1. What is the Million Solar Roofs Initiative? Cauny Councu,
Million Solaz Roofs is an initiative to install solaz energy systems on one million U.S. buildings
by 2010. Il was announced by President Clinton on June 26, 1997 in his speech before the
United Nations Session on Environment and Development. This effort includes two types of
solaz technology photovoltaics that produce electricity from sunlight and solar thermal panels
that produce heat for domestic hot water, space heating or heating swimming pools.
The U.S. Department of Energy will work with partners in the building industry, other Federal
agencies, local and state governments, utilities, the solar energy industry, financial institutions
and non-governmental organizations to remove mazket barriers to solaz energy use and develop
and strengthen local demand for solaz energy products and applications. The Initiative will not
direct and control the activities at the state and community level nor will it typically pay for the
installation of solaz energy systems. Instead, the Million Solar Roofs Initiative will bring
together the capabilities of the Federal government with key national businesses and
organizations and focus them on building a strong market for solaz energy applications on
buildings.
The Million Solaz Roofs Initiative will:
• Reduce greenhouse gas and other emissions. In 2010, with one million solaz energy roofs
in place, the Initiative could reduce cazbon emissions in an amount equivalent to the annual
emissions from 850,000 cazs.
• Create high-tech jobs. By 2010, approximately 70,000 new jobs could be created as a result
of the increased demand for photovoltaic, solar hot water and related solaz energy systems.
• Keep the U.S. solar energy industry competitive. By increasing the domestic mazket for
solaz energy, increasing domestic production and reducing the unit cost for solaz energy
systems, the Initiative could enable U.S. companies to retain their competitive edge in the
worldwide mazket. By 2005, the photovoltaic mazket alone is expected to exceed $1.5 billion
worldwide.

2. Why are we undertaking this Initiative and at this time?
Greenhouse gas emissions aze caused mostly by the inefficient burning of fossil fuels. By
increasing the efficiency of how we use fossil fuels, reducing our use of these fuels and switching
to alternative, non-polluting fuels, we can significantly reduce the aznount of greenhouse gases
we put into the atmosphere and reduce the threat of global climate change. One of the most
promising non-fossil sources is solaz energy. As President Bill Clinton said in a June, 1997
speech to the United Nations, "Capturing the sun's warmth can help turn down the Earth's
temperature."
Photovoltaics were invented approximately 40 years ago at AT&T's Bell Laboratories and later
developed as a means to power satellites and space vehicles. As the U.S. investment in the
technology improved their performance and reduced their costs, other countries saw their
potential and stazted their own development efforts. In the past two decades, reseazch and
development have improved the efficiency and reliability of photovoltaics and reduced the costs
of photovoltaic electricity by a factor of 5.
The Million Solar Roofs Initiative will help increase the mazket for solaz energy and encourage
increased development and production of solar energy systems. At the same time, the Initiative
will give consumers an affordable, clean-energy option, create new U.S. high technology jobs
and play an important role in reducing greenhouse gas emissions.
3. What are the qualifications for a building to be a part of this Initiative?
To be included in the Million Solaz Roofs Initiative, a building's solaz energy system must
comply with all relevant parts of the National Electrical Code (NEC), Underwriters Laboratories
(UL) standards and the Solaz Rating and Certification Corporation (SRCC) standards, be located
on or immediately adjacent to the building and meet the following minimum standazds:
Photovoltaic Systems:
• Residential systems must be a minimum of 0.5 kW
• School or Church systems must be a minimum of 1.0 kW
• Commercial systems must be a minimum of 2.0 kW
Solar Thermal Water Heating Systems:
• Residential domestic must be a minimum of 1.0 kW equivalent or 20
squaze feet of collectors
• Residential swimming pool heating must be a minimum of 100 squaze feet
of collectors
• Commercial domestic must be a minimum of 2.0 kW or 40 squaze feet of
collectors
• Commercial swimming pool heating must be a minimum of 400 squaze
feet of collectors
Solar Thermal Space Heating Systems:
• Collector must be a minimum of 100 squaze feet or 4.0 kW
4. Who is a Million Solar Roofs Partner?
The Million Solar Roofs Initiative requires participation of all interested individuals, businesses,
industries, governments, federal agencies, utilities and non-governmental organizations. The
Initiative will work "bottom-up" attracting partners building by building, community by
community, state by state and business by business. It will also work "top-down" by developing
financing leveraging resources, coordinating Federal agency support and sharing information.
There are three types of partnerships:
? Individual Partnerships: Any person or organization who installs the minimum size
solar electric or solar thermal energy system on a residential, commercial, institutional or
government building will be able to register with the Million Solar Roofs Registry.
There is no requirement for participation in any other activities for these parties to be a
partner in the Initiative.
? State and Local Partnerships: Million Solaz Roofs State and Local Partnerships bring
together business, government and community organizations at the regional level with a
commitment to install solaz energy systems. Examples of State and Local Partners
include:
• Builders
• Energy Service Providers
• Utilities
• Non-Governmental Organizations
• Local Governments
• State Govenments
• Federal Government Agencies
? National Partnerships: At the national level, partners will make a commitment to install
a significant number of solaz energy systems and provide national support for the
Initiative. Examples of potential National Paztners include:
• Any Entity that commits to installing over 5,000 solar roofs by 2010
• Solar Energy Equipment Manufacturers and Distributors
• National Utility Companies and Energy Service Providers
• National Financial Institutions
• National Government Associations such as the National Association of Counties,
the National League of Cities, the National Association of State Energy Officials,
the U.S. Conference of Mayors and the International City/County Management
Association
• National Business Associations
• National Non-Governmental Organizations
5. What activities will State and Local Partnerships undertake?
Examples of activities that Million Solaz Roofs Paztnerships may undertake include:
• Developing a plan for solar energy installations under the Million Solaz Roofs Initiative.
• Committing to a specific number of solaz energy systems to be installed on buildings in
the period between 1998 and 2010.
• Committing government efforts to overcome barriers to solaz energy and energy
efficiency applications in buildings.
• Identifying financial incentives for solaz energy installations.

energy installers and utility personnel.
• Providing outreach support for solar energy and energy efficiency.
• Taking part in national information sharing, peer-to-peer exchanges and cooperative
reseazch and training efforts.
• Connecting the Million Solaz Roofs Initiative with other sustainable community
initiatives.
6. What assistance is available?
The Million Solaz Roofs Initiative, coordinated by the U.S. Department of Energy and supported
by its paztners, provide the following:
• Assistance in accessing low-cost loans, buy-down grants and other financial assistance.
• Training, technical assistance and information from DOE's Regional Support Offices and
the program staffs of DOE's Offices of Utility Technologies and Building Technology,
State and Community Programs, the DOE Federal Energy Management Program and the
DOE national laboratories.
• Recognition and support on a national, regional and local basis.
• Linkage with solaz energy businesses, associations and related industries that can provide
assistance to local teams and others interested in solaz energy applications.
7. What is the Federal commitment with its owu buildiugs?
The federal sector represents approximately 1/2% of the U.S. building inventory with its 500,000
buildings. These half-million buildings require the Federal government to spend over $3 billion
each yeaz for heating, cooling, lighting and powering the operations. During the past twenty
yeazs, actions have been taken to reduce that energy bill through energy efficiency investments
and the application of renewable, including solaz, energy systems on new and existing federal
buildings.
President Clinton has committed the Federal government to instaIl solaz electric and solar
thermal energy systems on 20,000 federal buildings by 2010. The U.S. Department of Energy's
Federal Energy Management Program will assist Federal agencies to meet that commitment.
The Federal Energy Management Program recently established umbrella contracts with energy
service companies to purchase energy efficiency services for Federal buildings. These "Super
Energy Savings Performance Contracts" enable all Federal agencies to improve the efficiency of
their buildings through cost effective partnerships with the private sector. The next round of
procurements will put in place almost $200 million in contracts which will use private financing
to install solaz energy systems at Federal facilities and enable Federal agencies to support the
Million Solar Roofs Initiative. In addition, the General Services Administration has developed
and implemented streamlined procurement procedures for Federal agencies to obtain solar energy
systems. The Department of Defense has already installed many solar energy systems on its
buildings including, for example, solaz hot water systems on Navy housing and a solar space
heating system on an Army aviation maintenance facility.
8. What are Photovoltaics?
Photovoltaic devices, or solaz cells, convert sunlight directly to electricity. It is an attractive
alternative to conventional sources of electricity for many reasons: it is silent, non-polluting, and
renewable; it requires no special training to operate; it is modulaz and versatile; it is extremely
reliable and virtually maintenance free (with no moving parts); and, it can be installed almost
anywhere. The customer pays only for the system; the fuel is free.
Photovoltaic cells aze made of a semiconductor material, usually silicon, and produce an electric
current in the presence of light. Individual cells are combined to create modules that produce a
specific amount of peak power. The modules, in tum, can be combined to create arrays that
produce larger amounts of power. These azrays can be sized to meet the power requirements of
the particular application.
9. What is Solar Thermal heating?
Solaz energy can be used to heat both water and air. Solar water heaters use the sun to heat either
water or aheat-transfer fluid, such as an antifreeze mixture, in collectors usually mounted on the
roof. The hot water, produced directly in the collector or via heat from the traz~sfer fluid, is then
stored in a standazd insulated water tank. Some systems use an electric pump to circulate the
fluid through the collectors. These environmentally friendly systems aze increasingly cost
competitive for providing domestic hot water and for swimming pool heating.
Solar space heating offsets building heating loads by either heating recirculated building air or
preheating outside or ventilation air. For heating recirculated air, solaz energy panels aze
normally required to receive direct sunlight and provide air temperatures higher than the interior
temperature to be effective. The transpired collector, which uses a dark collection surface with
perforated metal plates to heat the air just behind the plate surface, is very effective in preheating
outside or ventilation air. One additional benefit of the transpired collector is that it can also
serve as a component of the building shell.
10. How much will solar energy systems cost?
A residential solaz hot water system may cost anywhere from $1,800 to $3,500 and compete
effectively with water heated by electricity that costs 8 cents per kWh or more. Solaz thermal
space heating is very effective in most areas of the country. For example, the cost of a 100
squaze foot transpired collector installation can range from $1,000 for retrofits on existing
buildings and $500 - $700 for new systems, but can produce energy savings to offset the entire
cost of the system in five years or less.
Photovoltaic costs aze more complicated because system size, features and net cost to the users
depend on the financing terms and interest rates, available incentives and access to low cost
hazdwaze and installation through bulk purchasing programs. For example, residential
photovoltaic systems recently installed in Sacramento, California cost just under $7,000 per
kilowatt, and provide energy at approximately 24 cents per kilowatt-hour. Customers voluntarily
contribute $4 per month for these systems that aze owned by SMUD and provide power directly
to the utility grid. Participation is based on the customer's interest in supporting photovoltaics
and non-polluting energy production.
Solar technologies aze cost-effective in many niche applications today, for example, the use of
photovoltaics at remote installations not on the power grid. A solaz energy system's cost can
also be reduced by Federal, state and local tax incentives and other financial support. Additional
cost reductions aze possible through the use ofstate-implemented net metering options.
Financing assistance can, in many cases, reduce the cost of solaz energy systems to the point
where monthly payments for the system are less than the monthly energy bill savings.

Million Solar Roofs
State and Local Partnerships
What is a State and Local Partnership. The Million Solar Roofs Initiative is designed to support states and local
communities as they develop a strong commitment to the sustained deployment of solar energy technologies. In
order to insure positive and productive results, the Million Solar Roofs resources are focused on those areas which
have formed strong state or local partnerships which serve as the focal point for solaz activity in that azea. Million
Solar Roojs State and Local Partnerships are collaborative ventures that bring together business, government, the
energy industry and community organizations each individual entity being recognized as a member and partner
with acommitment to install a set number of solar energy systems. Examples of state and local parhiers who could
participate in a State and Local Partrtership include the following:
• Builders
• Energy service providers
• Utilities
• Non-governmental organizations
• Local governments
• State governments
Becoming a State and Local Partnership. To become a Million Solar Roofs State and Local Parhtership, any state
or local entity, on behalf of a specific Partnership, must send a letter to the Million Solar Roofs Coordinator,
expressing their commitment to the Initiative's objectives, describing the general nature of the partnership and its
membership and indicating thew goal for the specific number of qualified solar energy systems to be installed on
buildings in their community by 2010. At a minimum, partnerships must commit to installing S00 solar energy
systems by 2010.
In addition, Partnerships are asked to develop a drafr plan for meeting their installation goals under the Initiative.
Partnerships are encouraged to base their plans for deployment on local values in relation to the technologies'
unique applications and operational attributes. Examples of activities the Million Solar Roofs State and Community
Partnerships may undertake as part of their plan include the following:
• Committing state and local government actions to overcome barriers to solar energy and energy efficiency
applications in buildings;
• Identifying fmancial incentives for solaz energy installations;
• Establishing net metering for photovoltaics;
• Developing and/or modifying codes and standazds that affect solar energy installations;
• Implementing training programs for building officials, the construction industry, solar energy system
installers, and utility personnel;
• Providing outreach support for solar energy and energy efficiency;
• Taking part in national infomration sharing, peer-to-peer exchanges, and cooperative research and training
projects;
• Connecting the Million Solaz Roofs Initiative with other sustainable community initiatives.
Partnership Support. In return for their commitment, the Departittent of Energy, through its network of Regional
Support Offices will coordinate and provide support for the State and Local Partnerships in their area. This might
include the following:
• Access to the Million Solar Roofs Small Grants program for State and Local Partnerships;
• Assistance in accessing low-cost loans, buy-down grants, and other fmancial assistance;
• Training, technical assistance, and information from DOE's Regional Support Offices; the program staffs
