I want to know where is a right place to buy them. I have be reading about solar panel, and I need around 9k watts per hours of daylight. so, my question, Do I enjoy to buy it new because I own searched and I can't find nought cheaper than 9000 for the panels. Does anybody know if there is any place where on earth I can buy it cheaper?. thank you.
Answers:
Wow you get all kind of answers on that one that is no where on earth near what you be asking. lol Happens all the time. But some honest statements never the less.
You did not enunciate how many pinnacle sun hours you get a daylight in your nouns. In my area of Arkansas I draw from 4.5 to 5 hours of peak sun. So using 9,000 watts divided by 4.5 hours I would inevitability in my nouns 2,000 watts of solar panels. (may not be correct for your area).
Check out this net page. http://store.oynot.com/solar-electric-sa... . The price on these panels are 4.50 per watt which would be $9,000. However, self you are buying so many you attain free shipping (save I bet 300 bucks on just shipping) and could even parley them into knocking stale 5 cents or more per watt. They just have a sale for smaller quantity then that. It done the first of this month.
Tell them Don K told you so.

Dear sir
We are an solar panels exporter within china, we can supply you the solar product from 0.1w to 300w, for more information, pls email to colin944303(a)yahoo.com, i will email you more further information. Regards, colin
theres a new classmates of solor voltaic cell coming out in 2009 that will diliver 40% more power than the standard home use cell panel, they may cost as much as they do today buy at 40% more its worth the wait, plus the advancement being made if you do diside to "invest" they will be obsolite within 5-10 years but by then the system will enjoy paid for them selves, which surrounded by time they do. and if you get a steady twist, like we do here contained by northen indiana, get a coil turbine rated at 7k per year
Well....
(might not be exactly what you want to hear...I think you might want to loaf.....lemme explain...)
"Earth bound solar panels still remain significantly smaller number profitable to operate than competing fossil fuel alternatives, which are at present hovering around $2/watt, and the cost per watt of setting up a space base solar energy station seem even less profitable."
Part of your problem is that the panel made now...respond best to a wavelength ... (frequency/invisible color) ... that the AIR blocks a upright portion of as the sunlight passes thru it....Where you live will affect your solar panel's output....
This effect is call Insolation..."Insolation is a measure of solar radiation power incident on a surface."
http://en.wikipedia.org/wiki/Insolation
(when you look at that site... it mentions that 1370 watt/Sq meter is the suns power output measured here at the Earth. but when you acquire ground level you are singular left next to about 250watt/Sq meter. Oh and that's spread-out over the together electromagnetic spectrum.. visible & electromagnetic.. so...some of the wattage isn't even usefull to the solar panel....sigh.)
As a result, satellites seize GREAT response from solar panels.
"Using advanced solar panel in outer space, it may sooner or later be economically feasible (or even necessary) to grin the sun's seemingly infinite power supply back to Earth for broad consumption. "

(Microwaves are largely un-affected by the AIR so if we put solar powered Microwave generators up and enjoy them beam the power down as microwave get-up-and-go to reciever stations on the Earth)
There's hope tho.....
Pioneers at SA Solar have announced a core advance surrounded by solar panel technology - an acheivement that has resulted from over ten grueling years of research.
The South African Solar squad, headed by Professor Vivian Alberts of the University of Johannesburg, have developed an extremely thin metal alloy to be precise especially photo-responsive. This alloy can be used to construct solar panels simply 5 microns thick!
This amazing brand new alloy stands in stark contrast to traditional silicon photovoltaic cell, which are typically nearly a hundred times as thick as the unusual photo-responsive alloy.

Here's data on a solar home built by Chris Marnay, a post-doctoral fellow contained by the Energy and Environment Division. Marnay works for E&E's Appliance Standards Group. He creates computer models that project the impact of proposed DOE energy-efficiency standards for appliances on natural gas and electric utility companies.
http://www.lbl.gov/Science-Articles/Arch...
Marnay's solar-based system cost roughly $11,500 to build and install. It would have be cheaper to build a diesel or propane-fueled generator installation, but that would have entail environmental and other problems, including noise.
Oh BTW if you install a Large satisfactory solar panel array..you can get your electrical supplier to install a special meter that will allow you to SELL your surplus electricity to them! In that style you can defray the operating/install costs..But, the initial outlay of funds still falls on you.
I suggest you give it a touch time if you can......The new version of panels will get your..strike that....OUR..... dream more cost effective...
All this notes I looked up, has be part of my own investigation..... I too want the freedom of solar power!! My conclusions enjoy been that except installing a large plenty system to sell excess power to the power companies....afterwards the expense is not really worth it...yet...the unmarked tech...looks like it will manufacture the difference in price tho...so...I'm sitting fund (somewhat patiently) for the next contemporaries!!
Hope I helped....
