Woodbury warming to solar energy

startribune.com -- Last month marked the first anniversary of Woodbury's new Public Safety Building -- and the arrival of a new source of electricity that enables police, fire and emergency workers there to do their jobs.

Workers spent the weekend before Halloween hoisting 185 solar panels, each about 3-by-4-feet in size, atop the building on the roof over the parking garage. Then they worked several days to get the system wired and operating.

The solar array will generate about 40 kilowatts of power under ideal, sunny conditions, "so it's a pretty good size," said Rick Moats, project engineer with Adolfson & Peterson Construction, who led the installation crew.

The solar panels will not only generate power for the new building, but the city's bottom line cost of about $40,000 will bring a return in

Good for Woodbury!

Since installing solar panels on the roof of our home, we have generated 70% of our consumption. Some Spring & Fall months our electric bill is $6 (the cost of being connected to the grid).

As the technology improves and prices come down, solar will become more prevalent in our energy needs.

The photovoltaic technology is not quite there to make each household energy-independent, but it could be.

With new energy conserving appliances and a shift to "lightweight" LED lighting, we could be, practically speaking, independent if it weren't for a couple of things:
1. Old-school thinking that says that houses should be "little boxes made of ticky-tacky".
2. Homeowners Associations that mandate that every house "all look just the same".
3. Architectural standards that mass-produce ticky-tacky houses in order to maximize profitability without regard to sound energy-efficient design. Not the architects fault, necessarily, as much as the city planners that are afraid to face the angry mobs of neighbors who don't want to see non-ticky-tacky houses in their backyards.

Here is the Little Boxes song, btw.

"The United States alone has about 69 billion square feet of appropriate residential rooftops that could be generating electricity from the sun," Stevens said. "The sunlight falling on those roofs could generate at least 50 percent of the nation's electricity, and some estimates put that number closer to 100 percent. With earth-abundant technology, that energy could be harvested, at an enormous benefit to consumers and the environment."

Atwater, a physicist at the California Institute of Technology, and Stevens, a chemist with The Dow Chemical Company, lead a partnership between their institutions to develop new electronic materials suitable for use in solar-energy-conversion devices.

Atwater and Stevens described development and testing of new devices made with zinc phosphide and copper oxide that broke records for both electrical current and voltage achieved by existing so-called thin-film solar energy conversion devices made with zinc and copper. The advance adds to evidence that materials like zinc phosphide and copper oxide should be capable of achieving very high efficiencies, producing electricity at a cost approaching that of coal-fired power plants. That milestone could come within 20 years, Atwater said.

Stevens helped develop Dow's PowerHouse Solar Shingle, introduced in October 2011, which generates electricity and nevertheless can be installed like traditional roofing. The shingles use copper indium gallium diselenide photovoltaic technology. His team now is eyeing incorporation of sustainable earth-abundant materials into PowerHouse shingles, making them more widely available.

New Solar Panels Made With More Common Metals Could Be Cheaper and More Sustainable.

With enough sunlight falling on home roofs to supply at least half of America's electricity, scientists today described advances toward the less-expensive solar energy technology needed to roof many of those homes with shingles that generate electricity.

Shingles that generate electricity from the sun, and can be installed like traditional roofing, already are a commercial reality. But the advance ? a new world performance record for solar cells made with "earth-abundant" materials ? could make them more affordable and ease the integration of photovoltaics into other parts of buildings, the scientists said.

The new photovoltaic technology uses abundant, less-expensive materials like copper and zinc ? "earth-abundant materials" ? instead of indium, gallium and other so-called "rare earth" elements. These substances not only are scarce, but are supplied largely by foreign countries, with China mining more than 90 percent of the rare earths needed for batteries in hybrid cars, magnets, electronics and other high-tech products. Atwater and James C. Stevens, Ph.D., described successful efforts to replace rare earth and other costly metals in photovoltaic devices with materials that are less-expensive and more sustainable.

Solar Panel Market to Advance by 15.3% through 2015.

A recent report released from publisher Infiniti Research points to further growth for the global solar panel industry.

The report finds advances in photovoltaic (PV) technologies will help the global solar panels market to increase by a compound annual growth rate of 15.3% between 2011 to 2015

>>Under the deal, the project's cost is $290,466.<<

>>but the city's bottom line cost of about $40,000 will bring a return in energy savings estimated at more than $100,000 over 20 years, said Bob Klatt, the city's director of parks and recreation.<<

So, Mr City Administrator, at the end of 20 years, the taxpayer is still out $190,466? Plus interest. Or is the projection $230,466 unrecovered expenses to own a 20-year-old solar capture system in 2032?

At a cost of $1/watt of capacity, this is cheap. Without the incentives, the system is over $7/watt which is not economical.

As the price of solar goes down we'll see more and more small size installations of solar panels. I've already noticed a few in my general area and when I do I think - well that's a pretty good use to put that land to that would otherwise go unused.

"Under the deal, the project's cost is $290,466. Two Xcel Energy rebates and federal tax credits will go to Adolfson & Peterson, which will initially own the system, Klatt said. That allowed the cost savings from the rebates and tax credits to be passed on to the city.

The city will buy the power produced by the system at $416 per month for six years. It will then buy the whole system for about $10,000. The money comes out of the building's operating budget."

There is no return on investment for the city. It didn't invest anything. There is no capital outlay. The solar panels and entire system are owned by an independent third party that is selling the electricity produced by the system to the city. The cost of the electricity is less than it was for the building before the installation.

Very good financial engineering.

Commercial accounts here in San Antonio, TX get up to $100,000 rebate from our utility company (City Public Services) for putting solar panels. They save money on utilities and generate income by selling energy back to our only utility company.

Articles on economics issues bring comments of "what impact on gas prices"?

Where are these comments on solar?

Total waste unless you believe in global warming that is caused by C02.

If you do believe in this, read about the real solution: Biochar.
