We’re happy to announce the discharge of the newest version of Berkeley Lab’s Monitoring the Solar annual report, describing developments for distributed photo voltaic photovoltaic (PV) programs in the USA, together with the rising contingent of distributed solar-plus-storage programs. The report is predicated on knowledge from roughly 3.7 million programs put in nationally via year-end 2023, capturing near 80% of all programs put in as much as that time and greater than 70% of additives in 2023. This 12 months’s report updates key developments associated to challenge traits, system design, and pricing, and presents new materials counting on constructing and property knowledge built-in into the Monitoring the Solar dataset.

The report, revealed in slide-deck format, is accompanied by a story govt abstract, interactive knowledge visualizations, and a public knowledge file, all accessible via the hyperlink above. The authors will host a webinar summarizing key findings from the report on September 4^th at 10 am Pacific.

The next are a couple of key findings from the newest version of the report.

Residential programs proceed getting bigger, pushed by growing module effectivity. Residential system sizes have risen steadily over the previous 20 years, reaching a median of seven.4 kW in 2023. System sizes have grown practically in lock-step with PV module efficiencies, as proven within the left-hand panel of Determine 1. Increased module efficiencies enable for extra PV capability, as residential programs are sometimes space-constrained attributable to shading, obstructions, and combined roof orientations. As proven within the right-hand panel of Determine 1, roof-coverage ratios (the share of roof-space utilized by the PV modules) usually vary from 20-40% in residential functions and have risen solely barely since 2010.

Non-residential PV adopters span a various set of sectors, as small agricultural programs develop their share. As proven in Determine 2, half of all non-residential installations in 2023 have been put in on business properties (together with retail, industrial, workplace, warehouse services), roughly one-third on agricultural properties, and 15% by tax-exempt (e.g., authorities, faculties, non secular, and different non-profit) prospects. The share of programs put in on agricultural properties has been rising over time; most of those are comparatively small programs (

Battery storage attachment charges proceed inching upwards. In 2023, 12% of all new residential PV installations and eight% of all non-residential installations included battery storage. As normal, Hawaii was in a class of its personal, with residential and non-residential storage attachment charges of 95% and 88%, respectively. Residential attachment charges in California rose to 14% for the 12 months. Most of these programs have been put in below the state’s legacy web metering construction, however attachment charges for programs put in below the brand new web billing tariffs, which strongly incentivize pairing PV with storage, reached roughly 60% by year-end. (Berkeley Lab beforehand revealed a extra in-depth evaluation of modifications within the California photo voltaic market below the brand new web billing construction.) Residential attachment charges in most different states ranged from 4–10% in 2023. Non-residential attachment charges additionally range extensively throughout states, however are usually fairly low (

PV system costs fell year-over-year for residential programs, however rose for non-residential programs. From 2022 to 2023, median put in costs for residential programs fell by roughly $0.1/W in actual (inflation-adjusted) phrases, the identical fee of decline as over the previous decade. In distinction, median costs for non-residential programs rose for the primary time in 15 years, by $0.1-0.2/W. These small year-over-year modifications are delicate to fluctuations in inflation, and the lagged impact on put in costs, which may range throughout tasks relying on the size of their improvement timeline. Throughout all three buyer segments, however particularly for residential programs, put in costs consist predominantly of enterprise course of and different “soft costs”.

PV system costs range extensively throughout particular person tasks. Amongst stand-alone PV programs, put in costs range by roughly $2/W between the 20^th and 80^th percentile values for each residential and small non-residential prospects, and by roughly $1.4/W for giant non-residential prospects (see Determine 4). That pricing variability displays variations in challenge traits in addition to options of the native market, coverage, and regulatory surroundings. The report features a multi-variate regression evaluation that estimates the consequences of key pricing drivers on residential put in costs in 2023. The regression evaluation reveals essentially the most vital impacts related to the inclusion of battery storage (a $1.4/W improve), variations in system dimension (a $0.7/W lower from the 20^th to the 80^th percentile system dimension), and installations on residential new development ($0.7/W decrease than programs put in on current properties).

We thank the U.S. Division of Vitality Photo voltaic Vitality Applied sciences Workplace for his or her help of this work, in addition to the quite a few people and organizations who generously offered knowledge for this ongoing effort.
