en.Wedoany.com Reported - The first privately invested collective self-consumption photovoltaic project in the Autonomous Community of Navarre, Spain, has been launched in the El Parral industrial estate in the municipality of Cáseda.
"The first privately funded collective self-consumption project in Navarre has been launched in the El Parral industrial estate in Cáseda," Mikel Abáigar, Operations Director at M&A Energy Consulting, told pv magazine. "This initiative originated from a resident of the municipality who decided to use the roof of his industrial warehouse to provide shared solar energy to local businesses that cannot install photovoltaic panels due to structural or space limitations," Abáigar added.
The installation is located on the roof of the industrial warehouse of Electrodomésticos García, occupying an effective area of 297 square meters. It uses the Gulpiyuri 30-rail coplanar structure from the Asturian brand Alusin Solar, adapted for a gable roof with a 10-degree inclination and a south-north orientation (202° and 22°, respectively). The system integrates 110 modules of 640 Wp from Chinese manufacturer JinkoSolar, along with an inverter from the Chinese brand SAJ, model R6-50K-T4-32, reaching a peak power of 70.40 kWp.
The estimated annual energy generation is 94.137 MWh, with a specific yield of 1.337 kWh/kWp and a self-consumption rate of 97%. Energy is dynamically distributed through the Elecsum Shearing platform, allocating the generated power to ten businesses located within a two-kilometer radius of the installation. The project manager noted a technical challenge faced during development: due to supply chain delays, the originally planned 595 Wp module model was replaced with the 640 Wp version. "After confirming compatibility provided by the Alusin Solar team, the replacement was completed without modifying the structural design."
Several companies participated in the project's implementation: Valencia-based Saclima handled the supply of photovoltaic modules; Sonne PV, a Valencian company with operations in Spain and Portugal, provided the inverter; Catalan company Elecsum Shearing managed the collective self-consumption and dynamic energy distribution; the system's technical design was carried out by Navarre-based company ATB Ingeniería; and construction was undertaken by Marsan Solar, a Navarre company specializing in industrial photovoltaic installations. Ten businesses from different sectors—including a glove factory, a kitchen furniture manufacturer, an adhesive label company, two restaurants, four bars, and an appliance store—directly benefit from the system, "enjoying discounts on their electricity bills without needing to make their own investment," Abáigar concluded.
