ALVAREZ-LIMA, Jenifer; LEON-MARTINEZ, Javier A.; MOREJON-MESA, Yanoy  e  PELEGRIN-RODRIGUEZ, Ramón. Feasibility of the Introduction of a Solar Photovoltaic System in a Dairy Agroecosystem. Rev Cie Téc Agr [online]. 2022, vol.31, n.4  Epub 01-Nov-2022. ISSN 2071-0054.

This research is aimed at determining the feasibility of introducing a photovoltaic solar system in 021 Dairy Farm of "El Guayabal" University Farm belonging to the Agrarian University of Havana. The consumption of electrical energy was evaluated and the feasibility of three variants was determined in terms of the number of solar panels (342, 126 and 128) that the photovoltaic solar system must have to satisfy the energy demand. An analysis of the economic and environmental impact of the proposed installation was carried out, which showed that it will allow a saving of electrical energy higher than 43,781.75 kWh/year. With the three variants analyzed, savings were obtained in terms of energy not consumed, avoiding the emission of at least 49.47 t of CO2 into the atmosphere annually, and the consumption of at least 11.47 t of fossil fuel. The preliminary cost to establish the installation proposed was estimated at: 386,255.2 CUP, 419,586.6 CUP and 1,048,290 CUP, according to the variants: without considering the current pumping system, considering the current pumping system and assessing the introduction of the solar pumping system PS2-150 C-SJ5-8, respectively. The energy storage system was not included in any of the variants.
