I was gonna say...
EPMP rocks on the power side.

Runs at 70 watts and it powers X3 AFXHDs, AC BH, AC Sector AP,
Solar is much less of a pain with UBNT cambium just sucks power so
you cambium guys have fun with that..

But your relay site is drawing what? 50 watts maybe.
Big difference between 50 and 250 when it is a constant load.

Up in the NC Foot Hills x3 220 Watt Panels x4 Golf Cart
Batteries keep Relay sites powered up nicely
the pricey part is the charge controller
Golf Cart batteries save you a lot in cost, but you will need
to keep an eye on the water level inside the batteries

We do about half the solar panels as Chuck, and we only
really need 10 days on the batteries. We have sometimes
done less on both of those and depending on the exact
location.
We are on the 37° parallel, and get no snow, and no really
hot weather, so we are in a fairly ideal solar
environment. I'm not sure exactly where you need this, but
you must be somewhere around the 28° parallel? You should
get a lot more sun, but you probably also get a lot of
cloud activity. Your typically higher temperatures will
derate your solar panels as their output decreases with heat.
You're burning 3600 watt-hours per day. That's a tall
order for a customer. I'm guessing this is a lot more than
just internet access?

Is this Florida?
In Utah, off grid, snow on the panels, worst case. No
sun for two weeks this is what I have used that has been
field proven.
20X load worth of panels
2 weeks of autonomy worth of batts.
I would say if you went 200 watts * 20 is 4000 watts of
panel.
So $2K for the panels.
200*24*14=67 kWh of batt * 10 cents = $6.7K for batts
You can get batts for as low as 6 cents per watt hour. I
used 20 cents there.
Batts may be as low as half that. Even less if you don’t
have to worry about snow etc.
So $10K in Utah.
In Florida you do not need 2 weeks. What is the longest
interval of solid overcast?
You also have longer days in the winter.
Bill Prince has some figures for no snow areas.

We have not done solar systems before, but am looking
at it for a customer.
Need 150watt sustained, so figure about 250 to cover
ourselves.
Looks like we get about 5.5hours per day of “peak sun”.
Any rough idea on how much it would cost for a system
to do this?
