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. The specific cost depends on the 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!
How much does solar power generation equipment typically cost per square meter?
There are many brands of solar water heaters. Some well-known brands cost between two and three thousand. yuan, even eAbout 5,000, but there are some too. It's a low-key brand, and it only costs a little more than 1,000. I suggest you go to the demolition zone and buy a new solar water heater for two to three hundred yuan.
By August 2021, the price will be 4-5 yuan per meter.
The installation cost of photovoltaic power generation is mainly the cost of equipment, including: photovoltaic modules account for about 49% of the total investment, inverters and other electrical equipment accounts for about 10%, cables and slices each account for about 10%, and different photovoltaic installation companies have their own pricing standards.
Installation capacity varies greatly depending on component capacity and installation angle used. Generally speaking, each kilowatt of photovoltaic power generation system can generate qua3 kilowatt hours of electricity per day and requires an installation area of 10 square meters. If the installation scale is 3-5kW, the investment cost will be about 30,000-50,000 yuan.
Precautions for solar photovoltaic power generation
For photovoltaic power generation systems that operate for a long time, the impact of dust accumulation on the panels cannot be underestimated. The dust on the surface of the panel has the function of reflecting, scattering and absorbing solar radiation, which can reduce the transmission of the sun, causing the panel to receive less solar radiation and reduce the output power. Its effect is proportional to the accumulated thickness. dust.
At the same time, other parts of the photovoltaic panel will also be corroded by wet dust, such as joints, brackets and other parts. Most materials are various types of metals. Corrosion can easily result. damage, weakened security and other problems, which may be damaged by natural factors such as strong winds and earthquakes, thereby reducing the lifespan of photovoltaic panels.
