Understanding the Basics of Solar Panel Installation
A. Components of a solar panel system
A solar panel system consists of several components, including solar panels, inverters, mounting systems, and electrical wiring. Solar panels are made up of photovoltaic cells that convert sunlight into electricity. Inverters are responsible for converting the direct current (DC) electricity produced by the solar panels into alternating current (AC) electricity that can be used to power appliances and devices. Mounting systems are used to secure the solar panels to the roof or ground, while electrical wiring connects the solar panels to the inverter and the electrical grid.
B. Types of solar panel systems
There are two main types of solar panel systems: grid-tied and off-grid. Grid-tied systems are connected to the electrical grid and allow homeowners to use solar power when it is available and switch to grid power when needed. Off-grid systems, on the other hand, are not connected to the electrical grid and rely solely on solar power. These systems typically require battery storage to store excess energy for use during periods of low sunlight.
C. How solar panels work
Solar panels work by harnessing the energy from the sun and converting it into electricity. The photovoltaic cells in the solar panels contain layers of semiconducting materials, usually silicon, that absorb photons from sunlight. When the photons are absorbed, they knock electrons loose from their atoms, creating an electric current. This current is then captured by the wiring in the solar panels and sent to the inverter, where it is converted into usable electricity.
