What Is Solar Panel?
A plain-English explanation of Solar Panel — what it means, how it works, and why it matters for your home energy.
Definition
A device that converts sunlight into electricity using photovoltaic cells
Solar Panel Explained
A solar panel (photovoltaic panel) is made of silicon cells that generate direct current (DC) electricity when photons from sunlight knock electrons loose. An inverter converts this DC electricity into alternating current (AC) for use in your home. Excess electricity can be exported to the grid via the Smart Export Guarantee (SEG).
How Solar Panel Works
- 1. Sunlight hits silicon photovoltaic cells in the panel
- 2. Photons knock electrons loose creating direct current (DC) electricity
- 3. An inverter converts DC to AC electricity your home can use
- 4. Excess power is exported to the grid earning SEG payments
