The solar industry continues to shine brightly

As costs of solar deployments drop, many are looking to get in on a piece of the action.  Solar shingles and solar windows are just a couple of the promising technologies likely to see mass production over the next few years.  However, traditional installations are also thriving.

Dell Computer just received a completed 130 kW installation of Solar Trees at its headquarters in Round Rock, Texas.  The installation was designed by Envision Solar, BP Solar, and Weitz Company.  Contracting was handled by McBride Electric.

The resulting parking lot, dubbed the Dell Solar Grove, both provides 50 shady parking spots and clean green energy.  The lot also features Envision Solar's CleanCharge solar charging stations using the Coulomb ChargePoint technology.  These stations will help charge current and upcoming plug-in vehicles, such as the Tesla Roadster or 2011 Chevy Volt.  The plan to use solar to charge EVs is also being championed by Japanese automaker Nissan, who looks to use solar to charge up its 2011 Leaf EV.

Also making solar news is the near completion of the Soto Next Generation Solar Energy Center in Arcadia, Florida.  Owned by Florida Power & Light Company, this 25 MW installation features 90,000 photovoltaic panels and will go online by the end of this month.  When it does go online, it will become one of the nation's single largest solar installations.  Together with centers in Martin County and at NASA’s Kennedy Space Center, Florida will be shortly getting 110 MW of new solar generation capacity, boosting it to the second largest solar-producing state in the nation.

The new Soto Center will generate enough power for 3,000 homes.  FPL Vice President and Chief Development Officer Eric Silagy brags, "Large-scale solar projects such as FPL’s DeSoto Next Generation Solar Energy Center provide Florida with the opportunity to create and attract more clean-energy jobs and produce millions of dollars in new revenue for local governments while reducing greenhouse gas emissions and fighting the effects of climate change.  Large-scale solar projects such as FPL’s DeSoto Next Generation Solar Energy Center provide Florida with the opportunity to create and attract more clean-energy jobs and produce millions of dollars in new revenue for local governments while reducing greenhouse gas emissions and fighting the effects of climate change."

The plant's construction and maintenance have created 400 jobs.  The project will also generate an estimated $2M USD in annual tax revenues, which will help fund schools and other local services, starting next year.  The center is estimated to cut nearly 575,000 tons of greenhouse gas emissions -- the equivalent of taking 4,500 cars off the road.  It will also save 277,000 barrels of oil and 7 billion cubic feet of natural gas.

While costs are dropping, solar power costs per kWh remain higher than other forms of alternative energy.  Once that gap closes, expect solar to see an even greater jump in interest.  Until then projects like these will surely continue across the nation, albeit at a slower pace.

If you bothered to look closely at the pictures, you can see concrete surrounding the base of the support posts. This is similar to many of the lamp posts that are in parking lots, so I think it's safe to say that hitting one of these at 5 mph with even a SUV won't bring it down.

I don't see how this is any different than the lamp posts already in parking lots. Plus, considering the weight and area of the solar panels, I doubt it'll crush the top of a car like a giant steel lamp post will.

plus, think of the upshot to them being in that parking lot

higher skill rating for doing donuts!

I have to agree that if an SUV were to hit the solar post going, say 25 MPG, it could bring the whole thing down. An SUV weighs at least 5,500 LBS. Speaking of SUV, or any vehicle for that matter, is there even enough room to park underneath the half of the solar panels which are leaning down? Looking at the picture, it doesn't appear there is enough room.

If there is enough room, this is actually a good idea. I hope other companies copy it. Of course, companies will need to have 24 hour security camera surveillance. These solar panels are very expensive and there already have been numerous cases where thieves have gone up on roofs and stolen them.

BTW, when I first read the title, I thought Dell was the company providing power to 3,000 homes. DailyTech should rewrite their title.

I don't think I said anything about the driver going 5 MPH, most people drive a lot faster than that through parking lots anyway. I'm not sure what planet you live on, but most solar panels weight ~3 lbs per ft^2, not including support structure. Conventional parking spaces are typically 9'x19'. Judging by the shadow cast by the panels in the picture, each array covers 3.5 x 2 parking spots.

(3.5 x 9') x (2 x 19') = 1197ft^2
1197ft^2 x 3lbs = 3591lbs = 1.8 tons (not including support structure)

Yeah, you're right, it probably wouldn't even scratch the paint.

While my hypothetical situation may never happen, if it DID happen, the array would probably fall over to one side since it is supported only by a single centerpost. So it wouldn't likely kill the driver, but some unfortunately sap standing nearby. At the very least, it would crush the just about any car it falls on unless it has a roll cage...

Anyway, going back to what I said in another thread, I think this is a cool idea, making good use of the space. In fact, if I ever build a car-port, I may just do it using panels. I just hope my wife doesn't crash into it while doing her makeup. LOL

Yeah, people usually go faster than 5 mph, and no, you never said anything about 5 mph. I was giving an example, not trying to infer a speed into your argument. I'm just saying that it looks like they can take some small hits. You can't design for everything, and if it's up to current standards for steel lamp posts, it's hard to argue for more.

Sheesh, talk about blatantly putting words in people's mouths. I never said anything about it doing very little damage. I said that it's less dangerous to someone in a car than hitting a lamp post. It isn't just the weight, but the area that it would be spread over. That's why IMO the lamppost will more likely hurt someone who drives into it.

They'll come down, trust me. You'll pay at least $1500 for one too :P

My drift turned into a slide because there were sand littered on the corner :/
