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)
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
