STR-21G-S1 Solar Monitoring Systems

EKO’s new solar Monitoring System, called STR-21G-S1, is a dedicated sensor system to perform the most accurate solar radiation measurements of the three solar radiation components (Direct, Diffuse and Global). It can be easily integrated to any DAQ system, which has multiple analog or digital inputs. With the standard sun-position sensor and GPS receiver built inside the sun tracker the system set-up will be quick and easy.

The STR-21G-S1 system can be freely configured to measure the required Solar radiation components in the most accurate way. Hence a cost-effective solution can be created for every application. In harsh climate environments, the MV-01 ventilator & heater can be used . The MS-57 pyrheliometer has a heated front window to avoid condensation and ice which can affect the measurements.

Global radiation can be composed by the sum of the cosine weighted direct and diffuse. This way the sun tracker with pyrheliometer and shaded pyranometer can provide all three Solar radiation components. Unique to the system, EKO’s radiometers have the ability to sample much faster than traditional solar sensors. Faster sample rates allow the sensor to ‘catch’ more accurately the peak irradiance value under variable atmospheric conditions and lower the measurement uncertainty of one-minute average values.
