Resumen
Renewable energy is important in the current context of electricity production, marked
by the search for renewable and increasingly clean sources of energy. The most used renewable
sources, especially solar photovoltaic, in recent years have shown a significant growth in participation
in the Brazilian energy matrix. The realization of this monograph required understanding
the concepts and technologies associated with photovoltaic energy, concepts of economic
and financial viability and legal framework respecting the rules in force in Brazil for this type of
electricity production. After the literature review, the paper presents the technical and economic
evaluation of the solution for the implementation of a photovoltaic generation system at Tecnopampa
Ltda. analyzing if there would be room for system implementation, what is the value
of on-site irradiation, slope and azimuth with best gains, the investment cost, the difference in
the accounts providing the system’s payback calculation of 3.19 years. To analyze the economic
and financial viability of photovoltaic solar energy, discounted payback, net present value, internal
rate of return and equivalent annual value were analyzed. The study used software such
as Excel, for mathematical calculations, Radiasol and Sundata, to obtain climatological data,
HelioScope for orientation and distribution of photovoltaic modules, and for the sizing of the
system, PVsyst was used, which returned a composite system. 114 photovoltaic panels of 114
photovoltaic panels of 325 Wp=each, capable of generating 37:05 kWp, about 95 % of energy
demand. The results revealed that the project of the implementation of photovoltaic solar energy,
at Tecnompampa, as an alternative for cost reduction and energy diversification is viable
for the analyzed period, considering the projected data.
