Photovoltaic conversion appears as a very promising technology in orde
r to achieve the technical and economic goals for penetration into the
electric energy market. Nevertheless, a serious limit to the very lar
ge diffusion of PV systems is due to the intermittence of solar radiat
ion. Hydrogen produced via water electrolysis can be considered as an
useful means to store solar energy and overcome this limit. With refer
ence to a stand-alone power plant configuration, a PV system, integrat
ed with electrolytic hydrogen production and a fuel cell reconversion
line, is examined in order to check the technical suitability of suppl
ying electricity to a load with time continuity. A mathematical method
, which utilizes as input data the monthly average values of solar ene
rgy density on a horizontal surface is presented, which permits us to
size the PV array as a function of the annual load diagram for a given
solar site. The results demonstrate that PV-H-2 systems are suitable
for realizing a modular stand-alone solar power station able to supply
continuously generic loads.
