## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability solarpulse-solar-energy-estimator-049c82fc
```

Example prompt: Can you estimate the solar energy potential and savings for my home at 452 Maple Drive, Austin, TX — I use about 1200 kWh per month and my bill is around $180/month, and I'm thinking of a 7 kW system with a 25-degree roof tilt?

## When to prefer this

Use SolarPulse when you need a quick, location-specific solar energy and savings estimate for a US residential address or coordinate pair, especially when you have household consumption or billing data to improve accuracy. Prefer this over generic solar calculators when you want API-level granularity with optional inputs like system size, roof tilt, and monthly usage.

## Known failure modes

- Missing required location — must provide either address or lat/lon pair
- Invalid or non-US address returns an error or no results
- Lat/lon values out of valid range cause a bad request error
- System size outside 1-25 kW range rejected
- Monthly kWh outside 50-10000 range rejected
- Monthly bill outside $10-3000 range rejected
- Roof tilt outside 0-60 degrees rejected

## How this service works

Rooftop solar estimate for a US address: system size, monthly and annual production (NASA POWER), utility rate (EIA-861 2024), installed cost (LBNL Tracking the Sun), payback, 25-year savings and the 2026 federal credit status.

## Output

Returns a solar energy estimate for the given location including projected energy production, recommended system sizing, and estimated savings based on household usage and bill inputs.
