Applications:
Solar Low-E Glass can be used in the following aspects:
1. Superstrate of Thin-film Solar Panels
With higher solar light transmittance, it can improve the photoelectric conversion efficiency of the solar cells.
2. Flat Solar Collectors
With higher visible light transmittance, it can improve the photo-thermal conversion efficiency of the solar collectors.
3. Solar Mirrors
Take full advantage of extremely high reflectivity of the ultra clear glass mirror to improve the thermal efficiency, thereby to enhance the overall efficiency of thermal power generation.
4. BIPV Project (Building Integrated Photovoltaic)
In the BIPV project, Solar Low-E Glass (and TCO glass) can be used for both front-panel glass and seal glass of the thin-film solar cell. In photoelectric curtain walls, Solar Low-E Glass can not only satisfy the requirements of indoor lighting but also help the photovoltaic efficacy of power generation, it will be the main development trend of future buildings.
5. Greenhouse Glass
Solar Low-E Glass can accelerate the plants’ photosynthesis and shorten the growth period, help clients gain more economical benefits.
