Researchers from the Indian Institute of Engineering Science and Technology, Shibpur’s (IIEST Shibpur) have developed a novel physics-based model to estimate dust accumulation on the front and rear surfaces of bifacial modules.
“This model is equally applicable for both rooftop plant and commercial ones,” researcher Saheli Sengupta told pv magazine. “In India, a larger plant with bifacial modules is not yet available and hence we could not validate the model for the larger set-up. But this is in our research program to carry out the same for larger plants from India and abroad.”
The proposed model considers a few input parameters such as particulate matter (PM) concentration, panel tilt, the sun’s angle of incident, solar radiation, albedo, and PV module specifications. It also considers weather parameters such as wind direction, speed, and ambient temperature.
“The considerations made in this analysis are that the shape of the particles is assumed to be spherical; the dust deposition over the module is considered to be uniform; and the effect of different composition of dust is not considered separately,” said the academics.
