Technological modernization interventions for photovoltaic systems can be divided intotwo macro-groups:

1. Repowering: non-incentivised upgrades which concern modules, inverters, panels, and canconcern cabins and also anchoring structures, transforming the systems from fixed to mobile.

2. Revamping: as above, but reasoning with the same nominal power or with no overpowering greater than 1% of the pre-intervention nominal power as set out in the DTR – Document technical reference for technological modernization interventions published by the GSE in April 2023 – Procedures pursuant to the Ministerial Decree June 23, 2016.

In principle, technological modernization interventions are carried out on systems that have not been in operation for at least 7/10 years by replacing the photovoltaic modules and the components making up the conversion group affected by various problems.
