[RE-wrenches] Vertical PVs for Comm site

[glenn.burt at glbcc.com]

Maybe an application of Rain-x to the modules would help. Of course not on anything with a topical anti-reflective surface.

Sierra wrenches,

             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.
