Among the other products of the range are polyester films, laminated insulation paper products, fiberglass insulating products, and other electrical insulating materials.
Being a solar back film manufacturer, supplier and exporter in India, Harnawa may be able to help the customers in finding suitable PV insulating materials.
What Is Solar Back Film?
Solar back film is a kind of film which is applied on the back side of photovoltaic modules. It constitutes the insulating and protecting layer in the solar panel structure.
For choosing the correct PV film, one needs to ensure that it provides proper electrical insulation without losing its physical properties during processing and functioning. The choice of such film is made taking into account the structure of the module, required electrical insulation, and other factors.
Solar Back Films / PV Films (JBF brand) belong to the category of insulating pressboard and paper products by Harnawa company.
Importance of Solar PV Film in Solar Modules
The operation of photovoltaic modules is done under the sun where varying weather conditions may take place. Thus, it is important that the materials used in the construction of photovoltaic modules must provide appropriate protection and insulation.
Solar back film may help provide:
- Insulation from an electrical point of view
- Protection of the internal parts
- Separation of conductive parts
- Mechanical protection
- Module reliability
- Insulation inside the construction of photovoltaic modules
This depends on the module design and the overall backsheet construction.
Solar Back Film for Photovoltaic Applications
Solar PV film has been developed with applications in photovoltaic module insulation and protection in mind. The film can be included in the backsheet design depending on the specifications of the solar panel manufacturer.
Some of the factors that need to be considered by the manufacturer when selecting the appropriate film are:
- Film thickness
- Performance of electrical insulation
- Mechanical strength
- Dimensional stability
- Moisture resistance
- Temperature specifications
- Compatibility with other layers
- Processing conditions
- Size specifications of the roll or sheet
The selection of the right PV film should depend on the whole solar module design.

Key Considerations When Selecting PV Film
Electrical Insulation
Another factor to consider when choosing the PV film is insulation since the material is one of the components of the electrical structure of the module.
Mechanical Properties
The film must have appropriate mechanical attributes to meet the manufacturing and service demands of the solar module.
Thermal Performance
During operation, there will be changes in temperatures in the solar module. Thus, the thermal demands of the application must be considered when choosing the PV film.
Environmental Resistance
The outdoor solar module may face environmental conditions such as moisture and varying temperatures. Thus, the complete backsheet system must be chosen depending on the operating environment.
Processing Requirements
Film size, thickness, flexibility and compatibility with other materials are other factors that should be taken into consideration during module manufacturing.
