The research activities will be focused on PVperformance enhancement by improved O&M,through the analysis of monitoring data in order toidentify the most relevant effects causingdegradation and reduction in plant performance.

• Cloud-based data management • Data analysis for automated failure detection and diagnosis• Energy production forecast (irradiance and weather prognosis) • Solar economics (impact of degradation and O&M strategies)• Cybersecurity of PV SCADA systems• On-site technical inspections for PV module quality assessment:

Formerly known as Kenergia Sviluppo, istoday the leading independent PV plantsmanagement company operating in Italy,with a portfolio of over 400 MW of PV andwind plants put under control, many withfull Operation and Maintenance services.

• Which key performance indicators (KPIs) must be analysed and how, inorder to study the causes of performance degradation of PV plants?

• Which are the most suitable processes for analysing data sets recorded bymonitoring/SCADA systems?

• How to integrate effectively diagnostic methods into BayWa´s cloud-basedO&M platform for reducing operational costs and production losses?

Theoretical framework

Theoretical study of thedifferent causes ofperformance degradation andpossible solutions during thelifetime of PV systems, as wellas monitoring data analysis.

months 11-13

PV data analysis

Development of suitable dataanalysis processes for theidentification of the relevantparameters out of PV plantmonitoring data sets. A marketresearch of suitable softwarefor analysing big data will becarried out, to see how it canbe integrated into BayWa´sO&M platform.

months 14-19

Case studies

Elaboration of case studies onPV plant performance, to beachieved mainly remotelythrough big data analysis,having access to a hugedatabase of hundreds of PVplants monitored andmaintained by BayWa r.e.Operation Services S.r.l. Fieldtrips to selected PV plants willbe scheduled.

months 20-31

Diagnostic methods

Setup of remote and on-siteeffective diagnostic methodsfor reducing operational costsand production losses based onthe results of the case studies.

months 32-43

New trends and technologies

Market and technical analysisabout new technologies andtheir effectiveness forperformance improvement ofPV systems.

months 44-46
