The following study aims to evaluate the proposal of a solar photovoltaic system with a view to reducing energy consumption in a hatchery. The proposed system is composed of 3 strings of 18 modules connected in series of the DSM-380MP type occupying a useful area of 105 m2. The photovoltaic solar system is accompanied by an inverter model TRIO-20_0-TL-OUTD-S1-US from ABB with an output of 22 kWac. The solar photovoltaic system has an annual generation capacity of 29,068 MWh/year. Since the plant has an annual generation capacity of 29,068 MWh/year average annual consumption for the case study is about 100 MWh/year, it is possible to substitute approximately 30% of this consumption by using the FVSS. Considering one of the minimum costs of the international market for the FVSS of 32 060,45 $CUP, the investment presents a NPV of $ 741 728,91, after 25 years, an Investment Recovery Period (...

Multi-criteria methods are highly attractive tools to address the inherent complexity of evaluating problems in various scientific areas. The combination of methods such as Delphi/AHP is emerging as a robust alternative to evaluate the sustainability of renewable energy sources. In this theoretical-descriptive research, the use of the Delphi method is proposed to select criteria and sub-criteria to obtain a high level of reliability, while the AHP method is used to establish an order of preference among the alternatives analyzed. This process requires the support of a committee of experts, whose role is to identify the various biomass alternatives that can be used in the sugar industry, considering aspects related to sustainability. The selected experts have identified energy, exergy, and emergetic indicators, in which economic, environmental, and social aspects are integrated. The multi...
