[PDF Version]A defect is an unexpected or unusual happening which was not observed on the PV plant before. However, defects often are not the cause of power loss in the PV plants: they affect PV modules, for example, in terms of appearance (Quater et al.,2014).
In this study, we analysed thermal defects in 3.3 million PV modules located in the UK. Our findings show that 36.5% of all PV modules had thermal defects, with 900,000 displaying single or multiple hotspots and ~250,000 exhibiting heated substrings. We also observed an average temperature increase of 21.7 °C in defective PV modules.
We also observed an average temperature increase of 21.7 °C in defective PV modules. Additionally, two PV assets with 19.25 and 8.59% thermal defects were examined for PV degradation, and results revealed a higher degradation rate when more defects are present.
Generally,any effect on the PV module or device which decreases the performance of the plant, or even influences the module characteristics, is considered a failure. A defect is an unexpected or unusual happening which was not observed on the PV plant before.
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.

Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
The photovoltaic sector is now led by silicon solar cells because of their well-established technology and relatively high efficiency. Currently, industrially made silicon solar modules have an efficiency between 16% and 22% (Anon (2023b)).
In 1985, researchers at University of New South Wales, Australia were able to construct a solar cell that has over 20% efficiency. A 20% efficiency solar cell were patented in 1992. In the 21st century, the efficiency continues to rise and and the future forecast shows that there are no signs that the efficiency would stop increasing.
Solar cell efficiencies vary from 6% for amorphous silicon-based solar cells to 44.0% with multiple-junction production cells and 44.4% with multiple dies assembled into a hybrid package. Solar cell energy conversion efficiencies for commercially available multicrystalline Si solar cells are around 14–19%.

Accordingly, this review addresses comprehensively, all the key environmental impacts associated with solar PV power generation.
Although PV technology significantly reduces emissions of pollutants and greenhouse gases, it also has negative environmental impacts. These include biodiversity and habitat loss, climatic impacts, resource consumption, and PV module disposal.
The European Green Plan states that it is critical to decarbonize the European Union's energy system to meet the climate targets set for 2030 and 2050. According to the REPowerEU plan, photovoltaic systems will play a crucial role in this process. Therefore, it is important to understand the impact of PV installations on the environment.
The results revealed that the negative environmental impacts of PV systems could be substantially mitigated using optimized design, development of novel materials, minimize the use of hazardous materials, recycling whenever possible, and careful site selection.
The location of the PV system in relation to local sources of air pollution must be considered. Local industrial pollution of the atmosphere and vehicular traffic can reduce the received radiation and also could have a significant soiling effect on the PV modules .
