Abstract
Photovoltaic (PV) cells are considered as one of countermeasures for saving electricity generated by fossil fuels. When PV cells are largely introduced in Tokyo, the surface heat valance will be changed. We developed a new PV cell surface heat balance model so as to assess all the impacts of introduction of photovoltaic cells, like a change of energy consumption resulting from a change of air temperature and a change of cooling loads in buildings resulting from the shielding effect ofphotovoltaic cells.
We set PV cells on the top of the roof of a research institute building in Tsukuba, Japan, and measured PV cell surface heat valance and meteorological data. From these measured data, we determined our model's parameters.
