Energy Innovation has came up with new product using fresnel lens
I came to this article about the Sunflower’s Fresnel lens . Those lens concentrates sunlight more than 1,000 times, enabling cheaper electricity than traditional photovoltaics. The system is self-powered.
Technical specifications:
- 200-watt system
- features trackers that shift with the sun’s location, as well as a controller and communications system.
- The low-slung Sunflower is built to withstand winds, and it doesn’t need to penetrate a rooftop for installation.
The Sunflower produces more energy over the course of the day than a traditional PV system of equal capacity. This extra energy is particularly helpful in making a system more cost-effective, as the cost of utility-supplied electricity the system is displacing during afternoon “peak” periods is often substantially more expensive than at other times of the day.
The entire system can rotate on 2 axis to be as efficient as possible.
