5 kWh/day ONLY in the southwest. The annual average for USA is 4 kWh/day.
Thats NREL data, good for most areas up to 40 degrees North.
But you have to remember the weak link in the chain, which is that
December/January average will be just over 2 kWh/day. Adding trackers will
improve that to 3 kWh/day.

The assumption was that the noontime capability was one kilowatt

In general, you get five kwh or less per day for each noon kilowatt.

See <http://www.tep.com/Green/GreenWatts/SolarOutput.asp> for current
real numbers.

With Don's number - 5kwh/kw/day - this amounts to 730 kwh. At 10c/kwh
that is $73. Similar to your 600 kwh/day calculation.

Brilliant. Slightly over a half million dollar investment with a 26K/yr return,
about 4.5% return a year. Subtract from that maintenance, property, and power
transmission preparation and you might as well take the half million and burn
it. Would be a cheaper endeavor.

And the interest rate was.....???

At 4.5%, the investment would be utterly and totally pointless.
Above that, it is a gasoline destroying money sink rathole.

Also, with the imminicy of CIGS, there is no way in hell that existing
"eight track TTY" pv installations will still be in use even five years
from now. So ANY long term breakeven projections are worthless.

My numbers were off hand and rounded. They were based on converting
electricity to fuel (hydrogen) at an absurd 100% efficiency (unobtainable
best case) and comparing it to the rough cost of gasoline, a fuel to fuel
comparison. In no way does a multi-hundred thousand dollar investment pay
off unless gasoline gets to about $20 a gallon. Or, as Don likes to say its
the equivalent of turning your dollars into pesos. My biggtest issue was not
the exact conversions values or even a typo but the fact that the original
post came from a TV report with the usual bimbos trying to talk technical.
They rarely get anything right.

I wonder for how much they can sell their hydrogen produced in their
plant. According to an article about hydrogen price projections (even
though from 2004), the market price of this gas is about 100 $/kg plus
cylinder rental (http://www.dotynmr.com/PDF/Doty_H2Price.pdf). I don't
think that this price dropped during the past years to a few dolars
per kilo.... This means that the business simply might be in selling
the hydrogen to this price which is much more than you can get just
selling the electricity.

I think I misinterpreted this publication and in particular the
hydrogen price. Reading it again, the cost of $100/kg of hydrogen is
too high for being used as fuel in cars and the real cost of technical
grade hydrogen is rather in the range of $3/kg. As far as I know, most
of the hydrogen today is produced by thermolytic methane reforming and
electrolysis cannot (or could not in the past) compete with this
process. The production of hydrogen by electrolysis consumes in the
range of 65 kWh/kg (http://www.evnut.com/docs/acp_fc_pollution.pdf)
which means that with a 146 kW solar pannel it should be possible to
produce about 2.24 kg of hydrogen per hour or 22 kg per day
(considering 10 hours production per day). Let's say the 22 kg of
hydrogen could be sold for a price of $3/kg, the profit would be $66
per day. This is almost the same conclusion Bob got comparing the
energy of the produced hydrogen with the corresponding gasoline price.
There really seems no way to save $43,000 per year..... Or we are all
wrong Smile

Well let's see: 210, 180 Watt panels is 37.8kW? Not 146kW. So, where does
that number come from? But, even using that high 146kW number the energy,
at best, is equal to about 600kWhr each day or 24 hour period. If that
could be converted to hydrogen at 100% efficiency which isn't possible, it
would equal the energy of 17 gal of gasoline! Wow! That's about $50 per day
yield! But these clowns claim $43,000 per year savings??? So why does none
of this add up? As usual, its all hype and bull shit not based in reality,
generated by a marketing department or worse, a local TV station by people
who don't know a watt from a cheeseburger.

Is it possible that the 146kW number is supposed to be 146kWhrs, the total
amount of energy collected in one day? If so, the prolific yield would equal
abut four gallons of gasoline per day. Now I'm really impressed, that's
about $12 a day. What an investment! Checking numbers is important!
