Lexsolar Experiment - Large Set

• Key Stage 3: 11 to 14 yrs
• Key Stage 4: 14 to 16 yrs

Students learn the basics of solar energy with exciting experiments using solar cells.

Ideal teaching resource in physics and natural sciences with numerous experiments in electricity and optics. There are students manuals (502-013) available to accompany this kit.

Correlating school physics with practical usage of the photovoltaic cells is a speciality of this system. These uniquely innovative educational systems are the first choice when it comes to experiments related to solar energy, since winning the Worlddidac Award, being the only experiment system in photovoltaic cells. Students` manual available covering 17 different activities.

Experiments possible:

Series and parallel connection of solar cells, dependence of the capacity on face of the solar cell, dependence of the capacity on the angle of incidence, dependence of capacity on level of illumination, determination of efficiency ratio of energy conversion, internal resistance of solar cell, dark characteristic curve of solar cell, inhibiting and conducting direction in illumination and darkness, IV characteristic and filling factor of the solar cell, IV characteristic of the solar cell in dependence on the level of illumination, dependence of the solar cell capacity on temperature, shadowing effect of solar cells in series connection, shadowing effect of solar cells in parallel connection, the solar cell as transmission measure, dependence of solar cell capacity on the frequency of incident light.
