Resumo
The present work presents cost analyzes for the
implementation of photovoltaic systems systems connected to the
network, in order to supply 50%, 75% and 100% of the
consumption of a popular house, previously installed directly
connected to the network, in the city of Ipanguaçu RN. The
system's methodology consisted of the same adopted by the
Reference Center for Solar and Wind Energy Salvo Brito
(CRESESB), as well as taking into account the standards
established by NBR 5420 and ANEEL Normative Resolution
687/2015. It was taken into account that over the years there were
losses in the system, as well as the variation in the tariff charged
by the local concessionaire (COSERN). The main objective of
verifying the economic feasibility of supplying a load previously
installed, in order to dimension and choose the components of the
system, in order to estimate the total value so that after this phase,
it will show the return time of the initial investment, where this
time obtained it was satisfactory for being a short period of time,
somewhere between the fourth and fifth year after its installation.
It was possible to obtain, respectively, the following returns of R $
1466.29, R $ 2052.81 and R $ 2639.33 in the first year of generation,
a return that grows over the years, even though the generation
decreased due to losses, however the corrected tariff of the
concessionaire reaching as high as R $ 0.90 between the fourteenth
and fifteenth year after the installation of the system.
