>We have installed  Sayno modules  due westerly direction and have had very 
>little reduction of output. The Sayno 190D if your array is tilt up and 
>the roof is somewhat reflective, charges from both sides & might be an 
>interesting option for your client. Contact me off list for additional info.

>I have a customer that has asked me to design/price a 22kw system for a
>hotel.  The back of the roof is about 26 degrees tilt but facing 120
>degrees, 60 degrees off of due south.  I ran the numbers on PV Watts and
>it showed only a 7.6% loss of power.
>
>Can anyone comment from experience on an installation 60 degrees to the
>east of south?  I don't want to make a poor recommendation.  Because of
>the site layout there is very little possibility of a canopy/parking
>type installation which is what I would like to do.
>the roof is ideal otherwise.
