The Federal Battery Rebate Decreases in 2026!

STC rebates are set to drop by 10% from 2025 to 2026, as the STC factor falls from 9.3 to 8.4 per kWh. This means less rebate is available for new battery installs.

For a typical 27 kWh battery, that’s nearly $1,000 less, around a $960 drop in STC value compared to 2025.

When you factor in solar STC rebates, which are also falling by nearly $400 for the average system, a full solar + battery setup could cost almost $1,400 more in 2026.

1KOMMA5° Energy Storage

Achieve Energy Independence

Six Reasons why Solar Battery Storage matters

1. Energy cost savings

By storing excess energy, you can use it when energy prices are higher, which helps to lower your energy bills and increase your cost savings.

2. Enhanced Energy Independence

An energy storage unit allows you to store excess solar energy for use during times when the sun is not shining. This helps to reduce the amount of energy that you need to purchase from the grid and increases the overall efficiency of your solar system.

3. Blackout Protection

With the right solar inverter installed, your battery solution could be used to keep key elements of your home up and running during planned/unplanned power outages.

4. Increased Solar Panel Performance

Store excess solar power to use at night and By storing excess energy, you can optimize the performance of your solar panels, increasing their overall efficiency and helping to lower your energy costs. 100% self-sufficient for most of the year.

5. Virtual Power Plant (VPP) access

Once you're Battery Storage is installed, you become eligible for Virtual Power Plant (VPP) energy plans, which allow you to sell excess stored power back to the grid as needed.

6. Increased Property Value

Installing an energy storage unit can increase the value of your property and make it more appealing to potential buyers.
