Investigate the efficiency of a multi-crystalline PV, under real outdoor operating conditions.
- class="label">•
Average PV efficiency is 18% lower than the laboratory STC specifications.
- class="label">•
PV efficiency ranged between 6.2% ÷ 10.4% (annual mean 8.7%) compared to 9.6% ÷ 11.3% under laboratory STC.
- class="label">•
PV temperature is the main parameter negatively affecting PV efficiency (%) and power output drop.
- class="label">•
PV temperature mainly depends on air temperature, solar radiation and less on wind speed.
