Coming soon · a free sun map for your yard

Know your sun.
Grow your land.

That sunny spot by the fence? It probably gets four hours, not six. Sunsector maps every square foot of your yard — hour by hour, season by season — so you stop guessing and plant where things actually grow. We're putting the finishing touches on it now — add your email and we'll tell you the moment it's ready to try.

A real sun map

Every square foot of your yard, scored by direct sun hours — the hot corners, the shady beds, and everything between. This is what lands in your inbox when we launch.

Your sun map in three minutes

No sensors, no soil probes, no waiting for summer. Draw, drop, done.

1

Draw your yard

Type your address, trace your property line, and you're on a real satellite view of your actual lot.

2

Drop in what casts shade

Your house, the neighbor's fence, that big maple. Each one throws the same shadow it does in real life.

3

See your sun

A color map of direct sun hours across every square foot — the hot corners, the shady beds, and everything between.

It's not a guess. It's the sun.

Watch the day happen

See the sun cross your sky

Drag a slider and watch shadows sweep across your yard from sunrise to sunset. The spot that's golden at 9 a.m. might be in deep shade by three — now you'll see it before you dig.

Every day, a little more

Sunrise, sunset, and the light you're gaining

Open Sunsector and it greets you with today's sunrise and sunset for your spot — and exactly how many minutes of daylight you picked up since yesterday. Spring creeps in two minutes at a time.

The detail that saves plants

Morning sun or afternoon?

Three hours of gentle morning sun is a different world from three hours of blistering afternoon. Sunsector splits the two — so you can tuck wild columbine and hostas where they want it soft, and put the tomatoes where it's hot.

June isn't September

Compare your seasons side by side

Slide between two dates and watch the shade line move with the season. The bed that bakes in July may be shaded out by October. Plan for the whole year, not just today.

Light through the leaves

Turn the shadows on and off

Toggle the shade animation to watch how your trees and buildings paint the ground — dappled light under the canopy, hard shade behind the garage. It's your yard, lit the way it really is.

The whole season at a glance

Your growing-season sun average

Tell Sunsector where you are and it works out your growing season — first thaw to first frost for your location — then averages the sun across it. So you know the real daily light a bed gets all season, not just the number for one day.

Real math. No guesswork. No AI.

Sunsector uses the same solar equations that publish official sunrise and sunset tables — pointed at your exact coordinates and the real height of your trees and buildings.

Every number is calculated, not invented. And your data stays yours — we don't sell it.
