How this service works
Solar irradiance + PV-yield forecast for any coordinate (free/keyless, global). Returns a daily 1-16 day forecast: GHI (kWh/m²), peak sun hours, sunshine hours, and estimated yield per kWp of panels (at a 0.75 performance ratio). For rooftop-solar planning, agrivoltaics, and EV-charge scheduling. Complements energy.solar-resource (NREL long-run averages, US).
Output
A daily array of up to 16 days of solar data for the given coordinate, including GHI (kWh/m²), peak sun hours, sunshine hours, and estimated PV yield per kWp of installed panels (at 0.75 performance ratio)
Example use cases
Example prompt
“Can you give me a 7-day solar irradiance and estimated PV yield forecast for latitude 34.05, longitude -118.25 — I want to know peak sun hours and how many kWh per kWp I can expect each day?”
Technical details
Endpoint
GEThttps://2s.io/api/energy/solar-forecast?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need short-term (1–16 day) daily solar forecasts for any global location, especially for rooftop solar yield estimation, agrivoltaic planning, or EV charge scheduling. Prefer over NREL energy.solar-resource when you need forward-looking forecasts (not long-run historical averages) and when the location is outside the US or you need near-term operational planning data.
Side effects
- Missing required latitude or longitude returns a 400 error
- Latitude outside -90 to 90 or longitude outside -180 to 180 returns validation error
- Days parameter exceeding 16 or below 1 returns a schema validation error
- Payment failure (x402) if USDC balance insufficient
- Upstream forecast model unavailable may return 503 or empty data
- Coordinates over ocean or polar regions may have reduced data quality
