A solar backsheet can be defined as a final component of a photovoltaic (PV) unit employing the role of protecting the built-in solar module peripherals. While selecting the solar backsheets, the frequent used types include; Non-fluoropolymer MB, single fluoropolymer MB, and double fluoropolymer MB, which can be installed on the roof, ground or floating power plants. These backsheets are normally made by polymers or a blend of polymers and are positioned on the lowest part of the photovoltaic module. They are rather wear-resistant and demonstrate high electric non-conductivity alongside with rather good protection against any mechanical threats, dust and chemicals, sand, gusts of wind, low and high temperatures, humidity and UV irradiation.

Solar energy can be defined as the sunlight and the heat that are collected in various forms including solar power, photovoltaic cells as well as solar thermal systems. It is a source of power capable of being regenerate, the energy that can be utilized for electric power or for heat.
