More than ten million. CCTV once reported that a medium-sized one can generate 5 degrees of electricity without turning once, and it can turn once every 5 seconds during a stroke (one turn every 4 seconds in strong winds). It can turn 12 times in one hour, and 720 times in one hour. 720×5 degrees=3600 degrees/less hours×0.5 yuan/degree×24 hours=43200 yuan/day×300 days=12.96 million yuan/year.
The current price of wind power equipment is generally around 900,000 euros/MW, or RMB 7.61 million. 4 million can buy 0.5 MW wind power equipment. The price of a 300KWwind turbineis about 3.2 million yuan, and there are currently 0.5-2.0 MW wind power equipment on the market.
A wind turbine is an electrical device that converts wind energy into mechanical work. The mechanical work drives the rotor to rotate and ultimately outputs alternating current.
As for the price, it depends on which brand you choose, how much power it has, what configuration it has, etc. At present, wind power equipment is generally around 900,000 euros/MW, or RMB 7.61 million. 4 million can buy 0.5 MW wind power equipment.
