In this paper, mega-solar optimal allocation using DEA (Data Envelopment Analysis) is examined. A great attention is paid to the photovoltaic generation in our country. Such power generation that can be freely used is attractive in our country, which has a little resources. It is an important problem to allocate mega-solar, a large-scale photovoltaic generation, in such a way that we can expect its efficient operation. The authors tried to apply DEA in Shizuoka Prefecture and to solve this issue. In this type of DEA application, some analyst often experiences zero weighting factors in the parameters of some items to be studied, which implies that the corresponding items are not appropriately evaluated. The existing studies do not give special consideration to this situation. In this study a new calculation scheme is proposed and the above stated problems are successfully solved, and the optimal candidate sites have been selected for the mega-solar allocation.
