Comment Tracking is better (Score 1) 410
It looks like he set the flat array at an angle of 45 degrees and that it was never moved. Every major solar farm uses active tracking of the sun to point each solar panel directly at the sun in a way that maximizes surface area. I'm pretty sure every collection technique that doesn't involve the electricity generating medium has already been thought and is either being used or has been ruled out.
One major problem I see with this design is that is very susceptible to wind damage. This is one of the biggest problems in sunny, dry areas. The wind picks up sand and dirt and eats away at the solar panels. Big flat panels tend to deflect the wind to a large degree. A tree-like design would have wind blow right through it and get chewed up quick fast. Cleaning the panels would also be a very hard and probably manual job. Large solar farms has this process fully automated.
