Multi-location simulation: Salt Lake City + LA + Denver

[mokahlo]

Goal

Validate the Wattplot design against multiple US states to support plug-and-play solar market entry (Utah SB 190, California AB 1076, Colorado HB22-1015).

Scope

• Add lat/lon presets for SLC, LA, Denver, Portland, Austin, Miami
• Run sun simulator for each location
• Compare annual kWh, DLI, tomato yield across locations
• Document wind speed + exposure differences and how they affect the design
• Recommend the best Wattplot variants per region (size, soil depth, panel orientation)

Reference

• analysis/sun_simulator.py — already location-aware, just needs more presets
• analysis/wind_load.py — uses LOCATION dict from wattplot_params.py

Done when

A 'where Wattplot works best' document published, with simulation results for 5+ US cities.
