Military Goes Solar

Energy Department Loan Guarantee Would Support Large-Scale Rooftop Solar Power for U.S. Military Housing

September 7, 2011

Washington D.C. – U.S. Energy Secretary Steven Chu today announced the offer of a conditional commitment for a partial guarantee of a $344 million loan that will support the SolarStrong Project, which is expected to be a record expansion of residential rooftop solar power in the United States.  Under the SolarStrong Project, SolarCity Corporation will install, own and operate up to 160,000 rooftop solar installations on as many as 124 U.S. military bases in up to 33 states.  SolarCity expects the project to fund approximately 750 construction jobs over five years and 28 full time operating jobs.  Many of the jobs are expected to be filled by U.S. veterans and military family members, who will be recruited, trained and employed to install, operate and maintain the photovoltaic (PV) systems.

“This is the largest domestic residential rooftop solar project in history,” said Secretary Chu.  “This groundbreaking project is expected to create hundreds of jobs for Americans and provide clean, renewable power to our military families. It can also be a model for other large-scale rooftop solar projects that help America regain its lead in the solar industry.”

The project, which could create up to 371 megawatts of new solar capacity, includes the installation of residential rooftop PV systems on existing privatized military family residences and other privatized buildings, such as community centers, administrative offices, maintenance buildings and storage warehouses.  The project will provide low-cost, renewable electricity to privatized military housing and is expected to avoid over 250,000 metric tons of carbon dioxide annually.  The SolarStrong Project will have the added benefit of helping the Department of Defense (DOD), the single-largest energy consumer in the U.S., secure its energy needs from domestic renewable sources that are independent from the utility grid, at no additional cost to taxpayers.  DOD has a stated goal that 25 percent of all energy consumed by 2025 shall be supplied from renewable sources.

Reality of Community Solar

Can Community Solar Programs Bring Solar Ownership to the Masses?

Americans For Energy Leadership On 01.24.11, 

In Opinion, By McKenna Morrigan

Americans For Energy Leadership

http://leadenergy.org/

Community solar is a concept that has lots of cheerleaders. And what’s not to love? At it’s best, this market-based deployment strategy can expand access to clean energy, create jobs, spur local investment, and help drive down the cost of solar panels.
But while the concept of community solar has had strong support from policymakers and clean energy advocates for several years, actual community solar projects have been slow to materialize. Now, two statewide community solar programs and a host of other new state and local policies to encourage community solar may be catalyzing a wave of new projects. Will the reality of community solar live up to the ideal?

Community Solar Spreads the Benefits and Rewards of Clean Energy Investment
Community energy carries all the environmental, economic, and national security benefits of clean energy in any form, but with a distinct advantage. A review of research by Northwest SEED suggests that community energy projects deliver 2-5 times the economic benefits of projects built by out-of-state investors. And, in places that import electricity from outside the area, community energy can also keep utility dollars in the community, with multiplier benefits for the local economy. Community energy provides distributed generation, with associated benefits such as increased system reliability and resilience, lower peak power requirements, minimal transmission requirements and reduced line losses.


Examples of community energy began in rural areas of the Midwest, where farmers joined together to capture some of the benefits of the commercial wind development boom underway at the time. These projects blazed the “community energy” trail, developing novel legal structures and forms of financing, and proving that community energy could be a source of job creation and economic development.
But community wind has limited applicability, given the requirements of a strong wind resource, access to transmission capacity, and lots of open space to make a project financially viable. In contrast, solar photovoltaics (PVs) are well suited for modular applications of varying scales and can be placed on existing structures, making them a great fit for urban areas where retail electricity rates and demand loads are often highest.

Community solar is appealing in part because, despite broad interest among the public in solar energy, most people don’t have the ability to install solar PV on their own property. A 2008 study by the National Renewable Energy Laboratory found that only 22 to 27% of residential rooftop area is suitable for hosting an on-site PV system after adjusting for structural, shading, or ownership issues. And in places like New York City, where home ownership rates are especially low, only a small number of people have incentives to invest in solar PV.

Community solar projects address this barrier by decoupling solar PV investment from on-site generation. Owners of community solar contribute funds to pay for a portion of a project, and reap benefits proportional to their investment. Community solar projects can be installed on the property of one of the project owners, on a separate private site, or on a shared location, such as local or state government property. Owners can include renters, homeowners, local businesses, even utilities.

Early Projects Suggest Two Different Approaches
Only a handful of community solar projects are complete, with another handful in development, so no definitive model exists. But so far, projects fall into two approaches.
The first and more common is the utility-sponsored approach. These projects are legally owned by a utility, and individuals voluntarily contribute funds to help finance them, either up front or on a monthly basis. In exchange, contributors receive credit on their utility bill equal to the output of electricity from their portion of the investment. Early examples of this approach include the Sacramento Municipal Utility District (SMUD) SolarShares program and the Ellensburg, WA Community Solar Park. These public utilities have been very successful in using this approach to finance solar installation and the concept is spreading quickly.

Despite its popularity, the utility-sponsored approach has some significant limitations. According to an analysis by the New Rules Project at the Institute for Local Self-Reliance (ILSR), utility-sponsored projects can compare unfavorably to the economics of individual ownership. In some cases, contributors never even achieve full payback of their initial investment, making this approach much like other “green power” programs where utility customers simply pay a premium for clean energy. Only where there is a production incentive that generously rewards community projects (such as in Washington State) does this model seem cost-effective for contributors.

Still, for those who cannot invest in solar themselves, the utility-sponsored approach is often the only option. The second approach might be called a true community ownership model, where the risks and benefits of ownership are shared among individual participants, often through an ownership structure such as a cooperative or an LLC. This model is much stronger in concept, but it has proven very challenging to get off the ground, despite strong interest in many communities.

As David Brosch, lead developer of University Park Solar Community in Maryland, one of the first community solar projects in the country, said, “It took us over two years to develop our project structure and only two months to find our members.” The Clean Energy Collective’s Mid-Valley Solar Array in Colorado, a 77.7 kW community solar project, is another early and widely touted example of the ownership approach, which its founders hope to replicate around the country. Compared to the utility-developed approach, these projects have shown to be more attractive investments, with paybacks faster than would be possible through individual solar PV ownership.

$50M Towards Domestic Solar Manufacturing

Department of Energy to Invest $50 Million to Advance Domestic Solar Manufacturing Market, Achieve SunShot Goal

SUNPATH Program Will Boost American Competitiveness, Lower Cost of Solar Energy

August 02, 2011

U.S. Energy Secretary Steven Chu today announced a $50 million investment over two years for the SUNPATH program, aimed to help the nation reclaim its competitive edge in solar manufacturing. SUNPATH, which stands for Scaling Up Nascent PV At Home, represents the second solar Photovoltaic Manufacturing Initiative (PVMI) supporting the Department of Energy's SunShot Initiative.

"This investment provides a necessary boost to domestic solar manufacturing businesses, encouraging them to keep jobs here and establish America's leadership in the world's growing clean energy economy," said Secretary Chu. "In addition to invigorating clean energy manufacturing, this program will help achieve the SunShot goal of making unsubsidized utility-scale solar cost-competitive with other forms of energy by the end of the decade."

As recently as 1995, the United States maintained a dominant global solar market share, manufacturing 43% of the world's PV panels. In steady decline, U.S. market share shrank to 27% by 2000 and to 7% by 2010. SUNPATH will help return the United States to the forefront, driving innovation and assuring continued leadership in the 21st century clean energy economy.

PVMI Part II: SUNPATH seeks to increase domestic manufacturing through investments that have sustainable, competitive cost and performance advantages. SUNPATH will help companies with pilot-scale commercial production scale up their manufacturing capabilities, enabling them to overcome a funding gap that often curtails domestic business at a critical stage. By bridging this gap, SUNPATH will help ensure that innovative, low-cost solar technologies are manufactured in the United States.

The PV Manufacturing Initiative accelerates the cost reduction and commercialization of solar technologies by coordinating solutions across industry. The initiative will help create a robust, domestic PV manufacturing base and develop a workforce with the critical skills required to deliver reliable, affordable, clean energy.

PVMI Part I: Advanced Manufacturing Partnerships has resulted in the selection of $110 million in projects to three industry and academic consortia to enable substantial cost reductions in PV module production. To ensure that these technologies are manufactured domestically, PVMI Part II: SUNPATH will support an initial ramp up to high volume manufacturing. DOE's national laboratories are stepping up their validation facilities to ensure that the technologies developed and manufactured in Parts I and II are tested at scale in multiple locations and climates in the United States.

The Department of Energy is seeking applicants with industrial-scale demonstrations of PV modules, cells, or substrates that offer lower-cost solutions in line with the SunShot goal. Applications are due by October 28, 2011. More information and application requirements can be found at the Funding Opportunity Exchange (FOA number DE-FOA-0000566).

July 21, 2011

U.S. Energy Secretary Steven Chu today announced 31 tribal energy projects to receive $6.3 million over two years as part of the U.S. Department of Energy's ongoing efforts to support tribal energy development and continue strengthening the partnership with Tribal Nations. These competitively selected projects will allow Native American Tribes to advance clean energy within their communities by developing strategic energy plans, expanding the skills and knowledge of tribal members, and improving the energy efficiency of their buildings. These investments will help tribal communities to save money and reduce energy waste, expand the use of clean energy technologies, and promote economic development.

"Tribal Nations are well-positioned to take advantage of the benefits of clean energy and energy efficient technologies," said Secretary Chu. "Projects such as these will save energy and money, create long-term clean energy jobs, and spur economic development in tribal communities nationwide."
The more than $6 million in DOE funding will go toward 31 projects selected for negotiation of award in three project areas including over $2.1 million for energy efficiency feasibility studies, over $2.1 million for first-steps projects, and over $2 million for energy efficiency installation projects on tribal lands. DOE announced the availability of funding for these tribal energy projects in January. Another group of projects to receive funding for development and deployment of tribal renewable energy projects will be announced later this summer.

The awards cover the following areas:

$2.17 Million for Feasibility Studies – Nine Tribal projects will receive $2.17 million to improve the energy efficiency of their buildings. By conducting energy assessments to identify cost-effective building upgrades, recipients can develop plans to realize significant savings on their energy bills. When completed, the upgrades identified in the energy assessments could reduce energy use by at least 30 percent in each building.

$2.14 Million for First Steps Planning – Seventeen Tribal energy projects will receive $2.14 million for strategic planning, energy options analysis, energy organization development, and workforce development as the first steps toward a clean energy future. Several of the awardees will develop tribal strategic energy plans, enabling them to evaluate their current energy use and indigenous energy resources. Some of the projects also support the development of tribal energy organizations like utilities, energy offices, tribal committees, or other organizations to implement the selected Tribe's long-term energy plans and create opportunities for the deployment of clean energy projects. Others projects will help Tribes to explore development and deployment options for energy efficient and renewable technologies. Workforce development projects will provide clean energy training and workshops to tribal staff, leaders, and members, and train and certify tribal members to conduct energy assessments.

$2 Million for Installation Projects – Five projects on tribal lands will receive $2 million for the installation of energy efficient upgrades in their buildings that will help Tribes reduce electricity or heating and cooling costs by 30% or more.

Solar Research Earns Three Prestigious R&D 100 Awards

June 22, 2011

A technique to turn silicon into ink, a faster way to assess solar cells, and a better furnace for heating solar cells – all developed at the U.S. Department of Energy’s (DOE) National Renewable Energy Laboratory – have been named among this year’s most significant innovations by R&D Magazine.
The three prestigious awards bring to 50 the number of R&D 100 awards that NREL has won since 1982.

The three NREL winners all originated in basic technology research and now are on the brink of making huge differences in the marketplace.

Energy Secretary Steven Chu noted that 36 of the 100 awards were given for research in the nation’s federal labs and facilities. "The cutting-edge research and development done in our national labs (and sites) is helping to meet our energy challenges, strengthen our national security and enhance our economic competitiveness. It is gratifying to see their work recognized once again.”

Turning silicon into ink saves money, improves quality


NREL scientists led by Photovoltaic Incubator Subcontract Technical Monitor Richard Mitchell teamed with Innovalight, Inc. to invent silicon Ink, a liquid form of silicon, and develop it for use in solar cells.

This marks the first time that silicon has been sold in the marketplace as a liquid. With the Innovalight Silicon Ink process , a screen printer is added to the manufacturing line, which produces an immediate increase in solar cell efficiency by allowing lighter doping thus enhancing response to the blue portion of the spectrum.

The new product boosts the bottom line of a typical solar production plant by 20 percent, which for an average-size factory is $100 million, while boosting the efficiency of the cells by about 6 percent.

Faster assessment of solar-cell quality

NREL scientists teamed with Tau Science Corporation to develop “Flash Quantum Efficiency System for Solar Cells,” a way to assess the quality of solar cells at a speed that is about 1,000 times faster than previous methods.

The instrument – Tau markets it as FlashQE™ -- uses light-emitting diodes, high-speed electronics and mathematical algorithms to measure the quantum efficiency of solar cells orders of magnitude faster than before. What used to take 20 minutes – and therefore could be done only with random samples of cells – now can be done in a second, said NREL Senior Scientist David Young.

That means every single cell on a manufacturing line can be assessed and provide much needed process feedback information to the line and each cell can be sorted by its spectral response. Cells that respond best to, say, red light can be connected together to form a solar module. That way, a mismatched blue-response cell on a module won’t put the brakes on all the work the red-response cells are doing. And that means more efficient conversion of photons into electricity at sunrise and sunset when the red wavelengths predominate.

NREL’s Optical Cavity Furnace bolsters efficiency, lowers cost

The NREL Optical Cavity Furnace could revolutionize the solar cell manufacturing industry in the U.S. by producing higher quality and higher efficiency solar cells at a fraction of the cost of conventional, thermal ovens. The new furnace, which uses photons to uniformly heat crystalline solar cells and semiconductor materials, has increased the efficiency of the cells by 3 to 4 percent, said NREL Principal Scientist Bhushan Sopori. And it costs 75 percent less than an industrial thermal or infrared furnace.

The Optical Cavity Furnace, licensed to AOS Solar Inc., uses light enclosed within a highly reflective chamber to achieve a level of temperature uniformity that is impossible with other furnaces. It virtually eliminates energy loss by lining the cavity walls with ceramic materials of high reflectance and high thermal insulation, and by using an optimal geometric design.

AOS Solar manufactured the furnace, which the company branded as the Optical Processing Furnace, and it is operating at NREL’s Process Development Integration Lab, noted AOS CEO Anikara Rangappan.

"The awards demonstrate how NREL research produces market relevant results. These investments create American jobs while at the same time advancing our goals toward a clean energy future," NREL Director Dan Arvizu said.

49th year of Awards for Innovation

A full list of this year’s winners is available at www.rdmag.com.

The winners represent a cross-section of industry, academia, private research firms, and government labs, according to a statement by the magazine’s editors. Winning technologies are used in medical, industrial, research, consumer, and manufacturing applications.
Since 1963, the R&D 100 Awards have identified revolutionary technologies newly introduced to the market. Many of these have become household names, helping shape everyday life for many Americans.

Winners of the R&D 100 Awards are selected by an independent judging panel and the editors of R&D Magazine. The publication and its online portal serve research scientists, engineers, and other technical staff members at high tech industrial companies and public and private laboratories around the world.
Winners will be recognized at the R&D 100 Awards Banquet on Oct. 13 in Orlando, Fla.
NREL is the Department of Energy’s primary national laboratory for renewable energy and energy efficiency research and development. NREL is operated for DOE by The Alliance for Sustainable Energy, LLC.

DOE Offers $150 Million Conditional Commitment for a Loan Guarantee to Support Breakthrough Solar Manufacturing Process

Transformational Technology Could Cut Production Costs of Silicon Wafers in Half

Washington D.C. - U.S. Energy Secretary Steven Chu today announced the offer of a conditional commitment for a $150 million loan guarantee to 1366 Technologies, Inc. for the development of a multicrystalline wafer manufacturing project.  The project will be capable of producing approximately 700 to 1,000 megawatts (MW) of silicon-based wafers annually using a revolutionary manufacturing process called Direct Wafer.  The innovative process could reduce manufacturing costs of the wafers by approximately 50 percent, dramatically cutting the cost of solar power.  Phase 1 of the project will be located in Lexington, Massachusetts and is expected to generate 70 permanent jobs and 50 construction jobs.  The company is evaluating site locations for another planned phase, which they anticipate will create hundreds of additional jobs.

"This project is a game-changer that could dramatically lower the cost of photovoltaic solar cells.  It is exactly the kind of innovation that puts America at the forefront of the global clean energy race," said Secretary Chu.  "As global demand for solar cells increases, this kind of technology will help the U.S. increase its market share and be more competitive with other countries such as China, which currently accounts for 60 percent of the world supply of multicrystalline wafers."

The original development of the company's Direct Wafering technology was supported with a $4 million grant from DOE's Advanced Research Projects Agency - Energy program and a $3 million grant from DOE's Solar Energy Technology Program.  The innovative manufacturing process condenses four manufacturing steps into a single, low cost step and greatly reduces silicon waste by forming individual wafers directly from a pool of molten silicon.  A thin sheet of silicon freezes inside the Direct Wafer furnace and is then removed and laser-trimmed to size.  At full production, the entire wafer formation process is completed in just a fraction of the time relative to conventional batch processing which can take up to three days.  The company's revolutionary one-step process requires ninety percent less energy and results in an industry-standard product that can be used by any standard multicrystalline cell manufacturer.

The Department of Energy's Loan Programs Office administers three separate programs:  the Title XVII Section 1703 and Section 1705 loan guarantee programs, and the Advanced Technology Vehicle Manufacturing (ATVM) loan program.   The loan guarantee programs support the deployment of commercial technologies along with innovative technologies that avoid, reduce, or sequester greenhouse gas emissions, while ATVM supports the development of advanced vehicle technologies.  Under all three programs, DOE has issued loans, loan guarantees or offered conditional commitments for loan guarantees totaling over $33 billion to support 35 clean energy projects across the U.S.  DOE has also issued conditional commitments or loan guarantees to support numerous other projects, including four of the world's largest solar generation facilities, two geothermal projects, the world's largest wind farm and the nation's first new nuclear power plant in three decades.  For more information, please visit the Loan Programs Office.

DOE/HUD Announcement

DOE and HUD Announce Lenders to Participate in New Pilot Program to Help Homeowners Pay for Energy Improvements to their Homes

FHA PowerSaver Program to offer low-cost financing to credit-worthy
borrowers

April 21, 2011

Eighteen national, regional and local lenders will participate in a new two-year pilot program that will
offer qualified borrowers living in certain parts of the country low-cost loans to make energy-saving
improvements to their homes. Backed by the Federal Housing Administration (FHA), these new
PowerSaver loans will offer homeowners up to $25,000 to make energy-efficient improvements of
their choice, including the installation of insulation, duct sealing, replacement doors and windows,
HVAC systems, water heaters, solar panels, and geothermal systems.

U.S. Housing and Urban Development (HUD) Secretary Shaun Donovan and U.S. Department of
Energy Secretary Steven Chu announced the participating lenders (see attached list) during a tour of
a family-run company that offers home energy audits and upgrades in Long Island, New York.
"We believe the market is right for a low-cost financing option for families who want energy-saving
technologies in their home," said Secretary Donovan. "PowerSaver hits on all cylinders by helping
credit-worthy homeowners finance these upgrades, cut their energy bills and boost the local job
market in the process. While FHA and these lenders are jumpstarting this pilot, we hope its success
will lead to a growing private sector interest in making these types of loans."

Secretary Chu said, "Today, we are breaking down barriers and making energy efficiency more
accessible and more affordable. It’s the right thing to do for our environment, for our economy, and
for the pocketbooks of American families."

The remodeling industry cites surveys that point to a growing demand among homeowners interested
in making their homes energy efficient. Yet options are still limited for financing home energy
improvements, especially for the many homeowners who are unable to take out a home equity loan
or access an affordable consumer loan. Initially, the PowerSaver pilot program is estimated to assist
approximately 30,000 homeowners to finance energy-efficient upgrades though higher market demand
may increase this impact. According to HUD projections, more than 3,000 jobs will be created through
this pilot program and the impact may be larger if market demand for the loan program increases
over time.

Participating lenders are largely selected based on their commitment to work in partnership with
established home energy retrofit programs provided by states, cities, utilities, and home performance
contractors. These markets include, but are not limited to, areas of the country participating in the
Energy Department’s Better Buildings Program.

PowerSaver loans will be backed by the FHA but require these lenders to have significant "skin in the
game." FHA mortgage insurance will cover up to 90 % of the loan amount in the event of default.
Lenders will retain the remaining risk on each loan, incentivizing responsible underwriting and lending
standards.

PowerSaver has been carefully designed to meet a need in the marketplace for borrowers who have
the ability and motivation to take on modest additional debt to realize the savings over time from
home energy improvements. PowerSaver loans are only available to borrowers with good credit,
manageable debt and at least some equity in their home (maximum 100 % combined loan-to-value).
HUD developed PowerSaver as part of the Recovery Through Retrofit initiative launched in May 2009
by Vice President Biden’s Middle Class Task Force to develop federal actions that would expand
green job opportunities in the United States and boost energy savings by improving home energy
efficiency. The announcement is part of an interagency effort including 11 departments and agencies
and 6 White House offices.
