Development of the SunCycle solar concentrator

Why SunCycle?Best Research Solar Cell Efficiencies

III-V Solar cells

Why concentrators?

1. Replacing semiconductor material by cheap components

2. High efficiency by using III-V solar cells

3. Resulting in a lower cost per kWh

Examples of concentrators

Mirrors in Australia Lenses in Spain

Concentrator - issue

To follow the moving sun, a heavy and accurate tracking system is required:

it is costly and can not be applied in the residential area

SunCycle solved that issue

One axis tracking allows for a static structure→ installation in the residential area→ thermal energy applications

How does it work?

How does it look?

Traditional tracking CPV system

SunCycle’s solution: internal tracking

Production of the components

III-V cell: commercial available

Injection molded housing components

Mirror:injection molded PC; aluminum coated

Prism:injection molded PMMA; Solar Grade

The components are comparable to those in headlamps of cars :The function is inverse.

Benefit for the customer

thermal energy ideal for sunny,residential areas

well recyclable;low EPBT

high electricalefficiency
