The Solar Cell Base System is a comprehensive educational platform designed for learning and experimenting with solar energy and its various components. This system includes monocrystalline silicon solar cells that serve as the core component for experiments, providing valuable hands-on experience with solar energy conversion. The solar cells have specific parameters like an open-circuit voltage of 1.5V, a short-circuit current of 2.3A, and a maximum power of 1.1W per unit. These solar cells are paired with a self-contained trainer unit capable of adjusting solar irradiation and azimuth for simulating sunlight, allowing for experiments under varied conditions.
The system features a halogen lamp as a light source to simulate sunlight for the solar cells, with adjustable brightness and a beam angle of 60°. This is supported by a dimmer for regulating the light intensity, with input options for both 110VAC and 220VAC and an output of 12V. The Digital Multimeter included in the setup is essential for measuring DC and AC voltage, current, resistance, and more, offering a range of input and output resistances and providing accuracy for testing and calibration. The energy storage options include NiMH rechargeable batteries and super capacitors for storing energy generated during experiments.
A DC motor and light bulb are included as loads to demonstrate the energy output from solar cells, and the potentiometer allows for variable resistance testing. The system also features an Inverter with an output of a square wave at 2Vpp and 50/60Hz frequency, converting DC to AC.
The system is powered by an AC power supply (110/220 VAC), with a 15VDC output for testing. The DAQ (Data Acquisition System) is integrated for collecting and saving experimental data, supporting software for Windows XP, Vista, 7, and 8, and ensuring that the experiments are recorded accurately for analysis.
Additional accessories such as test leads, shading plates (25%, 50%, 75%, 100%), and a solar power meter are included for measuring irradiation and energy conversion efficiency. The Solar Power Meter offers a detailed readout, with a resolution of 0.1 W/m² and an accuracy of ±10 W/m². Experiments include measuring solar cell irradiation, energy conversion efficiency, current-voltage (I-V) curves, and simulating real-world conditions like daily sunlight variation and shading effects.
The system comes with a 5-day training package and a 2-year warranty, ensuring that users can set up, operate, and maintain the equipment effectively. This system is designed for educational use, providing valuable insights into solar energy principles, energy conversion, and the practical application of solar technologies.
