Just made my solar panels adjustable and was trying to figure out what angles to use in the winter and here's a chart that helps you figure out the tilt angle for your panel. You'll note that major cities on opposite sides of the country are listed, showing an approximate latitude for them. Find your location on a parallel between these cities, then use the associated angle to set your tilt.
City Lat. Angle
Brownsville, TX-Key West, FL___25______________25
Corpus Christi, TX-Tampa, FL___28______________31
Austin, TX-St. Augustine, FL___30______________35
Tucson, AZ-Savannah, GA________32______________39
Los Angeles, CA-Wilmington, NC_34______________43
Las Vegas, NV-Raleigh,NC_______36______________47
San Francisco, CA-Richmond,VA__38______________51
Redding, CA-Philadelphia, PA___40______________55
Medford, OR-Providence, RI_____42______________59
Eugene, OR-Portland, ME________44______________63
Portland, OR-Duluth, MN________46______________66
Everett, WA-Grand Forks, MN____48______________68
Planning on wintering farther north than these latitudes? Skip the tilt chart, consult the yellow pages under the heading, "psychoanalysts."
