PVOP aims at an innovative digitalisation of the PV sector at European scale developing and demonstrating 8 novel technical solutions that will allow to increase the performance of PV systems by 4.7%, reduce the O&M costs by 32% and increase utility-friendly integration with storage. PVOP rationale will be implemented on the basis of operational data record of real PV systems totalling more than 11GW. Advance artificial intelligence and big data methods will be developed to analyse these data together with a deep experience team to establish the cause-effect relationships in system failures. There, on the one hand, these methods will be the core to develop the technical solutions, and on the other hand, open science techniques will help to identify the PV sector needs that will also be considered in such development. The 8 solutions will be validated in 2 phases: 1) controlled environments, and 2) real PV systems. This validation process will be monitored and evaluated with 30 KPIs until TRL 7 is reached. Later on, these 8 technical solutions will be offered to the entire EU PV sector, maximising the impact of the project and making reliable the generation of the expected electricity for longtime. As a consequence of the developments and activities performed in PVOP, the PV sector will have the profitability necessary to meet the EU objectives producing the TWh expected and being leader in the creation of an autonomous and climate-neutral energy system.
