Yuying Fresnel lens for the best sun car

The best sun car:
　　The large-size Fresnel lens produced by Yuying was used for the best sun car on September 7th, 2014 in the CCTV-10 Science and Education Channel's "This is the way" program. Praised by the majority of solar enthusiasts. The largest Fresnel lens currently produced by Yuying is 1.8 meters in diameter and is one of the few manufacturers in the world that can produce large Fresnel lenses. The difficulty in processing large-sized Fresnel lenses is that the lathes that require the processing of the mold have high precision and the lens transmittance is large, and only a high-standard Fresnel lens can collect solar energy with high efficiency.
