How much sun does this site get?

Solar resource comes back as irradiance and modeled yield for an array with the tilt and azimuth you supply, from the European Commission’s model, alongside long run temperature, wind, and humidity from the NASA record. Both are modeled from satellite and reanalysis data rather than measured on the ground. Terrain and tree shading, soiling, and the equipment actually installed are what separate a model from production, and none of the three are in the model.

A point, modeled: hourly to annual irradiance and yield, plus long run climate normals.

Where this answer comes from.

Each of these has its own page naming the office that publishes it, how often it updates, and what it cannot answer. Rebuilt from the ParcelOps source directory on September 9, 2026.

Would answer this, not connected yet.

These sit in the same part of the ParcelOps directory and are not live, so they add nothing to the answer above today. They are named because a page that hides the unfinished half of itself is the thing this whole family is arguing against: FCC Broadband Availability.

Where this stops.

The part a search result will not tell you, and the part worth reading before this answer goes into a decision.

  • Near shading from trees, terrain, and adjacent buildings is the single largest source of error at the site scale, and the model does not see it.
  • Climate normals describe a long run average. They do not describe next year, and a single unusual year sits well outside them.

The lanes this question belongs to.

A lane page lists every source that kind of work reads, not only the ones behind this question, and states where the whole lane stops.
