Monocrystalline Cell: The cell is laminated with 2 EVA sheets, one Tedlar sheet and 3mm tempered glass under 180 °C homogeneous temperature and under vacuum effect. The size of the monocrystalline cell is 52×52 mm² or 31x31mm².

Sensor Box: It is an UV protected aluminum box. The sensor box has two opening access and the mounting holes on its sides are for easy site installation. There are three options for IP Class; IP54, IP65 and IP68. For ventilation purpose, there are 1mm holes at bottom side of the box, or a ventilation plug on its side.

Things you should know about the Irradiance Sensor with Analog output

SEVEN Sensor Solutions, as a weather station supplier, produces two types of irradiance sensors: one with a Modbus RTU output and other with an analog output.

SEVEN’s Analog Irradiance Sensor

In general, analog sensors produce a continuous output signal or voltage that is usually proportional to the measured quantity. Physical quantities such as temperature, velocity, pressure, displacement, strain, etc. are all analog quantities because they tend to be continuous in nature.

The SEVEN Irradiance Sensor, with Analog output, is a weatherproof junction box made of UV-resistant materials. It is made from a monocrystalline solar cell connected to a high-precision shunt. It contains an analog output which is used to measure the radiation value in solar power plants by plugging into analog input dataloggers.

The Analog irradiance sensor is mounted in such a way that it receives solar radiation straight from the sun. It must therefore be aligned with the photovoltaic panels in order to obtain the same measurements. The height at which the photovoltaic pyranometer is mounted is not critical for the accuracy of the measurement. SEVEN sensor Solutions provides an irradiation sensor with mounting brackets on both sides, so that it can be flexibly mounted on the solar panel, no matter where it is located.

Brands that use SEVEN’s analog irradiation sensor

The SEVEN analog radiation sensor is used for SolarEdge because it is compatible with their Gateway and all other dataloggers with analog inputs.

Our engineers, as part of SEVEN Sensor Solutions, are available to assist customers with remote setup service and information on anything they may need.
