    Monday Study – Solar’s Growth, Market Share Up-Up-Up

    Tracking the Sun, 2022 Edition

    Galen Barbose, Naïm Darghouth, Eric O’Shaughnessy, and Sydney Forrester, September 2022 (Lawrence Berkeley National Laboratory)

    Summary Brief

    Berkeley Lab’s annual Tracking the Sun report describes pricing and design trends among grid-connected, distributed solar photovoltaic (PV) systems in the United States. This summary brief provides an overview of key trends from the latest edition of the report, based on project-level data for roughly 2.5 million systems installed through year-end 2021, and preliminary data for the first half of 2022. New to the report this year is an expanded coverage of paired PV-plus-storage systems, including details on system design and pricing trends…

    PV System Characteristics

    Characteristics of projects in the data sample help to illustrate trends within the broader U.S. market and provide context for understanding installed price trends. Key technology and market trends based on the full data sample are as follows.

    • Residential PV systems continue to grow in size, with median sizes in 2021 reaching 7.0 kW, while nonresidential system sizes have plateaued (see Figure 1). For the purpose of this report, non-residential systems are defined to include roof-mounted systems of any size and ground-mounted systems up to 5 MWAC. Most are relatively small, with a median of just 33 kW in 2021, but roughly 20% were larger than 150 kW, and the average size among all non-residential systems was roughly 250 kW

    • Module efficiencies have risen steadily over time: for example, among residential systems, median module efficiencies rose from 13.6% in 2002 (the earliest year with sufficient data) to 20.1% in 2021, with similar rises for non-residential systems as well.

    • Module-level power electronics (either microinverters or DC optimizers) have continued to gain share across the sample, representing 94% of residential systems, 81% of small (75%) of non-residential site hosts, with the remainder consisting of some combination of tax-exempt customers (schools, government, nonprofits). As to be expected, TPO is considerably more prevalent among tax-exempt site hosts than for commercial hosts (35% vs. 16% in 2021).

    • Inverter-loading ratios (the ratio of module-to-inverter nameplate ratings) have generally grown over time, and are slightly higher for large non-residential systems (a median of 1.22 in 2021) than for residential and small non-residential systems (1.18 and 1.17, respectively).

    • Roughly half (46%) of all large non-residential systems installed in 2021 are ground-mounted, and 12% have tracking. In comparison, 13% of small non-residential and 2% of residential systems are ground-mounted, and negligible shares have tracking.

    • Panel orientation has remained fairly consistent in recent years, with 54% of systems installed in 2021 facing southward (180±45 degrees), 24% to the west, and most of the remainder to the east.

    • Third-party ownership (TPO) in the residential sample, which includes both leasing and power purchase agreements, has declined over time from a high of 59% of systems installed in 2012 to 28% in 2021. For the non-residential sample, TPO shares have remained comparatively steady and have historically been lower for small vs. large non-residential systems (14% vs. 33% in 2021). In general, TPO shares tend to be higher in states with richer incentives.

    • For-profit commercial customers make up the largest share (>75%) of non-residential site hosts, with the remainder consisting of some combination of tax-exempt customers (schools, government, nonprofits). As to be expected, TPO is considerably more prevalent among tax-exempt site hosts than for commercial hosts (35% vs. 16% in 2021).

    Paired PV+Storage System Characteristics

    This year’s edition of an expanded discussion of trends among paired PV+storage systems, including details on battery storage attachment rates (the percentage of PV installations each year that include storage) and system sizing.

    • Battery storage attachment rates have been steadily rising in the residential sector, reaching 10.0% of the data sample in 2021 (see Figure 2, left). Non-residential attachment rates are lower and have fluctuated over the years, but have been rising recently, reaching 4.9% of all systems installed in 2021.

    • National storage attachment rates largely reflect California, given its large share of the overall market. Hawaii has, by far, the highest attachment rates of any state (93% residential, 59% non-residential in 2021). Other lesser pockets of activity exist in both the residential and non-residential markets. For example, following Winter Storm Uri in Texas, PV+storage adoption rose rapidly, with attachment rates in CenterPoint’s service territory averaging 14% over the year and trending upward.

    • Storage retrofits onto existing PV systems represented about 15% of all paired residential systems installed in 2021, and 9% of non-residential systems. Retrofit applications are significantly more common in California than in most other states.

    • Paired residential systems continue to evolve toward larger storage sizing over time, likely reflecting an increasing focus on backup power applications. Among paired residential systems installed in 2021, roughly 42% had batteries of at least 10 kW in size.

    • In contrast, paired non-residential systems are getting smaller, as uptake expands among smaller customers into applications beyond demand charge management. Of all paired non-residential systems installed in 2021, almost half (46%) had batteries smaller than 10 kW.

    Median Installed-Price Trends

    The installed price data summarized in the report represent prices paid by system owners prior to receipt of any incentives, and are based on a subset of the larger dataset, consisting of only host-owned systems and, unless otherwise noted, only stand-alone PV systems (without batteries).

    • Over the long-term, U.S. median installed prices have fallen by roughly $0.4/W per year, on average, but that price decline has tapered off since 2013, with prices dropping since then at roughly $0.1-0.2/W per year (see Figure 3). Over the last year of the analysis period (2020-2021), median prices fell by $0.1- 0.2/W across all three sectors (in real, inflation-adjusted terms), maintaining recent historical trends. The YoY decline in total installed prices occurred despite a slight uptick in module costs.

    • Preliminary data for systems installed in the first half (H1) of 2022 show that median installed prices for residential systems remained flat (in real terms) compared to the last half of 2021, and continued to fall for non-residential systems. Supply chain constraints, widely acknowledged within the industry as putting upward pressure on prices, may not be fully reflected in prices for installed projects, and are also partly embedded within the inflation adjustment of pricing data into real dollar terms. In nominal terms, median prices residential and large non-residential systems rose in H1 2022.

    • Year-over-year (YoY) pricing trends at the state-level can deviate from national trends, with half of all states showing an increase in median residential prices from 2020-2021, and most states showing a decline in non-residential prices. Over the past 5 years, trends across states are more uniform, with typically a $0.1-0.2/W average annual decline in median residential prices and an annual decline of $0.1-0.3/W in non-residential prices.

    • National median installed prices from the Tracking the Sun dataset are higher than a number of other common PV pricing benchmarks, which generally align more closely with the 20th percentile levels from Tracking the Sun. These differences reflect a diversity of methods, data sources, and definitions. As one specific example, prices reported for loan-financed systems in the Tracking the Sun dataset may include dealer fees, which other benchmarks typically do not include, and may add upwards of 10-25% to the total up-front price paid by the customer.

    • Median prices for PV systems paired with battery storage were $0.6-1.6/W higher than for stand-alone PV systems in 2021, across the three customers segments shown in Figure 4. Using a multi-variate regression analysis, we estimate roughly a $1.9/WPV premium for adding storage to residential PV, assuming a 5-kW battery with 10-15 kWh of storage. Given typical residential PV and storage sizes, this equates to an underlying incremental cost of roughly $1200/kWh of storage, which is in-line with average residential storage costs reported through California’s Self-Generation Incentive Program.

    Variation in Installed Prices

    While trends in median installed prices can be revealing, the installed pricing data also exhibit substantial variability across projects, as shown in Figure 5 below, reflecting underlying differences in project-level characteristics, installer attributes, and features of the local market, policy, and regulatory environment.

    • Installed prices within each customer segment vary substantially depending on system size, with a difference of $1.1/W in median prices between the smallest and largest residential systems, and $2.0/W between the smallest and largest non-residential systems.

    • Installed prices vary widely across states, with state-level median prices ranging from $2.9-4.8/W for residential, $2.1-3.3/W for small non-residential, and $1.5-2.7/W for large non-residential systems. A small part of this state level variation can be explained by feature of local PV markets that are modeled as part of the regression analysis, as discussed below.

    • Across the top-100 residential installers in 2021 (by volume), installer-level median prices generally ranged from $3-5/W, and most had a median price above $4.0/W.

    • Within the non-residential sector, installed prices are higher for systems installed at tax-exempt customer sites, compared to prices for commercial site hosts, though this seems to be uniquely the case in California, which represents a large share of the market. Differences were most pronounced for large non-residential systems in California, where tax-exempt customers paid a median price of $3.3/W in 2021, compared to $1.9/W for commercial customers.

    The full report also provides descriptive trends comparing median installed prices based on module efficiency and the use of MLPEs, though those pricing differences tend to be relatively small and are more clearly defined through the regression analysis below.

    Regression Analysis of Pricing Variability

    We apply a multi-variate linear regression model to estimate the effects of individual factors on installed prices, focusing on host-owned residential PV systems installed in 2021, and including both stand-alone PV and paired PV+storage systems. This statistical model includes variables related to system, market, and installer-level characteristics, as well as state- and quarterly fixed effects variables. Key results from this analysis, as depicted in Figure 6, include the following.

    • Of the system-level pricing drivers, battery storage has by far the biggest effect ($1.9/W), though microinverters, DC-optimizers, ground-mounting, and new construction all have relatively large effects ($0.4-0.5/W) as well.

    • Effects associated with the various market- and installer-related drivers are all relatively small (less than $0.2/W), but in general are directionally intuitive

    • Of particular note is the wide range across the state fixed-effects variables ($1.6/W), suggesting the presence of strong state-level pricing drivers beyond those explicitly captured in the model (e.g., costof-living, retail rates, incentives, solar insolation, permitting processes)…

    ORIGINAL REPORTING: Trying To Make Arizona’s Just Energy Transition More Just

    Stakeholders, Utility Unite in Face-Off with Regulators Over Arizona Just Energy Transition

    Herman K. Trabish, April 28, 2022 (California Current)

    Editor’s note: While calls for energy justice and equity rise across the U.S. and around the world, Arizona’s regulators continue to avoid a decision.

    Arizona Public Service (APS) raised the national standard for a Just Energy Transition with its $144.45 million settlement with affected communities and tribal peoples in late 2020. The money was for assistance to communities impacted by the already-closed coal fueled 2,409 MW Navajo Generating Station and planned 2031 closures of the 2,270 MW Four Corners Generating Station, and the 1,129 MW Cholla Generating Station. Navajo supplied and the Four Corners’ supplies power to California.

    The urgent need for the proposed APS investment to rectify the coal plants’ decades-long destructive impacts was emphasized April 27 in the first of several April-May town hall meetings on the ACC ruling. Chaired by Commissioner Anna Tovar, the citizens of Joseph City, Arizona, testified to coal generation’s pollution of local air, water, health, and economics.

    Endorsed by environmental groups and tribal peoples, the coal plant settlement included $128.75 million for the Navajo Nation, $12 million to Cholla communities, and $3.7 million to the Hopi Tribe. But the plan required Arizona Corporation Commission (ACC) approval. The commission objected to APS’s proposal to recover almost $120 million from ratepayers and sharply cut the amount to be recovered through rates.

    That investment would support “a solid economic transition,” Navajo Nation President Jonathan Nez told this reporter at the time of the agreement. It would “electrify homes, increase renewable energy projects, and promote economic development” and could make Navajo Nation lands “a renewable energy epicenter,” Nez said.

    As Western utilities close uneconomic coal facilities, affected communities and advocacy groups are pushing for economic justice in the transition to clean energy. Landmark efforts include Washington state’s $55 million in 2011, New Mexico’s $40 million in 2019, and the April 26, 2022, agreement for closure of Xcel Colorado’s Comanche facility, which could approach APS’s proposed expenditure.

    The APS plan would likely be the biggest just transition utility expenditure in the U.S. to date, according to APS and Arizona State University Just Energy Transition Center Co-Director Amanda Ormond. The ACC disrupted that ambition. In its final decision late last year, concerned about costs to APS’s 1.2 million Phoenix and central Arizona customers, the commission reduced the proposed $119.25 million ratepayer share of the Just Energy Transition payment to $10 million… click here for more

    Solar Prices Keep Getting Better

    US installs record solar capacity as prices keep falling; It's often cheaper to build and run solar than to buy gas for an existing plant.

    John Timmer, September 21, 2022 (Ars Technica)

    “…The annual Energy Department analysis found solar energy was nearly half of new U.S. 2021 generating capacity partly] because costs have dropped by more than 75 percent since 2010…[and] it's now often cheaper to build and operate a solar plant than it is to simply buy fuel for an existing natural gas plant…[Incentives and tax breaks in the Inflation Reduction Act] should expand solar's advantages…[Over 12.5 gigawatts of new utility-scale capacity was built] last year, bringing the total installed capacity to over 50 gigawatts…

    Combined with residential and other distributed solar installations, solar alone accounted for 45 percent of the new generating capacity added to the grid last year…[The] expansion has largely been driven by falling costs…[T]he price of building a solar plant has been dropping by an average of about 10 percent a year…[Prices averaged] about $1.35 for each watt of capacity in 2021. Large-scale plants benefit the most, with projects over 50 megawatts costing about 20 percent less…

    …[It is] becoming increasingly economical to install large facilities in states that don't get as much sun…[making the median capacity factor of solar plants in the US was 24 percent…[With the drop in construction costs, solar’s LCOE without federal tax incentives has dropped 85 percent since 2010, from $230/MWh to $33 per MWh] and utility-scale and distributed solar growth is forecast to] triple by the end of the decade, reaching about 75 GW in 2030, and continuing to grow from there…” click here for more

    Monday Study – New Insights On The Impacts Of Electricity Costs

    Paying for Electricity in California: How Residential Rate Design Impacts Equity and Electrification

    September 2022 (The Energy Institute at UC Berkeley’s Haas School of Business via Next 10)

    EXECUTIVE SUMMARY

    California has ambitious goals to fight climate change while also ensuring that energy is affordable for all of its residents. Unfortunately, the current structure of residential electricity prices in the state makes achieving these goals much harder. Electric utility rates feature high volumetric (i.e., per kilowatt-hour) prices that are designed to recover many costs beyond the direct incremental cost of providing electricity. These high volumetric prices make electrification less attractive to consumers while simultaneously distributing the burden of paying for electricity in a way that is quite regressive.

    In this report, the authors analyze detailed billing data from over 11 million California households served by the state’s three large investor-owned utilities (IOUs)—Pacific Gas and Electric (PG&E), Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E)—in order to characterize the implications of the current residential electricity prices for equity and for electrification of vehicles and homes. The authors then discuss potential reforms that could simultaneously improve equity while fostering decarbonization by removing barriers to electrification.

    This report builds on a prior companion report that established key facts about retail electricity pricing in California.1 First, the initial study showed that IOU customers face prices that are two to three times higher than social marginal cost (SMC), which is defined as the going-forward cost to the utility of providing additional electricity to an existing customer, inclusive of pollution costs. Second, the initial report also found that the reason that retail prices are so far above the efficient SMC benchmark is that retail prices are used to recover non-incremental costs of electricity supply along with other programs that have been integrated into bills. This method of cost recovery has generated a large, and rapidly growing, gap between retail electricity prices and social marginal costs. The report authors refer to this gap as the effective “electricity tax.”

    This report explores the consequences of this effective electricity tax on equity and efficiency and ultimately finds that reforms could better align electricity rates with the state’s climate and clean energy goals. Using the detailed billing data, the residual cost burden for each customer—defined as the difference between the amount the customer pays on their bill and the incremental cost to the utility of providing that household with power—is calculated under the current rate system. The distribution of those residual cost burdens across the income distribution is then characterized.

    Customers do not see their bill broken into “incremental costs” and “residual cost burden,” so the drivers of escalating retail prices are opaque to the typical customer. A primary goal of this analysis is to bring to light essential facts about the current system—who is paying for California’s electricity system today? and how is that determined by specific features of current rates?—in order to better inform public discussion. Household & Equity Impacts: This report offers a firstof-its-kind analysis for California that demonstrates how residual cost increases for customer electricity bills are impacting households and how that impact varies across households with different abilities to pay.

    The analysis presented in this report finds that:

    • Overall, customers across the three IOU service territories contribute $678 per year on average toward the residual cost burden. For PG&E and SDG&E customers, residual cost burdens are more than twothirds of their total bills, whereas SCE customers pay slightly more than half of their bills towards residual costs. As a result, how California chooses to recover these costs is the primary driver of electricity costs.

    • Residual cost burdens vary widely across households. As of 2019, a quarter of households were contributing less than $220 per year, while the quarter of households with the highest usage contributed more than $850 per year.

    • California’s current electricity pricing regime assigns a greater share of residual costs to higher-income households, but lower-income households pay much more as a fraction of their annual income on average, so much so that the effective electricity tax is more regressive than the state sales tax. Figure ES.1 summarizes these data for 2019: it shows the estimated average residual cost burden by income category for each household (in solid lines, which rise with income), as well what fraction of average income this represents (in dashed lines, which decline with income).2

    • Net metering for rooftop solar makes the effective electricity tax substantially more regressive. This is because wealthier households are much more likely to have rooftop solar. The effect is strongest in SDG&E, where rooftop solar in 2019 already provided over 20 percent of residential electricity under net metering, thus offsetting a majority of the cross-subsidy created by the California Alternative Rates for Energy (CARE) program.

    Impacts on Decarbonization Efforts:

    The state’s strategy for decarbonization includes plans for widespread electrification of buildings and rapid electrification of personal transportation. Relying entirely on the effective electricity tax to recover residual costs, however, implies that customers considering electrification face much higher operating costs if they electrify than they would if prices were set equal to social marginal cost. The authors refer to this increase in operating costs as the “electrification cost premium.” Related to this issue, this analysis finds that:

    • For California households considering purchasing an electric vehicle (EV), the effective electricity tax raises the annual operating cost of an EV by around $600 per year on average. Recent research suggests that this could be reducing EV adoption by somewhere between 13 and 33 percent. Figure ES.2 shows the average annual electrification cost premium for EVs across the utilities. The premium is close to $900 for the average SDG&E customer.

    • For households considering electric heating in lieu of natural gas, the effective electricity tax raises the annual cost of doing so by around $600 per year. Recent research suggests that eliminating this tax could increase the fraction of new homes that are built with electric heating by around one third. Figure ES.2 shows how the electrification cost premium for home heating varies across the utilities, with the highest annual burdens, around $850 on average, in PG&E.

    Fortunately, there are ways that residential electricity rates could be reformed in order to foster electrification (by lowering volumetric prices), while simultaneously improving equity outcomes. Some of these possible reforms were discussed in the previous related report,3 but with the detailed billing data available for this report, the authors are now able to examine their impacts much more closely. They find that:

    • Moving some costs that contribute to the residual cost burden onto the state budget, to be funded by increases in the sales or income tax, would increase equity and improve efficiency because it would reduce the effective electricity tax. A variety of costs that might be moved are discussed, including public purpose programs, legacy costs and costs related to wildfires.

    • Introduction of income-based fixed charges would similarly increase equity and efficiency at the same time. As an example, the authors consider a system of income-based fixed charges that would mimic the progressivity of the state’s sales tax, showing the rates needed and the distribution of bill changes it would induce.

    • Minimum bills, which have been suggested as a potential source of funds to cover the residual cost burden, would be both ineffective and highly inequitable. The report authors conclude that minimal bills are more regressive than even the current rate structure, as more than half of the added revenues from a minimum bill would be paid by households with below-median income. In addition, minimum bill levels that have commonly been discussed in the current debate, such as $30 per month, would make an extremely small contribution to covering the residual cost burden.

    Some of the challenges with rate reforms are discussed in this report. The authors also note that, even where it is possible to pursue rate reforms that are equitable on average across income categories, their analysis of the billing data makes clear that there would be a wide distribution of resulting winners and losers—which could make it more difficult to reach political consensus on reform.

    In this report, the authors take as given the amount of revenue that utilities need to recover. Another important policy direction is to identify and reduce any costs due to inefficiency or unnecessary expenditures, but that is not pursued in this report. Also, this report focuses exclusively on residential electricity rates. Commercial and industrial electricity rates are also used to cover costs above SMC, raising many of the same issues around electrification, as well as different concerns over equity and business climate in California.

    Given this context and these complexities, this report is first and foremost aimed at providing useful facts and outlining possible paths forward, guided by the twin objectives of fostering decarbonization and improving equity. All possible reforms create some manner of trade off, and as such should be debated in the broader policy context in the state.

    Earth’s Numbers Show Record-Breaking Heat

    Earth had its 6th-warmest August on record; Antarctic sea ice set record low; Northern Hemisphere saw its 2nd-hottest summer

    September 14, 2022 (National Oceanic and Atmospheric Administration)

    “…The average global land and ocean surface temperature in August was 1.62 degrees F (0.90 of a degree C) above the 20th-century average of 60.1 degrees F (15.6 degrees C), making it the sixth-hottest August in the 143-year global climate record…North America and Europe both had their hottest Augusts on record as Asia recorded its fourth-hottest August. South America, Africa and the Oceania region all had warmer-than-average Augusts but none saw a top-10 warm August…

    …The season was Earth’s fifth warmest on record — tied with 2015 and 2017 — at 1.60 degrees F (0.89 of a degree C) above the 20th-century average. The five warmest June-August periods on record have occurred since 2015…[There is now] a greater than 99% chance that 2022 will rank among the 10-warmest years on record…For the third consecutive month, Antarctica set a record low sea ice extent (coverage) since records began in 1979…The globe saw nine named storms in August: Four of the nine named storms reached tropical cyclone strength (74 mph or higher), including Super Typhoon Hinnamnor, the first Category 5 tropical cyclone of 2022…” click here for more

    New Energy Could Save $$$Millions

    Switching to renewable energy could save trillions – study

    Jonah Fisher, 13 September 2022 (BBC News)

    “Switching from fossil fuels to renewable energy could save the world as much as $12tn (£10.2tn) by 2050, an Oxford University study says…Gas prices have soared on mounting concerns over energy supplies…[and] going green now makes economic sense because of the falling cost of renewables…

    …[Historic price data for renewables and fossil fuels show] the price of renewables will continue to fall is based on ‘probabilistic’ modelling, using data on how massive investment and economies of scale have made other similar technologies cheaper…Wind and solar are already the cheapest option for new power projects, but questions remain over how to best store power and balance the grid when the changes in the weather leads to fall in renewable output…[but the] likely costs have been over-estimated…[and the transition to renewables is likely to have] a net economic benefit…” click here for more
