The degradation of solar photovoltaic (PV) modules is caused by a number of factors that have an impact on their effectiveness, performance, and lifetime. One of the reasons contributing to the decline in solar PV performance is the aging issue.

Why do PV systems have a problem predicting performance?

This equipment and technological diversity contributed to further challenges in accurately predicting the actual performance of PV installations. For example, some PV technologies, such as Cadmium Telluride (CdTe) 13, seem less efficient than silicon-based PV cells.

How many thermal defects do PV installations have?

After thermal inspection, the first PV installation (PV installation #1) was found to have 4377 thermal defects (19.25%), whereas 1872 thermal defects (8.59%) were observed in the second PV installation (PV installation #2). The output energy of both installations was analysed, and the PV degradation was estimated using NREL RdTools 10.

Are thermal defects affecting PV installations' yearly output power?

However, the degradation rate of both PV installations is higher than the UK degradation rate estimated previously by 2, with an average between −0.8%/year or −0.9%/year. This comparison demonstrates the substantial effect of thermal defects on PV installation’s yearly output power.
