Ask Tamar…how does a solar panel work?

A timely question. Photons, particles of light, hit the solar cells on the panel made from silicon and which is split into two layers - positive and negative.
These photons 'excite' electrons that are at the negative side by giving them energy. Their newly found energy propels them from the negative side of the metalloid to the positive side (opposites always attract). The electrons begin to flow around the circuit, causing an electric current. Voila! You have solar power - the most renewable form of energy existing today.  
PS The difference between silicon and silicone? Another day...
