The rooftop solar park was built by the Spanish contractor AE3000, in the village of Torre-serona, 135 km west of Barcelona. Construction started in 2010 and the initial operation started in February 2011.

The planning of the rooftop panels ensured no shadows are cast by neighboring buildings. The facility uses polycrystalline modules from REC Solar. The Norwegian firm provides a 10-year product guarantee as well as a linear performance guarantee for 25 years. A long-term operations and maintenance plan has also been drawn up. It contains a performance guarantee, obliging AE3000 to ensure the plant availability.

Long-term project financing for the facility was arranged in conjunction with Commerzbank, supported by a low-interest subsidy from the KfW development bank. The funding model allows the payment of annual scheduled dividends, while fulfilling the necessary reserve requirements.
