Plan for an amp hour / hour.. 24 amp hours / day. if you buy a
couple of 100 amp hour walmart marine batteries you'd have 200/24 or
about 9 days of run time without solar. I don't know what solar
planning you need in Jersey. DoE has some maps of the US for solar
planning - if it works out you only have 4 8 hour days around dec
21st to charge your batteries, you'd need to calculate feeding the
load - 1 amp continuous for 24 hours - which means 24 / 8 solar hours
= 3 amps during that 8 hours for the load, plus battery charge time
input. So, if you plan to charge the batteries to peak from zero in 3
days, you'd need 200 / (8 hours (charge day) * 3) or about 9 amps for
that. So a solar array might be 9 + 3 or 12 amps output @ 12 volts.
The Moto stuff will work fine @ 12 volts, even though they are spec'd
for higher. Finding a good 12 volt switch or router that suits you
and draws little current can be a struggle.
hope this helps. by the way, I'm in Califon for the next couple of days.

Anyone done battery / generator sites with one Canopy AP, one
Canopy SM and a router, like Mikrotik in between ?
This is in NJ, not too good an environment for solar I imagine,
although we'll be on a real high hill top (1250' elev) for this
area...
