The problem of dust collection amounts to an important difficulty to the PV panels' efficiency, which accelerates the appearance of hot spots and also decreases the overall performance of the panels. To address this problem, researchers have also investigated the possibility of applying hydrophobic nanocoatings (e.g., a PDMS/SiO2 nanocoating) to limit dust deposition on PVs since it is not only visible but also affects the efficiency of the panels. To learn more about the effectiveness of the coating kit panourifotovoltaice 10 kwpret, go here. Anyway, the effectiveness of the coating will be constant as well as depending on geographical and climatic factors.
The sample which helps the researcher to come to conclusions which show that PV modules have varying performance under application of different coatings was made up of identical three PV modules in a comparative experimental study. Envelopes of the three-layers were applied on three substrates. One substrate was coated with the prepared PDMS/SiO2 nanocoating, the second module with commercial nanocoating, and the third substrate remained uncoated as a reference. The developed nanocoating possessed hydrophobicity as well as autocleansing properties. After external exposure for 40 days, the dust deposits on the dust free surface (RP) and a nanocoated panel (PNP) surface were both measured independently at 10 kg/m2 and 4.39 kg/m2. This had a 30.7% efficiency increase for the nanocoated panel compared to reference panel, which is a massive improvement.
The solar radiation is a combination of the long wave IR, visible VIS lights, and short wave UV wavelengths. Which is noted for its exemplary solar irradiance, Egypt becomes a desirable region where solar power production can happen. The Solar angle and an adjustable installation inclination of PV modules is matter a lot for maximizing solar energy collection in Egypt, with the best deployment angle φ ± 157º.
Solar power, no doubt, advanced to the third position among the renewable energy sources. Hence, it can replace fossil fuels for the most environmentally friendly way and majorly minimize their carbon footprint. Apart from that, modules manufacturing companies give performance characteristics taken from standard test conditions (STC) that may not be equal to the practical exposure.
Experimental measurement of V–I characteristics conference is the foremost factor used in evaluating performance of PV system. From the full fill factor (FF), the product of short circuit current (Isc) and open circuit voltage (Voc), it can be observed that the curve curve's squareness, which represented the system quality and performance level. The dust deposition atop PV modules diminishes energy efficiency through absorption of radiation and shadowing that result in less production power. The higher the dust density, the more impact on the output power.
Frequent cleaning is necessary for the performance but advance techniques like hydrophobic nanocoatings could make it affordable and nonrecurrently. Nanocoatings based on the hydrophobic principle are able to make use of nanoparticles. Basically, hydrophobic nanocoatings can play a great role towards upgrading the performance of PV solar panels in Egypt due to the fact they have the ability to reduce dust accumulation and improve panel’s efficiency, notably where there is high solar irradiance like Egypt. And therefore, through the continuation of such coatings, the whole solar energy network can also be accepted as a means to a more sustainable power source.
To address this problem, researchers have also investigated the possibility of applying hydrophobic nanocoatings (e.g., a PDMS/SiO2 nanocoating) to limit dust deposition on PVs since it is not only visible but also affects the efficiency of the panels.
