MRP assisted Repower Renewable (Repower Group) as technical advisor in the photovoltaic revamping and repowering of 13 PV systems in Italy for a total power of over 23 MWp.
The contract assignment is divided into 3 distinct phases, which involved the various MRP teams:
The analysis of Repower’s plants identified the interventions to be carried out, with a preliminary assessment of the costs / benefits and the technical feasibility for:
In particular, thanks to over 20 years experience in the sector, MRP’s activity was focused on the validation tests of the technology to choose for the revamping and repowering, with the selection of different suppliers and technologies of modules and inverters through measurements and active monitoring in the field.
The subsequent study of the structures and the evaluation of different system configurations made it possible to optimize the interventions to be performed, considering the following parameters:
Upon arrival of the modules at the plants sites, the MRP specialists carried out the inspections according to the internal procedures for acceptance. Once the module and inverter replacement interventions were completed, the MRP verification team performed the analysis with EL electroluminescence technique on 100% of the installed modules, allowing to identify:
A point from scratch of the systems was thus obtained, with a complete and updated situation of the real operating status of the DC side of the interventions performed, also essential for any future diagnosis of the system or damage from hail or atmospheric events.
