beat up the bankers

I too am frustrated at the banking bailout.  I suppose we should try look on the bright side and say that having the bankers pay tax on their fat bonuses does help us all in the long run.  Back to the point....cheap solar cell installations are probably OK in the short term but I would worry about maintenenance, longevity and the environmental impact of disposal.  Japan is doing a decent job at reducing power consumption and so maybe other countries should follow suit as there is no really clean power source yet.  Anyway I better get back to work developing this fusion reactor project.

Douglas, you have hit the nail at the right place !

When it comes to the technologies that are going to benefit the whole world , the politics, the country borders and those import restrictions or add-on tariffs should not come in the way. The technology should be allowed to permeate freely across the world and organizations like UN should take a lead in it.

 

On the quality of the product point, If Chinese solar panels have some shortcomings , may be some US entrepreneurs should help them improve on those before importing them -this may still prove to attractive in terms of the final product cost. Just charging some additional duties on these products to discourage their import is not the answer.

What I read about in a comment in a Design News blog was failures due to wires inside the cell bank assemblies having no slack at all, so that thermal expansion caused the connection to fatigue and fail. What I have observed on other electrical products made in China is a similar thing, wires as short as possible with no slack to allow for even a bit of thermal expansion of the assembly. 

Of course it is entirely possible that the problem was realized and the assembly instructions modified. Corrections do sometimes get put into effect. That would eliminate the failure mode.

The wiring failure would not show up in testing of the individual assemblies because it was only when a bunch of them were in a panel that the improper connection was made. Also, that was about two years ago, so things may have changed.

@william. I have not heard of early failures. In fact, the increasing demand arose from the fact that the solar cells are being consumed by companies who are engaged in the installation of entire systems. The solar cells and panels have enjoyed multiple reorders from the same comapnies which would imply that the products have a good standing with middleman firms and customers. I would like to read of any failure trends as I am also a component engineer involved with reliability issues. Please forward any information you have on Chinese manufacturered solar goods failures. Thanks for responding. If there is a failure trend of considerable merrit, let's get that information published ASAP. Thanks for any and all assistance on this regard.

Purchasing lots of solar arrays from China at their artificially low price is an interesting idea, but there are a few problems that you have not brought into the discussion. One very large problem is product quality. I define product quality as the ability of a product to meet it's specifications for a period of time long enough for me to at least recover the value of the purchase price. It seems that "a few" of the made in China solar panels fail in that account, mostly through little things sucj as poor solder joint quality, or interconnetion wires cut just abit to short, so that they come loose after a few dozen temperature cycles.

So the question is "is a half priced array that fails after thre months a good value?" If the purchase was government subsidized on our end, then we have a case of "what now?" as we wonder how to make the non-functional solar array work again. It really does not matter much as to how these defects become so common, what matters is the amount of waste , both money and resources, that comes from purchasing based on initial price alone. But I would wager that product lifetime was never part of the discussion.

I was furious when I heard we (the U.S) were adding tariffs to China's solar cells and panels.

Yes we will lose some U.S. based cell and panel manufacturers who's business models are pretty shaky to begin with (manufacturing silicone products in the U.S. - dumb idea) but we will more than make that up on the installation/maintenance/repair segment of the solar industry.

With solar cell based energy systems being finically viable for the first time ever (without tariffs) the installation/maintenance/repair segment of the solar industry will explode. Too bad our dumb lawmakers only listen to one side of an argument.

Its bone-headed regulatory moves like this that are helping destroy what's left of this country.

You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically. Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions? Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
