Monitoramento e verificação de sistemas fotovoltaicos: análise técnica e econômica

Abstract

Searching for alternatives to the high increase in demand and electricity tariffs, electricity generation through photovoltaic systems has been considered a good alternative worldwide. Photovoltaic systems have been considerably growing in Brazil, becoming one of the most promising sources of electricity generation in the country. The research proposed in this work aims to propose a simplified Monitoring & Verification (M&V) methodology applied to grid-connected photovoltaic systems. The results obtained from the technical analysis indicated a monitored electricity generation close to that predicted in the project. The resulting difference between projected and monitored electricity generation was approximately 2%. For the three feasibility indicators estimated, the analysis of the project proved to be attractive, since the discounted payback, for both the predicted and monitored savings, was approximately 5 years; the IRR of the predicted and monitored savings is greater than the minimum attractiveness rate and the NPV of the forecasted economy and monitored economy is positive.
