Sooo Wrong

Tenley and I were driving to a site assessment when we went by a school zone. After getting past the first sign and towards the end of the zone, I realized that the PV modules where pointing towards each other. We were on a north-south highway, so one of the modules was bass ackwards.
If you look to the left in the distance you'll see the correct one facing roughly southwest. If you look to the right side you will see the pv module looking northeast. Only a summer sunrise will barely light it's face and in the winter, not a chance. This module will only gather a small fraction of the solar energy from back scatter in the atmosphere. I don't know if this is a new installation and the shortcoming not yet realized or it has enough reserve to keep functioning during the school year.
If you study the sign on the right you'll see that the pole is not tall enough to turn the module around. There was also some attempt to force-twist the frame further east. Who ever installed the signs went ahead with the short poles and hoped for the best, it was time to go home for dinner. It looks to me like the frame could be swiveled much further east to acquire more gain. The correct answer is to put in a pole about 3 or 4 feet taller and swing it around due south without blocking the signal or sign.
Best practice in solar installations is to be within 20 degrees either side of south. In a pinch up to 30 degrees off is acceptable with only about 4% loss of energy harvest depending on module tilt.
Solar installations are just starting to become popular so there are not many experts out there. But in a situation like this it ought to be a no-brainer....
