Solar PV panels or solar photovoltaic panels are what you see installed on the roofs of parking area homes etc, and these serve the function of generating energy by converting the light falling on to them. It has been observed that the solar PV conductor layer yields comparatively lower output, and the culprit is none other than dust and other debris.
Thus, the biggest challenge in adopting solar energy comes in the form of maintenance requirements of the solar PV panels. These panels need to be put through rigorous and regular cleaning schedule which is neither practically possible nor financially feasible. Thus, smearing the panels with a solar PV coating is found to be a workable solution.
A coating of solar PV is nothing but a thin coat made of hydrophobic material that forms a protective shield on the panel. This coating performs number of functions:
- Maximize PV output: Every solar panel is built with an intention to extract a pre-determined output. The solar PV coating ensures that this output level is not pulled down by the external agents like dirt, dust and debris. Researchers have recognized around 17 contaminants that can interfere with the functioning of the PV panels. The coating is made to fight against the majority of these.
- Improves UV and chemical resistance: The dust and dirt and the prevalence of industrial chemicals prove to be a big deterrent to the performance of solar PV panels. With the improvement in light transmission, curing capabilities and other virtues of selective deposition, the PV coating can make the panel chemicals-safe.
- Easy cleaning: Panels can be cleaned with limited supply of water as the coating forms a hydrophobic layer which rolls off the dust and dirt from the surface. Thus, no mechanical wiping of panels is required.
Solar PV coatings, therefore, have become an essential part of power generation set. Because of their low cost, they have gained easy popularity amongst the users.
