How does solar power generate electricity
.
A solar thermal system generates electricity indirectly by capturing the heat of the sun to produce steam, which runs a turbine that produces electricity. A solar photovoltaic system produces electricity directly.
When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell.
Instead of turning sunlight directly into electricity, concentrating solar turns it into heat. Mirrors direct sunlight to a place—often a central “power tower”—where the concentrated heat boils a fluid. This boiling.
