth, the initial investment is so expensive, 350,000 yuan can be used for more than 10 years of electricity bills, will it be a loss?
The income of photovoltaic power generation is not only the income of saving electricity bills, but also national subsidies and some local subsidies. According to the mode of self-generation and self-consumption of surplus electricity on the grid, the total income of photovoltaic power generation = saving electricity expenses + excess electricity sales income + national subsidies + local subsidies. In this way, most parts of the country will be able to recover the cost in 5-8 years, bringing 25 years of stable cash flow, and the yield of photovoltaic power generation is still good.
