An economic analysis of a stand-alone and grid-connected cattle farm

In locations with an average wind speed higher than 7.39 m/s, a stand-alone system is profitable as long as the distance to the grid is higher than 7 km, the price of electricity is 0.192 €/kWh and diesel price is 1.8 €/L. If 800 Ah-battery is used instead of 200 Ah, the COE will be reduced by 18% in location with 7.39 m/s average wind speed.
