As you can see from this info-graphic above, batteries fit quite seamlessly into any solar system.
Normally, on a system without a battery, excess energy that is generated is sent to the grid during daylight hours. Then at night, when no energy is being produced, energy is drawn from the grid in order to power your appliances/home. This is a very straightforward and simple process, the only problem occurs when energy you draw from the grid is more than energy you send, meaning you get less return on investment through feed-in tariffs. If your household consumes large amounts of electricity, this is where a solar battery may be a smart investment choice.
On a solar system with a battery installed, the process is slightly different. Excess energy you produce during the day, is sent to your solar battery first until it is at full capacity. After your battery is fully charged, any excess energy produced is then sent to the grid. At night, energy is first drawn from the solar battery until it is completely empty, then if power is still required, it will be drawn from the grid. The potential positive impact a battery has on your solar system is that if you are only producing enough energy to rely on your solar battery, your energy bill for each quarter will be $0 (you read that right). Not to mention if you can operate purely on your solar battery, whilst still sending excess energy to the grid, your solar system will in fact make you money! Talk about a smart investment.
So now that we’ve discussed how it works, let’s talk about why you should seriously consider installing a solar battery.
