The Photovoltaic energy represents 1.27% of the power installed in the Brazilian energy matrix: 2.1 GW (BIG, 2019). According to the decennial energy expansion plan 2026, the 2017-2026 it is expected an expansion to the solar-photovoltaic source of 7 GW (EPE, 2018). An increase of 472.97% in installed capacity. This paper discusses the technical and economic feasibility assessment of the use of a photovoltaic solar power generation system, in the mode of remote self-consumption, for a specific consumer of the commercial class. The remote self-consumption modality, created in 2012 by the The Brazilian Electricity Regulatory Agency (ANEEL), allows the consumer to possess more than one consuming unit, within an area served by the same distributor, generate energy in one place, and consume this Energy in other consumer units of the same ownership. A case study was made, in which a system with capacity to meet the electricity consumption of six consumer units was designed. Being the units framed within group B, belonging to the commercial class, the tariffs applied are those approved by ANEEL, subgroup B3. Located in five different cities of Santa Catarina state, the consumer units are serviced by the same distributor: Centrais Elétricas de Santa Catarina (CELESC). The development of the project involved technical and economic aspects, as well as legal aspects, which relate to the distributed generation and the steps to connect the system to the power distribution network of the local concessionaire. When analyzing the sites, some difficulties have arisen with a useful roof area and shading. The project did not become unfeasible by the fact that another option arose during the development of the work. The return on investment for this project is 6.25 years (75 months). Reducing 70.39% of the amount paid in electricity bills by the company, an annual economy of R$ 55,590.60. The system will generate 90.04% of the energy consumed by the six stores for which it was designed.
