Re: [AFMUG] solar question
First figure out how many kWh all that consumes in 31 days... Then calculate what pvwatts says an off grid solar system of N size (example: 3kW) can produce in December and January.

Re: [AFMUG] solar question
My load estimate is also based on 6 watts per radio (which is the number I usually see thrown around), but I suspect the actual average would be closer to 4 watts, which is going to put it right in line with your 1.3-1.4 amp @24v estimate, which would put 20X the load at something more like 650 watts. A lot really depends on how easy the site is to access and how tight your budget is. On Tue, Jul 5, 2016 at 1:35 PM, Jesse DuPont <jesse.dup...@celeritycorp.net> wrote: > Agreed!

Agreed! My sizing was based on my willingness to take generator to the site if
there was no charging for 4.5 days (which I never had to do last winter, but
last winter seemed nicer than ones prior - I'm in Western SD). Chucks battery
sizing will at least double that run time and probably more (depending on
battery temp) and the additional panels will charge them more quickly after
extended run down.

You could probably get away with 500 watts of panels, like Jesse said, but if
you want to be sure it's never going to have problems, go with Chuck's numbers.

Ok what size solar panels are we talking about jesse is saying 2 x 250 watt

Re: [AFMUG] solar question
If you live in an area with no snow, no ice, lotsa sun, then 10X the load and a week of batts will barely suffice. If you have snow, ice, locations that are hard to get to, etc then 20X the load and two weeks of batts will take care of you. I have done this many times over on many mountain tops. I have also hired helicopters at 2000/hour to get to sites that did not have enough panel or battery. If you can drive to the site year around to top off a battery during periods of inclement weather, then you can cut back on the size of the battery. Telemetry is very important no matter what you do. You can keep an eye on things and know they are going to fail before they do. You can also remote start a small propane generator with telemetry too if you want to scrimp on panel. If money is tight, go with the larger battery and smaller panel. If money is squeaky tight, remote start generator and batts can be the whole system. Just start it once every 3 days and let it run for an hour.

50 watts=1000 watts of panel. $650 16.8 kWh of battery. $2500 + controller. $300 Two weeks of autonomous use, enough solar panel to not use batteries when overcast. Guaranteed to work.

Re: [AFMUG] solar question
With that equipment, you probably have about 1.3-1.4A of load at 24VDC. Using 2x250W, 24VDC panels and 4x100Ah batteries should get you through 4-4.5 days of heavy overcast. If you need more runtime, add another pair of 100Ah batteries. An MPPT controller will charge better as the panels reach full voltage during the day (PWM controllers are less expensive, but will limit charge efficiency). Where you are, I'd consider putting the batteries in the ground in some kind of an enclosure. This will keep them at least 35-40F in the dead of winter, giving you predictable run time when it's cold. I just make a 4' x 4' x 4' box with hinged lid made from treated lumber, dig a hole, put gravel on the bottom of it, throw in the box and back fill. Insulate the top 12" and the lid and they'll stay warmer. It's not elegant, but it works. There are much better solutions out there, I'm sure.
