40% Light Transmission Solar Glass
40% Light Transmission Solar Glass
Higher-transmission photovoltaic glass — generates electricity while letting 40% of visible light through. For daylit atria, conservatories, façades and BIPV installations where natural light is essential.
Trent Glass 40% Light Transmission Solar Glass is photovoltaic glass that generates electrical power while transmitting approximately 40% of visible light. The higher transmission preserves daylit interiors — ideal for atria, conservatories, greenhouse-style spaces and façades where natural light is essential but solar power generation is also desired.
Key Features
- Thin-film silicon photovoltaic cells laminated between two glass plies
- Power output: approximately 30–45 W/m² (peak) — lower than 10% variant due to higher transmission
- Light transmission: ~40% (daylit interiors preserved)
- Toughened safety glass to BS EN 12150 with laminated PV interlayer
- Visible cell pattern (semi-transparent dotted appearance) — appreciated as architectural feature
- Compatible with grid-tie inverters and battery storage
Ideal Applications
- Atrium roof glazing — daylit + power generation
- Conservatories and orangeries
- Greenhouse and horticultural projects (filtered shade + power)
- North-facing or partially-shaded façades
- Office daylit perimeters
- Restaurant and café canopies
- Pedestrian walkway and pergola structures
- BIPV showcase projects emphasising transparency
