(3) Designing and demonstrating mass manu-
facturing capability to reduce costs of modular 
standardized solar-powered distributed air condi-
tioning systems and components. 
(4) Improving the efficiency of solar-powered 
distributed air-conditioning to increase the effective-
ness of solar-powered absorption chillers, solar-driv-
en compressors and condensors, and cost-effective 
precooling approaches. 
(5) Researching and comparing performance of 
solar-powered distributed air conditioning systems in 
different regions of the country, including potential 
integration with other onsite systems, such as solar, 
biogas, geothermal heat pumps, and propane assist 
or combined propane fuel cells, with a goal to de-
velop site-specific energy production and manage-
ment systems that ease fuel and peak utility loading. 
(c) COST SHARING.—The non-Federal share of re-
search and development projects supported under this sec-
tion shall be not less than 20 percent, and for demonstra-
tion projects shall be not less than 50 percent. 
(d) AUTHORIZATION
OF APPROPRIATIONS.—There 
are authorized to be appropriated to the Secretary for car-
rying out this section $2,500,000 for each of the fiscal 
years 2008 through 2012.

SEC. 4308. PHOTOVOLTAIC DEMONSTRATION PROGRAM. 
(a) IN GENERAL.—The Secretary shall establish a 
program of grants to States to demonstrate advanced pho-
tovoltaic technology. 
(b) 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 (f). 
(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 (f) 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.—Each State sub-
mitting a qualifying proposal 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 qualifying proposals in the 
time and manner specified by the Secretary shall be
162 
distributed pro rata to the States that have sub-
mitted qualifying proposals in the specified time and 
manner. 
(c) COMPETITION.—If more than $25,000,000 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 (b)(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. 
(d) 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. 
(e) COMPETITIVE CRITERIA.—In awarding funds in 
a competitive allocation under subsection (c), 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 amount of photovoltaics 
demonstrated;
163 
(B) maximize the proportion of non-Fed-
eral cost share; and 
(C) limit State administrative costs. 
(f) 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) endeavor to fund recipients in the commer-
cial, industrial, institutional, governmental, and resi-
dential sectors; 
(3) limit State administrative costs to no more 
than 10 percent of the grant; 
(4) report annually to the Secretary on— 
(A) the amount of funds disbursed; 
(B) the amount of photovoltaics purchased; 
and 
(C) the results of the monitoring under 
paragraph (5); 
(5) provide for measurement and verification of 
the output of a representative sample of the
