Hello Mr Jim Jam 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?
BTW what really matters the most in choosing a solar panel is... A reputable supplier with a solid reputation. A fully tested and certified panel with a long warranty. Good year round performance. Competitive price. Watts per acre is not usually a major concern. We have lots of land. Land does not depreciate.
Dear Keefwivanef technology is not a walk in the park. CPV now not like PV have a matured industry chain. when new tech appears always need to face dissenting opinions. And dissenting opinions will promote the tech improve. Thanks.

Square's building is almost finished. Roof and walls are completed. Pouring the slab as I write. I'm in India and will post updated photos. They will shortly receive their first 50k shipment of receivers from Emcore.
Tell you what Mate. A lot of business is not even on the net. These guys have big orders. They have no need to look for customers. So you can stick that up your "ridiculously amateurish" ass and piss off.
