Frequently Asked Questions

Do I qualify for a battery rebate?

Eligibility depends on your state, property type, and whether you have existing solar. Most homeowners with solar panels installed qualify, but there are income and property requirements in some programs. Our calculator checks your specific situation.

Are there income or property requirements?

Some state rebate programs have household income caps or require owner-occupancy. Victorian Solar Homes program, for example, has specific criteria. We'll flag any requirements that apply to you during the calculation.

Can I add a battery to my existing solar system?

Yes, in most cases. You'll need a compatible inverter or may need to upgrade to a hybrid inverter. Our calculator factors in your existing setup to give you an accurate estimate.

What affects the battery rebate amount?

Battery capacity (kWh), your state's current rebate rates, installation timing, and any stacking with federal incentives all play a role. Rebate amounts can change quarterly, so timing matters.

How long does battery installation take?

Typical installations take 4-8 weeks from signing to completion, including grid approval. Starting early gives you time to compare quotes properly and avoid being rushed into a decision.

Will you call me after I calculate?

Not unless you ask us to. The calculator doesn't collect your phone number. We only get in touch if you choose to find out what you're eligible for.
