“…In contrast, if the power were distributed at a ratio of 50 % between the two pumps, neither would not work at low solar irradiance levels, and this would cause an increase in the threshold irradiance for pumping. Carrêlo et al (2020) presented several configurations for large-power PV irrigation systems, some of them similar to those described here and shown in Figure 2. In order to compare the flow rates pumped in the cases described above, the best power distribution strategy in case (b) must be previously investigated.…”

“…Se han realizado varios estudios relevantes sobre instalaciones de sistemas de bombeo de agua fotovoltaica, realizados entre 1981 y 2018 (Carrelo et al, 2020), los cuales mostraron una potencia de entre 0,5 y 3 kWp. Además, hay otras publicaciones que se concentran en el análisis económico de sistemas bombeo de agua fotovoltaica cuya potencia está entre 1 y 8 kWp.…”

Se presenta el dimensionamiento de un sistema de riego aplicado a un cultivo de limón, haciendo uso de la energía solar. Dicho riego cumplió con valores de evapotranspiración potencial (ETP) de 4,31 mm/día y Uso Consuntivo (UC) de 1,85 mm/ha/día, cuya matriz experimental se encuentra compuesta por tres surcos de 57 árboles con requerimiento de 64,91 litros/árbol/día, utilizando goteros de una descarga de 4 litros/hora. El estudio demuestra en un nivel altamente significativo que la humedad se concentra en una profundidad de 15 cm, influenciado por las características físicas arenosas del suelo. Para el requerimiento del agua de riego, se dimensiona un sistema solar, obteniendo un arreglo de diez paneles en serie y dos en paralelo para un total de veinte en conjunto, un inversor de una capacidad de 5,0 kWp, para alimentar una bomba de 2 HP y una vivienda, con consumo promedio de 1,5 kWp, conectado a una red de baja tensión de 220V. La eficiencia global del sistema se registró en el rango de 10 y 14 % y la potencia máxima de salida del sistema fotovoltaico se alcanzó entre las 10 y las 14 horas con un 84 % de la capacidad total instalada (5,2 kWp).

“…The values of PC and EC are determined according to tariff 6.1 in Spain for access power and energy consumption [29], the SuC is calculated for a unit price of 4.69 c€/kWh (the average electricity market price in the last 10 years [30]), t e is 5.11% of 15% of the total costs [31] and DFC is calculated for a unit price of 68.36 c€/L (the average in the last 5 years [32]), considering an average diesel fuel consumption per energy unit of 3.5 kWh/L [26]. Additionally, PC, EC and DFC were updated for an annual inflation rate of 1.7% (the average in the last 10 years in the Euro Area [33]), and PC and EC were also assumed to increase by 3% annually [34].…”

The use of photovoltaic (PV) systems for powering heat pumps (HP) leads to an economic, energy efficient and environmentally friendly alternative for heating and cooling generation. A technical solution developed by the authors permits stand-alone configurations to operate without batteries, mitigating up to 75% of the solar power fluctuations resulting from cloud-passing. Once its technical feasibility has been demonstrated, the economic potential of this innovative solution should be assessed (avoiding a battery system is a significant advantage). This paper presents a comparative economic assessment of this autonomous (AU) solution and a self-consumption (SC) solution, that would substitute a grid-powered HP system for the space heating and cooling of two livestock farms located in Spain. Results show that PV-HP systems are economically feasible regardless of the technical solution: the Profitability Index (PI) is in the 2.23–2.97 €/€ range, the Internal Rate of Return (IRR) is in the 8.1–10.9% range, the Payback Period (PBP) is in the 9.2–11 years range and the savings in terms of the Levelized Cost of Energy (LCOE) are in the 57–70% range. The AU solution offers a higher economic profitability, because it permits larger savings in the electricity bill. The SC solution presents lower LCOEs because of its greater electricity production.
