Gravity and wind loads, creep, rainfall, and soil properties cause the most errors. Spot deviation depends on the error magnitude, heliostat position, and season. Mathematical model-based solar tracking corrects most errors. Heliostat fields represent the primary energy input for concentrating solar-thermal power based on power tower technology.

Shading on photovoltaic (PV) modules induces disproportionate impacts on power production. This paper presents a fault detection method able to identify anomalies on PV systems such as shading problems. The presence of localized shading on PV modules leads to an overheating of the shaded PV cells despite the activation of by-pass diodes.

Reliability Analysis of Solar PV System The FTA approach is used in this section to perform a reliability analysis on the solar PV system. The required data on faults/failures and fault failure rates are gathered from the published literature. To identify critical faults, the developed FT is subjected to qualitative and quantitative analysis.
It is observed that the occurrence of different faults in the PV system may reduce the power output by up to 19% of its capacity. Hence the overall effect of the presence of fault would be lowered power generation, reduced reliability and lifetime, and increased operation and maintenance cost of the PV system.
In this paper, the FTA is used for solar PV system reliability assessment. FTA basically comprises cause and effect analysis which provides information about how the failures are propagated into the system and how failure in the components leads to the complete or partial failure of the system.
Qualitative FTA of a Solar PV System The qualitative analysis includes the identification of the relationship between basic events with a corresponding intermediate event and intermediate events with a top event. The qualitative analysis of the solar PV system reveals the connection between basic and intermediate events and a top event.
The Fault Tree (FT) for the DC side of a solar photovoltaic (PV) system is constructed using the data published in the literature. The system reliability model is developed using the median failure rates of 33 components/ faults.
In the case of series configuration, all events are regarded as critical. The reliability of solar PV () systems can be estimated using the probability of non-occurrence of events/faults as follows: E1 = indicates that the event 1 does not occur; E2 = indicates that the event 2 does not occur; ;
