This paper reports the analyzing results of the solar energy resource and potential electricity generating capacity from building-integrated photovoltaics (BIPV) systems in Hong Kong. The monthly average daily solar radiation on a horizontal surface and the daily sum distributions of solar radiation show that the solar radiation intensity is quite high in Hong Kong except the wet period from January to March. The mean annual global radiation is 4646.8 MJ/m{sup 2}. The potential electricity generating capacity from BIPV systems is estimated to be 10.5 TWh which is about 35% of the total annual electricity supply (29.9 TWh) in Hong Kong in 1995 if the shadow facades of the high-rise buildings are excluded. The BIPV electricity prices are estimated and compared with the local grid electricity prices. The results illustrate a bright future for BIPV applications in the next century in Hong Kong.
