Hi all,

I've researching on manufacturing costs for Solar Panel, and it seems
to hover between 1 to 2.5$ / watt.

I'm curious though how the scalling on this works... the numbers out
there seem to be averages, but would there be much of a difference for
a 60 / 70 or 75 panel?

Regardless of the cost, the problem is that you get no output at night
when you need it most (and little in winter when you also need it most),
or even on cloudy days.

In short, unless you're seriously off-grid, PV Solar is an utter waste of
time and money.

Im curious as to where you got the manufacturing costs from.
What type of Solar panels are being made for $ a watt.
The only Company who have ever claimed that are Nanosolar
and theres no evidence to back that claim.

Anyway, the manufacturing costs are not whats important, its the cost
per watt that you can actually buy.

And they're very coy about it. I.e. won't tell !

$ / peak watt is more normal and that excludes fitting, maintenance and

True. Do you fancy paying $-2 / kWh ?

Actually I found reference to quite a few who made that claim...
unless they are already out of business?

- AVA Solar Inc. will start production by the end of next year on the
technology developed by Colorado State University. The new 200-
megawatt factory is expected to employ up to 500 people and will cost
less than $ per watt. The cost to the consumer could be as low as $
per watt, about half the current cost of solar panels.  Source: New

- 1366 Technologies has raised $2.4 millions to build a pilot solar
cell plant in Lexington, Mass., Rather than design new materials in
pursuit of a solar cell efficiency breakthrough, 1366 Technologies is
focusing on manufacturing improvements around silicon cells. A
combination of two manufacturing technologies will allow it to make
polycrystalline cells 25%more efficient at converting light to
electricity. Its goal is to produce solar cells at one dollar per
watt, or 10 cents per kilowatt-hour by 2012, which is about half the
manufacturing cost now.  Source: MIT spinoff shoots for solar power at
$ per watt, Martin LaMonica , News CNET

- The success is only partially attributable to UT. It is much more a
tribute to the ingenuity of Ohios scientists, engineers and
technicians who brought major expertise in glass handling, glass
coating, and manufacturing to help solve the many challenging issues
that needed to be resolved before such a new technology could be
brought to market. First Solar, now employing over 600 in Toledo, I
understand, announced this spring that their manufacturing cost was
$.25 / watt which is by far the lowest in the industry. First Solar,
now the worlds largest manufacturer of thin-film solar modules has
realized what scientists have been predicting for several years, that
second generation solar modules, not based on silicon wafers but thin-
film coatings on glass or metal foil, will lead in reducing the cost
of solar power in America and the world.  Source : Alvin D. Compaan,
