Big Solar Fan Model
Product Code : SCL-EAE-11293
Quick answer: The Big Solar Fan Model is a large-format classroom demonstration in which light on a photovoltaic panel produces electricity that drives a motor and turns a fan. It shows the chain from light energy to electrical and then mechanical energy, and how light intensity and panel angle affect fan speed. Lab Exports manufactures it in Delhi for schools and colleges.

How the model is used in teaching
A solar cell is a large-area p-n junction. Light absorbed near the junction frees charge carriers, and the built-in electric field drives them round an external circuit as a current. In this model that current feeds a DC motor whose shaft carries the fan blades, so the energy chain from light to electrical to mechanical energy is visible in one set-up.
The large format lets a whole class watch at once. Shading part of the panel, moving the light source or tilting the panel changes the fan speed, which leads naturally into discussion of light intensity, panel orientation and why solar installations are angled towards the sun.
- Place the model on a stable, level surface.
- Check that the panel, wires, motor and fan are firmly attached.
- Point the solar panel towards direct sunlight or a suitable light source.
- Watch the fan start, then change the panel angle or shade part of it and compare the speed.

Frequently asked questions
What does the big solar fan model demonstrate?
It demonstrates photovoltaic energy conversion: light on the solar panel produces electricity, which runs a motor and turns the fan, showing light energy becoming electrical and then mechanical energy.
Does the solar fan need sunlight?
The panel can face direct sunlight or a suitable light source. The fan speed depends on how much light reaches the panel, so a weak source gives slow or no rotation.
