FAQ 1. What kind of region can be installed wind turbine?Small wind turbines should be applied in the regions which wind resources is sufficient. The annual average wind speed should bemore than 3m/s, the effective wind speed 3-20m/s should be more than 3000h in accumulation per year. The density of 3-20m/seffectively average wind power should be more than 100W/m2.It should be noted that choosing the rated design speed wind turbine is in conformity with local design speed. It is significantlyin making use of wind resources and in economic aspect. Wind tunnel test proves that the fan power transformation of the impellerin the direct ratio with wind speed, that is to say, the wind speed decide the output electrical power.2. How to calculate the actual need power in my home to configure the appropriate power of wind turbines?At present, battery stores the power from the wind turbine, then discharge to home appliances. So the power which discharged tothe load and be charged timely by wind turbine is the amount of the actual needs power.Take an example: the rated output power from wind turbine generator is 100W per hour, the continuous workable hours by wind is 4hours. The battery can be charged total capacity is 400WH. For only about 70% power from battery can be discharged to the load, sothe actual power which can be used from battery is 280WH.If there are:1) Bulb15W x 2 Pieces, working 4 hours one day, consumption 120WH2) TV 35W x 1 set, working 3 hours one day, consumption 105WH3) Radio 15W x 1 Piece, working 4 hours one day, consumption 60WHAbove total consumption is 285WH per day. If you only design to install 100W wind turbine generator, the consumption total powerwill more than the power from wind turbine generator. In long period of time using power from 100W wind turbine generator, it willmake the battery serious loss of electricity and damaged, and it will cut down your battery service life.It is assumed that wind turbine at rated wind power generation and energy consumption, but in fact, due to the variability of thewind, intermittent, there are strong and weak wind different (wind speed) and wind blow in long time and short timedifferent(frequency). So you should cut down even cut off some electrical application working time when the wind condition is inpoor to protect your battery. If your budget is enough, it will be better to install a diesel generator set or install solarpanels at the same time.3. How to select the correct battery capacity to get power from wind turbine generator?Generally, the battery capacity should be equal or smaller than the power from wind turbine generator.1) 100W wind turbine generator matches 120AH battery (60AH x 2 Pieces)2) 200W wind turbine generator matches 120-180AH battery (60 OR 90AH x 2 Pieces)3) 300W wind turbine generator matches 240AH battery (120AH x 2 Pieces)4) 750W wind turbine generator matches 240AH battery (120AH x 2 Pieces)5) 1000W wind turbine generator matches 360AH battery (60AH x 3 Pieces)
