You don’t necessarily need batteries for your solar energy system.
Depending on your goals for this project, we will help you evaluate the efficacy of a battery backup system. Do you want to have power when the utility grid goes out? Is your goal lowering your monthly bills? A backup battery bank can add as much as 25% in cost to a residential solar PV system. Also, it may yield about 7–10% less energy if it’s battery-tied than its grid-tied counterpart.
Solar energy battery backup systems can be connected to the utility grid so you always have access to a power source. Though you will remain tethered to your local utilities’ grid, you will not have to worry about not generating enough power. You also gain the advantage of offsetting rising utility costs.
Grid-tied photovoltaic systems generate energy, which is either consumed instantly or the excess is credited to you by your utility, reducing your utility bills. Battery backup grid tied systems generate energy, offsetting electric bills and selling excess to utility, as well as maintain batteries in case of outages. If the grid goes down, these systems are designed to support a designated “critical load” of appliances the system’s owner must keep running.
