General Description

The Computer Controlled Photovoltaic Solar Energy Unit, "EESFC", includes equipment that uses the photo-conversion law for the direct conversion of 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).

The unit contains:

  • 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.

Optional (NOT included in the minimum supply):

  • EE-KIT. Kit of Conversion and Consumption Simulation (AC): Single-phase inverter. AC Loads Module: 3 Lamps, 1 axial compact fan with plastic guards and 4 positions selector. AC voltage and current sensors.
  • EE-KIT2. Grid Connection Inverter Kit: Grid Connection Inverter. Grid Simulator (ESR).
