Abstract
The present study aims at the use of photovoltaic solar energy in the Northeast region, more precisely in the city of Fortaleza. The study includes the analysis of the insertion of photovoltaic plants in homes in Fortaleza and its economic viability due to the new conditions created after the year 2020. from 2023. Thus, three photovoltaic systems for the generation of electricity at a residential level were studied, with different powers, but within the most used ranges in the residential sector of Fortaleza. Each plant took into account three types of analysis, with the acquired right, with the taxation of 100% of wire B and for the current scenario, taking into account the escalation of the charge for wire B, which starts at 15%, in 2023, and it increases linearly until it reaches 100% in 2029. We took into account the customer who obtained the system through cash payment or financing. An economic feasibility study was carried out, in which an inflation of 5.79% p.a. was used, and a tariff readjustment of 11.35% p.a. in the three plants, taking into account a sensitivity analysis of this variable. It is noteworthy that the study presented in this work determined that Law 14300/2022 that came into force does not make the investment unfeasible, since comparing the scenarios before and after (for cash payment) the difference in the investment return time was in an average of 1 year and 6 months for the three plants. For comparison purposes, the ±7% variation in inflation affects the payback to a greater extent than the update of the FIO B charge.
