- These presets are planning estimates. Live weather, shade, tilt, smoke, snow, heat, and panel direction can change the result.
- For site-specific solar resource data, run the same location in PVWatts and replace the preset with documented monthly values.
Planning Presets, Not Weather
This planner uses conservative monthly region presets. A future version can connect an authoritative solar resource API, but even then the result should stay a planning estimate.
Season
Winter and summer solar estimates can differ by several hours of equivalent full sun per day.
Station limit
A station cannot accept more solar input than its charge controller allows, even with a larger panel array.
