Calculated based on actual watts.
The cost of solar energy production is calculated at 3.2 yuan per watt.
A solar power plant refers to a power plant that uses solar energy to produce electricity, including solar power generation and solar thermal power generation.

First of all, we need to know what equipment is needed for the grid-connected photovoltaic power generation system.
The hardware of solar power generation system mainly includes photovoltaic components, grid-connected inverters, cables, brackets, monitoring equipment, etc. The market price of photovoltaic modules is generally 4 yuan per watt. Therefore, the installation cost of a 5 kW solar power generation system is about 40,000-60,000 yuans.
How much does solar power generation cost?
Solar power generation is an environmentally friendly and renewable energy source that is increasingly attracting More attention. Using solar energy systems in your home can save you money on your energy bills while reducing environmental pollution. This article will discuss the costs and benefits of home solar energy systems, as well as operating procedures and precautions.
Costs and benefits of domestic solar power generation systems
The cost of solar power generation systems mainly includes the cost of solar panels, inverters, batteries, cables and other equipment, as well as the cost of installation, maintenance, etc. Prices vary depending on the size and quality of the system. Currently, the price of a home solar power system ranges from 50000 to 200,000 euros.
Although the price of home solar power generation system is higher, its advantages are also obvious. First of all, solar energy is a renewable energy source that will not run out like fossil fuels. Second, solar energy production does not produce pollutants and has no negative impact on the environment. Finally, solar energy can help households save on their energy bills, which can lead to significant savings in the long term.
Operation steps
1. Choose a suitable solar power generation system. Choose the right solar power system based on your home's power consumption and needs.
2. Install solar panels. Solar panels should be installed in a sunny location, such as a roof or terrace. When installing, you must pay attention to the orientation andto the tilt angle of the battery panel.
3. Install the inverter and battery. An inverter is a device that converts direct current generated by solar panels into alternating current, and batteries are used to store the electrical energy.
4. Connect the wires. Connect solar panels, inverters and batteries to form a complete solar energy system.
5. Perform debugging and maintenance. After installation is completed, debugging is required to ensure normal system operation. The system also needs to be maintained and serviced regularly to ensure its long-term stable operation.
Remarks
1. Proper planning and preparation is necessary prior to installation to ensure proper operation of the system.
2. Pay attention to safety during installation to avoid accidents.
3. The system must be maintained rregularly.care and maintenance to ensure its long-term stable operation.
The overall cost of a small-scale solar photovoltaic power generation system for offices is about 10,000 yuan per kilowatt. You consume 8 kilowatt hours (kWh) of electricity per hour and theoretically need around 10 kilowatts of photovoltaic power generation facilities (due to efficiency issues). It will cost around 100,000 yuan.
But the real situation is much more complicated than that. You need continuous power supply 24 hours a day, and even large-scale professional solar photovoltaic power plants in China can only produce electricity for about 2,000 hours a year. . That is to say, on average, it can only efficiently produce electricity for about 5.4 hours a day, which can only cover about one-fifth of the electricity you need.ur 24 hours. In other words, 10 kilowatt power generation equipment is sufficient. far from meeting your needs. Based on this calculation, you need to purchase and install 50 kilowatts of photovoltaic power generation facilities, as well as a battery sufficient to store 40 kilowatts of electricity for 19 hours. Otherwise, electricity cannot be supplied at night and other times when there is no sunlight.
The cost is at least 600,000 yuan. The battery also takes up one of your rooms.
Regarding the investment payback period, if it is calculated based on the electricity price of 0.93 yuan and based on static calculation, it will take about 10 years. If calculated dynamically, that is, taking into account the time value of your one-time investment of 600,000 yuan (similar to interest of at least 6%), the cost recovery time will be prolonaged from about 3 years old, to about 13 years old. .
In addition, if it rains or snows for several days in a row, the solar power generation system will hardly be able to produce electricity, and you will also have to use the energy from the large intermittent electricity network. .
In addition, the electricity generation capacity of photovoltaic solar panels will continue to decline. After 5 years it would be good to maintain 90%. This factor will cause your power supply capacity to decrease. Additionally, battery life is very limited (unless you purchase expensive imported batteries) and the battery needs to be replaced approximately every 3 years, further extending your cost recovery period.
Let’s analyze it. Although it is eco-friendly and appears to be high-tech, the reliability of solar power supply cannot be complimented and the payback periodn is too long.
