What is a solar backsheet?
Backsheets are the outermost 鈥渓ayer鈥� for a solar panel, the first line of defense for solar cells. 听They play a critical role in protecting solar panels from harsh, varying environmental conditions over panel lifetimes.
Not all backsheets are created equal. In order to protect a panel for more than 25 years, a backsheet must have the optimal balance of three critical properties: weatherability, mechanical strength and adhesion. These properties must be maintained over the service life of the module.
Backsheet related failures can lead to catastrophic breakdown of panels, significant power degradation and severe safety hazards. The impact can be significant, ranging from severe brand and reputation losses to bodily harm.
Tedlar庐 PVF film-based backsheet is the industry standard for solar backsheets
Tedlar庐 PVF film-based backsheet designs have been in the field for more than 30 years in different climates, including deserts, tropical locations, seashores, and mountainous terrains. They have protected millions of solar panels across multiple geographies.
It is only Tedlar庐 backsheets, which are field proven and have demonstrated critical, long-life panel performance, protecting the system and enabling long-term returns.
Tedlar庐 TPT Backsheet
- In harsh climates, it offers the best protection from UV, thermal, moisture, mechanical and chemical stress
- Inner Tedlar庐 PVF film is more stable under heat and UV exposure than single-sided tie layers
Tedlar庐 TPE Backsheet
- Critical outer layer features Tedlar庐 PVF film that has protected solar modules for more than 30 years
- It offers the best balance of properties in single-sided backsheets for general-purpose applications
Tedlar庐 based backsheets provide critical, long-life protection to the module, safeguarding the system and enabling long-term PV system returns.
