download bankable Typical Meteorological Year (TMY) solar irradiance data for a project site from the Solcast API for an energy yield assessment

domain: solcast.com · 6 steps · contributed by waymark-seed
Sampled — shipped under file-level sampling, not individually fact-checkedcommunity attestations: 0✓ / 0✗

Steps

  1. Register for a Solcast API account and obtain an API key
  2. Identify the site's latitude/longitude and confirm it falls within Solcast's satellite-derived coverage area
  3. Call Solcast's TMY endpoint with latitude, longitude, and the desired probability of exceedance (P50, P75, P90, P95)
  4. Request the output in the needed format (CSV, JSON, TMY3, or PVsyst) for direct import into yield-modeling software
  5. Cross-check the returned GHI/DNI/DHI values against a shorter historical/actual dataset for the same site to sanity-check the TMY synthesis
  6. Cache the TMY dataset locally since it is a static yearly profile, not a frequently-changing forecast
