SECTION 1. SHORT TITLE.

This Act may be cited as the ''10 Million-Solar Roofs Act of
2008''.

SEC. 2. FINDINGS.

Congress finds that--
(1)(A) there is huge potential for increasing the quantity
of electricity produced in the United States from distributed
solar photovoltaics; and
(B) the use of photovoltaics on the roofs of 10 percent of
existing buildings could meet 70 percent of peak electric
demand;
(2) investment in solar photovoltaics technology will
create economies of scale that will allow the technology to
deliver electricity at prices that are competitive with
electricity from fossil fuels;
(3) electricity produced from distributed solar
photovoltaics helps to reduce greenhouse gas emissions and does
not emit harmful air pollutants, such as mercury, sulfur
dioxide, and nitrogen oxides;
(4) electricity produced from distributed solar
photovoltaics enhances national energy security;
(5) investments in renewable energy stimulate the
development of green jobs that provide substantial economic
benefits;
(6)(A) rebate programs in several States have been
successful in increasing the quantity of solar energy from
distributed photovoltaics;
(B) the State of California has used rebate programs to
install nearly 300 megawatts of grid-connected photovoltaics
since 2000; and
(C) the State of New Jersey has installed nearly 50
megawatts of grid-connected photovoltaics since 2001, including
20 megawatts in 2007 alone; and
(7) Germany has installed nearly 4,000 megawatts of
distributed solar photovoltaics and sustained an annual growth
rate approaching 67 percent since enacting aggressive laws to
encourage photovoltaic installations

SEC. 3. REBATES FOR PURCHASE AND INSTALLATION OF PHOTOVOLTAIC SYSTEMS.

(a) In General.--The Secretary of Energy (referred to in this Act
as the ''Secretary'') shall establish a program under which the
Secretary shall provide rebates to eligible individuals or entities for
the purchase and installation of photovoltaic systems for residential
and commercial properties in order to install, over the 10-year period
beginning on the date of enactment of this Act, at least an additional
10,000,000 solar systems in the United States (as compared to the
number of solar systems installed in the United States as of the date
of enactment of this Act) with a cumulative capacity of at least 30,000
megawatts.
(b) Eligibility.--
(1) In general.--To be eligible for a rebate under this
section--
(A) the recipient of the rebate shall be a
homeowner, business, nonprofit entity, or State or
local government that purchased and installed a
photovoltaic system for a property located in the
United States;
(B) the total capacity of the photovoltaic system
for the property shall not exceed 4 megawatts;
(C) the buildings on the property for which the
photovoltaic system is installed shall--
(i) in the case of a new or renovated
building, achieve a rating of not less than 75
under the Energy Star program established by
section 324A of the Energy Policy and
Conservation Act (42 U.S.C. 6294a) (or an
equivalent rating under an established
benchmarking metric); and
(ii) in the case of any building not
described in clause (i), be retrofitted to
achieve a rating improvement of not less than
30 points under the Energy Star program (or an
equivalent improvement under an established
benchmarking metric); and
(D) the recipient of the rebate shall meet such
other eligibility criteria as are determined to be
appropriate by the Secretary.
(2) Other entities.--After public review and comment, the
Secretary may identify other individuals or entities located in
the United States that qualify for a rebate under this section.
(c) Amount.--
(1) In general.--Subject to paragraph (2), the amount of a
rebate provided to an eligible individual or entity for the
purchase and installation of a photovoltaic system for a
property under this section shall be at least $3 for each watt
of installed capacity.
(2) Maximum amount.--The total amount of a rebate provided
to an eligible individual or entity for the purchase and
installation of a photovoltaic system for a property under this
section shall not exceed 50 percent of the cost of the purchase
and installation of the system.
(d) Relationship to Other Law.--The authority provided under this
section shall be in addition to any other authority under which credits
or other types of financial assistance are provided for installation of
a photovoltaic system for a property.
(e) Authorization of Appropriations.--There are authorized to be
appropriated such sums as are necessary to carry out this section.
10 Million-Solar Roofs Act of 2008 - Requires the Secretary of Energy to establish a program to provide rebates (for each watt of installed capacity) to eligible individuals or entities for the purchase and installation of photovoltaic systems, over a 10-year period, of at least an additional 10 million solar systems in the United States with a cumulative capacity of at least 30,000 megawatts.

Provides eligibility requirements for homeowners, businesses, nonprofit entities, and state and local governments. Sets minimum Energy Star or equivalent ratings that must be achieved by the buildings for which the photovoltaic system is installed.

Limits the total amount of a rebate to 50 percent of the purchase and installation cost of the system.
