General household photovoltaic power generation costs about 10 yuan per watt, and 3 kW is equivalent to 30,000 yuan including installation costs. Set aside 10,000 to 20,000 to avoid damage to batteries, solar panels and other hardware during use. Assuming that PV power generation can be used for 20 years and the cost is 45,000, you can simply calculate how much electricity your house consumes each month.
On average, 45,000÷20÷12=187.5
That is, about 187.5 yuan per month (this has a lot to do with the quality hardware such as panels and batteries, and the entire photovoltaic system (the lifespan of the power generation system also has a big relationship
So if you can use 187). yuan of electricity per month, you can install it. If you can't use it, there is no need to install it.s, the lifespan is usually more than 20 years, probably 25-30 years, so you won't save much money. If your home doesn't use a lot of electricity, this isn't necessary.
The benefits of clean, non-polluting and inexpensive solar energy are obvious. As long as the surface area of the solar panel is large enough to power a 3000 watt motor, there will be no problem. The problem is that its power output is unstable. Therefore, changes in the power supplied to the motor will affect the power output of the motor. The engine sometimes speeds up and sometimes slows down. For reference only thanks.
