| Work Detail |
The Mayor’s Office of Castillo de Locubín City Council in Jaén has launched a tender for the execution and commissioning of a 160 kW photovoltaic project aimed at enhancing water collection and pumping from the San Juan River. This initiative represents a significant step towards sustainable energy use in the region.
The solar plant will be situated approximately 575 meters from the CBT on farmland previously planted with olive trees, now lying fallow. The total budget for the project is 260,876 euros, with the deadline for submitting offers set for June 25. The project has an execution period of three months.
Upon completion, the project is estimated to consume 294,802.47 kWh annually. With a budget of 260,876 euros and assuming an energy cost of €0.18 per kWh, the return on investment is projected to occur within five years.
The project will employ 560 W solar panels from Chinese manufacturer JA Solar, totaling 190,400 kW in capacity. Each panel measures 1.134 m x 2.278 m with an open circuit voltage of 50.15 V. The panels will be arranged in series of 13 and 11, achieving a voltage of 651.95 V per series. The system’s industrial wiring will have a continuous current rating of 1.5 kV with MC44 type connectors.
The installation will feature four inverters, rated at either 25 kW or 20 kW, each with four DC inputs. The 25 kW inverters will connect to series of 13 panels, while the 20 kW inverters will connect to chains of 11 panels. These inverters will be housed in prefabricated niches, with LV underground lines running to the General Control and Protection Panel equipped with busbars, magneto-thermal and differential protections, and a 250 A IGM.
The chosen site for the solar plant features an 18% slope facing 10º south and a 23% slope facing 13º west. A lane will be constructed along the western part of the property. The double-panel metal frames from Valencian brand Sunfer will be installed vertically with a 10º inclination towards the south.
The tender document states, “The object of the contract consists of the execution of the 160 kW photovoltaic self-consumption installation for collecting and pumping water from the Source of the San Juan River.”
The project is financed under the Recovery, Transformation, and Resilience Plan, reinforcing the commitment to sustainable and renewable energy solutions in the region. |
