Another one of Obama's little pet Greenie companies has filed bankruptcy


Evergreen Solar files for bankruptcy, plans asset sale

Evergreen Solar Inc., the Marlboro clean-energy company that received millions in state subsidies to build an ill-fated Bay State factory, has filed for bankruptcy.

Evergreen, which closed its taxpayer-supported Devens factory in March and cut 800 jobs, has been trying to rework its debt for months. The company announced today it is seeking a reorganization in U.S. Bankruptcy Court in Delaware and also reached a deal with certain note holders to restructure its debt and sell off certain assets.

The company also said it will lay off another 65 jobs in the United States and Europe, mostly through the shutdown of its Midland, Mich., manufacturing facility. That would leave Evergreen with about 68 workers according to a headcount listed in the bankruptcy filing.

sucks, for this company, particularly since there have been a couple of scientific breakthrough in solar power collection in the last year or so that can boost efficiency to about 80-90%, which is far better than the 30-40% most solar cells collect now. But alas it was not to be....

There are several serious problems with Photovoltaic solar panels .

First and foremost the cost...Expected cost of electricity produced from a PV system is equal to about 25 to 50 cents per kilowatt-hour (kWh)..And the expected payback is about 20 years...

A good measure of what that actually means is.
If a small window AC draws about 1000 watts (1KW) to cool a room .It will cost about eight cents an hour to run in Florida...or less than a dollar to provide a cool nights sleep...

Remember that most household electricity in America is 220 V AC split at 120v each side of neutral...
Solar panels, in full sunlight, produce low voltage DC, Direct current at about 14 Volts and about 7 Amps. They are designed to charge 12 volt batteries..So an array of solar panels each producing 14 volts are needed to charge each battery...So 14 panels each charging one battery would just about do it..

In order to produce household Alternating Current at 120 VAC a storage battery bank is needed
of about fourteen batteries all connected in series to provide sufficient voltage to run a DC to AC Converter/Regulator....These batteries must be recharged constantly either by banks of solar panels (the Worlds Most Expensive Battery Charger) or by Chargers using household power,..

These aren't just any battery but Marine Jell cell 12 volt batteries and are very expensive...A better choice would be to use golf cart batteries but the problem is they are 6 volts and twice as many batteries are needed for the same application.....Batteries are messy and dangerous due to explosive hydrogen gas generated when they charge and the sulphuric acid they use is highly corrosive...

So the choice is yours....short term cost versus long term payback....But remember batteries have a finite lifetime and need to be replaced occasionally .So a bank of 14 batteries replaced about every three years could run into a bunch of money...

The cost of electricity varies from area to area..It's most expensive on each coast and in the big cities...
The average cost of residential electricity was 12/kWh in the U.S. in April 2009,

New York it's about 14.55 /kWh
California about 12.0 /kWh
To Florida about 8.5 /kWh

The Southern and Northern boarded states have the lowest rate...
The New England States,Vermont,New Hampshire,Maine
all have higher rates than the national average rates...

Solar is becoming more viable, and cheaper than coal

http://hken.ibtimes.com/articles/197709/20110815/5-breakthroughs-that-will-make-solar-power-cheaper-than-coal.htm

1. Nano-templated molecules that store energy
MIT Associate Professor Jeffrey Grossman and others successfully created a new molecule called azobenzene, using carbon nanotubes to structure the molecules so that they "lock in" stored solar thermal energy indefinitely. These molecules have the remarkable ability to convert solar energy and store it at an energy density comparable to lithium ion batteries. As Grossman says, "You’ve got a material that both converts and stores energy. It’s robust, it doesn’t degrade, and it’s cheap.”

2. Print solar cells on anything
An MIT team led by professor Karen Gleason has discovered a way to print a solar cell on just about anything, using low temperatures and vapor as opposed to liquid solutions that are expensive, require high temperatures and degrade the substrate materials. The resulting printed paper cell is also extremely durable and can be folded and unfolded more than 1,000 times with no loss in performance.

3. Solar thermal power in a flat panel
Professor Gang Chen has been working on a revolutionary new way to make solar power — micro solar thermal — which could theoretically produce electricity at eight times the efficiency of the word's best solar panel. Solar thermal usually requires huge arrays of mirrors that heat up an element to run a steam turbine. Chen's system, which is about the size and shape of a typical solar PV panel, uses nanostructured thermoelectric generators that capture the heat differential created by the sun's light striking the top of the panel. Because it is a thermal process, the panels can heat up from ambient light even on an overcast day, and these panels can be made from very inexpensive materials.

4. A virus to improve nano-solar cell efficiency
MIT graduate students recently engineered a virus called M13, (which normally attacks bacteria) that works to precisely space apart carbon nanotubes so they can be used to effectively convert solar energy. The virus acts, in a sense, as a tiny machining tool to pattern the nanotubes, properly creating a jump from about eight percent efficiency to 10.6 percent efficiency — a jump of nearly one-third.

5. Transparent solar cell could turn windows into power plants
The world's cities are packed with miles and miles of glass. What if all that glass could be used to harness the sun's rays while maintaining their transparency? This idea has been out there for a while, but current attempts have resulted in terrible efficiencies (less than one percent) and tend to block too much light, rendering the window useless. Electrical engineering professor Vladimir Bulovic has made a breakthrough that could eliminate two-thirds of the costs of installing thin-film technology by incorporating a layer of new transparent organic PV cells into the window glazing. The MIT team believes it can reach a whopping 12 percent efficiency at hugely reduced costs over thin film solar cells.

I have no problem with using advancements in so called "green" technology as long as it's cost effective and efficient. Solar is becoming that.

All of those new discoveries are years away, if ever....Most often some glitch will make them impractical and they will never see the light of day...The most practical energy source I've seen so far is Hydrogen gas stored in Carbon Nanotubes...If during off peak hours Nuclear reactors were to break down salt sea water into hydrogen and Oxygen gases and store them in nanotube chambers.The excess generated energy would be stored and not lost as it now is ...As the gas accumulates it is compressed and turned into a liquid...It is moved by pipeline to depots where it is either used as a fuel to power automobiles and trucks or used in fuel cells to produce later electric energy and clean drinking water...Solar panels are for limited ,remote power applications charging batteries during the day and providing limited power during the night time hours...

Applications include road side signs,remote video monitoring,emergency warning systems,weather monitoring of remote sites..All require extensive battery backup with solar charging panels...

He's to busy not donating money to help the federal debt.

Sounds rather typical. It seems like most of his pet companies have been taking stimulus money, then shipping jobs to China before closing shop. It's probably a very convenient way to embezzle federal funds.
