The performance of PV panel depends on the incoming sunlight on its surface. The accumulated airborne dust particles on panel surface creates a barrier in the path of sunlight and panel surface, which significantly reduces the amount of solar radiation falling on the panel surface. The present study shows a significant reduction in short circuit current and power output of PV panel due to dust deposition on its surface, whereas the reduction in open circuit voltage is not much prominent. This study has been carried in the field as well as in the laboratory. The reduction in maximum power output of PV panel for both the studies ensures a linear relation with the dust deposition on its surface. In the field study, the reduction in the power output due to 12.86gm of dust deposition on the panel surface was 43.18%, whereas in the laboratory study it was 44.75% due to 11gm of dust depositionArticle History: Received July 10th 2017; Received in revised form Sept 15th 2017x; Accepted 1st Oct 2017; Available onlineHow to Cite This Article: Tripathi, A.K., Aruna, M. and Murthy, Ch.,S.N.

The surface temperature of PV panel has an adverse impact on its performance. The several electrical parameters of PV panel, such as open circuit voltage, short circuit current, power output and fill factor depends on the surface temperature of PV panel. In the present study, an experimental work was carried out to investigate the influence of PV panel surface temperature on its electrical parameters. The results obtained from this experimental study show a significant reduction in the performance of PV panel with an increase in panel surface temperature. A 5W PV panel experienced a 0.4% decrease in open circuit voltage for every 1°C increase in panel surface temperature. Similarly, there was 0.6% and 0.32% decrease in maximum power output and in fill factor, respectively, for every 1°C increase in panel surface temperature. On the other hand, the short circuit current increases with the increase in surface temperature at the rate of 0.09%/°C.

Worldwide photovoltaic power generation is affected by deposited dust on photovoltaic (PV) systems, which creates soiling losses. In this work, factors that have a detrimental influence on dust deposition and an impact on PV systems performance were reviewed. The different ways that dust deposition can be a barrier for India’s energy security plan involving PV were also discussed. Different available cleaning techniques were also introduced. The nature, size, and morphology of dust particles vary with geographical location. Any increase of the PV tilt angle, or high wind speed and heavy rain showers reduce dust deposition. Deposited dust reduces the incident transmitted light on the PV, which has an adverse impact on the reduction of short circuit current. However, the open-circuit voltage has a reduced effect due to dust deposition. The enhancement of temperature caused by dust-covered PVs is still a debatable area. A universal cleaning technique is required to eliminate the soiling losses from PV. India has a solar mission to generate 100 GW of PV power by 2022. However, India’s poor air quality can undermine efforts to achieve this target.

The photovoltaic (PV) panel performances are dependent upon many factors. A study was executed to ascertain the effect of a V-Trough Concentrator (VTC) to be engaged on a PV Panel in this research where the performance of PV panels are compared at different surface temperatures both back and front. The experiment was conducted using two similar rated monocrystalline PV panels. One of the PV panels was installed with a VTC while the other is without the VTC that served as Control for benchmark purposes. The optimum VTC selected is a 60° VTC. Both PV systems were built with a lower supporting mechanism and were placed to operate under similar operating and weather situations, while the PV panel surface temperature both front surface and back surface, Open Circuit Voltage (Voc), as well as Short-Circuit Current (Isc) readings are being recorded down at specific time. The theoretical output is determined and compared. This paper ends with a presentation of the results obtained in a study on the PV panel surfaces temperature in relation to its performance by PV system using a 60o VTC.

Self Cleaning

The integration of transparent electro-dynamic screen (EDS) on the front surface of solar mirrors and glass cover plates of photovoltaic panels has a strong potential to significantly reduce the frequency of water-based cleaning needed to mitigate losses from dust depositions present in arid regions. The objective of our research was to develop and evaluate prototype transparent EDS-integrated mirrors and solar panels for their self-cleaning functions, with an aim to keep the collectors clean at a low cost without water or manual labor. This paper focuses on the design, fabrication, and laboratory evaluation of a prototype EDS integrated second surface mirrors and solar panels. The EDS consists of a set of parallel transparent electrodes screen-printed on the optical surface and embedded in a thin transparent dielectric film. By applying three-phase, low current, low frequency high voltage-pulses to the electrodes, electro-dynamic repulsion forces and a traveling wave are created for removing dust particles from the surface of the collectors. Design and construction of an environmental test chamber to simulate different atmospheric conditions of semi-arid and arid areas with respect to temperature, RH, and dust deposition conditions are briefly described. A non-contact specular reflectometer was designed, constructed and calibrated for measuring specular reflection efficiency of the mirrors. Laboratory evaluation of the performance of the EDS-integrated collectors was completed using humidity controlled environment test chamber where the prototype mirrors and panels were examined for their self-cleaning action. In each experiment, the solar collectors were loaded with dust until the specular reflectance of the test mirror or the short circuit current of the panel showed a significant decrease. The EDS was then operated for one minute and the relative output was recorded. The results show that the specular reflectivity of EDS mirrors and the short circuit current of the EDS panels can be restored by more than 90% of the values measured under the clean conditions.

Yearly Average

The electrical characteristics of photovoltaic (PV) modules are affected by solar radiation and module temperature in outdoor environment. It was found that polycrystalline gained a yearly 0.50°C more average module temperature than monocrystalline. Non-crystalline amorphous modules got a yearly 0.83°C more average temperature than thin film modules. The attainment and release of module temperature was related with material properties of PV module technologies. The amorphous module gave 5.7%, 2.7% and 15.0% more yearly average open-circuit voltage than polycrystalline, monocrystalline and thin film modules. Besides that, the thin film modules gave 6.5% and 1.7%, 9.3% and 4.0%, and 11.3% and 8.8% more yearly average normalized short-circuit current and power output than polycrystalline, monocrystalline and thin film modules respectively. It was shown that the maximum annual average open-circuit voltage was given by amorphous modules and maximum short-circuit current and power output by thin film modules during the study period.

One of the major concerns for continuous solar photovoltaic (PV) generation is partial shading. The movement of clouds, shadow of buildings, trees, birds, litter and dust, etc., can lead to partial shadow conditions (PSCs). The PSCs have caused inconsistent power losses in the PV modules. This leads to a shortage of electricity production and the presence in the PV curve of several peaks. One of the simplest solutions to PSC’s is the PV configurations. The objective of this paper is modelling and simulation of solar PV system in various shading scenarios for KC200GT 200 W, 5 x 5 configurations that includes Series/Parallel (SP), Total-Cross-Tied (TCT), Triple-Tied (TT), Bridge-Link (BL) configurations. Real time PSC’s such as corner, center, frame, random, diagonal, right side end shading conditions are evaluated under all PV array configurations. A comparative analysis is carried out for the parameters such as open circuit voltage, short circuit current, maximum power point, panel mismatch losses, fill factor, efficiency under all PV configurations considering PSC’s. From the comparison analysis best configuration will be presented.

A Solar panel is rated such that it can yield optimum output under Standard Testing Conditions (STC). But due to different environmental factors the efficiency of the panel is reduced gradually after installation. Accumulation of dust on solar PV panel is one such natural phenomenon. When dust accumulates on the PV panel, the temperature of the cells increases which subsequently decreases the open circuit voltage. The short circuit current is also reduced as deposition of dust causes shading on the panel surface. As a result, the output power of the module decreases. In this paper, the effect of dust on the performance of the photovoltaic module has been studied. The increase in temperature due to dust accumulation has been visualized through the thermal camera and the reduction in power has been analyzed through PSpice simulation and experimental data for the different amount of dust accumulated.

This paper reports on the feasibility of a tree-shaped hybrid nanogenerator (TSHG) made of flexible sheets of photovoltaic (PV) and piezoelectric (piezo) films for harnessing both wind and solar energy. The proposed system has been designed to produce electricity if there is any light, wind or strong rainfall. It shows how the power developed by each piezo film sheet was integrated in conjunction with its limited power output which is produced by the sporadic movement of the sheets. Regardless of its magnitude, the AC power output of each piezo film sheet was converted with a full wave bridge rectifier and then passed to a capacitor. The TSHG has an excellent performance with an open circuit voltage of 5.071 V, a short-circuit current of 1.282 mA, and a maximum power output of 3.42 mW at a loading resistance of 5 kΩ. Moreover, a wind driven TSHG was capable of charging a 1000 µF capacitor, which was subsequently discharged through LED lighting.

This study investigated the effect of dust to the performance degradation of PV street lights deployed at several areas (coastal, urban, industry, and village) in Kupang city. Results showed that maximum power output (Pmax) of all modules decreased by 9 % to 14 %. Short circuit current (Isc) was the parameter strongly affected by dust compared to open circuit voltage (Voc). Performance of the PV modules increased back to their initial conditions after cleaning. This was indicated by the increasing of Isc and Voc of the modules that leading to the escalating of their Pmax values. The worst effect of dust was exhibited by PV modules installed at coastal area. A simple analysis revealed that the module would lose 87.75 Wh of energy d–1. This study suggested that dust derating factor applied for PV street light design in Kupang should be higher than the standard (5 %).
