How this service works
Measures solar orientation index for exactly two European coordinates with one method and reports the signed difference and winner where meaningful.
Output
Returns the solar orientation index value for each of the two input European coordinates, along with the signed numerical difference between them (first minus second or clearly labeled), and identifies the winning location where the difference is meaningful.
Example use cases
Solar panel site selection
“I'm evaluating two land parcels for a solar installation — one in southern Spain at lat 37.39, lon -5.99 and another in central France at lat 46.23, lon 2.21. Which one has the better solar orientation index and what's the difference?”
Agricultural land solar suitability
“I want to know which of my two farm fields in Europe gets better sun based on terrain orientation: Field A is at lat 51.51, lon -0.13 in England, and Field B is at lat 48.21, lon 16.37 in Austria. Can you compare their solar orientation scores?”
Real estate investment comparison
“We're deciding between two properties for a passive solar home — one near Munich at lat 48.14, lon 11.58 and one near Lisbon at lat 38.72, lon -9.14. Which location has the higher solar orientation index?”
Technical details
Endpoint
POSThttps://landvergleich.halowerk.com/v1/compare-two-solar-orientationWhen to prefer
Use this endpoint when you need to compare solar orientation specifically for exactly two European locations and want a single definitive metric with a signed difference and winner. Prefer this over multi-site ranking endpoints when the comparison is binary and precision of the two-site delta is important. Best suited for solar siting, land valuation, agricultural planning, or real estate decisions within Europe.
Side effects
- Coordinates outside European coverage (latitude 34–72.5, longitude -31.5–40.5) will be rejected
- Fewer or more than exactly two location objects in the array returns a validation error
- Missing required latitude or longitude fields causes a schema validation failure
- Identical or very close coordinates may yield a near-zero difference with no clear winner
- Payment failure or insufficient USDC balance results in a 402 response
