Can you specify the usage(in Watts) of these equipment you mentioned and
voltage ?
A 50W solar panel looks Ok, but you need to calculate the usage in Amps
so you can find out how long the battery of that capacity can run
without sun and you need the Watts and Voltage for that.

How do you calculate ideal battery for solar nodes? I know that it
depends on how much routers there are planned. But for example let's
use solar node that has one nanostation nanobridge for unplink and
picostation for AP.
I guess that 50W solar panel should be enough, right? But how big
should the battery be?
Is 7Ah enough?
At my company we use 92Ah batteries for powering ADSL DSLAMs, and are
replacing then now with new ones. Using a too big battery is also not
advised because then you need much bigger solar panels because lead
battery also looses lots of power due it's internal resistance.
So 92Ah is much too big, but is 7Ah too small? Does anybody have
experience with batteries and solar power?
