Whats the difference or advantage of solar concentrators and other leading forms of solar energy producing technologies?

Hines: Solar concentrators use CPV technology. By using lenses and/or mirrors, you can focus more sunlight onto a smaller area and dramatically reduce the amount of photovoltaic (PV) material that you need. PV is the most costly part of a solar power system, so if you can cut that by 90 percent, as Heliotube does, it makes a big difference in price. CPV also enables much higher efficiency — when you’re only using a small amount of PV material, you can afford the best — which means you can get a lot more power from the same area of rooftop, or wherever you are installing your system. More power from a given installation means more savings on your electric bill. If you think like a customer in terms of payback and ROI, this is critically important. There are a number of other exciting technologies coming to market, and some of these are also expected to be low cost, but unfortunately they don’t address the problem of providing enough electricity to power modern homes and businesses.
