To fully understand the realm of solar energy, it's essential to familiarize yourself with its key vocabulary:

• Photovoltaic (PV) cells: Semiconductor devices that convert sunlight into electricity.
• Concentrated solar thermal (CST) systems: Use mirrors or lenses to concentrate sunlight to generate heat.
• Solar panel: An assembly of PV cells designed to produce electricity.
• Solar array: A group of connected solar panels.
• Inverter: A device that converts DC electricity produced by PV cells into AC electricity compatible with household and grid use.
• Battery: Stores excess solar energy for use at night or during grid outages.
• Solar tracker: A system that adjusts the position of solar panels to maximize sunlight exposure.
• Net metering: A billing arrangement that allows homeowners to sell excess solar energy back to the grid.
• Solar irradiance: The amount of sunlight that reaches a particular location.
