How much do solar batteries cost?

How much do batteries cost infographic

The cost of solar batteries has been decreasing for a few years now, fuelled by the rise in electric vehicles, government rebates and increased demand driving competition in the industry.

But like solar panels, a battery is still a big investment and different batteries come with different price tags.

As a rough guide (as at January 2020) a 5kWh battery system fully installed would likely cost around $7000 – $12,000, a 10kWh battery system could cost $10,000 – $17,000 and a 15kWh battery system might cost $14,000-$25,000.

These are pretty broad ranges, so what are the factors that influence the cost of a solar battery?

  • The quality of the battery – like solar panels, not all batteries are made equal. Don’t trade quality for low cost, look for a battery that’s backed up by a good warranty and a reputable manufacturer.
  • The size of the battery – batteries range in capacity from as low as 2kWh right up to 15kWh plus. The more you get, the more you pay (although the cost per kWh tends to go down as size increases.)
  • The type of battery – batteries come in either low voltage or high voltage models, with high voltage generally more expensive.
  • The battery chemistry – most home batteries are lithium-ion, but there are also lead acid batteries, salt-water batteries and flow batteries, all of which cost different amounts.
  • Grid connected vs off-grid storage systems – off-grid battery systems are more complex and extensive than grid-connected systems, so they generally cost more.
  • Brand – like many consumer goods, some brands are more expensive than others. Sometimes, you pay more for the shiny logo.
  • Variations in installation and sales prices – just like Harvey Norman may have a different price on an air conditioner to The Good Guys, different retailers and installers offer different prices.
