Stake (sundial) shadows have nothing to do with trees or buildings in the area,
which is the usual problem when siting solar. It's either in the shade, or it
is not,
you don't need an algorithm to determine that. You only need one stake, or your
address, to determine sun angle. (I.e., your
A link would sure help here but basically you want to figure out how much
power that lamp consumes and how long per day you want it on. That will tell
you how much power, on average, you'll need to keep it running.Double that
number and you've got about the amount you'll need to generate on
This is a $49 Home Depot special lamp.

Just way oversize your solar panel and battery pack.
How big a light are you looking to run? A 35ah wheelchair battery will run an
LED for a long time. You don't have to mount the battery and solar panel right
next to each other and neither of those needs to be near the light...

Thanks for all the input. Turns out that all my candidate mounting points
were high shaded. I may have to move.

Simple, don't drive a stake in a shade area.. the sun obstruction will be
obvious.
The stakes with the shortest shade will have the most direct sun angle...
long shade means you are in a low sun angle, not good for absorbing UV to
make electric..
Think, sun dial... when the sun is at high noon...

Go to Home Depot or any hardware store.
Buy a bundle of 2 ft long grade stakes.
Drive a grade stake in each location you think you want to mount the solar
panel.
Starting at sunrise.
Every two hours, measure the shadow length of the grade stake, and the
angle.

Direct observation is a great way to do it. You do not, however, have to
sit in the yard the entire day. You should already have some idea

Q: I need a specific kind of wheeled chair thingy, where can I get one?
A: We sell all kinds of wheels and structural steel, you can weld up exactly
what you need.
Q:
Use a 12V solar panel big enough to run the VDO Quartz clock from
an MB instrument cluster. (W114 or newer.) No battery, clock runs
when there's sunlight, doesn't when not. There's your data logger.
Just remember to read it every 12 hours so you don't drop a stitch.
You might need to mask off
Get an old battery powered analog watch, take the battery out and power it
with a solar cell. Set it to high noon, put it at night, the next night it
will tell you how many hours and minutes of sun it got.

I think I will just sit in the yard all day and take notes with pen and
paper.

Get a photocell and hook it to an arduino with an SD card to log data and a
very simple program to write a photocell reading every say 5 min and it will do
that as long as it has power. Pull the card every few days, look at the data
and Bob’s yer unkie

Well, there will be considerable
I want to install a solar powered security lantern somewhere on the side of
the yard that receives enough sunlight to fully charge the batteries and
maximize the time the lantern is lit.
To that end I am looking for a measurement device I can leave outside in
various spots in the yard to find the
