Do I need a solar battery?
Most Australian homes are not occupied during the day and therefore use more energy in the evening. The biggest issue that solar homeowners have faced in recent years is the frustration of generating solar energy during the day, and then having to buy the same energy back from the grid in the evening at a considerably higher rate.
A battery stores the excess energy that your system generates while the sun is shining, ready to use at night. This means that your solar can power your home during the day and your battery can power your home in the evening, dramatically reducing your dependence on the grid.
