Installation steps:
1. Cutting: position and cut a circle on the roof
2. Fixing: fix the aluminum base plate with the roof and make it fit
3. Installation: install the wind turbine body and windproof support bar to fix with the base plate
4. Tighten: adjust the angle of the solar panel, then tighten the screws
