Greensburg green plan

[winnie]

I am truly _astounded_ by their JIL3000 modules. (See http://www.dbksolar.com/Specificatins.htm)

The panels are 62.5" by 32.5", for a surface area of 1.31 square meters.

The test conditions are specified to be 1000W per square meter irradiance. So the maximum power _in_ to a cell is 1310W. Yet the power output is _3000W_.

Wow. I'll take 5i!

Ok, this is an electricians forum, so whats wrong with this picture? Illustrated is a JIL 3000 solar panel, which according to the meter is producing 2.8KW...

Sorry the image is a bit big, but it makes it easy to see

Perhaps you could use the windmill to pump to a water tower?

Guess I am having a hard time figuring out how they are measuring current flow through what should be the votage connection to that meter.

Maybe the hold button might have something to do with it. Like it was pressed after being used in a different circuit and then someone forgot to release it for this test?

Or are you talking about the taped meter lead which makes it a safety issue?

Thanks for the input guys:

I have read all the solar scam internet sites involving DBK.


Testing their unit (by our professional electrical engineering staff)should be very "illuminating"

UPDATE:

The client was advised of this scam possibility to-day incuding the following "fishy"post from DBK:

"I forgot to tell you in my last email. Our panel gets 700 watts from the sun to our panel and the rest is electronic amplification to bring it up to 3000 watts.
We have a patent on the system."

The client did a crazy 180 and now has rush shipped a solar panel to us for testing.

Results should follow shortly.

Indeedy. Now as you say, they may have done something involving a hold switch, but it just looks sufficiently wrong on first look that I for one am leery.

Winnie has also pointed out that these panels are delivering more watts than the sun is delivering for the given area, so they are over 100% efficient...

700 watts in and 3000 out. Yea right.:roll:

Ghost I spent about the last 30-minutes looking into this and still have the same impression I had when I first read your post. I smell a rat and a scam. Please this doesn?t reflect on your integrity, I just don?t buy a word of the manufactures claims.

As I surf the web, I cannot find any credible source to the claim, in fact just the exact opposite. What I find is scam articles.

Here is the deal; the national average is 17% efficiency for solar cells. When the biz started 25 or 30 years ago it was about 8% So in 25 years very little advancement despite some of the worlds finest scientist working on the problem. Now here comes a small biz claiming 71% out of nowhere.

If this were true, and could be authenticated by science, this would be the greatest technological breakthrough in the history of physics, bigger than splitting an atom. It would solve all out energy woes and be a license to print money. If true it would send POCO, Coal, and Natural gas stocks to a miserable death and bankruptcy almost overnight.

So this companies claim is they made a 712% efficiency gain and can sell their system at 1/3 of their nearest competitors cost in 1/6th the space. Sorry, I don?t buy it. However if it does prove to be true. You can bet I will be in the IPO line to buy a truck load of stock. :grin:

neither do I (was that grammar correct?). I was just in a solar panel plant (which is an overseas plant of a US company) and these guys couldn't even power their own building with solar power. they need our poco and they had their rates 'subsidized' so that they can produce panels at a cheaper cost.
