One of the most interesting energy development systems is the one based on hydrogen use and their integration with renewable energy sources. In fact, hydrogen can operate as a storage and carrying medium of these primary sources. An analytical model to size, analyze and assess the feasibility of a hybrid photovoltaic/hydrogen (PV/H 2 ) energy conversion system using real weather data is presented in this work. The analysis considers an energy balance and electrical variables of the system components; the sub-systems efficacy are calculated and proposed the improvements to increase the efficiency, using surplus energy produced by hybrid system. Solar radiation measurements was gotten from a meteorological monitoring station which is placed in the roof of the sustainable house and located in Mexico City north side. The PV/H 2 system delivered electric power from a primary source (PV) to feed the electric load and surplus energy is supplied to electrolyzer in order to generate hydrogen, while energy deficit hours a PEMFC covers part the electric demand. Therefore, the hybrid system efficacy is calculated by energy stored level and electric load required. [ABSTRACT FROM AUTHOR]
