How much CO2 is reduced by solar panels compared to how much CO2 is required to manufacture them?

I was reading an article that stipulated that much of the CO2 issues purported to be reduced were practically negligible when compared to how much CO2 was expelled in their manufacturing. The idea was that many of the attributes of Solar technology that relate to Climate change and going Green were in effect totally moot and considerably over-stated.

Is this true?
I’m not sure the article would help much even if I could remember where I read it.The comment that generated my question was more toward the general growth of the Solar industry – it was in the subtext as something like "and in all honesty there is little net CO2 reduction with Solar when offsetting against the amount of CO2 used in the mfg process, blah, blah,.." It wasn’t the thesis of the article and there was no other detail provided which is why I was trying to figure out the real meaning of it. My real intent here is that I’m considering working for a Solar company and am just doing some due-diligence on the industry – that statement popped in something I was reading but I’d have to look for it.

Thanks Violet for the detailed answer, although I’m not sure that provides a direct comparison of CO2 released. I think we would have to know how many KW’s of energy are needed to produce a Solar panel in order to net the difference against energy use avoided once in use.
