- People comparing solar potential across locations
- Worth noticing
- The estimate includes cloud cover, haze and air temperature, but explicitly excludes snow accumulation on panels.
Field notes
The method section describes a fixed installation at its best tilt and distinguishes the modeled long-term average from any single year’s weather. It says cloud cover, haze and air temperature are included, while snow on the panels is not. The page also warns that roof angle, direction and shading can change real-world output; the extracted interface reports a renderer problem and shows several values still loading.
