RaZON+

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 kilowatt hours/m2. With the Wi-Fi connection you can easily set-up and configure RaZON+ using any smart device, such as a tablet.

Included sensors

RaZON+ includes two Smart irradiance sensors; a pyrheliometer to measure DNI and a shaded pyranometer to measure DHI. The innovative features of the pyrheliometer minimise 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.

RaZON+ measures DNI and DHI and calculates GHI, as this minimises 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, RaZON+ is based on a completely maintenance-free gear drive sun tracking mechanism.

Internal data logging with web access

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, which can also be checked on the spot with a smartphone, tablet or laptop via the optional Wi-Fi connection.

Expand RaZON+ with additional sensors

An extra Modbus® input allows additional sensors to be connected; for PV panel temperature, tilted irradiance or a compact weather station.
