“…The result was in a good correlation to the shinning area of the Sun's disc that was about 12% (the coverage area of the Sun's disc by the Moon in Bandung was about 88.76%; see Figure 6e). The decrease in solar intensity during the eclipse has been mentioned in the current literatures (Libra, 2016;) When the partial phase II started, the rate increased rapidly (rate = 1,430 lux/min), confirming the appearance of the Sun to reach normal. In addition, the intensities after 08:20 in all samples fluctuated between 30,000 and 60,000 mV due to the hysteresis and the limitation of our lux sensors.…”

“…(Abram et al, 2000) Solar eclipse phenomenon has attracted researchers from various fields. Many researchers investigated the incidents related to the meteorological parameters (e.g., temperature, Nishanth et al, 2011) wind speed, (Nishanth et al, 2011) gravity, (Altadill et al, 2001;Šauli et al, 2006) humidity, (Nishanth et al, 2011) geomagnetic field, (Özcan et al, 2004) ionospheric electron content, (Liu et al, 1999) and light irradiation Zerefos et al, 2001;Nishanth et al, 2011;Libra et al, 2016)) and the photochemical properties in the atmosphere (Hunt 1965;Bojkov 1968;Eastman et al, 1980;Abram et al, 2000;Chudzyński et al, 2001;Tzanis et al, 2008;Sharma et al, 2010;Nishanth et al, 2011). However, no research investigates on the impact of solar eclipse to the photodecomposition of organic material in the Earth.…”

The present study investigated the photodecomposition of an organic material during the partial (88.76%) solar eclipse phenomenon of 9 March 2016 in Bandung, Indonesia. Curcumin and anatase titanium dioxide (TiO 2 ) particles were used as models of organic material and photocatalyst, respectively. The influence of the process parameters (i.e., curcumin concentration and the amount of TiO 2 ) on the photodecomposition process was also investigated. The results showed that the curcumin was decomposed along with the solar light irradiation time. During the solar eclipse, the photodecomposition rate is suddenly down. The partial solar eclipse provided a slower photodecomposition process than the process under sunny days (conducted on 8 and 10 March 2016). The concentration of curcumin and the amount of TiO 2 also have played an important role in the photodecomposition, in which the lower concentration of curcumin and the higher amount of TiO 2 have a correlation to the obtainment of higher photodecomposition rate.

“…Prague, Czech Republic, had a partial solar eclipse on this day. A study conducted by Libra et al [8] explained the behavior of a laboratory 510 peak watt PV system during the eclipse and explained in terms of a theoretical model taking into account the temperature and wind speed. It correlated the module power to the measured incident irradiance.…”

Abstract. The power output of a 4.85 kW residential photovoltaic (PV) system located in Rochester, NY is monitored during the partial solar eclipse of August 21, 2017. The data is compared with the data on a day before and on the same day, a year ago. The area of exposed solar disk is measured using astrophotography every 16 s of the eclipse. Global solar irradiance is estimated using the eclipse shading, time of the day, location coordinates, atmospheric conditions and panel orientation. A sharp decline, as expected in the energy produced is observed at the time of the peak of the eclipse. The observed data of the PV energy produced is related with the model calculations taking into account solar eclipse coverage and cloudiness conditions. The paper provides a cohesive approach of irradiance calculations and obtaining anticipated PV performance.

“…However, it does not quantify the performance of the system using one of the standard accepted metrics such as performance ratio (PR), energy performance index, or PPI as recognised by the industry [13][14][15][16]. A similar study of PV performance was conducted by other authors too, but they primarily relied on comparing the net PV generation on the day of the eclipse versus the following: generation of the same system on the same date of the previous year or generation of the same system on the date prior to or next to the date of the eclipse [17,18]. While these methods provide a visual idea about the impact of the eclipse, they do not quantify the impacts as a measurable metric.…”

Photovoltaic (PV) systems depend on irradiance, ambient temperature and module temperature. A solar eclipse causes significant changes in these parameters, thereby impacting PV generation profile, performance, and power quality of larger grid where they connect to. This paper presents a case study to evaluate the impacts of the solar eclipse of August 21, 2017 on two real-world grid-tied PV systems (1.4MW and 355kW) in Miami and Daytona, Florida, the feeders they are connected to, and the management areas they belong to. Four types of analyses are conducted to obtain a comprehensive picture of the impacts using 1-minute PV generation data, hourly weather data, real feeder parameters, and daily reliability data. These analyses include: individual PV system performance measurement using power performance index; power quality analysis at the point of interconnection; a study on the operation of voltage regulating devices on the feeders during eclipse peak using an IEEE 8500 test case distribution feeder; and reliability study involving a multilayer perceptron framework for forecasting system reliability of the management areas. Results from this study provide a unique insight into how solar eclipses impact the behavior of PV systems and the grid, which would be of concern to electric utilities in future high penetration scenarios.
