how does solar energy work??

We convert sunlight into electricity using
machines called solar photovoltaic cells.

These machines are thin,metallic plates
that transform the heat from the sun into
electricity that we can use to power our homes.

These machines come in many shapes and sizes.
They are found in calculators,space satellites,
emergency roadside telephones and even billboards.
