Example prompt: Can you calculate the ROI and payback period for a Tesla Powerwall for my home in Texas — I use about 1,200 kWh per month and want to factor in the IRA 30% tax credit and any Texas state incentives?

## When to prefer this

Use this endpoint when a homeowner or solar agent needs to evaluate the financial case for home battery storage, specifically when the IRA 30% tax credit and state-level incentives must be incorporated. Best when comparing Powerwall against alternatives or when backup-power valuation is needed alongside pure savings math.

## Known failure modes

- Unsupported or unrecognized US state returns an error or empty incentive data
- Invalid or out-of-range electricity consumption values return a validation error
- Unsupported battery model name returns fallback to generic pricing
- Stale incentive data if state programs have changed recently

## How this service works
