Computer Controlled Photovoltaic Solar Energy Unit

The Computer Controlled Photovoltaic Solar Energy Unit, “EESFC”, includes equipment that uses the photo-conversion law, which directly converts solar radiation into electricity. The absorbed energy is provided by simulated solar radiation, which in our case is supplied by a panel with powerful light sources (solar lamps).

This unit is composed of:

  • Photovoltaic solar panels.
  • Solar simulator composed of solar lamps.
  • Ventilation system.
  • DC load and battery charger regulator.
  • Auxiliary battery charger.
  • Battery.
  • DC loads module.
  • Sensors (temperature, light radiation, DC current and DC voltage).

This Computer Controlled Unit is supplied with the EDIBON Computer Control System (SCADA), and includes: The unit itself + a Control Interface Box + a Data Acquisition Board + Computer Control, Data Acquisition and Data Management Software Packages, for controlling the process and all parameters involved in the process.

Category: Product ID: 14276

  • Ventilation system, computer controlled, that allows to analyze the temperature influence on the unit operation.
  • DC load and battery charger regulator.
  • Auxiliary battery charger.
  • Battery.
  • DC loads module.
  • Sensors.
  • The connection of solar panels in parallel or series, the measurement of the voltage and the current before or after the regulator and the regulation of the light intensity of lamps of the two independent circuits are computer controlled.
  • The unit includes four blinds to reduce a direct visual contact with the halogen lamps and to reduce the direct contact with the photovoltaic solar panels when the unit is working.

The complete unit includes as well:

  • Advanced Real-Time SCADA.
  • Open Control + Multicontrol + Real-Time Control.
  • Specialized EDIBON Control Software based on LabVIEW.
  • National Instruments Data Acquisition board (250 KS/s, kilo samples per second).
  • Calibration exercises, which are included, teach the user how to calibrate a sensor and the importance of checking the accuracy of the sensors before taking measurements.
  • Projector and/or electronic whiteboard compatibility allows the unit to be explained and demonstrated to an entire class at one time.
  • Capable of doing applied research, real industrial simulation, training courses, etc.
  • Remote operation and control by the user and remote control for EDIBON technical support, are always included.
  • Totally safe, utilizing 4 safety systems (Mechanical, Electrical, Electronic and Software).
  • Designed and manufactured under several quality standards.
  • Optional ICAI software to create, edit and carry out practical exercises, tests, exams, calculations, etc. Apart from monitoring user’s knowledge and progress reached.
  • This unit has been designed for future expansion and integration. A common expansion is the EDIBON Scada-Net (ESN) System which enables multiple students to simultaneously operate many units in a network.
