In this paper, the optimal allocation of mega‐solar is examined using data envelopment analysis (DEA). A great deal of attention is paid to photovoltaic power generation in Japan. Because such power generation can be freely used, it is attractive in Japan, which has few natural resources. The allocation of mega‐solar, a large‐scale photovoltaic power generation method, is an important problem for meeting the hope of ecient operation. We tried to apply DEA in Shizuoka Prefecture and to solve this issue. In this type of DEA application, some analyses often result in 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, the above‐stated problems are successfully resolved, and the optimal candidate sites have been selected for the mega‐solar allocation. © 2013 Wiley Periodicals, Inc.
