| SunPower: New, High Efficiency Solar Panel |

Photovoltaic systems are great, especially when you are in a very sunny location. But they are still extremely inefficient at converting light intoelectricity. SunPower, a manufacturer
of solar panels, has announced a new, high efficiency panel that is 22 percent efficient. The
company expects to have these new panels commercially available in 2007.
Compared to the numbers on other systems, 22 percent efficiency seems pretty unremarkable. But, considering that the source input is free, it's the
increase over previous technologies, not the system efficiency that is the mostimportant. These panels are able to generate up to 50 percent more thanprevious generations of solar panels, and that's a more impressive number.
According to the company's press release:
"The new SPR-315 solarpanel enables our customers to generate more power with fewer panels -maximizing energy production while reducing installation cost. A typical 4 kilowatt (AC rating) solar system requires 30 conventional 160 watt panels and covers 410 square feet of roof space. Our new SPR 315 panels produce an equivalent amount of power using only 15 solar panels on 265 square feet."

Do you have 7.5KW-20KW solar solution for mobile base station power?
Help me !!!!!!!!!!!!

Hay im doing a science fair question it's does pollutionn effect the efficiency of a solar panel ?
If u have any info please let me now im in 7th Grade and its a school science fair.Thank you !!!!!!!!!!

Hi, I'd like to know what is the cost per kilowatt.

Would appreciate if you could supply names of reputable manufacturers who could supply panels for over 5,000 housing units in a emeging economy.
Thanks

I am trying to figure out how to detemrine a cost for solar panels to support new homes to be constructed in the northeast and how many paels it would take to provide approximately 6000 kwh per year. I am looking for high efficient panels to reduce amouont of space consumption on roofs.
Thanks Bob
yeah

Science, technology gadgets and...baby seals. We're in a bit of an eco-mess, but we've got the brains to lick any problem. And that's why EcoGeek.org publishes up to ten stories daily about innovations that are saving the planet.
And if that sounds interesting to you, then congratulations, you're an EcoGeek.

This increase in output will enable more power in a smaller area, thats good.
How about basing the price of PV output on the TRUE power that is derived in the real world, not some idiocratic flash test under laboratory conditions that are never seen on someones roof top!!
And this comment comes from someone who has lived off-grid for 3 decades and has installed maybe, 1500 systems in that same period.
PV is great, imagine power from sunlight!!! But still too expensive for the average Joe.
