AI Customer ServiceThe performance of a photovoltaic (PV) system is highly affected by different types of power losses which are incurred by electrical equipment or altering weather conditions. In this context, an accurate analysis of power losses for a PV system is of significant importance.
Through the elimination of loss factors in the photovoltaic systems, these losses must be minimized. Factors that may cause SPV system losses include environmental factors such as wind, dust, snow, heat, temperature, and other losses caused by device components such as cables, inverters, and batteries.
Furthermore, the detailed PV array losses were classified as mismatch power losses, dust accumulation losses, temperature effects, material quality losses, and ohmic wiring losses. The unavoidable system losses were quantified as inverter losses, maximum power point tracking losses, battery losses, and polarization losses.
System-Level Losses On a system level, the inverter losses, batter losses, maximum power point tracking (MPPT) topology losses, and potential-induced degradation or polarization losses are among the major types of PV system losses that result in reduced PV system performance over time [24, 25].
In addition, the possibility to know the current amounts of losses and have available an estimation of the future values of these losses can help the PV system owners to have a clear perspective on the long-term operation of the system and plan for maintenance or other solutions.
Performance metrics such as performance ratio and efficiency have been widely used in the literature to present the effects of the total power losses in PV systems.
