Concentration PV Plants

Solar tracking PV technology is suitable for areas of medium to high irradiation. Years of experience and more than 7 GW installed worldwide demonstrate the proven reliability and performance of this technology. Additionally, tracking PV systems are used by various markets because of their distributed energy potential and low maintenance costs. Concentrated PV is based on the same concept as regular PV, but optics are used to concentrate solar energy and reduce the amount of PV cells needed.

  • Photovoltaic: Modular and Distributed
    PV technology can satisfy any type of electricity requirement, small or large, because of its modularity and distributed capabilities. Because they are modular, PV systems can be built for large plants or small customized installations. Because it has distributed capabilities it can provide electricity in areas where no grid connection is available.
  • Photovoltaic: Easy building integration
    Recent advances in semiconductor technology have expanded the usefulness of PV systems for buildings. While single-crystalline silicon semiconductors are typically used on roofs of buildings, thin film technology makes it possible to install PV systems as part of windows and facades.

The technology that Abengoa Solar installs with its low concentration PV systems, Sevilla PV , and high concentration systems is proprietary.

The technology

Concentrated PV plants use optic elements to concentrate solar radiation incident to a PV cell. Since concentration greatly reduces the are of solar cells needed, more expensive semiconductors like GaAs or high efficiency Si are used to maximize performance.

Low concentration PV plants often use mirrors to concentrate solar radiation onto a PV cell. Abengoa Solar often uses high efficiency Si in their low concentration PV installations. High Concentration PV plants use optical technology and lenses to concentrate solar radiation up to 500 times. Since this greatly reduces the area of PV cells needed, more expensive and higher performance semiconductors like GaAs are often used.
