Most households with only solar panel (PV) systems use around 25% of the energy they generate while systems with a solar battery use around 50 to 60%.

While a solar battery will give you more control over the clean energy you generate, you should also look at how you use power in your home when considering one.

A household with moderate energy usage that invests in solar panel (PV) and a mid-sized battery (around 10kW) can expect to save on average over $1,400 per year, and receive a return on investment over 10 years.
