1 Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art European PV Solar Energy Conference and Exhibition, September 2015, Hamburg, Germany Jonathan Leloux Rodrigo Moretón Luis Narvarte Jamie Taylor David Trebosc Adrien Desportes Instituto de Energía Solar Universidad Politécnica de Madrid, Spain Sheffield Solar University of Sheffield, UK BDPV, France Rtone, France

2 Objective: ask questions and get answers from the data Energy yield? Overall performance? Differences? Key factors? Best PV cell technologies? Improvement in state of the art? PV modules/systems degradation? Do we observe faults? Effects of the policymaker? Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

3 Data from PV systems INPUT DATA Data PV systems characteristics Energy production Solar irradiation (GTI) Source PV system installer or owner Energy meter or inverter Synermet Country Nb PV systems Peak power [MWp] Type France Rooftop Belgium Rooftop UK Rooftop Spain PV plant Rest of Europe Rooftop TOTAL Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

4 The peak power of most of the PV systems is < 5 kwp Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

5 France: peak power limited to 3 kwp by public incentives Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

6 Belgium: peak power shaped by net-balance incentives Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

7 The annual energy yield greatly varies geographically Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

8 Annual energy yield of PV plants in Spain and tracking Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

9 The yearly PR follows a Weibull distribution Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

10 The data follow a Weibull distribution for 0.6 < PR < 0.9 Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

11 The mean yearly PR in Europe lies within Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

12 Mean yearly PR France: 2-3% lower than other countries Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

13 The small PV systems have a lower PR Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

14 Difference in PR between inverters: 1-5 % Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

15 Difference in PR between modules (no thin-film): 1-6% Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

16 PV modules technology greatly affects performance Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

17 PV systems performance has improved over time Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

18 PV systems performance degradation over time is low Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

19 Some PV systems are clearly subject to faults Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,

20 The monthly PR is influenced by several parameters Monitoring 30,000 PV systems in Europe: Performance, faults, and state of the art, PVSEC, Hamburg,
