The Fresnel lens is an essential optical element of the Concentrate photovoltaic. Using the Fresnel lens, you can create a wide area of light collection and reduce the electric consumption of the drive unit due to light lenses.

Fresnel lenses used in CPV require the following precautions.

  • Concentrated light efficiency
  • Temperature Heat Resistance
  • Penetration Ratio
  • UV Tolerance

 

Fresnel Factory develops and supplies home-use panels using polymer, glass, and Film materials.
Can collect sunlights using linear, single, and multi-array.

Concentrated photovoltaic cells (CPV ) are photovoltaic technologies that generate electricity from sunlight. Unlike conventional photovoltaic systems, we use lenses and curved mirrors to focus the sun's light on small but highly efficient multi-junction (MJ) solar cells. The CPV system also often uses solar tracer and, in some cases, cooling systems to increase efficiency. [2] : 30 The ongoing research and development is rapidly improving competitiveness in the power business sector and in high areas. This kind of solar technology can be used in smaller areas.

Fresnel Factory supplies photovoltaic, solar-powered lenses. The light collection method is known as the Concentrat Photovoltaic (CPV).
This method is used not only for power generation but also for natural lighting, which is used for indoor lighting by collecting light from outside.
Photovoltaic lenses have Silicon-on-Glass (SOG) lenses designed to withstand temperatures of more than 160 degrees Celsius and common PMMA lenses. It is also divided into single-array and multi-array lenses.

 

SOG태양광 발전 특징

SOGs (Strengthen glass silicone metal lenses) and convergent solar cells are designed in a Box format for best effect. Using multi-arranged Fresnel Concentration Lens, the solar array is designed for a wide variety of external environments and is available outdoors for long periods of time. Using the Silicone Gel mold to attach a high-precision, thin silicon lens to the Ultra-white reinforced glass surface. The benefits of SOG lenses are as follows: 

  • Ensured high refractive index
  • Thermal Resistance
  • Durability
  • Minimize optical losses
  • High-intensity
  • Transmittance and anti-aging
  • Anti-ultraviolet radiation

 

SOGs have relatively stronger climatic resistance characteristics than optical PMMA (Optical Acrylic). Especially, it has excellent characteristics for high-temperature resistance and deformation required in concentrated solar power. For continuous exposure to heat, SOG products can be used with no deformation of the lens up to 180°C PMMA material. Fresnel Factory provides a variety of customization, including lens size, angle of incidence, lens and solar panel distance modification, depending on the customer's needs.
