en.Wedoany.com Reported - The City Council of La Torre d'en Besora, in the province of Castellón, Spain, has expanded the photovoltaic plant on the roof of its municipal multi-purpose building. After the expansion, the system's installed capacity reaches 74.52 kWp, with a rated power of 66 kW. The newly added portion will supply more renewable energy to municipal facilities.

This expansion adds 35.64 kWp of capacity, consisting of 66 modules of 540 Wp each and one 30 kW inverter. The photovoltaic array adopts a coplanar structure, directly fixed to the sloped metal roof, connected to the steel sheets via clamps, longitudinal profiles, and specialized screws. The modules are arranged along the natural slope of the roof without adding extra tilt, maintaining the overall orientation consistent with the building. The City Council stated that the design prioritized the full utilization of the effective roof area and covers the daytime electricity demand of public buildings.

The expansion project also integrates new consumption points into the local distribution grid to optimize the absorption of the generated electricity. The system is expected to increase annual generation by 53,800 kWh, bringing the total generation to 109,330 kWh/year. Currently, the plant powers the town hall, medical clinic, retirement home, school, and multi-purpose venue, with future plans to connect the Carrascal well, Vilás warehouse, weighbridge, and municipal laundry. In terms of energy distribution, the City Council's plan allocates 50% for direct self-consumption and 50% for grid injection. The estimated surplus electricity is 54,600 kWh/year, which can reduce electricity costs by €2,457/year; after deducting operation and maintenance costs, the net benefit is €2,100/year. The physical investment for the project is €21,893.49 (excluding VAT), with a simple payback period of 5.4 years. The project received financial support from IVACE, with a total investment of €25,961.30.
