Solution
The best description for the energy conversion that happens when solar panels are used to make electricity is C. Light energy to electrical energy.
Here's why:
Solar panels work by allowing particles of light, or photons, to knock electrons free from atoms, generating a flow of electricity. This process is known as the photovoltaic effect. Therefore, the energy conversion that is happening is from light energy (the energy from the photons) to electrical energy (the energy carried by the freed electrons).
