Dear folks: We have been using 175W 24V Suntech modules for the past 18-24 months, mostly for one and two module water pumping systems for livestock. No problems to date.
We get LOTS of solicitations from Chinese module manufacturers to purchase their modules; sometimes they only offer a two or five year warranty. We only want to offer UL listed products, so that leaves a lot of 'em out of the game.

They seem dependable, haven't heard of any problems with them. Earlier in the year they were a low-cost choice for very cost-sensitive projects, but they were a 1st choice for very, very few dealers. Lately, with all PV prices tumbling, they've been even less attractive. I think the immediate future for Chinese modules will be developing country projects, and very large projects where price points matter more than a dependable track record or possible warranty service in a decade or two.

Joel Davidson Chinese Solar Production and Capacity Despite only having 140MW of solar projects installed, China was the leading manufacturer of solar cells in 2008, with 30% of global production. In 2008, China produced 2GW of solar cells, up from 1GW in 2007. In addition to producing PV cells, Chinese companies have produced 3GW of modules, up from 1.7GW in 2007, and 13,000MT of Wafers, up from 11,800MT in 2007. _______________________________________________ List sponsored by Home Power magazine List Address: RE-wrenches@lists.re-wrenches.org Options & settings: http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org List-Archive: http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org List rules & etiquette: www.re-wrenches.org/etiquette.htm Check out participant bios: www.members.re-wrenches.org
