[RE-wrenches] SE or SW

[Jesse Dahl]

Hello,

I was asked to look at a site today for a homeowner looking for a grid-tie with battery-back up. They are Doomsday Preppers for lack of a better term and want certain loads if and when the grid goes down for good. Aside from parts selection, they have two roof lines, one facing SE one facing SW. the SW is very low slope and is only accessible with a ladder and climbing on the roof, the other is SE, much steeper slope and accessible from the ground or deck.  I mention the access because of snow removal. We had lots of snow last year and I spent lots of time on my roof removing 8" snow falls.  Both have good solar access.  

I'm inclined to chose the SE roof line, but I am interested in arguments for the SW. 

Thanks!
