Resolve a UK postcode, place name, or "lat, lon" to coordinates.
GET /api/v1/resolve?q=IV51%209EX
→ { "lat": 57.51, "lon": -6.29, "label": "…", "via": "postcode" }
List the turbine models available for prediction.
GET /api/v1/turbines → { "turbines": ["LE300", "LEV50", …] }
Estimate annual generation from wind, and optionally solar.
| Param | Meaning |
|---|---|
lat, lon | required — decimal degrees |
turbine | model name from /turbines (e.g. LE300) |
num_turbines | count (default 1; 0 = solar only) |
hub_height_m | mast height, metres (max 10) |
panel_kw, tilt, azimuth | optional solar array |
product | optional: "Solar Trailer" or "Power Box 2" |
GET /api/v1/predict?lat=57.51&lon=-6.29&turbine=LE300&num_turbines=2
→ { "wind": { "annual_p50_kwh": …, "annual_p90_kwh": …, "mean_wind_ms": … }, … }
p50 is the typical year; p90 is conservative (exceeded in ~90% of years).
Pick the best-fit turbine for a site, optionally sized to a load (watts).
GET /api/v1/recommend?lat=57.51&lon=-6.29&load_value=400&load_basis=continuous_w
→ { "recommended": "LE300", "candidates": [ … ] }
