Razon+ : All in one Solar Monitoring system

![]() |
Important features :
|
The RaZON+ is an all-in-one system that accurately measures both direct normal irradiance (DNI) and diffuse horizontal irradiance (DHI) from the sun and sky, enabling it to provide very reliable values of global horizontal solar irradiance (GHI) and sunshine duration.
The integrated data logger presents the irradiance measurements in W/m², sunshine duration in hours and energy in kWh/m².
Included sensors :
The RaZON+ includes two Smart irradiance sensors; a pyrheliometer (PH1) to measure DNI and a shaded pyranometer (PR1) to measure DHI. The innovative features of the pyrheliometer minimize the effects of soiling when operated unattended in remote locations, without compromising the high accuracy of the instrument. Both the pyrheliometer and pyranometer are based on quartz diffuser technology.
The RaZON+ measures DNI and DHI and calculates GHI, as this minimizes uncertainty in the pyranometer readings and provides a more accurate and reliable measurement than using an unshaded pyranometer to measure GHI.
Anti-soiling & low maintenance :
Thanks to the open collimator tube design and the quartz diffuser, the pyrheliometer is resistant to the effects of soiling. Moreover, the RaZON+ is based on a completely maintenance-free gear drive sun tracking mechanism.
Internal data logging with web access :
The RaZON+ comes with internal data logging of all parameters in one data set. Choose either the Ethernet or RS-485 interfaces (Modbus® RTU or ASCII) to download your data.
The data is presented in a complete interface with data, graphs and status information.
Expand RaZON+ with additional sensors :
An extra Modbus® input is fitted, which will allow additional sensors to be connected with future updates; for example PV panel temperature, tilted irradiance or a compact weather station.
