phiNet20

I-V curves measurement of photovoltaic modules

INSTALLATION

 

The equipment is installed in the field and has a fast response after sales service. The facilities can be designed according to the needs of the clients

 

REPORTS

 

The measuring stations are connected to the phiNet® platform where you can download the PDF reports of the measurements made in the field, as well as being able to download the data in CSV for further analysis

 

ANALYSIS AND FOLLOW-UP OF PHENOMENA ASSOCIATED WITH THE OPERATION OF PHOTOVOLTAIC PLANTS

Detection of cracks in photovoltaic cells, phenomena of decay of energy production associated with the degradation of photovoltaic modules, advanced studies of the degradation of modules due to phenomena associated with the operation of the photovoltaic plant.
Monitoring and control of hot spots in the photovoltaic modules, historical record of the I-V curves of photovoltaic modules affected by high heating due to the operation of the strings.
Measurement of the deposition of dust and other contaminants on the surface of photovoltaic modules. Monitoring and control of dust deposition by comparing the reduction of production from a reference module. Advanced studies in the photovoltaic plant for optimal maintenance planning.

 

 

MAIN FEATURES

  • Measurement of electrical parameters (<500W STC): current [A] and voltage [V].
  • Obtaining I-V and P-V curves for different solar radiation and temperature conditions every 10 minutes.
  • Obtaining the Maximum Power Point of each measurement.
  • Measurement of solar radiation in inclined plane (GI) [W / m2], temperature of the photovoltaic modules, ambient temperature, wind speed and direction in each reading of the electrical parameters of the modules.
  • Transmission of data to the phiNet® platform hour by hour. Visualization of the data in graphic form.
  • Reports in PDF of the measurements.
  • QR code printing for the identification of photovoltaic modules.
  • Historical monitoring of the measurements of each module (life history).
  • phiNet®20 system with transportable system in IP67 case, includes main accessories for field measurement.

MEASUREMENT OF VOLTAGE AND CURRENT IN PHOTOVOLTAIC MODULES

phiNet®20 has a high-precision voltage and current measurement system that allows the measurement of up to 4 photovoltaic modules simultaneously. The following graphs show an example of the maximum power measured every 10 min (left) and a graph of the I-V curves of one of the points measured for 3 modules of different technologies.

Database of measurements

  • Creation of a QR code for each photovoltaic module
  • Comparison of the information of the electrical parameters of the modules during the useful life of the photovoltaic plant (25 years)
