SLAs are actually made for deep cycle use. Depth of discharge affects lifespan to a degree however.?

Many quote the maximum output at solar noon, midsummer, clear sky and the panel angled at the sun.
Obviously this can be even x10 the actual output even on a good day in the other half of the year unless you live closer to or in the tropics.
Three 100W panels, special charging electronics and a suitable battery system. Car batteries are best value but heavy. Li batteries may take deep cycles well. NiMH less tricky, can be similar volume capacity to Li, but much heavier and expensive other than AA size. Lead Acid gel don't like repeated deep discharge.
Likely for a rig the duty cycle is 1:5 unless in a pile-up/contest.·
