Note: The reported system price for the residential market is representative of the median price reported for systems less than or equal to 10 kW in size. The modeled

residential system price represents a ~5 kW system. The reported system price for the commercial market is representative of the median price reported for systems

greater than 100 kW in size. The modeled commercial system price represents a ~220 kW rooftop system. The reported system price for the utility-scale market

represents the capacity-weighted average reported price for ground-mounted systems greater than 2 MW in size, with an average project size of 16.4 MW. The

modeled system price of utility-scale systems represents a ~190 MW fixed-tilt ground-mounted system. Bottom-up system prices are representative of bids by an

installer in the fourth quarter of the previous year. The Global Module Price Index is the average module selling price for the first buyer (P Mints SPV Market Research).

Near Future Price Trends Conclusion


7/29

Derived from project-level data reported for residential, commercial, and

utility-scale PV systems installed through year-end 2012, with a limited set ofresults presented for the first half of 2013

Distributed PV: 47 PV incentive programs spanning 24 states provided project-

level installed price data for PV systems funded through current and previous

programs

Utility-scale PV: Data sourced from Section 1603 Grant Program, FERC Form

1, SEC filings, company presentations, trade press articles

All projects for which the reported installed price was deemed likely to

represent an appraised valuerather than an actual transaction price were

eliminated from the data sample

Final cleaned data sample consists of >200,000 PV systems totaling 4.7 GW of

installed capacity; represents approximately 65% of all grid-connected PV

capacity installed in the United States through 2012 and about 50% of all 2012

capacity additions.

Data from the California Solar Initiative (CSI) program show that installed prices have

continued to fall into 2013

Median installed prices in CSI fell by roughly $0.53-0.77/W (10-15%) during the first half

of 2013, relative to 2012, across the three size ranges shown.

Variation in Installed Price by System Size:Residential and Commercial PV Systems in 2012

10

Installed prices exhibit clear economies of scale, with the median installed price for the

largest commercial systems 38% lower than for the smallest residential systems (and

lower installed prices for utility-scale PV, as shown on later slides)

Scale economies are especially pronounced at the small end of the size spectrum

Substantial variability in installed prices exists within each size range, reflecting regional,

local, project/site-specific, and installer-specific drivers.

Variation in Installed Price by State:Residential and Small Commercial (10 kW) PV in 2012

11

The median installed price differs by roughly $2.0/W between the lowest- and highest-

priced states, though similar variability also exists withinindividual states

California, a relatively high cost state, pulls the overall sample median upward

Installed price differentials across states reflect a wide array of potential factors: market

size and maturity, incentive levels, regulatory costs, sales tax, and others.

Note: Numbers in parentheses below each state indicate the number of observations; median installed prices are shown only if 15 or more observations are available

for a given state. CO and MN data are based on aggregated statistics provided the PV program administrator rather than project-level data.

Variation in Installed Price by State:Large Commercial (>100 kW) PV Systems in 2012

12

A large disparity in median installed price ($2.9/W) between the lowest- and highest-

priced states also exists among large commercial systems (though some caution is

warranted, given small sample sizes)

Partly reflects differences across states in customer segments (e.g., roughly 2/3rdsof CA

Installed Price Data for Utility-Scale PV:Important Notes and Caveats

13

Utility-scale PV is defined as ground-mounted systems 2 MW, regardless of

whether electricity is delivered to utility or customer

Analysis considers only entire projects (not individual phases)

Project sample consists of 191 fully operational projects installed through year-

end 2012, totaling roughly 1,600 MW (~70% of U.S. total)

A few important caveats:

Small sample size that includes many 2-10 MW systems as well as a number

of larger one-off projects with atypical characteristics

Lag in component pricing and market conditions between the time that a

project was contracted and when it was installed

Data reliability is somewhat mixed depending on the data source availablefor any individual project

Focus is on installed price rather than levelized cost of electricity, and thus

ignores performance differences across system configurations.


14/29

Installed Price of Utility-Scale PV Projects

Over Time

14

Capacity-weighted average installed price was $3.35/W for crystalline, fixed-tilt projects

installed in 2012, down from $3.59/W in 2011, a 7% declineYoY

Capacity-weighted average installed price was $3.60/W for crystalline tracking systems

and $3.23/W for thin-film, fixed-tilt systems completed in 2012

A wide distribution in installed prices is observed, partially reflecting variation in system

size (shown on following slide) and other project characteristics.

Variation in Installed Price of 2012 Utility-

Scale PV Projects by Size and Configuration

15

Larger (>10 MW) utility-scale systems vary in price within a relatively narrow range

from roughly $2.50/W to $4.00/W, while smaller utility-scale projects span a muchbroader range that includes a number of high-priced systems (>$5/W)

Among the relatively small number of >10 MW systems, capacity-weighted average

prices were $3.08/W for crystalline, fixed-tilt; $3.56/W for crystalline with tracking; and

$3.14/W for thin-film, fixed tilt systems.

Near Future Price Trends

Conclusion


17/29

Detailed cost models for specific PV system designs account for all

materials, labor, overhead and profit, land acquisition and preparation costs,

and regulatory costs for a PV system up to the point of grid tie-in

Better able to determine individual components contributions to total

system cost

NREL cost models are compiled from numerous industry and primarysources, for each component of a system incurred by a manufacturer

and/or installer, and validated with manufacturers and installers

Dialogue created differentiates the interview method from the survey

method by allowing for greater specificity and feedback of results

The area of each modeled system is kept constant across years, but it

increases in capacity based on improved module efficiencies.

Capacity-Weighted Average (Utility-Scale) Prices vs. Q4 2011

Bottom-Up Benchmark Overnight Capital Cost

21

overnight capital cost = 5.1 kW; median commercial reported size (> 100 kW) = 258 kW; commercial

bottom-up benchmark overnight capital cost = 221 kW; cap.-weighted average ground-mounted system (2

MW) reported size= 16 MW; utility-scale bottom-up benchmark overnight cap. cost = 191.5 MW.

Note: Many factors contribute to the reported price and overnight capital cost differing values including the additional costs above and beyond

the overnight capital cost of a project, such as third-party financing; different system sizing; installation time lag; and various methods for

calculating system sales price. Error bars for reported price data represent 20/80 percentile of datasets. The costs includedin the bottom-up

benchmarks represent national averages; there is significant cost variation for each component, depending on the installer, market, or time frame.

The above data is representative of the following system sizing: median residential reported size= 5.1 kW; residential bottom-up benchmark

Reasons for Deviations Between Reported Price and

Bottom-Up Benchmark Overnight Capital Cost

22

Price vs. cost

Reported pricing reflects what a customer will pay for a system (i.e., what the marketwill bear). A customers purchase price may be significantly higher than it would be

elsewhere, regardless of the underlying cost to the installer, due to:

Higher electricity rates (e.g., CA)

Greater incentive programs (which may lower a customers upfront cash outlay,

though not the price paid to the installer)

Barriers to entry within specific markets, etc.

The bottom-up benchmarks are reflective of consistent, transparent assumptions of the

cost and representative margins of each subcomponent to an installer, regardless of

market conditions or incentives.

Timing

Reported pricing generally reflects module and other component pricing at the time

that installation contracts were signed (could precede installation date by more than a

year for large projects)


23/29

Bottom-up benchmark costs are contemporaneous with time subcomponent

pricing estimates. Q4 benchmarks are compared with the following year, but

may not fully capture lag between price quote and installation date.

Geographic location

Reported price is weighted heavily toward California and New Jersey

Bottom-up benchmark based on national averages.

Project specifics Projects within dataset of report pricing includes systems not currently

modeled in bottom-up benchmark, such as those using high-efficiency panels,

high proportion of government facilities, and relatively small utility-scale

projects.

Installed Price of Residential & Commercial PV Systems:U.S. Systems Installed in 2012 vs. German Systems Quoted in 2012

25

Installed prices in the United States are high compared to most other major

international PV markets, due largely to differences in soft costs

The disparity is particularly stark in comparison to Germany, where installed prices

are $2.61-2.68/W (51-56%) lower across the three size ranges shown (on a pre-

tax/VAT basis)

Suggestive of potential for near-term cost savings in the United States.

Module prices in 2012 continued recent trend of dramatic reductions

Since 2008 has fallen on average 35% per year

Mixed forecasts on future module ASP

However, not expected to increase or decrease dramatically in price

By 2014 ASP projected to be between $0.50/W - $0.75/W

Major system price reductions are not expected to come from PV module price alone,

as was the case in previous years.

Conclusion


29/29

Continued system price reductions in 2012; more expected in the near-term, despitetensions on trade issues

Reported system pricing fell 6-14% from 2011-2012

Modeled overnight capital costs fell 13-23% from Q4 2011 to Q4 2012.

Despite general downward trend, large variation in reported pricing within marketsegment in 2012

A difference of roughly $2/W in median installed price between the lowest- and

highest-priced states for residential & commercial systems 10 kW, but similarvariability also exists withinindividual states

Ground-mounted systems 2 MW ranged in price from $2/W to above $6/W.

Difference between reported price and bottom-up benchmark overnight capital cost forsimilarly segmented systems in 2012

Residential ($5.30/W reported price, $4.22/W bottom-up benchmark overnight

capital cost); commercial ($4.62/W reported price, $3.22/W bottom-up benchmarkovernight capital cost); utility-scale ($3.35/W reported price, $2.50/W bottom-upbenchmark overnight capital cost)

Delta between reported pricing and modeled cost is due to various factors, such asinefficient pricing, timing, geographic location, and project specifics.
