Irradiance, temperature and wind sensors for PV plants
How to choose sensors for solar resource, module temperature and weather conditions without turning the datalogger into a protocol lottery.
What should be measured
Irradiance
It allows available solar energy to be compared with actual production and helps detect losses, soiling or deviations.
Module temperature
It helps explain thermal losses and assess PV generator behaviour.
Wind and ambient conditions
They are useful when module cooling, structure or weather analysis requires additional context.
Available sensors and references
Irradiance + temperature
Measurement device with a laminated solar cell under solar glass, designed to compare solar resource with actual production.
View productIrradiance + temperature + wind
Weather measurement solution for plants that need to correlate production with wind speed as well as irradiance and temperature.
View productPT1000 module temperature
Probe designed to measure temperature on the rear of a PV module and analyse thermal losses and performance.
View productTemperature 4-20 mA
Sensor for integrating rear module temperature into dataloggers, PLCs or monitoring systems with a 4-20 mA analogue input.
View productCompatible with Solar-Log
Reference intended for Solar-Log monitoring systems. Exact compatibility must be checked against the datalogger and project metering architecture.
View productSEVEN Modbus irradiance
Professional sensor for industrial and commercial plants that gathers weather data and transmits it to the datalogger via Modbus RTU.
View productHow to choose correctly
- Confirm which variables are required by the contract, PR calculation or monitoring system.
- Validate protocol and signal: Modbus RTU, PT1000 and 4-20 mA are not magically interchangeable.
- Check supply, distance, cabling, connectors and available inputs.
- Define calibration, maintenance and traceability before commissioning.
Frequently asked questions
Are PT1000 and 4-20 mA the same?
No. PT1000 is a resistive signal; 4-20 mA is a transmitted analogue signal. The datalogger needs the correct input.
Will any Modbus sensor work with any datalogger?
Not always. Register map, speed, parity, address, supply and datalogger configuration must all be checked.
Does a reference-cell sensor always replace a pyranometer?
Not necessarily. It depends on the contract, standard, PR calculation and required accuracy. If a thermopile pyranometer is specified, it must be used.
Do sensors need recalibration?
Yes, when required by the manufacturer, contract or quality plan. Frequency, traceability and certification should be defined from the start.
Not sure which sensor fits?
Send us the datalogger, diagram and variables you need to measure. We will help validate compatibility before material is ordered.
