“…In order to avoid dust accumulation the pitch angle should be set to zero early morning or late in the evening to drop slide off the dust [2]. The electrical efficiency is increased and cell degradation is reduced with time by proper cooling.…”

The solar panel is one of the most sought after methods to produce electrical energy for domestic purposes. Solar PV/T systems converts solar irradiation into thermal and electrical energy. Module is made of Poly c-Si material. This experiment aims at analysing the comparative performance of hybrid solar PV/T water collectors connected in series and parallel. It was conducted in Saranathan College of Engineering, Tiruchirapalli-12. It is located at latitude of 10.7560°N and longitude of 78.6513°E. The maximum temperature of water obtained was 42.8°C and 40.8°C respectively in series and parallel. Overall the parallel connected PV/T system's performance is 12.12% higher than the series connected PV/T system.

“…The dust accumulation on PVs surfaces is a natural phenomenon that significantly reduces the PV panels' efficiency by upwards of 70e80% [27,28]. For example, in the cleanest region in the word, United Kingdom, dust reduces the PVs efficiency by 5e6% if they are not cleaned after one month [27].…”

a b s t r a c tThis paper applies a new dynamical electrical array reconfiguration strategy on photovoltaic (PV) panels arrangement based on the connection of all PV panels on two parallel groups to reach the 24 V requested by the considered load and providing a maximum output current by connecting in series the two groups. If one of the PV panels or more are shaded, dusty or faulty the connection of the others in the same group will be automatically modified to maintain the requested load output voltage. This dynamical reconfiguration allows also limiting the lost power, due to the incriminate panel, by switching off this panels and reconfiguration the topology. As a result, a real time adaptation of a switch matrix allows a selfability to maintain a constant load voltage. Moreover, a minimum number of PV panels are switched off by isolating the effect of unhealthy panels. In addition, the proposed solution can also be applied for identifying and locating the shaded, dusty and faulty panel. Experimental setup has been built and the results validate the proposed method.

“…Furthermore, dust is also known to affect photovoltaic performance considering that it may prevent radiations from reaching the photovoltaic module [3]. Previous studies about the effects of dust on PV and solar thermal panels date back to over seventy years ago and focus on the thermal cells and the effect of dust on the reflectance of mirrors [4]. For instance, Sayigh who is credited as a pioneer in the Gulf region conducted a detailed investigation on the effect of dust on solar flat-plate collectors.…”

Investigating the Effect of Titanium Dioxide (TiO2) Pollution on the Performance of the Mono-crystalline Solar Module

et al. 2017

This paper presents a study of titanium oxide TiO2 as one of the components of dust pollution affecting the PV performance. This pollutant can be found in various quantities in different locations around the world. The production of energy by different types of photovoltaic systems is very sensitive and depends on various environmental factors. Dust is one of the main contributing factors, yet the type of the dust is often neglected when studying the behaviour of the solar panel. In this experimental work we have studied the performance of the monocrystalline solar module as affected by the density of TiO2. The reduction of the PV module power caused by titanium dioxide under various mass densities was investigated. The results showed that the TiO2 has a significant effect on the PV output power. The dust density varied between 0-125 g.m -2 . The corresponding reduction of the PV output power increased from 0 to 86.7%. This is based on various influencing parameters such as: short circuit current (Isc), maximum current (Im), open circuit voltage (Voc), maximum voltage (Vm), maximum power (Pm) and efficiency (E). Two functions are proposed as a mathematical model in order to explain this behaviour, namely the exponential and Fourier functions. The coefficients of all general models are valid for this type of dust with a density value ranging from 0-125 g.m -2 .
