RSB-01 Rotating Shadow Band

For spectral measurement of the three irradiance components (DNI, GHI, DHI) we took a different approach. A spectroradiometer with rotating Shadow Band (RSB) is an attractive alternative to a conventional 3 component sun tracker system. Just one spectroradiometer used for all measurements lowers the costs associated with the instrumentation required. Accurate DNI measurements can be obtained from a MS-711 Global spectroradiometer with RSB comparing with the MS-711 DNI spectroradiometer on a sun-tracker. The comparison between the outputs spectral DNI from the two configurations reveals a consistency in the method and the measuerements of all 3 irradiance components. EKO will provide the RSB solution for all spectroradiometer models.
