Off-grid PV systems have traditionally used rechargeable batteries to store excessive electricity. With grid-tied systems, excess electricity could be despatched towards the transmission grid, while standard grid electricity might be used to fulfill shortfalls. Net metering systems give home systems credit for any electricity they deliver to the grid. This is often dealt with by 'rolling back again' the meter whenever the home provides more electricity than it consumes.
