Green Power Breaks Records in the West
5/10/2013

Solar energy generation in California is expected to rise sharply during the second half of 2013, coming from utility-scale plants such as the California Valley Solar Ranch in San Luis Obispo. Here, 140 megawatts were brought online in December 2012. By December 2013, the project is expected to deliver its full capacity of 250 megawatts.   (Source: US Department of Energy/NRG Solar)

I agree that for consumer or commercial buyers, higher quality is better. And I was afraid you'd say that, Mydesign--that the "cheapest is best" philosophy is so widespread. Apparently, from the manufacturer's/seller's standpoint it makes for higher profits.

"I think part of the problem is also because consumers, at least here in the US, have been taught that cheap is good and cheapest is best."

Ann, that's there everywhere. Those who are going behind such cheap goods have only some short term goals.  But for long term goals, only quality products can sustain and have better yield.

Mydesign, some Chinese manufacturers do make quality products. There are many of these products in the US. There are also many cheaply made, poorly made products that don't last or even work right. A similar range of quality used to exist in the US, before most of our manufacturing went to China. The difference depends at least partly on what the US-based/global company requires of those manufacturers. I have noticed that the low end of "cheaply made/doesn't work right" products has dropped even lower since we offshored so much manufacturing. I think part of the problem is also because consumers, at least here in the US, have been taught that cheap is good and cheapest is best.

"Those USA companies were killed due to China prices. Perhaps, if the panels are cheap enough from China... then the ROI will be short. And the world will benefit."

Cabe, when we compare Chinese and rest of the world products in terms of price and quality, always china is out of the list. They cannot make quality products at a dam cheap price.

Stay tuned, Cabe. I'm working on a blog about China's solar panels, price consequences, etc.

Mydesign,

Those USA companies were killed due to China prices.

Perhaps, if the panels are cheap enough from China... then the ROI will be short. And the world will benefit.

However, ROI has to factor in the energy used to produce the panel.

"After the 6 year wait period, how much longer will those panels function? Will maintenance be costly to a point where the only option is to junk the panel? Keep in mind, after 6 years or a decade, parts may be impossible to come by"

Cabe, what I understood is under normal situation, panels can function well up to 20 years. But the tubular battery has to be replacing once in 5 years and other electronics parts like UPS/Inverter functionality cannot be predictable.

Mydesign,

After the 6 year wait period, how much longer will those panels function? Will maintenance be costly to a point where the only option is to junk the panel? Keep in mind, after 6 years or a decade, parts may be impossible to come by. If you bought a panel from USA based Solyndra or Flebeg Solar U.S. Corp, you are out of luck. They both went bankrupt.

I would like to know if solar is useful or not. I will have to do some research... (I'll make a post too)
