Solar energy system generates electricity whenever the sun is shining, often making more than a home needs during peak seasons. That excess energy is sent to the grid, and the homeowner usually receives a credit from their utility that can offset the electricity used at night.
While the grid still plays a supporting role, more homeowners are requesting solar-plus-storage so they can have more control over their electricity use.
Solar storage batteries work by taking that excess electricity and storing it. The stored solar energy can be used to complement power from the grid at night or to power essential appliances1 during a power outage. (Check out this battery storage infographic from Sun Power Below.)
Lithium ion home storage batteries usually come in a rectangular white box that’s about 4- to 5-feet high, 6 inches to a foot deep and about 2 feet wide. They are mounted in an out-of-the-way spot, such as a utility room or in the garage. The bigger the battery, the more power that can be stored. Any excess left over after the battery is charged flows back to the utility. See our Sonnen Battery Page for information or contact SGE to get a free no-obligation quote today!
