What does the microclimate analyzer actually show?
A 3D shadow map laid over your address. Pick any hour of any day of the year and it draws where the house, walls, trees and the neighbors' buildings put shade on your lot.
Why does afternoon shade matter so much in Phoenix?
July afternoons here are the limiting factor for most food plants. A spot with sun until noon and shade after is where tomatoes, herbs and young fruit trees survive their first summers. Full west sun is for the toughest plants only.
Are the A to F letters a grade?
No. They describe the type and timing of sunlight around a structure. A and F are both useful; they just suit different plants. The south-facing side gets the most year-round sun and the north-facing side is shadier, and the letters run from east to west along each.
Do I need an account?
No. Type your address on this page and the analyzer opens on your roof. With a free account the map is saved to your property, so the planting planner and any design review use the same sun and shade.
Is the shade map exact?
It is exact for the shapes it knows: buildings and terrain. Tree canopies and new walls may not be in the data yet, which is why the third pass is walking the yard.
