Maintenance costs

Normally, maintenance costs are very low. The manufacturers ask for a periodic system check and installation cleaning. Typically, the panels are partly cleaned by the rain. In case the installation requires a more frequent cleaning due to extraordinary climatic conditions, it should be done.

As far as the costs of repair and replacement are concerned, generally, the life of a photovoltaic installation is at least 30 years and during this period no reparation or substitution is previewed. Among the main system components, the inverters require substitution about every 10 years.
