This study attempts to enhance the overall efficiency of a photo voltaic solar panel by employing a dual-coating approach. The initial coating consists of a Silica-based anti-reflective material synthesized through an acid-catalyzed sol-gel process, utilizing cetyltrimethylammonium bromide as a template. Subsequently, the second coating was formulated using a phase change material, such as expanded graphite infused with paraffin jelly. The coating materials were characterized using Ultraviolet-Visual ray spectroscopy, Fourier Transform-Infrared Ray spectroscopy, Field Emission-Scanning Electron Microscopy, X-Ray Diffraction spectroscopy, and Thermogravimetry analysis. The panels' performance had been investigated under three conditions: uncoated, single-coated, and double-coated. These panels were subjected to both indoor and outdoor experiments. Indoor tests were conducted in a laboratory with induced irradiance levels of 350, 600, and 850 W/m2. The corresponding variations in maximum power output, maximum surface temperature and peak current were recorded. For the outdoor experiments, two sets of panels were installed on a rooftop. One set underwent daily surface cleaning, while the other was left untouched, allowing dust accumulation. Over a 45-day period, outdoor experiments were carried out (daily cleaned and unclean panels) to examine the impact of dust accumulation on power loss, current, voltage, surface temperature, energy generation and panel efficiency. Upon comparing the performance of uncoated, single-coated, and double-coated solar panels, it was observed that photovoltaic solar panels coated with both silica-based anti-reflective coating and paraffin jelly-infused expanded graphite coating exhibited superior performance when compared to other coating options.

Deployment of solar photovoltaic panels are significantly rising to tackle adverse effects of climate change however, factors affecting output need to be categorized in addition to latitude angle and space. It is important to consider the atmospheric impact which can drastically change output power of solar panels. This study covers dust accumulation of soil, sand and ash at variable weights to foresee its effects on panel power output. Mixtures of these particles at multiple constituents were also analyzed. Experimental results indicated that clean panel gives maximum power output of 21.37W and exergy efficiency of 7.96% whereas ash accumulation showed worst results of 2.88W power output and 1.07% exergy efficiency at 700W/m2 and 50g dust accumulation. Other parameters like energy destruction, exergy losses and sustainability index were also analyzed. Trends have been illustrated in graphs along with the change in solar intensity and dust accumulations.

“…There has been a significant increase in dust studies since 2011, where almost half of it was conducted in Saudi Arabia, India, and Malaysia. The dust decomposition density within 30-45 days was recorded by the few researchers, such as (in ) 3.8 (Malaysia) [ 4 ], 4.6 (Pakistan) [ 10 ], 5 (July) to 28 (August and October) in Saudi Arabia [ 11 ], 5.12 ± 0.55 (Western India) [ 12 ], 31-127 (Qatar), 0.2-2.44 (Kuwait), and 4.48-15.84 (Egypt) [ 13 ]. In arid regions like Iran, less than 1km visibility was reported during the dust storm (March to May) [ 14 ].…”

Automated water recycle (AWR) method for dust removal from rooftop photovoltaic (PV) at Johor, Malaysia

et al. 2022

Wet dust on the Photovoltaic (PV) surface is a persistent problem that is merely considered for rooftop based PV cleaning under a high humid climate like Malaysia. This paper proposes an Automated Water Recycle (AWR) method encompassing a water recycling unit for rooftop PV cleaning with the aim to enhance the electrical performance. This study makes a major contribution by developing a new model to correlate output power ($$P_{out}$$ P out ) and dust-fall factor. For model validation, we conducted an experiment of taking one set of Monocrystalline PV (mono) on a $$340\frac{W}{m^{2}}$$ 340 W m 2 of medium luminance day. One mono module was cleaned by AWR - pressurized water sprayed through 11 small holes over its front surface, while the other module was left with no-cleaning. The dust-contaminated water was filtered and collected back to the tank for recycling process. The water loss per cleaning cycle was achieved 0.32%, which was normalized to net loss of 28.8% at a frequency of 1 cycle/day for 90 days of operation. We observed that $$P_{out}$$ P out of no-cleaning PV was decreased by 29.44% than that of AWR method. From this experimental data also, a unique and more accurate model is created for $$P_{out}$$ P out prediction, which is much simpler compared to multivariables equation. Our investigation offers important insights into the accuracy of this regression model demonstrated by $$R^{2}=0.744$$ R 2 = 0.744 or a strong negative quadratic relationship between $$P_{out}$$ P out and dust-fall. The cleaning of PV modules is expected to save significant energy to reduce the payback period. Article Highlights An automated water recycle method for cleaning dust-fall in rooftop photovoltaic module is proposed. Both simulation and experimental models are developed to predict output power of the photovoltaic module. Proposed method can produce 24.40% more output power than a no-cleaning system with a mere water loss of 0.32%/cycle.
