With the high costs of electric power in large enterprises such as shopping malls, entrepreneurs seek a reduction in energy costs. Due to increasingly affordable prices, government incentives and federal laws, the implementation of microgeneration projects and the minigeration of electric energy through solar energy have the capacity today to achieve objectives not only in favor of the environment but also objectives financial resources. The present work has the purpose of dimensioning and analyzing the feasibility for the implementation of photovoltaic (PV) generation in a shopping center in Fortaleza - CE. After the theoretical concepts, the area available for implementation of the PV project is determined and a shading study is carried out, with the help of the SketchUP program, in order to have the useful area for the project, it was adopted that 90% of this area would be used for installation of the modules, considering a spacing between the PV modules for future maintenance, resulting in 3188.11 m2. Based on the usable area and the consumption demand data of the mall, 5500 kW, the project design is developed. A comparison between four types of solar panels is proposed and, finally, a financial analysis is done with the help of the RETScreen4 program, considering the life of the 25-year PV modules for all alternatives. The time of return of the investment is presented for each alternative, thus concluding the viability of the project. Of the 4 alternatives studied, the CdTe plate presented the worst payback, at 8 years and 8 months, and lower NPV, of R $ 2,214,785; the p-Si plate presented the best payback, but the m-Si plate presented the highest NPV of R $ 6,809,107, making it the best alternative.
