The electric power generation from solar powered house has tend to excess the electric consumption. This study focuses on maximizing simultaneous power consumption at grid-connected solar powered energy efficiency house from the aspect of self-consumed power. In order to evaluate the simultaneously consumption, the absolute values of the sum total of plus and minus grid power is calculated using our prototype solar powered energy efficiency house’s instantaneous measurement value for every minute of electrical power flows data. From the result, the minimum dependency of grid power and optimum install photovoltaic power capacity with the maximum simultaneous power consumption are estimated.
