RaZONis an innovative ALL-IN-ONE solar monitoring system with integrated pyrheliometer, shaded pyranometer, digital data processing, GPS receiver and data logger. It measures direct normal irradiance (DNI) from the sun and diffuse horizontal irradiance (DHI) from the sky and, knowing the sun position calculates very reliable values of global horizontal solar irradiance (GHI). From the DNI measurements, sunshine duration is calculated very accurately. It is designed for remote locations being resistant to soiling and with the Wi-Fi connection can be easily set-up and configure using any smart device.
