Power quality issues The output of solar PV is highly intermittent due to its dependency on irradiance, temperature, and atmospheric conditions. This enhances PQ disturbances when integrated with a grid which needs to be mitigated to ensure stability and smooth synchronization.
T he economic and societal impact of photovoltaics (PV) is enormous and will continue to grow rapidly. To achieve the 1.5 °C by 2050 scenario, the International Renewable Energy Agency predicts that PV has to increase 15-fold and account for half of all electricity generation (15 TW), increasing from just under 1 TW in 2021 .
This limitation is particularly critical in the context of photovoltaic (PV) cell defect detection, where accurate detection requires resolving small-scale target information loss and suppressing noise interference.
These defects can substantially degrade the power output of the cells 2, 3. Among these, cracking defects are particularly critical, being recognized as one of the predominant contributors to power loss in photovoltaic modules.
When solar PV sources are integrated to the AC grid to enhance reliability, pose PQ challenges due to the intermittency nature of the solar and the low strength of the rural grid , , , , , , , , , , , .
The degradation of photovoltaic (PV) systems is one of the key factors to address in order to reduce the cost of the electricity produced by increasing the operational lifetime of PV systems. To reduce the degradation, it is imperative to know the degradation and failure phenomena.
