Narada battery 12V100AH and iron lithium battery

Solar cells provide energy storage for solar, wind or other renewable energy systems. A solar cell is simply a deep cycle battery - a battery designed to store and distribute the long, repeated and deep charge/discharge cycles required to store and distribute energy from intermittent renewable energy sources such as solar panels. Therefore, car batteries cannot be used as solar cells. Grid-tied systems do not require batteries unless you want to maintain power during utility grid outages. But for off-grid systems, deep-cycle solar cells are essential and may provide 100 percent of the power. This makes correct sizing of solar arrays one of the most important steps in off-grid system design.
