There are three main types of solar power systems:
Grid-tied systems: The most popular solar system type; the home is connected to the grid so it can use electricity from the utility when the solar panels aren’t producing enough energy to power the home
Hybrid systems: Also called ‘solar-plus-storage systems’; the solar panels are paired with a solar battery to store energy for the home to use later on or during a power outage, and the home is also connected to the grid
Off-grid systems: There is no connection to the grid and the home runs entirely off of energy generated and stored on-site
