PROBLEM TO BE SOLVED: To provide an evaluation system of solar energy generation capable of efficiently and adequately estimating an activity for solar energy generation in a city, and a method for estimating solar energy generation. SOLUTION: This evaluation system of solar energy generation comprises a local area designation means 3 for designating an estimation target area 2 from map data 1 of GIS, a sunlight reception area computation section 5 that provisionally computes a sunlight reception area of each of a plurality of estimation target buildings 4 which are arbitrarily set in the estimation target area 2 on the basis of a positional relationship between a three-dimensional cubic model of the GIS and a solar position, and a shade interference area computation section 6 that provisionally computes a shaded area which is formed on the sunlight reception area 4a of each of the estimation target buildings 4 by any other estimation target building 4' on the basis of sunlight simulation applied to the three-dimensional cubic model. The evaluation system further comprises a power generation estimation means 7 that provisionally computes a total solar energy generation amount of the entirety of the estimation target area 2 in such a manner that an individual solar energy generation amount of each of the estimation target buildings 4 is obtained by multiplying a power generation coefficient set to the estimation target area 2 to a difference between the sunlight reception area and the shaded area, and the individual solar energy generation amounts of the plurality of the estimation target buildings 4 in the estimation target area 2 are totalized.
