Solar Shingles A First In San Antonio

Posted on June 20, 2012 by QuestPoint

Today, Dow Powerhouse announced the first installation of its cutting-edge Dow Powerhouse Solar Shingle roof system in San Antonio. Bobby and Sarah Ross waited over a year to be the first homeowners in Texas with a Dow Powerhouse solar roof.“This is an exciting day for us to be a part of the first Dow Powerhouse solar roof installation in Texas” In 2011, The Dow Chemical Company (Dow) installed a Dow Powerhouse system in Katy, TX as part of an employee contest before the product was made commercially available. The Ross’ family-owned business, Ross Electric Company, was chosen to connect POWERHOUSE below the rooftop. The family was able to see the installation hands-on, and decided to be one of the first in the country to install this total residential roofing solution that not only protects like a standard asphalt roof but also generates solar electricity, turning the roof into a source of value and savings.

“When I saw the seamless integration of the Dow Powerhouse Solar System, I knew it was something worth waiting for,” said Ross. “I am proud to invest in my home with such an innovative and good-looking product. I expect that my POWERHOUSE™ roof will reduce my utility bills by about 40 percent and will increase my home value overall.” BELDON Roofing Company, the exclusive Dow Powerhouse Authorized Dealer in San Antonio, worked directly with the Ross family to custom design the solar roof array to align directly with the family’s budget, roof design and energy goals.“This is an exciting day for us to be a part of the first DOW POWERHOUSE™ solar roof installation in Texas,” said Brad Beldon, President and CEO of BELDON Roofing Company. “We are seeing the way San Antonians think about their roof change now that they have the option to purchase a smart roof system that goes to work for them and pays for itself.”

The Dow Powerhouse Solar Shingle roofing system is offered to San Antonio homeowners as a packaged turn-key solution. It includes:A custom designed array of shingles to fit the individual homeowner’s budget, roof design and energy goals, a DC-to-AC inverter that feeds the home’s power needs or can be returned to the power grid and a monitoring system accessible from any internet connection, showing real-time energy production and generation. Made in the United States and backed by a 20 year warranty from Dow, the Dow Powerhouse Solar Shingle is also certified as both a solar and roofing product. It has received seven performance and safety certifications, including the backing of Underwriters Laboratories (UL), International Code Council Evaluation Service (ICC-ES) certification and is proven to withstand rain, hail and wind uplift.

Stanford Finds Future Of Solar Power Is Bright

Posted on June 17, 2012 by QuestPoint

Nearly everyone thinks that generating electricity via solar power is good for the environment, but there’s much less agreement on whether it makes sense from an economic point of view. At what point will solar power be competitive with electricity generated by conventional, fossil-fuel plants, and how long will subsidies need to remain in place before the solar industry can stand on its own? Those are some of the questions addressed in “The Prospects for Cost-Competitive Solar PV Power,” a new working paper by Stefan Reichelstein, William R. Timken Professor of Accounting at the Stanford Graduate School of Business, and Michael Yorston, graduate student in the Department of Management Science and Engineering at Stanford University. Their paper breaks new ground in studying the life-cycle cost of electricity generated by solar photovoltaic, paying particular attention to key factors such as location, public subsidies, and the long-term learning effects in manufacturing solar panels.

Concerning the future, and this may sound like a pun, the future of solar PV looks rather bright. The industry has consistently been able to lower the cost of solar panels. If this trend can be maintained for the next 10 years, and if subsidies are continued for that period, there is a real prospect for solar to become cost competitive on its own (that is, without a subsidy), at least for commercial installations. Utility-scale installations will take longer to become competitive; possibly 15 years, though it obviously becomes murkier to make projections that far into the future.

Renewable energy and solar in particular remain rather controversial in the public debate about energy policy. Passions have been running high. What motivated me is the bewildering range of statements you have out there regarding the cost effectiveness of electricity based on solar PV. Given the range of opinions, I wanted to do my own analysis. I’m looking at it from the point of view of a business economist who is interested in measuring the life-cycle cost of this abundant energy source.

2013 Solar Challenge Announced

Ford Using Solar Power To Make Electric Vehicles

Posted on June 16, 2012 by QuestPoint

Ford just announced in its annual Sustainability Report that it has reduced the amount of energy required to produce each vehicle in its manufacturing facilities by 22 percent in the last six years. The company also announced plans to reduce usage another 25 percent on a per-vehicle basis by 2016. Decreased energy consumption during vehicle manufacturing is just one highlight of Ford’s 13th annual Sustainability Report. The report – “Blueprint for Sustainability: Accelerating Ahead” – is a comprehensive showcase of the company’s efforts to tackle a myriad of sustainability challenges in a rapidly changing world. Other successful initiatives featured include reductions in water use, waste-to-landfill and CO2 emissions as well as improvements in vehicle fuel economy and safety. “Sustainability has moved from the periphery to the center of our strategy for succeeding in the marketplace and helping to address global challenges,” said Robert Brown, vice president, Sustainability, Environment and Safety Engineering.

“Our sustainability report is far from a bunch of tables and charts,” said John Viera, global director, Sustainability and Vehicle Environmental Matters. “Anyone who spends any amount of time with it will truly get a sense of just how committed Ford is to supporting positive change and reducing the environmental impact of its products and facilities.”Consider the drop in energy consumption: The amount of electricity used to produce each vehicle in Ford’s manufacturing facilities has been reduced by about 800 kilowatt-hours – from 3,576 kwh in 2006 to 2,778 kwh in 2011. By comparison, average households in states like California, New York, Illinois and Michigan use between 562 kwh and 799 kwh monthly.

Ford’s progress has been achieved by investing in energy-saving practices and equipment. At Michigan Assembly Plant in Wayne, Mich., for example, the company uses a new “three-wet” paint application that reduces electricity use along with CO2 and Volatile Organic Compound (VOC) emissions. At the same plant, a new 500-kilowatt solar panel system has been installed to generate renewable energy for production of Ford vehicles like Focus and Focus Electric. Thanks to such efforts already in place and Ford’s commitment to making further progress, the company projects a continued drop in energy consumption – 25 percent between 2011 and 2016.

Scientists Tap Into Underwater Solar Energy

Posted on June 14, 2012 by QuestPoint

Scientists at the U.S. Naval Research Laboratory (NRL), Electronics Science and Technology Division, dive into underwater photovoltaic research to develop high bandgap solar cells capable of producing sufficient power to operate electronic sensor systems at depths of 9 meters.Underwater autonomous systems and sensor platforms are severely limited by the lack of long endurance power sources. To date, these systems must rely on on-shore power, batteries or solar power supplied by an above water platform. Attempts to use photovoltaics have had limited success, primarily due to the lack of penetrating sunlight and the use of solar cells optimized more towards the unimpeded terrestrial solar spectrum.

“The use of autonomous systems to provide situational awareness and long-term environment monitoring underwater is increasing,” said Phillip Jenkins, head, NRL Imagers and Detectors Section. ”Although water absorbs sunlight, the technical challenge is to develop a solar cell that can efficiently convert these underwater photons to electricity.”Even though the absolute intensity of solar radiation is lower underwater, the spectral content is narrow and thus lends itself to high conversion efficiency if the solar cell is well matched to the wavelength range. Previous attempts to operate solar cells underwater have focused on crystalline silicon solar cells and more recently, amorphous silicon cells.High-quality gallium indium phosphide (GaInP) cells are well suited for underwater operation. GaInP cells have high quantum efficiency in wavelengths between 400 and 700 nanometers (visible light) and intrinsically low dark current, which is critical for high efficiency in lowlight conditions.

The filtered spectrum of the sun underwater is biased toward the blue/green portion of the spectrum and thus higher bandgap cells such as GaInP perform much better than conventional silicon cells, states Jenkins. Preliminary results at a maximum depth of 9.1 meters reveal output to be 7 watts per square meter of solar cells, sufficient to demonstrate there is useful solar power to be harvested at depths commonly found in nearshore littoral zones.The U.S. Naval Research Laboratory is the Navy’s full-spectrum corporate laboratory, conducting a broadly based multidisciplinary program of scientific research and advanced technological development.

D’Angelo Plays Eco Arts Bonnaroo Music Festival

Posted on June 10, 2012 by QuestPoint

Rock the Earth, a national not-for-profit environmental organization that partners with the music industry, just held the largest music festival in the United States – the 11th Annual Bonnaroo Music and Arts Festival in Manchester, Tenn., June 7-10. Rock the Earth held a series of artist interviews and performances live on Bonnaroo’s Planet Roo Solar Stage, as well as a series of environmental films at the festival. To coincide with its environmental programming, together Rock the Earth and Bonnaroo held a cell phone recycling campaign that rewarded participants who recycled their old and unused mobile phones with free goodies and entry into the daily drawing for prizes.

Moderated by Rock the Earth’s founder and Executive Director, Marc Ross, the theme of this year’s performances and discussions on the Planet Roo Solar Stage were on “Social Change Through Music.” Attendees learned what inspires musicians to be activists, and explored the synergies between the artists that create music and music’s interconnectedness to the environment and world.

From Manchester, Tennessee the Newsfeed Resecher reported, “D’Angelo is back. The reclusive R&B singer made his first live U.S. appearance in 12 years at the Bonnaroo Music & Arts Festival early Sunday morning, surprising a few thousand fans during Ahmir “Questlove” Thompson’s Superjam session. “I’ve been waiting 12 years to say this ladies and gentlemen, D’Angelo!,” Thompson said as the crowd roared. It was his first U.S. show since 2000 and a prelude to an appearance at July’s Essence Music Festival and a European tour with many of the same players who backed him Sunday morning. D’Angelo played live in Europe earlier this year.”
