The manufacturing process of the cells that make up the photovoltaic systems and the printed circuits require water in quantity and high quality. This water has to be managed wisely so as not to affect the productivity and the expenses of the plant.

Concentrating Photovoltaics (CPV) is driven by only direct solar radiation. To quantify the energy efficiency of a CPV system the total DNI and direct spectral solar irradiance, called spectral DNI, can be measured. Solar sensors are crucial during the phase of development and operation. Even at high sunny places, the composition and variability of the atmosphere strongly affects the solar spectral distribution and will impact on the energy yield and the decision on which cell type to use. The pyrheliometer in combination with the spectral radiometer for DNI measurements accurately pinpoint the solar prospect for certain sites, the spectral impact on the performance and efficiency of the module.
