Why new ETC (Evacuated Tube Collector) Technology is better than the old FPC (Flat Plate Collector) Technology?
The ETC technology is almost a decade old and thus not so new! This technology, though much superior and suitable than FPC technology, could not take-off being more expensive than FPC technology. If you see the comparison chart below, it will be obvious that the only advantage FPC ever had over ETC was lesser price. But NOWADAYS, with recent worldwide advances in mass production techniques of evacuated tubes, ETC based systems are more cost effective than their FPC counterparts. In other words, FPC systems are as obsolete as typewriters in the computer age. Please see the comparison between the two technologies Click Here for more details.
