DESC:FIELD OF INVENTION
[001] The field of invention generally relates to solar power. More specifically, it relates to a system and method for enhancing albedo for bifacial solar panel.

BACKGROUND
[002] Renewable energy, often referred to as clean energy, comes from natural sources or processes that are constantly replenished. Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, rain, tides, waves, and geothermal heat.
[003] One such renewable energy is sunlight, or commonly known as solar energy. Solar energy is the radiation from the Sun capable of producing heat, causing chemical reactions, or generating electricity. Solar energy can be harnessed for human use using solar panels and convert the solar energy into electricity. A solar cell panel, solar electric panel, photo-voltaic (PV) module or solar panel is an assembly of photo-voltaic cells mounted in a framework for installation. Solar panels use sunlight as a source of energy to generate direct current electricity. A collection of PV modules is called a PV panel, and a system of PV panels is called an array. Arrays of a photovoltaic system supply solar electricity to electrical equipment.
[004] Over the last years, solar panels have been developed to capture maximum sunlight, such as bifacial module. The bifacial modules can generate energy from the front and rear side of a module. Unlike mono-facial modules, the rear side of bifacial modules is lined with cells to capture reflected and diffused irradiation. In order to capture sunlight from rear side of the module, a sheet is fitted on the sheet which helps in reflecting the sunlight which hits the ground to be captured by the rear side of the module.
[005] However, bifacial modules come with issues over long term which hinders sunlight from being captured from the rear side of the module due to the placement of the sheet. The issues are including but not limited to, sheet deteriorates upon contact with soil, dust/soil deposition over the sheets laid on ground leads to lower reflectivity and will necessitate frequent cleaning and rainwater flow may lead to washing away of the sheets, deposition of soil and damage due to debris.
[006] Therefore, in order to overcome the aforementioned issues, there is a need for a bifacial module which overcomes the aforementioned issues.

OBJECT OF INVENTION
[007] The principal object of this invention is to provide a sheet to be hung from the solar panel.
[008] A further object of the invention is to hang the sheet from the rear of the solar panel.
[009] Another object of the invention is to suspend the sheet from the rear of the solar panel to be hung for a predefined height at a predefined angle and at a predefined distance from ground.
[0010] Another object of this invention is to provide the sheet composed of poly propylene.
[0011] Another object of this invention is to enhance albedo and to enable maximum capture of solar energy.
