Introduction There exists a need for reliable and comprehensive information on PV system pricing. Differences between various attempts to estimate the cost and price of solar in the market; this briefing is designed to explain some of these variances Rapid market growth and changes to PV system pricing in recent years Policy support for PV deployment premised on stimulating cost reductions through market scale and development DOE SunShot Initiative seeks to reduce PV system prices 75% over the 2010-2020 period. This briefing provides a high-level overview of historical, recent, and projected near-term PV system pricing trends in the United States, drawing on several ongoing research activities at LBNL and NREL: LBNL s annual Tracking the Sun report series ( reported system prices ) NREL s bottom-up PV cost modeling ( modeled system prices ) NREL s synthesis of PV market data and projections. 3

Executive Summary Reported pricing for PV system installations completed in 2013, based in part on data reported to PV incentive programs: Residential and small commercial ( 10 kw) was $4.69 /W (median) Large commercial (>100 kw) was $3.89/W (median) Utility-scale ( 5 MW, ground-mounted) was $3.00/W (capacity weighted average). Modeled solar PV system prices, using industry validated tools, quoted in Q4 2012 (and expected to be installed in 2013): Residential (5 kw) was $3.71/W Commercial (223 kw) was $2.61/W Utility-scale (185 MW) was $1.92/W. Delta between reported and modeled pricing is due to various factors, such as market fundamentals (e.g., large fraction of data for reported prices is from CA and other high-priced markets), inefficient pricing (i.e., value-based pricing), project characteristics (e.g., high-efficiency panels with single-axis tracking), and long temporal lags between contract signing and installation for large utility-scale projects. Reported system prices of residential and commercial PV systems declined 6% 7% per year, on average, from 1998 2013, and by 12% 15% from 2012 2013, depending on system size. Market analysts expect system prices to continue to fall, but module prices to stabilize in near-term. Modeled system prices quoted in Q4 2013 (and expected to be installed in 2014): Residential (5 kw) was $3.29/W, a reduction of 12% from Q4 2012 Consistent with leading residential installers pricing, such as SolarCity s reported Q2 2014 costs ($3.03/W), plus a reasonable operating profit margin Commercial (200 kw) was $2.54/W, a reduction of 3% from Q4 2012 Utility-scale (185 MW) was $1.80/W, a reduction of 5% from Q4 2012. Note: All PV installed price data are reported in terms of real 2013 dollars per Watt-DC. 4

Note: The reported system price for the residential market is the median price reported for systems less than or equal to 10 kw. The modeled residential system price represents a ~5 kw system. The reported system price for the commercial market is the median price reported for commercial systems greater than 100 kw. The modeled commercial system price represents a ~200 kw rooftop system. The reported system price for the utility-scale market is the capacity-weighted average reported price for groundmounted systems greater than or equal to 5 MW in size, with a capacity-weighted average project size of 150 MW in 2013. The modeled system price of utility-scale systems represents a ~175 MW fixed-tilt ground-mounted system. Modeled system prices for all sectors are representative of bids issued 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). 5

Data Sources and Methodology for Reported Installed Prices Prices are derived from project-level data reported for PV systems installed through year-end 2013 (and from a more limited set of states for H1 2014) Data Sources Residential and commercial PV (<5 MW and/or roof-mounted): Project-level data obtained from 60 PV incentive programs, spanning 32 states Utility-scale PV (>5 MW ground-mounted): Sourced from FERC Form 1, Section 1603 Grant Program, SEC filings, company presentations, trade press articles Raw sample represents 80% of all grid-connected PV capacity installed in the United States through 2013 and 78% of all 2013 capacity additions All residential and commercial projects for which reported prices were deemed likely to represent appraised values, rather than prices paid to the installer/epc, were removed from the final data sample used for analysis After removing these and other systems, the final data sample represents 71% of all grid-connected PV capacity installed in the United States through 2013 and 64% of all 2013 capacity additions. 7

The Global Module Price Index is SPV Market Research s average module selling price for the first buyer (P. Mints). Since 1998, reported PV system prices have fallen by 6-8% per year on average From 2012 to 2013, reported prices fell by $0.65/W (12%) for systems 10 kw and by $0.70/W (15%) for systems >100 kw By comparison, global annual average module prices rose by $0.07/W from 2012-2013. 2006 n=8,943 92 MW Installation Year Global Module Price Index 2007 n=12,764 132 MW 2008 n=13,686 238 MW Residential & Commercial PV (Median Values) 10 kw 2009 n=24,319 303 MW 2010 n=36,455 506 MW 10-100 kw >100 kw 2011 n=42,360 981 MW 2012 n=51,753 1174 MW 2013 n=50,614 1098 MW 8

Preliminary Price Trends for Systems Installed in H1 2014 from a Subset of State Markets Installed Price (2013$/W DC ) $8 $6 $4 $2 $0 Residential & Commercial PV: AZ, CA, MA, MD, NJ, NY (Median Values) $4.74 $4.50 $4.36 $3.97 $3.99 $3.52 10 kw n=32,517 (2013) n=12,902 (H1 2014) 10-100 kw n=5,851 (2013) n=2,372 (H1 2014) 2013 2014 (H1) >100 kw 10 kw 10-100 kw >100 kw n=912 (2013) n=314 (H1 2014) Note: The 2013 and H1 2014 values in this figure are based on data from a smaller set of states than elsewhere in this section, and thus the 2013 values differ from the national median values cited previously. Installations in a number of the larger PV incentive programs and state markets have shown continued price declines into H1 2014 Median reported prices fell by roughly $0.24-0.48/W (5-12%) during the first half of 2014, relative to 2013, across the three size ranges shown. 9

Variation in Reported Price by System Size: Residential and Commercial PV Systems in 2013 Installed Price (2013$/W DC ) $8 $6 $4 $2 $0 $4.76 $4.83 $4.57 $4.30 $4.38 $4.24 $4.15 $3.80 $3.08 2 kw n=1,734 3 MW 2-5 kw n=15,590 59 MW 5-10 kw n=25,068 178 MW 10-30 kw n=6,191 85 MW 30-100 kw n=911 51 MW 100-250 kw n=503 83 MW Residential & Commercial PV Systems Installed in 2013 (Median and 20 th /80 th Percentiles) 250-500 kw n=264 93 MW 500-1000 kw n=157 103 MW >1000 kw n=196 442 MW System Size Range (kw DC ) Reported prices exhibit clear economies of scale, with the median price for the largest commercial systems 35% lower than for the smallest residential systems (and lower installed prices for utility-scale PV, as shown on later slides) Substantial variability in reported prices exists within each system size range, reflecting different regional drivers of pricing, which may include market and policy dynamics, project/site-specifics, and installer specifics. 10

Variation in Reported Price by State: Residential and Small Commercial ( 10 kw) PV in 2013 Installed Price (2013$/W DC ) $8 $7 $6 $5 $4 $3 $2 $1 $0 $3.33 Systems 10 kw DC Installed in 2013 (Median and 20 th /80 th Percentiles) FL 19 $3.47 TX 796 $3.48 ME 258 $3.71 DC 104 $3.83 NH 241 $3.85 UT 68 $3.95 NJ 3156 $3.99 CO 2330 $4.03 CT 626 $4.06 AZ 4633 $4.16 DE 20 Note: Numbers in parentheses below each state indicate the number of observations; installed price data are shown only if 15 or more observations are available for a given state. The median reported price differs by ~$2/W between the lowest- and highest-priced states, though similar variability also exists within many individual states Reported prices in California pull the overall sample median upwards Reported price differentials across states reflect a wide array of potential factors, including: market size and maturity, incentive levels, sales taxes, administrative costs, labor costs, and project characteristics. $4.19 NV 141 $4.44 PA 91 $4.45 MA 2697 $4.46 NM 833 State andsample Size $4.47 RI 24 $4.56 NY 1455 $4.66 MD 56 $4.71 VT 756 $4.75 OR 349 $4.79 WI 144 $4.94 CA 25273 $5.01 IL 146 $5.21 MN 60 $5.31 NC 480 11

Installed Price Data for Utility-scale PV: Important Notes and Caveats Utility-scale PV is defined as ground-mounted systems 5 MW, regardless of whether electricity is delivered to utility or customer Analysis considers only entire projects (not individual phases) Project sample consists of 100 fully operational projects installed through yearend 2013, totaling roughly 3,200 MW (88% of total U.S. utility-scale) A few important caveats: Significant and uncertain lags exist between when projects are contracted and installed (i.e., prices reported for projects installed in 2013 may reflect PPAs or EPC contracts signed in 2009-2012) Data reliability is mixed, depending on the data sources available for any individual project, with possible inconsistencies in the scope of cost components captured Focus is on reported installed prices rather than levelized cost of electricity, and thus ignores performance differences across system configurations. 13

Reported Price of Utility-scale PV Projects over Time Installed Price (2013$/W DC ) $10 $8 $6 $4 $2 $0 Utility-Scale PV Crystalline, Fixed-Tilt Crystalline, Tracking Thin-Film, Fixed-Tilt Thin-Film, Tracking CPV, Tracking Cap-Wtd. Averages 2007-2009 2010 2011 2012 2013 n=5 (88 MW) n=10 (204 MW) n=26 (482 MW) n=34 (1019 MW) n=25 (1441 MW) Installation Year Prices have declined over time, but little movement between projects installed in 2012 and 2013 Capacity-weighted average prices were $2.97/W for crystalline, fixed-tilt; $3.12/W for crystalline with tracking; and $2.72/W for thin-film, fixed-tilt systems completed in 2013 Majority of 2013 systems fall within a range of roughly $2.60/W to $3.20/W Wide price distribution within each system type reflects variation in system size, other project characteristics, market and policy conditions, and contracting date (e.g., outlying 2013 project, LADWP Pine Tree Solar Project, was contracted in 2010). 14

Methodology for Bottom-up Modeling Detailed system pricing models for specific PV system designs were developed in collaboration with industry and 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 price Input data for NREL models are compiled from numerous industry and primary sources, for each component of a system incurred by a manufacturer and/or installer, and validated with manufacturers and installers (more detail on this methodology can be found in Goodrich et al. 2012) Dialogue created differentiates the interview method from the survey method by allowing for greater specificity and feedback of results Modeled prices represent installer bid or quoted prices for the time periods noted Modeled system sizes are similar for each market segment, and are described below the figures. 16

Bottom-up Modeled System Price of PV Systems by Sector, Q4 09 - Q4 13 2013$/W DC $8 $7 $6 $5 $4 $3 $2 $6.91 $6.06 $4.28 $3.74 $3.29 $5.11 $4.74 $3.26 $2.65 $2.54 $4.36 $3.74 $2.54 BOS Inverter Module $1.94 $1.80 $1 $0 Q4 2009 Q4 2010 Q4 2011 Q4 2012 Q4 2013 Q4 2009 Q4 2010 Q4 2011 Q4 2012 Q4 2013 Q4 2009 Q4 2010 Q4 2011 Q4 2012 Q4 2013 Residential Commercial Utility ground mount (Fixed axis) Since Q4 2009, modeled system prices fell between 16% 19% per year 1/2-2/3 of reduction attributed to module price reductions From Q4 12 to Q4 13, modeled system prices fell between $0.07/W - $0.44/W, or 3-12% Q4 2013 bottom-up modeled residential system price of $3.29/W is consistent with leading residential installers pricing, such as SolarCity s reported Q2 2014 costs ($3.03/W), plus a reasonable operating profit margin. Note: Standard crystalline silicon modules (13.5% efficiency in Q4 2009 to 15.0% in Q4 2013). System sizes: residential: 5 kw in Q4 2009 through Q4 2013; commercial: 202 kw in Q4 2009 to 223 kw in Q4 2012 (200 kw in Q4 2013); utility-scale: 175 MW in Q4 2009 to 185 MW to Q4 2013). Modeled system sizes in the residential and commercial rooftop sectors were chosen based on typical system sizes, then adjusted for optimal inverter configuration. System sizing for utility-scale benchmarks were chosen for comparison purposes against pricing reported from DOE s Energy Information Administration (2010). Source: SolarCity. (2014).

2013 Reported Median (Residential/Commercial) and Capacity-weighted Average (Utility-scale) Prices vs. Q4 2012 Bottom-up Benchmark (Quoted) Modeled Prices $7 $6 System Price (2013 $/W DC ) $5 $4 $3 $2 $1 $4.69 $3.47 $4.94 $3.74 $3.89 $2.65 $4.26 $2.65 $3.00 $1.95 $0 Median reported price - U.S. Median reported price - TX Median reported price - CA Modeled Price - U.S. Median reported price - U.S. Median reported price - CO Median reported price - CA Modeled Price - U.S. Cap. w. avg. reported price - U.S. Modeled Price - U.S. Residential Commercial Utility-Scale Grount- Mounted 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 included in 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= 5.6 kw; residential bottom-up benchmark overnight capital cost = 5 kw; median commercial reported size (> 100 kw) = 266 kw; commercial bottom-up benchmark overnight capital cost = 223 kw; cap.-weighted average ground-mounted system ( 5 MW) reported size= 149 MW; utility-scale bottom-up benchmark overnight cap. cost = 185 MW. 19

Reasons for Deviations Between Reported and Modeled Installed Prices Median reported U.S. distributed system pricing is weighted heavily towards California CA is generally a high-cost state with relatively high retail rates that may allow for higher installer margins Bottom-up benchmark overnight capital cost are more in line with states with lower reported median prices (e.g., TX) 2013 median reported TX residential system price = $3.47/W Q4 2012 modeled price for residential systems = $3.74/W Utility-scale projects duration between signature of electricity sales agreement and placed in service date can be significant Reported pricing generally reflects module and other component pricing at the time that electricity sales agreements (PPAs) were signed Time lags of up to 4 years exist between date of PPA signature and commercial operation for utility-scale projects installed in 2013 Bottom-up overnight capital costs represent pricing at the time of benchmark. 20

Reasons for Deviations Between Reported and Modeled Installed Prices (cont.) Large variety in projects currently built in the United States Lack of standards and transparency in incentive program reporting Large differences across system configurations for geographic, market, and LCOE purposes Bottom-up, modeled system prices represents a specific prototypical project Price and cost represent different things Reported pricing reflects what customers did pay for systems (i.e., what the market will bear). A customer s 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) Higher incentive levels (which may lower a customer s upfront cash outlay, though not the price paid to the installer) Lower levels of competition, consumer awareness, etc. The bottom-up benchmarks are reflective of consistent, transparent cost assumptions and representative margins of each subcomponent to an installer, regardless of market conditions or incentives. 21

Bottom-up Modeled Overnight Capital Cost of Utilityscale PV Systems by Size System Price (2013 $/W DC ) $3.5 $3.0 $2.5 $2.0 $1.5 $1.0 $3.16 $2.59 $2.80 $2.25 $2.03 $1.94 $2.65 $2.11 $1.88 $2.45 $1.92 Q4 2011 Q4 2012 Q4 2013 $1.80 $0.5 $0.0 5 MW 10 MW 20 MW 185 MW System Size Range (MW DC ) Economies of scale for utility-scale projects are illustrated in modeled system prices Depending on the year, prices decline by 14-27% from 5 MW to 185 MW Most of the price reduction (~70%) accompanies increasing size from 5 MW to 20 MW, with diminishing returns to scale beyond 20 MW. 22 Note: Standard crystalline silicon modules (14.9% efficiency in Q4 2011 and 15.0% in Q4 2012/3).

Variation in Reported Price of 2012-13 Utilityscale PV Projects by Size and Configuration Installed Price (2013$/W DC ) $6 $5 $4 $3 $2 $1 $0 Utility-Scale PV Installed in 2012 and 2013 Crystalline, Fixed-Tilt Crystalline, Tracking Thin-Film, Fixed-Tilt Thin-Film, Tracking CPV 0 50 100 150 200 250 300 System Size (MW DC ) Reported pricing for larger systems resides within narrower range than smaller systems, but economies of scale are obscured within this data to some extent by other countervailing drivers: Technology and location-specific issues (e.g., the 320 MW DC California Valley Solar Ranch project uses premium efficiency modules) Larger systems often have longer time lag between PPA execution and project completion and thus may portray an earlier pricing environment (e.g., 2-4 years earlier for some of the largest utility-scale systems). 23

Installed Prices for Residential PV: United States vs. Germany $5 Installed Price, Excluding Sales Tax/VAT (2013$/W DC ) $4 $3 $2 $1 $0 $4.40 $3.52 $3.29 $2.05 U.S. Reported Price (Installed in 2013) U.S. Modeled Price (Quoted Q4 2012) U.S. Modeled Price (Quoted Q4 2013) Germany Reported Price (Quoted in 2013) Note: The German data are based on price quotes for roughly 2,300 individual PV systems obtained by EuPD through its quarterly survey of German installers and provided to LBNL. Installed prices in the United States are high compared to many other major international PV markets; the disparity is particularly stark in comparison to Germany Hardware costs are fairly similar across countries; thus the gap in total installed prices must reflect differences in soft costs (including installer margins) Suggestive of a potential for near-term installed price reductions in the United States. 24

Conclusion Continued system price reductions in 2013; more expected in the near-term, despite U.S. tariffs on foreign PV modules Reported distributed system pricing fell 12-15% from 2012-2013 Modeled system prices fell 4-12% from Q4 2012 to Q4 2013. Despite downward trend, large variation in reported pricing within market segment in 2013 A difference of roughly $2.00/W in median reported price between the lowest- and highestpriced states for residential & commercial systems 10 kw, and similar variability also exists within individual states The reported price of utility-scale projects generally ranged from $2.60/W to $3.20/W, though some of those systems may have been contracted in 2010-2012 (or earlier) Difference between reported and modeled system prices for similarly segmented systems in 2013 Residential ($4.69/W reported price, $3.71/W modeled price); commercial ($3.89/W reported price, $2.61/W modeled price); utility-scale ($3.00/W reported price, $1.92/W modeled price) Delta between reported and modeled pricing is due to various factors, such as market fundamentals (e.g., large fraction of data for reported prices is from CA and other high-priced markets), inefficient pricing (i.e., value-based pricing), project characteristics(e.g., highefficiency panels with single-axis tracking), and long temporal lags between contract signing and installation for large utility-scale projects. 30
