On-grid photovoltaic systems can mitigate anywhere from a small percentage to all of your electricity requirements. A typical system consists of PV modules placed on or near the home, a small inverter to sync with the electric grid, and breaker backfeeding solar electricity into your home and electric grid!
An on-grid PV system is truly like operating your own power plant. When the grid is down your power plant will also be down. Battery backup is available so your PV system can operate in the eventuality of grid outage. In areas prone to grid outage, battery backup systems are the perfect means to a self-sufficient home. However, batteries are an expensive option and are not generally recommended.
