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 america, together with the rising contingent of distributed solar-plus-storage programs. The report relies on information from roughly 3.7 million programs put in nationally by way of 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 yr’s report updates key developments associated to venture traits, system design, and pricing, and presents new materials counting on constructing and property information built-in into the Monitoring the Solar dataset.

The report, printed in slide-deck format, is accompanied by a story govt abstract, interactive information visualizations, and a public information file, all accessible by way of 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 just a few key findings from the newest version of the report.

Residential programs proceed getting bigger, pushed by rising 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 almost in lock-step with PV module efficiencies, as proven within the left-hand panel of Determine 1. Greater module efficiencies permit for extra PV capability, as residential programs are sometimes space-constrained on account of shading, obstructions, and blended 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 purposes and have risen solely barely since 2010.

Non-residential PV adopters span a various set of sectors, as small agricultural programs increase their share. As proven in Determine 2, half of all non-residential installations in 2023 had been put in on business properties (together with retail, industrial, workplace, warehouse amenities), roughly one-third on agricultural properties, and 15% by tax-exempt (e.g., authorities, colleges, spiritual, 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 yr. Most of these programs had been put in underneath the state’s legacy internet metering construction, however attachment charges for programs put in underneath the brand new internet billing tariffs, which strongly incentivize pairing PV with storage, reached roughly 60% by year-end. (Berkeley Lab beforehand printed a extra in-depth evaluation of modifications within the California photo voltaic market underneath the brand new internet 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 initiatives 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 initiatives. 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 venture traits in addition to options of the native market, coverage, and regulatory atmosphere. The report features a multi-variate regression evaluation that estimates the results of key pricing drivers on residential put in costs in 2023. The regression evaluation reveals probably the most vital impacts related to the inclusion of battery storage (a $1.4/W improve), variations in system measurement (a $0.7/W lower from the 20^th to the 80^th percentile system measurement), and installations on residential new building ($0.7/W decrease than programs put in on current houses).

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