The sun’s rays shine down onto panels of PV cells, otherwise known as solar panels, which begins the energy harnessing process:
- Particles of sunlight known as photons hit PV panels and are absorbed by the silicon found within the panels.
- Photons knock electrons loose from their atoms causing an electrical potential difference.
- Current flows through the panels to cancel the potential charge difference, which in turn is captured as direct current (DC) The semi-conductive properties of the silicon allow the current to flow in one direction only.
- The electricity is harnessed as DC electricity and converted by an inverter into alternating current (AC) electricity and fed into the power grid for local consumption.
