The Greater London Authority’s (GLA) London Plan 2021 has codified aggressive decarbonization pathways, aiming for London to be a net-zero carbon city by 2030. Achieving this target requires building-integrated photovoltaics (BIPV) and high-performance commercial solar facades to transform the urban skyline. Unlike rural solar farms, urban solar energy relies heavily on advanced material integration—specifically PVB and SGP architectural photovoltaic films that can withstand dynamic structural loads, high wind shear, and strict fire safety requirements (BS EN 13501-1 Class A/B).
As a result, London-based project developers, facade engineering firms, and regional manufacturers are demanding highly reliable supply chains for polymer solar films. The focus has moved from simple light transmission to long-term encapsulation stability, preventing Delamination and Potential Induced Degradation (PID) over 25 to 30 years of severe maritime exposure.
The global and European solar module market is experiencing a rapid technological evolution. For years, Ethylene Vinyl Acetate (EVA) was the industry standard due to its low processing costs and excellent optical properties. However, the rise of N-type TOPCon and HJT solar cells has highlighted EVA's limitations—specifically its tendency to release acetic acid under thermal and humid conditions, which corrodes silver grids and degrades cells.
Polyolefin Elastomer (POE) films have emerged as the ideal solution, offering outstanding water vapor transmission resistance (WVTR) and zero risk of acid release. However, POE's narrower laminating window can sometimes reduce throughput. GWELL's co-extrusion technology bridges this gap with EPE three-layer co-extrusion film lines. This design integrates the mechanical stability and low cost of EVA on the outer layers with the high resistance of POE in the core, providing London and UK PV modules with premium durability and cost-efficiency.
Structural stability is paramount for skylights, glass railings, and curtain walls in London's commercial districts like the City of London and Canary Wharf. Traditional EVA lacks the tear strength required for structural safety glazing. SentryGlas Plus (SGP) ionoplast interlayers and specialized BIPV PVB films offer up to 100 times the stiffness and 5 times the tear strength of traditional PVB, ensuring that the glass envelope remains structurally sound even in the event of glass breakage. Developing extrusion machinery that handles these high-viscosity resins requires high-torque gearboxes and advanced screw configurations to achieve zero-defect optical clarity.
Our solar extrusion lines are built with smart diagnostics and high-performance components to maximize uptime and thickness accuracy.

Detailed insights from our head of polymer engineering on the processing and deployment of solar encapsulation film technology.
Pre-crosslinking is prevented by maintaining a low processing temperature (below 105°C) and implementing an optimized screw profile design. We utilize co-rotating screws with special barrier segments that offer efficient melt distribution and low shear heat. Additionally, the liquid peroxide crosslinking agent and silane coupling agent are injected directly into the barrel via high-pressure micro-metering pumps to guarantee uniform compound distribution without thermal hot spots.
POE (Polyolefin Elastomer) has a water vapor transmission rate (WVTR) that is roughly two orders of magnitude lower than EVA. It possesses superior electrical resistivity, preventing Potential Induced Degradation (PID) in high-voltage bifacial N-type modules. Moreover, POE does not undergo hydrolysis to release acetic acid, thereby protecting the silver busbars from corrosion and ensuring a module lifespan exceeding 25 years.
Our SGP and PVB architectural BIPV lines are integrated with automated T-dies containing dynamic thermal-expansion bolts. Working in a closed-loop feedback system with a non-contact beta-ray gauge, the system continuously adjusts the die opening profile. This maintains the web thickness tolerance within a strict ±0.01mm limit across the entire width of the film, which is critical for optical clarity and bubbles-free lamination.
Standard delivery timelines for large-scale lines range between 90 to 120 days. This includes CAD layout alignment, custom manufacturing of the extruder barrel and screw, electrical integration, and dynamic test running with raw material at our production bases. All machinery shipped to the UK complies with UKCA/CE markings and is securely crated for maritime transport.
