CPV Outlook 2012: The Only Way to Go is Up

Like the small but scrappy fighter in the ring, the North American CPV has a long way to go to compete with the big boys. Even so, company executives appear hopeful about the future.

With great research and advances, concentrating photovoltaic (CPV) will be future energy option.

Hi:

Concentrating solar anything is, as always so far, limited to clear sky country. Until someone figures out a way to concentrate diffuse radiation, that will relegate CS to clear sky areas of the world. There is no point from an economic or engineering perspective to take on a solution that involves the complete overhead of tracking for a result that is the same or worse as non concentrating solutions, in diffuse solar climates. The only niche market will be engineering requirements for concentrating solar thermal that cannot be achieved at all with 1 sun exposure. In this case being "possible" vs "not" could be justifiable.

william-fitch-22587: You are right, CPV is only useful in areas with good DNI (Direct Normal Irradiance). This is about 1/3 of the US, ½ Saudi Arabia, and about ¾ of Australia. In Europe this would include a lot of Spain and Italy, and in Asia, most of India and a good section of China. These are just some of the areas with good DNI. I predict that the market will become segmented into three areas:
1) Areas with good which can use tracker where CPV will dominate.
2) Areas with bad DNI were inexpensive thin file panels will be the norm.
3) Areas that either don't want to use trackers (e.g. residential rooftops) or have average DNI
It is good to see more strong companies in the CPV market. Other technologies to watch are Morgan Solar's low profile concentrator (www.morgansoalr.com) and the Rainbow Concentrator by Sol Solution (www.sol-solution.net) which should have SYSTEM efficiency over 40%.

Low concentrators are less sensitive to directness of sunlight as well as aiming precision and quality of optical elements, etc. On the other hand, one has to be able to produce acceptable quality optics for something significantly less than $160 / square meter to have a chance of competing with ordinary c-Si modules. Another issue is weatherability - curved reflectors have a larger wind print and have a disturbing resemblance to a snow shovel. Also moisture on a mirror or fresnel lens tends to act as a diffuser. High concentrators can get by at something like $350 / square meter but, as noted, the size of the applicable market is substantially smaller.
