The researchers at the University of Hedersford have found the largest study of the solar panel effectiveness date and discovered that parts of the country are "25 percent" due to the region's "hot spots". Hotspots also appeared to be more northern in England than in the south.
Dr. Mahmoud Ermish, lecturer in electronic and controlling engineers and co-organizer of the photoelectric laboratory, analyzed 2,580 polycrystalline silicon photolithic panels UK. Great Britain has been in the past for two years and the demand is constantly growing with renewable energy.
Following the quantitative evaluation of data, Dr. Dimas discovered that the panels in the hot spots have discovered energy generation, which is less than what has not happened. He also found that the location was the main contribution to the hot spot.
In the hotspots of the photooloptes there are elevated temperature zones affecting only part of the solar panel. They are the localized reduction of efficiency and are the main cause of accelerated PV outdated, which often causes permanent damage to the solar panel life.
Domi Dimi's opinion is the first time that the hot spots influence the effectiveness of PV panels from such large-scale databases and declare that the project has been identified as the preferred location for British hot spots.
"This study has shown unprecedented density hot spots in northern England," said Dai Dhimish. "90% of the hot spots are located in hot spots and most of them are indoor, less noticeable on the coast."
Inequality of solar panel execution
Dr. Dimas says that this confirms the results of the previous survey, which concludes when the affected cells are partially shaded, it increases the likelihood of a hot spot.
But he said that it was surprising that there was no less clear area around the coastal regions, which believes that the cold winds in the ocean will protect the total temperature of the PV panels and hinder the hotspots.
In order to enhance the reliability and durability of future residential photovoltaics installations, Dr. Dhimish has made three recommendations.
"PV panels, or inverse detachable diodes that affect PV cells in many hotspots, will significantly reduce reliability and generate energy pv installation," he said.
"Secondly, it is recommended to set up coastal zones of coastal areas because it is less likely to affect the hot spot phenomenon and ultimately the solar power industry should launch an investigation on the PV hotspot on the accuracy of the maximum capacity accuracy (MPPT) on the market."
The research paper, including all the collected data, must be published in the reviewed journal IEEE transaction on electronic devices, Co-authored Dr Dhimish, Dr. Violeta Holmes and Dr. Peter Mary, entitled Evaluation of performance loss and performance of hot spotted photo-motor modules.
