Hi Todd,

The sun moves, not the array, take advantadge of that fact.

Tilt the array toward the south to tune the array to winter maybe even 
vertical on a south wall.
Plant a deciduous shade tree, morning glory, grape etc.
Put up a louvered aluminum awning, tuned for sun in winter, shade in 
summer.

Use my Thermal Calc excel spreadsheet 
http://www.dcn.davis.ca.us/go/deant/ThermalCalc.xlt to model changes 
before you get on the roof. Thermal Calc hasSolar Pathfinder shading, 
azimuth and tilt functions, it includes NOAA data for Redding.
