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.
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.
"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.
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)
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
Researchers at Lawrence Livermore National Laboratory have published two physics-based models for the selective laser melting (SLM) metals additive manufacturing process, so engineers can understand how it works at the powder and scales, and develop better parts with less trial and error.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
