NZ agri-PV capital-cost benchmark
North Canterbury sheep-and-beef, fixed-tilt case: DC 3,346.2 kWp, AC 2,500 kWac, PV array 5.8 ha. Total modelled capital = Development/Consent/Grid NZD 625k + Design & Build NZD 4.7–6.3 million = NZD 5.325M–6.925M. Derived unit cost = NZD 1,591–2,070/kWp DC (midpoint ~1,830), equivalently ~NZD 2,130–2,770/kWac. This is a modelled Infratec feasibility cost, not an invoice. ⚠ Basis caveat for the modeller: on a DC basis this sits at-to-slightly-above the engine’s ~NZD 1,600/kWp ground-PV proxy (grazing-height agri-PV = MODEST premium); on an AC basis the premium is much larger. Confirm whether the engine’s ~1,600 proxy is DC or AC before applying this figure.
Summary
An Our Land & Water Rural Professionals Fund 2022-23 report (published June 2023 by Tambo, with Alan Brent of Victoria University of Wellington and techno-economic modelling by Infratec New Zealand) examining agrivoltaics — the integration of solar PV generation with livestock farming — in Canterbury, Aotearoa New Zealand. It works two Canterbury case studies, a dairy farm and a sheep-and-beef farm, each with a technical design (fixed-tilt vs single-axis tracking) and a financial analysis, plus a farmer design-thinking workshop.
For Neobiome the load-bearing content is the sheep-and-beef case study’s technical + cost tables (Tables 2–4), which give explicit DC/AC capacities, PV array area and a modelled capital-cost range for a grazing agrivoltaic on NZ farmland. This is the first genuinely NZ-specific agri-PV cost datapoint in the corpus (previous agri-PV evidence was German — OT_050 — or Hungarian — Interview II [INT_002]), and it lets a per-kWp benchmark be derived for the NZ layer of agro_pv that the wider RT_108 umbrella was opened to fill.
The report’s own headline finding is directional and design-useful: agrivoltaics offered sheep-and-beef farmers a significant profitability opportunity (a complementary revenue stream at a time of low farmgate prices), whereas on the dairy case it was “significantly less lucrative” and better suited to shed roofs or non-productive corners than to a full agrivoltaic. The dairy penalty is a cost driver worth carrying: the report attributes the dairy system’s higher capital cost to the greater panel height needed to let cows graze underneath — so cattle-clearance (elevated) designs cost more than the sheep-grazing-height (near-ground, fixed-tilt) design this page’s figures describe.

SINGLE-AXIS TRACKING total = 625,000 + 4,300,000 to 5,700,000 = NZD 4.925M to 6.325M; on 2,692.8 kWp DC = NZD ~1,830-2,350/kWp DC.

'End of panel life replacement and safe disposal and recycling has not been accounted for in this analysis.

Feeds d01_renewable_energy_storage as the NZ-specific agri-PV capital-cost benchmark. The engine currently prices dual-use / grazing PV off a ground-PV proxy (~NZD 1,600/kWp). This source supplies the first NZ datapoint to calibrate an agri-PV cost line: a grazing-height fixed-tilt system on North Canterbury sheep-and-beef land at a derived NZD 1,591–2,070/kWp DC (midpoint ~1,830) OT_202.
How to apply it — one caution before wiring:
| Basis | Derived agri-PV cost (fixed-tilt) | Relation to engine’s ~NZD 1,600 ground-PV proxy |
|---|---|---|
| DC (3,346.2 kWp) | NZD 1,591–2,070/kWp DC (~1,830 mid) | At-to-slightly-above → modest grazing-height premium |
| AC (2,500 kWac) | NZD 2,130–2,770/kWac | Well above → large premium |
The DC-vs-AC gap is ~1.34× (DC/AC ratio here). Confirm the engine’s ~1,600 proxy is stated on a DC basis before applying this number — mixing bases would over- or under-state the agri-PV premium by roughly a third. This is a modelling check to run against the existing energy params, not a new research target OT_202.
Design nuance the cost reflects: the sheep-grazing-height (near-ground, fixed-tilt) design carries only a modest premium; the report shows the cattle-clearance (elevated) dairy design costs more because of the extra mounting height. So an NI agri-PV cost lever should scale with livestock class / required ground clearance, not be a single flat premium OT_202.
No engine cell is auto-changed by this ingest — it supplies the NZ benchmark and its basis caveat; wiring the agri-PV cost line is a separate, reviewed modelling step.
Notes
data_quality: medium, two independent reasons. (1) The capital figures are a project-modelled techno-economic feasibility estimate by Infratec New Zealand, explicitly “subject to further site investigations” and sensitive to site conditions, grid capacity and scope split — not an audited build invoice; and end-of-life recycling is excluded. (2) The raw was AI-retrieved (see Retrieval provenance). The offsetting strength is that it is NZ-specific, transparent, and every table figure was re-verified verbatim against the PDF.- The per-kWp is a derivation made on this page, shown step-by-step in the key_claims, not a number the report prints. The report gives capacities (Table 2) and a capital range (Table 4) separately; the division is ours.
- Scope of this page = the sheep-and-beef case study. The report also contains a dairy case study (235 ha, 860 cows, 2 ha dryland corner) which it finds a poorer agri-PV fit; that case is summarised qualitatively above but its tables are not transcribed here (not the model-relevant cost anchor).
- Consent flag: the report itself notes the National Policy Statement on Highly Productive Land 2022 “places limitations on development of Aotearoa New Zealand’s most fertile and versatile land and this will likely affect solar development applications.” The NZ consent pathway is handled by the sibling NPS-HPL source, not restated here.
- Fixed-tilt frame in the sheep-and-beef case is a Schletter FS Duo Frame (near-ground, sheep grazing underneath); the industry grazing GCR references it cites are 44% fixed-tilt / 33% tracking (Horowitz et al. 2020).
Research targets
Documents to retrieve
- None. This source supplies the NZ-specific agri-PV capital cost (North Canterbury grazing agrivoltaic, derived NZD 1,591–2,070/kWp DC) that the agri-PV cost question was asking for; the density, land-retention, yield and consent questions are covered by the sibling agri-PV sources.
Research gaps
- No new RT opened. The one open modelling question this source raises (confirm the engine’s ground-PV proxy basis, DC vs AC, before applying the derived per-kWp) is a modelling-judgment check carried on this page (NI relevance table above), not a retrievable document.

This raw was obtained by an AI retrieval pass (not a hand-download), so it carries a provenance block. The figures were nonetheless re-verified verbatim against the downloaded PDF.
