Understanding Solar Panel Basics
Before diving into the specifics of the Harbor Freight 100-watt solar panel kit, let’s first understand the fundamental principles of solar panels. Solar panels, also known as photovoltaic (PV) panels, convert sunlight into electrical energy through the photovoltaic effect. This process involves using semiconductor materials, typically silicon, to absorb sunlight and release electrons, generating an electric current.
Solar panels come in various sizes and wattages to meet different energy needs. A 100-watt solar panel is considered a small panel, suitable for powering small devices and appliances or charging batteries.
