EXPERIMENTAL INVESTIGATION ON BIFACIAL SOLAR PV MODULE USING DIFFERENT REFLECTIVE MATERIALS UNDER ALBEDO VARIATION

Abstract

Bifacial panels are ideally suited for commercial or utility-scale solar installations, but they can also be employed in some household applications. Bi-facial panels can be used in free-standing structures like the pergola to provide some shade while also generating energy. Bifacial panels can also be used in any other situation where the solar panels are not directly facing the sun. Awnings and canopies made of bifacial solar panels, for example, allow reflected light to reach the panels' backside. Bifacial photovoltaic (PV) is a potentially developed technology that uses absorptivity from the albedo to enhance the amount of power produced per square meter of the PV module. Because both sides of the cell, front and back, can absorb solar radiation, bifacial solar cells may provide a higher energy output than monofacial solar cells. Improved cell efficiency, module reliability, and deployment design of bifacial arrays in a PV plant should continue to be emphasized in bifacial PV efforts to cooptimize front-to-backside energy output for fixed and tracking systems throughout the day. The efficient thermal flow for front, rear, and combination irradiance was determined using these spectra. Single-cell laminates exposed to indoor irradiance had their power output, bifacial gain, and module operating temperature measured. Aluminium foil is a common component of laminates and is widely used in food packaging. It has a higher barrier function against the migration of moisture, oxygen and other gases, volatile fragrance, and light than any plastic laminate material. Recently, plastic-derived products have become a vital commodity for various purposes. It has three reflecting materials for comparison of reflectivity; first the typical surface readings, then the different reflective materials at various irradiance levels. A white paint reflector, plastic film, and aluminium foil sheet components are used. The aluminium foil sheet material has a high power density of 1000W/m2 in Standard Test Conditions. Aluminium foil sheet is a highly reflective material with a maximum voltage of 38 V and a maximum current of 12.3A. This enhances the power of the reflective material 466W. The regular surface increases the power by 1.166%, whereas the aluminium foil layer increases the maximum power by 1.3%.
