Ill give u a lesson in electrics , power is constant, only the transformer loss counts.

P=UxI

P is Watts, U is voltage and I is Amperes

60w @ 12v = 5amps

60w @ 120v = 0,5 amps

WHEN THE VOLTAGE INCREASES THE AMPS DECREASES BUT THE POWER (WATTS) IS ALWAYS THE SAME EXEPT FOR LOSSES IN THE TRANSFORMER.

If you use 10 60w panels u will get 600w even if you step it up tp 1000kv (exept for transformer losses)

BTW Solar power is here to stay

• Panel pricing has declined by 50%.
it still would have to come down 90% more
thats the real story

The world will require an additional 12 to 14 terra watts by the year 2050- we produce around 14 terra watts on a daily basis now -in 1969 the worlds pop was 3.5 billion in 2010 it is approx 6.5 billion – we will ultimately need every WATT= EI we can produce – check out the output of Three Gorges Dam In China and or The James Bay Project in northern Quebec and relate that to the additional 12 Terra Watts we will require – an massive increase in Solar Power activity is a no brainer along with nuclear and wind.

Suntech is looking to vertically integrate and is looking to buy downstream solar companies. I think the biggest upside is in the small takeover candidates.

Acro Energy (ART:TSXV) is a California Solar Integration company.

4th largest residential installer in California and within the top ten in the country.
• Panel pricing has declined by 50%.
• signed a partnership agreement with SunRun to provide 100% financing to our customers, in any state that we chose to operate. .
• solar to the middle class with a product that can now be sold over the phone. 2010 is going to mark the mass adoption of solar.
• management team with industry leading talent acroenergy.com/investo…/

President, Nat Kreamer founded SunRun Solar and raised $110 million for the company, is one of the most respected names in the Solar industry.

So accurate!
you can't run a 120 volt 60 watt light bulb with a 12 volt 60 watt panel it would take 10 of them

do you get it now

Mr. Dickinson is not accurate about the 100 MW farm being only 10 MW. Watts are volts x amps with output being degraded by conversion efficiency which will be around 90%. So 100 MW of panels would have 90MW of output. However, power output ratings would take into account losses so a 100MW farm would produce that.

Thin film will make large inrodes into solar.

So if solar is not part of the answer to energy alternatives. what is?

Good report. Thanks. You have a typo, however. The name is Jeff Wolfe of groSolar, not "Jerry."

flip the switch off
PVs are not green nor smart
NOT green by the way there made.
it takes 1500° Centigrade to fuse the quartz to make the silicon ingots.
plus the Nitrogen Trifluoride used in the production of electronics and solar panels
real bad stuff
plus
Large scale solar like nellis afb is a cash cow.
thay spent $100m to save $1m a year. buy the way the panels last about 20 or so years.
so thats a loss of $80m.labor to run the scheem not included.
plus advertised and end use power ie. out put is 1/10th of at the end use. 100 mega watt @ 12 volt is 10 mega watt @ 120 volt in other words thay count each 12 volt panel it takes 10 to make 120 volt.
