Estudo de viabilidade para proposição de uma cooperativa solar fotovoltaica para Serra Nordeste do Rio Grande do Sul

Abstract

The generation of electricity from renewable sources is an energy efficiency solution to meet the growing demand for energy in a sustainable way and to diversify the Brazilian energy matrix. Within this context photovoltaic energy has been outstanding in recent years for its modularity and installation that does not generate greenhouse gases and does not cause new environmental impacts, since most of them are installations in urban areas already impacted by man. The present work refers to the study of the implantation, dimensioning and economical viability of a photovoltaic solar cooperative for the generation of energy among twenty-six cooperatives of the northeast sierra of Rio Grande do Sul. A plan of institution for the cooperative in question was elaborated and then collected the individual demands of those interested through the electric bill. After the data were tabulated and the energy division of each partner was established, the sizing of the photovoltaic system was carried out, which resulted in a minigeration and studied the other parameters that encompass the project as an implantation area, civil works and electricity grid, shading. In the results, it was analyzed the efficiency and the estimated energy generation of the cooperative and for each cooperative, in which it implies in a financial feasibility study where each partner, with a different power system, underwent investments in different R$ / Wp . Teh work was finalized with an analysis of the return on capital investment over twenty years for the cooperative in general which resulted in 6.5 years. The time of return of investment for each cooperative that has undergone variations according to the percentage of power generation and invested capital respectively.
