Photovoltaic power generation insulation rubber sheet

What insulator is used in a photovoltaic module?

DUN-SOLAR™ EPE insulation has been developed to be used as an electrical insulator and physical spacer in critical areas inside of photovoltaic modules. PV Back Sheet - The PV back sheet is a photovoltaic laminate that protects the PV module from UV, moisture and weather while acting as an electrical insulator.

What are back-sheet materials for photovoltaic modules?

Back-sheet materials for photovoltaic modules serve several purposes such as providing electrical insulation, environmental protection and structural support. These functions are essential for modules to be safe for people working near them and for the structures to which they are attached.

What is a Dunmore photovoltaic backsheet?

DUN-SOLAR photovoltaic backsheet are designed with various constructions using only the highest quality materials. Dunmore's superior adhesive and laminating technology provides exceptional bonding of all layers in the PV backsheet along with superior UV stability. Typically, PV backsheets can be produced to your thickness requirements.

Why do you need a backsheet for a photovoltaic panel?

Photovoltaic (PV) modules need to be a reliable source of power for 25 years or more, so their components all need to work in concert to ensure the panel continues to perform. Backsheets help do that – they insulate the electrical components of the module, protecting them over their lifetime. Backsheet performance can be analyzed by:

What is the difference between Eva and photovoltaic backsheet?

Photovoltaic backsheets play an important role in protecting solar modules over their lifetime. On the other hand, EVA is an encapsulant for solar Cells/ Modules. It is a copolymer film which acts as an essential sealant of photovoltaic solar modules for ensuring the reliability and performance.

Which encapsulant is best for PV modules?

This paper puts forward the design and composition requirements of back- and front-sheet materials for achieving the highest possible quality performance from PV modules. For PV modules, ethylene vinyl-acetate (EVA) is the dominant encapsulant because it has the best properties possible and is also a very economical solution.
