Variables affectingsolar storage

Solar storage is potentially a great option for existing solar panel owners. The financial viability of the battery will depend on your individual circumstances, for example: the size and generation capacity of your current solar system, the amount of electricity you use and your usage habits during daylight hours.

The Australian population uses more electricity during the peak morning and evening periods. Depending on the season, your solar system is not likely to be producing energy during these periods. So you have to purchase it from the grid.

The economics behindsolar storage

At the heart of the solar storage equation is what happens with the excess solar energy you produce during daylight hours. For solar panel owners that do not have a storage solution, any excess power is fed straight back into the grid, where your retailer will pay you a financial credit per kWh. Then at night when you need to purchase power from the grid, your retailer will then sell it back to you at a higher rate; the greater the difference between these two rates the more viable buying a battery is. However, in recent years, higher feed-in tariffs means that adding a battery isn’t as attractive as it once was.

However, in recent years, the disparity between the buy back rate and the cost of electricity has remained stable, despite rising electricity costs; meaning that solar batteries are only economically viable in some cases.

The cost of solarbattery storage

The cost of solar storage has come down markedly in recent times, and the trend is set to continue. Technological and manufacturing developments like Tesla’s Powerwall battery are driving prices down and making solar battery storage more viable. Costs may vary significantly between suppliers.
