The measurements included solar radiation, PV panel's surface temperature, PV panel's output (DC current, DC voltage), pump's discharge, pressure, dust accumulation density g/m 2, and I-V.
The wide range reduction in electrical energy is due to soiling strongly affecting the slope, orientation, and characteristics of the solar PV module such as type of coating, surface roughness, etc. Energy reduction due to soiling for PV fixed horizontally 8%–22% is much greater than PV tilted by 45° (1–8%) (García et al., 2011 .
The foremost requirement is the structural strength of the roof, which should be capable of supporting the additional weight of the solar panels and the mounting structure. The solar panel mounting structure is usually made of mild steel or aluminum, which adds minimal weight but provides adequate support to the panels 1.
The surface roughness and antireflective coatings of superstrates heavily influence the incident angle effect. The purpose of this study is to test and validate the draft International Electrotechnical

6 FAQs about [Photovoltaic panel surface roughness standard requirements]
What are solar photovoltaic design guidelines?
In addition to the IRC and IBC, the Structural Engineers Association of California (SEAOC) has published solar photovoltaic (PV) design guidelines, which provide specific recommendations for solar array installations on low-slope roofs 3.
What are the structural requirements for solar panels?
Structural requirements for solar panels are crucial to ensure their durability, safety, and efficient performance. These requirements vary depending on the type of installation, such as rooftop or ground-mounted systems, as well as the specific location and environmental factors.
How much dust does a PV module need?
Higher dust density reduces PV short-circuit current, open-circuit voltage, and output power. Dust with a density of 10g/m 2 can reduce the maximum PV output by about 34% 9. Regular cleaning of PV modules is essential to maintain their performance.
Should solar panel surfaces be cleaned?
The cleaning of solar panel surfaces becomes problematic without labor-free and water-saving approaches. Engineers have been exploring surface self-cleaning methods other than traditional cleaning to mitigate surface soiling and improve PV module efficiency.
How efficient are PV panels compared to reference panels?
The average electrical efficiency of the PV panels with coating and mechanical vibrator declined by 12.94% over 6 weeks of operation, whereas the efficiency of the PV panel without coating reduced by 24.46%. The reference panel, on the other hand, had a 33% decrease in efficiency.
What factors affect the performance of a solar PV module?
The solar PV module's performance depends on the PM 10 concentration, dust loading (mgm −2), and fine dust particle concentration around the globe. Location, installation, dust type, and environment are all causes of dust accumulation on PV surfaces.
