How this service works
Measures solar orientation index for two to ten named European sites and ranks the observed values with ties preserved.
Output
Returns each named site with its computed solar orientation index value and an ordinal rank (1 = best solar orientation), with ties preserved so equal-scoring sites share the same rank position.
Example use cases
Solar farm site shortlisting
“I'm evaluating five candidate plots in southern Europe for a solar farm — can you rank them by solar orientation index? The sites are: Valencia (39.47°N, 0.38°W), Seville (37.39°N, 5.99°W), Palermo (38.12°N, 13.36°E), Marseille (43.30°N, 5.37°E), and Naples (40.85°N, 14.27°E).”
Agricultural land solar suitability ranking
“We're choosing between seven parcels in Germany and France for a solar-assisted greenhouse project — rank them by solar orientation score so we know which face is most favorable. Here are the coordinates: Berlin (52.52°N, 13.40°E), Munich (48.14°N, 11.58°E), Hamburg (53.55°N, 10.00°E), Lyon (45.75°N, 4.83°E), Bordeaux (44.84°N, 0.58°W), Stuttgart (48.78°N, 9.18°E), Frankfurt (50.11°N, 8.68°E).”
Real estate development solar ranking
“I have three potential development sites in Portugal and Spain and need to know which has the best solar orientation — can you rank Faro (37.02°N, 7.93°W), Malaga (36.72°N, 4.42°W), and Alicante (38.35°N, 0.48°W) for me?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/rank-sites-solar-orientationWhen to prefer
Choose this endpoint when you need to compare solar orientation across multiple (2–10) European sites simultaneously and require a ranked output rather than a pairwise signed difference. It is ideal for multi-site selection workflows such as solar farm siting, agricultural planning, or real estate due diligence where knowing relative rank across all candidates matters. For exactly two sites where only the signed difference is needed, a sibling pairwise endpoint may be more appropriate.
Side effects
- Fewer than 2 or more than 10 locations provided — validation error
- Coordinates fall outside European coverage bounds (lat 34–72.5, lon −31.5–40.5) — out-of-coverage error
- Missing required latitude or longitude for a site — schema validation error
- Site name exceeds 60 characters — validation error
- Network timeout or upstream computation failure — 5xx error
