What is the battery storage price index?

The aim of the Battery Storage Price Index is to assist homeowners assess whether batteries are worth their while without having to engage with battery vendors before they are ready.

How does battery capacity affect cost per kWh?

An important trend to observe is that as the battery capacity increase, the cost per kWh decreases. This reflects the fact that many of the installation costs are fixed (regardless of what size battery is going in).

How much does a battery cost?

Pricing typically starts around $1,500 per usable kWh, with larger systems bringing that cost down significantly. Here’s how different battery sizes typically stack up: 5 kWh battery: A good entry-level option for smaller homes or tighter budgets.
