What Is the Cheaper Home Batteries Program?

The Cheaper Home Batteries Program is a federal solar battery rebate that cuts the cost of installing a home battery energy storage system. Benefits include:

- Reduce upfront costs: For example, save around $4,000 on an 11.5 kWh battery previously priced at about $13,000.

- Lower electricity bills: Households may save $700–$1,600 per year, depending on usage and tariffs.

- Boost energy resilience: Store excess solar power to use during peak periods or outages.

**Figures are estimates and will vary by system size and location.**

How the Rebate Is Calculated

Rebates are based on Small-scale Technology Certificates (STCs) . The formula is:

Rebate = Usable kWh × STC factor × STC price

Installation Year STCs per kWh Estimated Rebate per kWh
2025 ~9.3 ~$372
2026 ~7.8 ~$312
2027 ~6.2 ~$248
2028 ~4.7 ~$188
2029 ~3.1 ~$124
2030 ~1.6 ~$64

*STC prices are market-based and change over time.
