Solar Production Forecast for a Panel Setup (Forecast.Solar)

forecastsolar/estimate

Forecast of solar electricity production for a panel setup at a place: power in watts and energy in watt-hours at each point of today and tomorrow (hourly, from sunrise to sunset), plus the daily total. Give latitude, longitude, tilt, azimuth and installed kWp. Forecast.Solar estimates computed from weather data, refreshed at most every 15 minutes; estimates, not measurements. Forecast.Solar data, passed through unmodified and served by Eden Engine; not an official Forecast.Solar product.

// 1. search: find the tool
omnial_search({ query: "what you need" })

// 2. inspect: price and input schema
omnial_inspect({ tool: "forecastsolar/estimate" })

// 3. learn: read the usage guide at runtime
omnial_learn({ tool: "forecastsolar/estimate" })

// 4. run: price the exact call first, then run it
omnial_execute({ tool: "forecastsolar/estimate", input: { /* see input_schema */ }, dry_run: true })
omnial_execute({ tool: "forecastsolar/estimate", input: { /* ... */ } })

// 5. settle: the call is charged when it finishes, nothing to do
