Raptor Maps points to growing problem of PV system underperformance – pv magazine International


Raptor Maps analyzed 24.5 GW of huge photo voltaic property and decided that energy losses resulting from tools anomalies will virtually double from 1.61% in 2019 to three.13% in 2022. On the module degree, anomalies of the cell and diode are the commonest points, it stated.

US-based Raptor Maps has revealed its newest annual report on world PV system underperformance. The photo voltaic lifecycle administration software program specialist conducts aerial inspections of a complete of 24.5 GW of main photo voltaic methods.

Inspection statistics present that photo voltaic property have gotten extra anomalous yearly. Underperformance resulting from anomalies virtually doubled from 1.61% in 2019 to three.13% in 2022, the corporate stated. Energy loss has elevated by 94% since 2019, it added, indicating that energy loss pushed by the anomaly might develop to virtually 6% in 2025 on the present price.

Raptor Maps estimates annual losses of $82 million for the 24.5 GW property it analyzed in 2022, at a mean of $3,350 annual losses per megawatt.

“Extrapolating all the world PV capability (by the tip of 2021, excluding residential) interprets right into a $2.5 billion annual lack of income for the trade,” the corporate stated.

The report consists of information on low efficiency on the web site dimension and anomalies on the module degree for the primary time. The figures present that smaller websites have the best common energy losses as a proportion of their technology capability. Nevertheless, the biggest websites present a better common energy loss. Areas between 100 MW and 200 MW in dimension have a mean energy lack of 4.04% – 29% greater than the worldwide common.

“Websites bigger than 200 MW misplaced, on common, about $4,320 per MW, with some websites dropping as much as $12,900 per MW,” says Raptor Maps.

The report reveals that system-level anomalies are the largest drivers of energy outages, with string, inverter, and combiner anomalies affecting probably the most energy as a proportion of complete energy analyzed. , at 1.06%, 0.70%, and 0.67%, respectively. String anomalies had been reported to be accountable for 34% of misplaced income, whereas inverter and combiner anomalies had been accountable for 22% and 21%, respectively.

On the module degree, Jinko Photo voltaic, First Photo voltaic, Trina Photo voltaic, Canadian Photo voltaic, and Longi are the highest 5 producers of the analyzed property. Cell and diode anomalies are the commonest anomalies on the module and sub-module degree amongst these producers, in response to Raptor Maps. Mixed, the 2 classes account for practically 70% of detected defects. Bodily injury accounts for 18% of defects.

Monocrystalline modules had been discovered to be much less faulty than polycrystalline and skinny movie applied sciences, at 65% and 41%, respectively. The inspected thin-film modules are stated to be extra inclined to bodily injury similar to cracking, delamination, and warping. They present 3 times extra bodily injury than polycrystalline and 12 instances greater than monocrystalline. Scorching spots had been additionally discovered extra steadily in thin-film modules than within the different two applied sciences.

“The report highlights the necessity for asset homeowners and managers to observe tools efficiency over time, proactively determine upkeep points and guarantee declare alternatives,” stated the Raptor Maps.
