The mono-crystalline solar panel has a maximum rating of 4.4V, 90mA. It can be easily energised by a bright lamp or sunlight. Students can explore the behaviour of the solar cell:. Investigate how the output voltage varies with the area of cell exposed to the light. Use filters to investigate how the output voltage varies with colour/wavelength of light. Use a light meter and investigate how the output voltage varies with light intensity. Determine the optimum electrical load for maximum power transfer for a known light intensity. Determine how the maximum power varies with the light intensity when the electrical load is fixed.
