It depends on where you install it, because the lighting conditions are different in different areas. Assuming your local maximum sunlight period is 6 hours, a 1 kW solar power generation system is typically enough to provide 3 kilowatt hours of electricity per day, or four 250 W solar panels. installed on the ground or on a flat roof, it requires about 10 square meters of installation area; a sloping roof requires approximately 8 square meters. The total cost is around 10,000 yuan.
Overall, it's worth it. From an economic point of view, you will not have to spend money on using electricity in the future. The state will also provide you with subsidies, with a subsidy of 0.42 yuan per kilowatt hour. Some local authorities like Foshan City also provide an additional subsidy of 0.1 yuan. yuan per kilowatt hour. If you have a lot of electricity,you can still sell it to the state, the purchase price of the power supply bureau is not less than 1 yuan per kilowatt hour, which means that 1 kilowatt hour of electricity can be sold. be sold for more than 1.42 yuan. The investment can be recouped in 5 years. Additionally, solar energy is a clean and more environmentally friendly source of energy. Needless to say.
How much does it cost to build a home solar power generation system, is it possible? be used with a 1.5 horsepower air conditioner?
Generally, the configuration is based on the amount of water consumption. The larger the tonnage, the less it is based on tonnage. It is between 10,000 and 20,000 yuan. . It is designed based on many aspects of data, such as how many people are bathing and how many rooms? Is the pipe built above the roof or does it need to penetrate the room? Configuration detailssolar power project, etc., so this quotation is an approximate reference value.
The application type, cost and scale of solar hot water engineering systems in residential buildings should be determined based on the actual building design conditions. The specific plan of the solar water heating project should be determined based on a comprehensive evaluation of economic performance, usage function, system design, architectural design and other aspects of the technical solar water heating system in the building.
I want to install a home solar power system, how big should it be? How much does a set of projects cost?
The current cost of a solar photovoltaic power generation system is about 10,000 yuan per kilowatt.
The air conditioner is less than 2 kilowatts, so in theory there is noNo problem using solar cells. Just reverse it to AC power.
The main problem is that when there is no sun you have to use the energy stored in the battery (also reversed to alternating current).
In this case, you need to buy a lot of batteries. And if you want to have enough electricity to turn on the air conditioner all night, then you need more solar panels to ensure that the battery is fully charged within a few hours during the day and to allow you to turn on the air conditioner during the day. the day. Are you really willing to spend more than 100,000 yuan to do this? Without forgetting the use of lithium batteries.
Conclusion: The technology is mature, but the cost is too high Compared with the electricity price of about 0.5 yuan, there is really no investment value.
Unless you have extremely rich funds or youWe are in an area without a power grid.
Small solar power generation systems are currently only suitable for households in remote areas who cannot connect to the electricity grid and a very small number of wealthy and enthusiastic environmentalists. They are not suitable for ordinary households because it requires too much. a lot of investment and the investment and income It is disproportionate and much more expensive than using electricity from the grid. If you are a successful person who has a strong awareness of environmental protection and energy saving, regardless of costs and benefits, and focuses on social benefits, can use production systems of solar energy. Devices like yours need to build a system capable of producing more than 100 kilowatt hours of electricity per day, and the investment is around 300,000 to 400,000. It costs dtens of thousands to replace the battery every 3 to 4 years.
