The area of 18 acres of land is 18*666=11988, which is approximately 12,000 square meters. According to the geographical location of Dezhou, Shandong, the installation angle is 34 degrees, and 580 kW can be actually installed. Electricity production in the first year is approximately 720,000 kWh. The average annual electricity production over 25 years is 590,000 kWh per installation. The total investment of a ground-mounted power plant worth 8 yuan per watt is 580*1000*8=4.64 million. /p>
The first is the question of how big the system can be installed. Each square meter can install about 100 watts, and 300 square meters can install about 30 kilowatts. Rizhao Normally it can generate around 100 kilowatt hours. of electricity every day, or 3,000 kilowatt hours per month, which is completely sufficient. Then there is the question of investment cost, which is around 250,000 to 300,000.This system is connected to the grid, so don't worry about electricity. . The problem of not being able to afford it.
