I am trying to decide if is better to go with a flat panel mounted on a tracker, a CPV unit on a tracker, or a simple fixed array of flat panels.
Looking at the data on this site it appears there is no great advantage to using trackers.
CPV claims that it can deliver more power to the acre.
The test results do not confirm that.
A tracking array of necessity requires adequate spacing between units resulting in less collection area per acre.
Triple J cells are claimed to be twice as efficient as silicon or thin film
All CPV designs use circular mirrors or lenses.
A circular lens/mirror within a square matrix wastes over 20% of the collection area.
Further losses occur in the optics.
Even though the temperature coefficient of the 3J cells is better than silicon, the cells run VERY hot.
Complex tracker consumes power.
Even a light cloud passing over causes huge power fluctuations.
Would somebody kindly present a rational argument in favour of CPV.
I am growing weary of the mantra "NEED MORE TIME,NEED MORE MUNNY"
BILLIONS of dollars has been given to these CPV solar companies and what do we get?
Solar Systems of Australia!!
Yeah....Right!!!
