Safety, quality and environment pag. 20 | 21 Proener Mantenimiento Fotovoltaico is a company of the Grupo Proener created specifi cally to comply, with maximum quality, with our clients’ requirements as regards the carrying out all the maintenance operations on photovoltaic installations.

The carrying out of turnkey projects on numerous solar photovoltaic energy plants throughout Spanish territory, in Italy and France provides our technical department with excellent conditions for establishing the processes from their initial design until implementation and start-up.

This experience enables us to apply this knowledge to optimise preventive, predictive and corrective maintenance procedures. The trajectory of the Grupo Proener since its start ensures the human and technical resources required for the complete development of the project consultancy and implementation as we rely on the contribution of the group departments (engineering, logistics, electricity, mechanics). SERVICES

We provide maintenance service to installations with a fi xed structure, to installations with trackers, as well as at 6 installations on roofs. Optimisation of the performance of the Ongoing monitoring and operation of the general operating installation, obtaining parameters of the installations: radiation, production, the maximum possible performance. production.
