Give examples of solar energy building applications (the more the better), thank you!

Solar energy: solar water heater, solar street lamp, flashlight, etc. They are all commonly used in our family, and there are also household lighting (not used much, mainly because it is too expensive, and the economic benefits may not be very good. I remember that if the power of a lamp is15w, then the cost of one watt is 25 yuan, that is, the lamp cost of15w is 375 yuan).

There is a solar photovoltaic power station on the roof of the market in the fourth district of Yiwu International Trade City, China, with a total area of1.4000 square meters. More than 7,000 crystalline silicon photovoltaic panels are divided into eight areas, which continuously absorb heat and transmit electricity every day. On February 26, 20 1 1, the photovoltaic power station was officially connected to the grid for power generation, with an average daily power generation of more than 4,200 kwh, which is mainly used for lighting in public areas such as market passages, and most of the power required by central air conditioners comes from this.

This is a "green roof". According to technical calculation, this solar photovoltaic power generation system can generate 38 million kWh of electricity within its service life. Compared with thermal power generation, it is equivalent to saving nearly 6.5438+0.5 million tons of standard coal, reducing carbon dioxide emissions by 38,000 tons, reducing sulfur dioxide by about 359 tons, and reducing a lot of nitrogen oxides and dust. It can be called a leading model of developing "low-carbon economy" in Yiwu. I am from Yiwu, too. )
