Application

EKO's Solar Monitoring Stations are suitable for field research and on-site evaluation of solar irradiance conditions at solar power plants (PV, CPV, CSP) and meteorological sites.
The Solar Monitoring Station is used as a reference for fundamental solar energy research studies and contributes to primary development of more efficient solar cells.


Accurate solar energy statistics are necessary to determine the solar power potential and thus whether or not a site is suitable to built a solar power plant. Even in sunny places, the composition of the atmosphere affects the solar spectral distribution which will impact on the energy yield and influences the decision on which cell type to use. Also the ground surface is of great influence. For example, radiation reflects more on snow than on grassland, so the yield efficiency during the year can be different. The SMS will accurately pinpoint the solar prospect for certain sites, taking into consideration all environmental factors that affect solar radiation on the module.


Monitoring a PV system by providing reliable data is a valuable asset with respect to quality assurance. Solar cell and module manufacturers also use the SMS as a reference for life time performance testing on site. Whereas Engineering Procurement Construction (EPC) contractor that build solar power plants use efficiency data provided by the SMS to check if existing and/or implemented solar power plants work according to the manufacturer specifications.
