Fresnel lense is one of the key components of CPV(Concentration photovoltaic) and TPV(thermal photovoltaic) system. It faces to the sun light vertically, and concentrates the sun ray onto a small receiver(high performance solar cell), CPV generates more than 30% electricity than conventional FPV(flat photovoltaic). Benefits: Durable in outdoor surroundings High efficiency, low absorption of mid-far infrared ray Applications: Solar energy concentration Photovoltaic CPT (concentration photothermic) TPV (thermal photovoltaic) Customization: Can make up to dia. 2m You can order: Fresnel lens design, trial-manufacture and mass production.
