It is calculated based on the installed capacity.
For example
If you build a home solar power plant, which consumes around 10 kilowatt hours of electricity every day, you can install 4 kW. It will take approximately 3.5 W to install one;
The more kilowatt hours of electricity used, the larger the power plant installed and the more funds will be required.
Explanation of Huayang Green Building-Solar Power Generation.
Which is cheaper: wind power generation or photovoltaic power generation? Wind power is low, wind power costs about 4-5 yuan per watt, and photovoltaic power costs about 7-8 yuan per watt. Low-light photovoltaic panels are cheaper. As photovoltaic power generation technology, especially photovoltaic panels, continues to mature, the application of photovoltaic power generation continues to mature.continues to develop. Photovoltaic power generation is also an emerging industry with good prospects.
Photovoltaic energy production equipment takes up less space and is also suitable for use in cities. Wind power generation equipment should be used in locations with stronger winds, and these locations should be away from large cities.

Advantages and disadvantages of photovoltaic power generation:
1 . photovoltaic power generation
Compared with commonly used thermal power generation systems, the advantages of photovoltaic power generation are mainly reflected in:
①No risk of exhaustion
②Safe; and reliable, no noise, In addition to not emitting pollution, it is absolutely clean (no pollution);
③It is not limited by the regeographic partitioning of resources, and can take advantage of building roofs for example; , areas without electricity and areas with complex terrain;
④Can generate electricity and provide electricity on site without consuming fuel or erecting transmission lines;
⑤High energy quality;
⑥Easy for users to accept emotionally;
⑦ The construction period is short and the time spent on obtaining energy is short.
2. Disadvantages of photovoltaic power generation
① The energy distribution density of irradiation is low, that is, it occupies a huge area
② The energy obtained is the same as that of the four seasons, day and night, and it is related to weather conditions such as cloudy and sunny weather.
③ At present, compared with thermal power generation, the cost of electricity generation is high.
④The manufacturing process of photovoltaic panels is not environmentally friendly.
