Greetings,
   I'm trying to make a decision as to which site to use for a communications 
system.  One site has very little in the way of protection or climate control 
(no blockhouse or vault) so it will require that a 'box' be obtained for the 
equipment and some sort of climate control/conditioning be included.  On the 
plus, the site is at a slightly higher altitude and has a bit better RF 
coverage.
The other site has a concrete blockhouse with a locking steel door and access 
control by means of a barbed wire chain-link gated fence, but it has no AC 
power and for that reason has been abandoned by other users.
The equipment I plan on installing requires no more than 15 amps total at 
12vDC, and then add a few more for cooling fans (no refrigeration) for a 
grand total of probably around 20-25 amps, now what would be the best power 
storage and recharging system for the non-AC supplied site (on a small 
budget) ?  The blockhouse is out in the open, so there is nothing around to 
shade the solar cells.  And operation needs to be 24hrs/7days, at a 50% or 
higher duty cycle.
A fueled generator is not a consideration, as the site is not accessable at 
all times of the year.
'Til next time,
     Bruce
