Silicon Irradiance Sensor, PV Reference Cell and Photovoltaic Pyranometer, Three Names for the Same Device

In the solar energy industry, it’s common to come across different terms that all seem to describe the same thing. Three such terms are Si irradiance sensor, photovoltaic pyranometer, and PV reference cell. While they may sound like different devices, they all refer to the same basic concept: a sensor that measures the amount of […]

A photovoltaic systems manteinance bordering on perfection

It is already the 6th year that we have the Silicon irradiance sensors( PV reference cell) for an O&M in Foggia that manages 60 MW of plants: the ones managed by them stand out by the performance (around 84% and more) of the plants. Plant maintenance – the approach is always consistent Their approach remains […]

PV Reference Cell (Silicon Irradiance Sensor) Vs Thermopile Pyranometers

What Is a Pyranometer? In photovoltaic monitoring, a solar irradiance sensor is a device that measures the solar power (irradiance) falling on a surface. This measurement is essential because the performance of a PV system depends directly on how much sunlight it receives. Depending on their sensing technology, pyranometers are divided mainly into two categories: […]

What is an Anemometer?

Anemometers are instruments that measure wind speed. Users can employ it in different installations, like for example for the management and monitoring of wind farms, weather stations, photovoltaic plants, ski lift, highways, viaducts, high routes & airports. In most applications, users equip anemometer with anti-icing system. TYPES OF ANEMOMETERS Based on the operating principle they are […]

It is unbiased and independent of the manufacturer. The infographic also has scope in the studies of plant and weed growth, solar farm management and meteorology. Use this infographic on […]

How do thermopile pyranometers work?

The physics behind the thermopile pyranometer Solar radiation can be measured according to the Seebeck effect. This thermopile effect is part of a physical phenomenon called thermoelectric effect, in which the temperature difference between two dissimilar electrical conductors produces a voltage difference. The potential difference between the two conductors kept at different temperatures is defined as the […]

Calibration vs. Adjustment, Accuracy vs. Precision: What’s the Difference?

Calibration and adjustment are two similar processes that are often confused and wrongly used interchangeably. This article aims to clear up the differences. The difference between Calibration and Adjustment The National Physics Laboratory clearly explains the key differences between CALIBRATION and ADJUSTMENT: The procedure is: Metrologically speaking, the International Vocabulary of Metrology, V.I.M ed.3, gives […]

Find Out How to connect a sensor with 4-20 milliamps output to a Datalogger/PLC

4-20mA output sensors are widespread in the world. This is because the output in ‘current loop’ is the most robust and reliable kind of analogical output. When signal precision is needed, or datalogger-to-sensor distances are over 18m, or in case of electromagnetic disturbances, it’s necessary to use a sensor with output in current loop. On the […]
