Diseño de sistemas energéticos (agrivoltaicos) para el mejoramiento de la producción agrícola de múltiples cultivos en Palora: diseño energético del sistema agrivoltaico.

Abstract

The agrivoltaic system proposed for the improvement of pitahaya production in the town of Sangay, Morona Santiago has a nominal power of 2.43 kWp operating with 405 Wp monocrystalline photovoltaic modules, besides the battery bank is designed with a nominal voltage of 48V array added to a storage capacity of 300 Wh and an inverter with a nominal capacity of 3 kW. In addition, there is diesel generator, which is a backup system, that supplies energy to the array due to the lack of solar resources within the offgrid system. The energy production generated from the proposed energy design is used for artificial night lighting of pitahaya crops with 9W LED lamps that promote the flowering and growing processes of the fruit. Thus, using the parametric method developed in Matlab, the inputs of the AGV system are defined, such as weather conditions, the components’ technical specifications of the energy system and the operational-economic parameters that restrict the behavior of the system under an hourly simulation; in addition, governing functions of solar irradiation, photovoltaic generation, storage and operational strategy, estimated values are defined within the proposed method, with an annual rate of total and specific energy production of 4429.6 kWh and 5008 Wh/kWp per day, respectively. Furthermore, an optimization module is presented that allows to reckon through the objective functions based on the total life cycle cost LCC and the renewable reliability of the system, the best decisional values obtained under a genetic algorithm. Finally, the operating and capital costs of the proposed energy project are defined.
