“…However, challenges in using solar panels include inconsistent performance and susceptibility to environmental factors [2]. The current market offers PV panels with 8%-12% conversion efficiency, leaving much sunlight untapped [3]. Regular maintenance is essential as panels are being exposed to harsh weather [4], shading, snow, dust [5], rain and smoke [6].…”

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.

“…It has the benefit of being able to provide highly accurate estimates of the PV system that can be installed at the proposed location, monthly and annual power production, performance ratio, layout of PV system, number of inverters and PV modules, single line diagram (SLD), losses in photovoltaic system, shading analysis, electric cabling selection, global horizontal irradiance (GHI), diffuse horizontal irradiance (DHI), plane of the array (POA) irradiation, temperature indicators, computer-aided drafting (CAD) tools and SketchUp shading integration. It is also feasible to select required components of system such as rating and type (Si-Mono, Si-Poly) of photovoltaic modules, inverters rating, tilt angle, azimuth angle, orientation (horizontal and vertical mounting) of photovoltaic modules, frame size, array row arrangement, inter-row spacing between PV array, and AC/DC electric cables during the design process for PV systems (Habib et al, 2023b;Habib et al, 2023c). When developing a simulations model of PV plants, PVSyst incorporates meteorological data from the NASA-SSE (Solar System Exploration, 2023), Metronome (Meteonorm Software, 2023), and Solar Prospector (Solar Prospector, 2021) databases.…”

Decentralized energy generation systems based on renewable sources have significant potential to assist in the sustainable development of developing countries. The small-scale integration of hybrid renewable energy systems in off-grid communities has not been thoroughly researched. The primary objective is to develop a preliminary design for a PV/biogas hybrid system that can meet the energy needs of an off-grid community center. A survey was conducted to calculate the energy demands of an off-grid community center and a hybrid renewable system has been designed to supply the electricity. The optimum designed system is evaluated by the PVSYST simulation software and SuperPro Designer software. The annual production of the PV system is 34428 kWh/year, specific production is 1118 kWh/kWp/year, and the performance ratio is 81.72%. All the factors that contribute to energy loss are considered in designing a PV system. The average operating efficiency of the inverter is 92.6%, and global inverter losses are 2752.4 kWh. The biogas simulation findings show an adequate match with the composition of conventional biogas and contains 89.64% methane and 5.99% carbon dioxide content. Two sensitivity analyses of biogas based on hydraulic retention time and moisture content have been performed. Measurements readings of hourly data are used to analyse the performance of PV, biogas system as well as the hybrid system performance. At day time, the maximum power generation of the hybrid PV/Biogas and the maximum load demand of the community at that time are 25.2 kW and 24.31 kW, respectively. At night time, the maximum power generation of the hybrid system and the maximum load demand are 9 kW and 8.3 kW, respectively. The power factor (PF) of the system fluctuates between 0.92 and 0.98 and the frequency of the system is constant at 50 HZ.
