SEC. 507. PHOTOVOLTAIC DEMONSTRATION PROGRAM. 
(a) SHORT TITLE.—This section may be cited as the 
‘‘Solar Utilization Now Demonstration Act of 2007’’ or 
the ‘‘SUN Act of 2007’’. 
(b) IN GENERAL.—The Secretary of Energy shall es-
tablish a program of grants to States to demonstrate ad-
vanced photovoltaic technology. 
(c) REQUIREMENTS.— 
(1) ABILITY TO MEET REQUIREMENTS.—To re-
ceive funding under the program under this section, 
a State must submit a proposal that demonstrates, 
to the satisfaction of the Secretary, that the State 
will meet the requirements of subsection (g). 
(2) COMPLIANCE WITH REQUIREMENTS.—If a 
State has received funding under this section for the 
preceding year, the State must demonstrate, to the 
satisfaction of the Secretary, that it complied with 
the requirements of subsection (g) in carrying out 
the program during that preceding year, and that it 
will do so in the future, before it can receive further 
funding under this section.

(3) FUNDING
ALLOCATION.—Except as pro-
vided in subsection (d), each State submitting a pro-
posal that meets the requirements under subsection 
(c) shall receive funding under the program based on 
the proportion of United States population in the 
State according to the 2000 census. In each fiscal 
year, the portion of funds attributable under this 
paragraph to States that have not submitted pro-
posals that meet the requirements under subsection 
(c) in the time and manner specified by the Sec-
retary shall be distributed pro rata to the States 
that have submitted proposals that meet the require-
ments under subsection (c) in the specified time and 
manner. 
(d) COMPETITION.—If more than $80,000,000 is 
available for the program under this section for any fiscal 
year, the Secretary shall allocate 75 percent of the total 
amount of funds available according to subsection (c)(3), 
and shall award the remaining 25 percent on a competitive 
basis to the States with the proposals the Secretary con-
siders most likely to encourage the widespread adoption 
of photovoltaic technologies. In awarding funds under this 
subsection, the Secretary may give preference to proposals 
that would demonstrate the use of newer materials or 
technologies.

(e) PROPOSALS.—Not later than 6 months after the 
date of enactment of this Act, and in each subsequent fis-
cal year for the life of the program, the Secretary shall 
solicit proposals from the States to participate in the pro-
gram under this section. 
(f) COMPETITIVE CRITERIA.—In awarding funds in 
a competitive allocation under subsection (d), the Sec-
retary shall consider— 
(1) the likelihood of a proposal to encourage the 
demonstration of, or lower the costs of, advanced 
photovoltaic technologies; and 
(2) the extent to which a proposal is likely to— 
(A) maximize the size of photovoltaic in-
stallation, based on rated capacity; 
(B) maximize the proportion of non-Fed-
eral cost share; and 
(C) limit State administrative costs. 
(g) STATE PROGRAM.—A program operated by a 
State with funding under this section shall provide com-
petitive awards for the demonstration of advanced photo-
voltaic technologies. Each State program shall— 
(1) require a contribution of at least 60 percent 
per award from non-Federal sources, which may in-
clude any combination of State, local, and private

funds, except that at least 10 percent of the funding 
must be supplied by the State; 
(2) limit awards for any single project to a 
maximum of $5,000,000; 
(3) prohibit any nongovernmental recipient 
from receiving more than $1,000,000 per year; 
(4) endeavor to fund recipients in the commer-
cial, industrial, institutional, governmental, and resi-
dential sectors; 
(5) limit State administrative costs to no more 
than 10 percent of the grant; 
(6) report annually to the Secretary on— 
(A) the amount of funds disbursed; 
(B) the rated capacity of the photovoltaics 
purchased and installed; and 
(C) the results of the monitoring under 
paragraph (7); 
(7) provide for measurement and verification of 
the output of a representative sample of the 
photovoltaics systems demonstrated throughout the 
average working life of the systems, or at least 20 
years; 
(8) require that applicant buildings must have 
received an independent energy efficiency audit dur-
