Invention

This technology is a multi-detector solar irradiance sensor design which can measure both direct and diffuse light in a variety of conditions. Additionally, this device provides real time angular distribution measurements of the anisotropic diffuse illumination incident on solar electric panels.

Background

Photovoltaic systems are designed and tested based on standard conditions in which only direct incidence and isotropic diffuse illumination are considered. However recent tests done at the TEP solar testing beds have shown that anisotropic diffuse illumination can be used to more accurately predict PV system performance. Many sensors only measure direct illumination, and ignore diffuse illumination, or measure both at a limited range of distribution.

Advantages

  • The ability to provide live angular distribution of the diffuse illumination.
  • No tracking or motors of any kind are required on this device
  • It can be used with any type of solar panel (both traditional flat plane panels,
  • Can be used in new breed of bifacial, holographic planar concentration (HPC) and cylindrical non-standard flat PV technologies.)

Application

  • Can be incorporated into the testing of all solar panel companies products.
  • Could one day be developed and sold as a testing upgrade for better predictability of performance and results in future solar panels
  • Technology is for both for individual buyers and major companies.
