My 30 years of installation has never included comm sites
on mountain tops but I took the job.....
I am proposing mounting PVs vertically towards the top of the south wall
of a 2 story block building to avoid snow build-up. I assume a
pole-mount would be next in line if we needed more sq ft of PV.
However, even if vertical, will Sierra snow (its a special breed) still
wind-pack on, stay for weeks, days, not at all? This site is on the
Pacific crest at 7,000 ft.
And then due to potential temps down to -30F, I assume a
WELL insulated battery box (maybe even back-up heat?). It seems the best
choice would be to use AGM/VRLA/Gel? Part my reason for looking for
help is my customer's loads will only be 12 volt and wants to avoid the
cost of an inverter. This seems a little risky not to have an
inverter/charger for back-up. Appreciate the advice.
