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?
