High-Efficiency Silicone Glass Fresnel Lens | Ideal for Solar Thermal and CPV Systems


Ideal for Solar Cookers, Collectors & Concentrated Photovoltaics (CPV)


Our Solar Fresnel Lens is specially designed for solar concentration systems such as CPV, solar cookers, and solar thermal collectors. It adopts a reverse configuration, where the flat side faces the sun and the grooved side focuses the light onto the photovoltaic cell or heat collection point—maximizing sunlight utilization.

Unlike traditional imaging lenses, solar Fresnel lenses don't require high image quality. This allows for lower groove density, creating a larger effective surface area and improving solar concentration efficiency.

Combined with ultra-white tempered glass and high-precision silicone molding, our lens ensures excellent UV resistance, weather durability, and light transmittance, even in harsh outdoor conditions.



Technological and Manufacturing Advantages


Yuying is equipped with multiple advanced single-point diamond turning machines, capable of producing giant Fresnel lenses with diameters up to 2.2M. With exceptional mold quality and leading-edge processing technology, Yuying’s products rank among the best in the global market. Yuying offer customized designs for Fresnel lenses based on customer requirements, including concentration ratios and solar panel dimensions, ensuring optimal light concentration effects. Our products are widely used in solar power stations, outdoor solar cooking devices, and other applications.





Material and Structural Design


The Fresnel concentrator lens is made of glass-based silicon material and is typically integrated with solar panels in a modular design to achieve optimal performance. To ensure long-term stability in harsh outdoor environments, the lens uses ultra-clear tempered glass as the substrate and is formed with silicone gel molding technology. Its unique fine-thread molding process ensures high refractive index and low optical loss, while also providing high strength, high light transmittance, aging resistance, UV radiation resistance, and excellent weather adaptability, significantly improving the power generation efficiency of solar cells.


Customized Solutions


We can precisely design the edge dimensions of the Fresnel lens and the distance between the lens and the solar panel based on the customer's concentration ratio and solar panel size, ensuring optimal light concentration. Additionally, we recommend integrating the Fresnel lens into a photovoltaic power generation system equipped with a solar tracker to maximize energy capture efficiency.
