An electric car battery usually holds about 69.5 kilowatt hours (kWh) of energy. This can supply back-up power to an average U.S. household for around two days. Larger electric vehicles, like buses, have even greater energy capacity, allowing for a longer power supply during outages.
Integrating solar panels can enhance this system. Solar panels convert sunlight into electrical energy, charging both car batteries and house batteries during the day. A well-designed setup includes solar panels, car batteries, and inverters. This combination facilitates energy backup during power outages and reduces reliance on the grid.
Importantly, understanding the energy needs of your home is crucial. It helps in selecting the right battery capacity and solar panel size. For those considering this energy solution, knowing how to size the system is key to ensuring efficiency and reliability.
In the next section, we will dive deeper into the specifics of battery capacity and energy management, examining how to optimize your home energy backup system effectively.
