A 5 kW household can be installed on a 100 square meter roofPhotovoltaic power plantThe price of photovoltaic systems on the market is 7 to 9 yuan per watt, which means that it will cost 3.5 yuan to install 5 kW - 45,000 yuan.
The prices of photovoltaic power generation equipment are different and the materials are different. There is monocrystalline silicon and polycrystalline silicon. Prices are different from polycrystalline silicon and have higher power. generation efficiency.
Note:
Nationally, the cost of solar photovoltaic power generation is 8-12 yuan per watt. For example, a 100 square meter roof can produce 10 kilowatts. Calculated at 10 yuan per watt, the final total package price is 100,000 yuan. This price includes design, equipment, construction and connection to the network, etc. The specific price ofmust still be determined based on demand and installed capacity.
Hello, the installation cost of a 10 kW photovoltaic power plant in 2021 is about 50,000 yuan. In some places it will cost less than 50,000 yuan. local average installation price.
The annual electricity production of a 10 KW photovoltaic plant varies depending on the region. For example, the power generation coefficient in Zhejiang is about 1.15, so the annual electricity output of a 10KW photovoltaic power plant is about 10,000*. 1.15 = 11,500 degrees Assuming the weather is roughly the same throughout the year, the average daily electricity production is around 31 degrees.
I hope this can help you!
