We've seen a few massive solar farms pop up out west, but it looks like Southern California Edison is taking a different approach: instead of cluttering up the desert, the company plans to build a distributed solar array on the rooftops of commercial buildings throughout SoCal. The plan is to spend $875M over five years to cover about two square miles of rooftop with the panels, which will alleviate stress on the grid by generating around 250 megawatts of juice, as much as a small power plant. That's enough to light up 162,000 homes, but it's still a little short of the record 280-megawatt Solana installation planned in Arizona -- come on, Cali, let's see a little fight.

Printed solar cell tech keeps getting closer and closer to reality, with a Massachusetts company called Konarka Technologies today announcing that it's now able to manufacture solar cells using inkjet printing. There's not a ton of information available about the process, but Konarka's already demonstrated it and published details in a trade journal called Advanced Materials -- which sounds like scintillating reading, if you ask us. Konarka says the process makes fabbing solar panels extremely easy, since it doesn't require a clean room, and the resulting cost reductions could lead to an increased number of applications for solar power. Of course, the economics of inkjet printing have lured more than one company to the dark side -- we wonder if Konarka is eventually going to start selling solar ink cartridges for more than the printers themselves?

We've heard plenty of promises about low(er) cost solar panels, but it looks like the heavily-funded upstart Nanosolar is actually getting around to churning out what it says is the "world's lowest-cost solar panel." As The New York Times reports, that feat was achieved by taking a different approach to lowering the cost than most -- namely, by reducing the manufacturing cost instead of trying to increase the efficiency. As a result, by using a new process that effectively "prints" photovoltaic material onto an aluminum backing, the company says they can profitably sell the solar panels for "less than $1 a watt" or, as The Times points out, the price at which solar energy becomes less expensive than coal. What's more, while Nanosolar itself is hanging onto one of the first panels for exhibit, and one is being donated to the Tech Museum in San Jose, Nanosolar is auctioning off one of the first three panels to be produced on eBay, where the bidding currently stands around $1,000. Anyone looking to actually put it to use may want to think twice, however, as the panel is being sold "as-is."

Astronaut Scott Parazynski pulled the short straw (probably on purpose: you know what these astronaut types are like) and had the task of repairing the ripped solar array on the International Space Station. Mission complete, as Parazynski managed to move the guide wires that caused the damage out of the way and "stitched" together the two and half feet rip, the whole time managing to avoid touching the panels and their 100 volt charge. It's the furthest any astronaut on the ISS had been outside the cabin, and as such it took an hour to get there on a 90 foot robot arm. What would we do without duct tape?

We've been inching closer to low(er) cost solar panels (for the mainstream public to enjoy) for some time now, and apparently, AVA Solar Inc. is just about ready to start cranking out units that "will cost less than $1-per watt by the end of next year." The technology was reportedly developed by Colorado State University's Professor W.S. Sampath, and production is slated to begin soon in a "200-megawatt factory" that could employ some 500 individuals. Of note, it was said that the "cost to the consumer could be as low as $2 per watt," but even that figure purportedly rings up at about half the cost of current options.

While you were busy watching Vladimir Guerrero take home the Home Run Derby crown two nights ago (not to mention the All-Star game last night), you may not have been aware that AT&T Park was feeding uber-clean energy back into the grid serving PG&E's customers throughout northern and central California. Sure enough, the home of the San Francisco Giants is now also home to 590 Sharp solar panels located in three separate areas of the stadium, which combine to generate some 120-kilowatts of electricity. The size of the entire array is reportedly "equivalent to approximately 40 residential solar systems," and while this system won't conjure up as much power as the CIS Solar Tower, it will certainly make good use of the ballpark during the off-season.

Tacking an LCD onto the exterior of a USB flash drive is nothing new, but CoMo Gadget's CM-1022 is upping the ante by allowing users to customize what's pictured on the screen. This less-than-attractive device is helped out by the ability to upload a logo or picture onto the built-in screen, which then flashes to get "maximum exposure" for marketers. Additionally, there's room for 4GB of mind-numbing press releases, Java games, or one-time use coupons, and considering that the display is reportedly solar-powered, a dab of sun should keep the flashing going 'til the wee hours of the night. No signs of a pricetag just yet, but unless you've got advertising on the brain, we'd steer clear of this one.

While we certainly applaud the designers at Spectrolab for developing a solar cell that's reportedly "twice as efficient as typical rooftop solar panels," we're stifling most of our excitement until it actually leaves the laboratory. Nevertheless, the Boeing subsidiary has apparently cranked out a cell that utilizes metamorphic materials and is "designed for photovoltaic systems that use lenses and mirrors to concentrate the sun's rays onto small, high-efficiency solar cells." The unique semiconductors used are said to resemble ones that adorn satellites and planetary landers, and can capture three layers of the solar spectrum versus the single layer that traditional solar panels collect. Unfortunately, it seems that the eventual goals for this thing are rather ho hum, as the crew only expects the cells to hit 45-percent efficiency within the next six or so years. C'mon folks, you've already got alternatives at 40.

It's not the first, but it is the, erm, latest solar paneled bag bent on keeping your portable electronics, portable. The Avorities Solar Panel Bag from Dunhill brings those staid Tumi looks favored by suits with the advantage of solar panels to charge a hidden battery. Sorry, Dunhill doesn't provide any detailed specs on the battery or such trivialities as charge time. However, if it's like other models, you can expect it to charge your cellphone in about three-hours assuming the bag's internal battery has been properly charged. The scratch, stain, and water resistant tote measures 38 x 27.5 x 12.5-cm and features magnetic enclosures and "iPod holes" on selected styles. What, you're not waiting around for a price are you 'cause they didn't tell us that either.

Update: Price found thanks to Millerand: £665 or $1,316... ouch.

Silicon Valley-based SunPower Corporation is looking to add a bit more juice to your rooftop, announcing its highest power and most efficient solar panel to date. The SPR-315 solar panel is based on the company's brand spankin' new Gen 2 solar cells, which have a rated power output of 315 watts and boast 22 percent photovoltaic (PV) efficiency -- that's opposed to the 7% to 17% common in most commercial PV systems. According to SunPower, that means you should get roughly 50 percent more power per square foot of roof area than the average solar panel, using half as many panels. Whether it'll also cost you half as much or not has yet to be seen, but we should find out by the time the SPR-315 solar panels are available in the Spring of next year, after we too have coated our country cottage in the stuff, and start contributing to -- not pulling from -- the grid.
