The one I installed comes from Hanergy. It costs 45,000 for 5 kilowatts. In winter, the electricity produced is around 15 degrees per day, and in summer it is around 25 degrees. One kilowatt hour of electricity costs 0.85 yuan. which is only 6,000 to 7,000 degrees per year.
I heard that there will be no state subsidies in 2020. Installing a photovoltaic plant is a huge waste, it's a scam, don't install it. What a cheat. The propaganda will pay off in 5 years. Hell, it won't pay off in 10 years.
The first two are wind power plants
The difference is that the dual-powered motor rotates at a very high speed (1500), while the blades rotate at a low speed, so a gearbox is required for speed change
The characteristic of permanent magnet direct drive is that the motor rotates at low speed and is directly driven by the pales, but the converter system is a little more complicated
The third is solar power generation
In addition to wind power generation, they both can produce electricity and there should be nothing in common. . . .
The final energy storage consists of rechargeable batteries. . .
