How many roof turbines do I need?
Each roof turbine has a minimum power rating of approximately 300 kilowatts of electricity. That power output is required to operate all the air conditioning and refrigeration in a 6,700-square-foot house. A 150 KW solar photovoltaic (PV) system will provide that power if the weather cooperates and the solar panel has sufficient sunlight to generate electricity. Therefore, it is best to use 2 or 3 roof mounted turbines to provide that amount of electricity.
