en.Wedoany.com Reported - King Juan Carlos University (Community of Madrid) has launched a tender for the construction of a grid-connected self-consumption photovoltaic power station on the rooftops and carports of its Móstoles campus, which will not feed electricity into the grid.
The contract budget for this project is 1.48 million euros, with a bid submission deadline of June 15. The construction period is ten months, and the tender will follow an open procedure with ordinary processing. The planned installed capacity of the power station is 730.24 kWp (peak power) and 650 kW (AC power), intended to meet the campus's individual self-consumption needs, with the generated electricity connected to the campus internal grid. In 2025, the campus's electricity consumption was 4,112 MWh, with electricity costs of approximately 725,000 euros.
The photovoltaic system will consist of 1,304 monocrystalline silicon photovoltaic modules, each with a power output of 560 Wp, achieving a total peak power of 730.24 kWp. The modules will be installed using coplanar tilt structures on multiple rooftops and on carports in two parking areas. Direct current will be converted to alternating current by six 100 kW inverters and one 50 kW inverter before being injected into the low-voltage grid. The estimated annual electricity generation of the project is approximately 1,127 MWh, with expected annual electricity cost savings of nearly 170,000 euros. This calculation was performed using PVSyst software, taking into account the tilt and azimuth angles of each area, adjacent shading factors, and an estimated total horizontal irradiance of 1,750 kWh/m².
A photovoltaic carport will be planned on the west side of the campus, providing 600 kW of generation capacity while also offering shade for the currently exposed parking area. The second installation area is located on the rooftop of the Departamental I building, near the connection point, where a 50 kW inverter will be installed. This project does not receive funding from the European Union.
