STRATO® Solar PV Encapsulants: celebrating years of proven performance and 100% certified Italian excellence

Satinal focuses on superior quality, durability, and architectural freedom with its STRATO® Solar PV Encapsulants range, a trusted choice for solar panel manufacturers and architects worldwide. 

Many developers are learning that low-cost alternatives often come at the expense of long-term reliability. Satinal’s encapsulants, by contrast, have long been established as a field-tested benchmark for PV market. This success is anchored in a commitment to European manufacturing excellence: the entire STRATO® Solar PV range is proudly 100% Made in Italy certified, EPD verified and produced under rigorous ISO 9001 quality management standards.

Efficiency and reliability

In a market often compromised by material degradation and shrinkage, STRATO® Solar PV encapsulants provide the global industry with structural support, electrical insulation, and superior module protection. The core advantage of the line—its exceptional thermal stability—directly addresses the shortcomings of standard Asian imports.

By leveraging Satinal's long-standing manufacturing expertise to eliminate residual tensions during production, these films guarantee negligible material shrinkage during lamination. This allows manufacturers to optimize production cycles and minimize defects.

A European supply chain

Satinal selects its raw materials exclusively from European suppliers, ensuring that its ISO 9001 certified production facility in Italy maintains the absolute highest standards of compliance and traceability—values often lost in global supply chains.

Over years of real-world exposure in severe environmental conditions, these proprietary formulations have proven their absolute Potential Induced Degradation resistance and weathering protection. 

A whole range of encapsulants

Satinal’s goal has been designing a product range capable of covering all needs in terms of applications (both back and front side of PV modules) and long-lasting performance

• STRATO® EVA SOLAR PV

Engineered for long-term backsheet protection, this ultra-fast curing, PID-resistant EVA film features a tailored UV barrier. By blocking harmful ultraviolet wavelengths, it effectively prevents weathering-induced yellowing over the module's lifespan.

• STRATO® EVA SOLAR PV HLT

Optimized specifically for the front side of standard solar panels, this ultra-fast curing, PID-resistant EVA film prioritizes High Light Transmission (HLT). By allowing UV wavelengths to pass through, it maximizes energy capture and boosts overall module efficiency.

• STRATO® POE SOLAR PV

This advanced POE encapsulant combines rapid cross-linking (ultra-fast cure) and excellent PID resistance with a low-UV-transmission profile. It shields the backsheet from solar degradation and weathering, ensuring structural durability.

• STRATO® POE SOLAR PV HLT

Designed for front-face applications, this high-performance POE film pairs PID resistance and fast curing cycles with maximum UV transparency. The enhanced light transmission directly translates to a higher power output for the PV module.

• STRATO® TPO SOLAR PV

A specialized, PID-resistant TPO film formulated to safeguard the rear side of solar panels. Its integrated UV-blocking properties prevent the backsheet from yellowing and degrading when exposed to harsh outdoor elements

• STRATO® TPO SOLAR PV HLT

A front-side TPO encapsulant engineered to optimize solar irradiance. Along with robust PID resistance, its high UV transmittance allows more light to reach the solar cells, significantly enhancing the panel's overall performance

• STRATO® EPE SOLAR PV: a co-extruded multilayer encapsulant film engineered specifically for advanced solar photovoltaic modules. It features a three-layer sandwich structure, a configuration that combines the exceptional cross-linking and glass-adhesion properties of EVA with the superior moisture-barrier and electrical insulation capabilities of POE

ColorQuant™ Technology

Satinal’s role in reshaping urban landscapes is well-established, solving the design limitations of traditional blue and black panels with its STRATO® EVA Solar PV ColorQuant™ technology.

For years, ColorQuant™ has allowed architects to integrate solar power into standard building facades and rooftops using a palette of colours, including green, dark grey, light grey, and terracotta. By utilizing advanced photonic layers that only reflect the specific visual light needed for colour impression, the technology avoids the massive efficiency losses of traditional coloured overlays. 

A proven track record for tomorrow’s net zero buildings

With landmark architectural projects already utilizing Satinal’s technologies globally, the STRATO® Solar PV range stands as a fully validated solution for the modern industry. Where standard mass-market alternatives present long-term risks, choosing a 100% certified Made in Italy product guarantees maximum reliability. 

Satinal has spent years proving that clean energy generation can coexist perfectly with structural beauty, safety, and long-term durability.
