フロリダの柑橘産業はHLBにより9割超が崩壊した。本研究は、アジア柑橘キジラミを遮断しつつ発電も行う垂直型アグリボルタイック遮蔽壁を提案し、35エーカー農場で技術経済評価を実施。周囲フェンス型で20.34%、内部風防追加型で29.51%のROIを達成し、州全体で11.9GW・15.4TWhの電力を耕作地を犠牲にせず供給可能と示した。

English

Florida's citrus industry has collapsed >90% due to HLB spread by the Asian citrus psyllid. This study proposes vertical agrivoltaic shield walls that exclude the pest while generating electricity, evaluated on a 35-acre farm. Perimeter-only and perimeter-plus-interior designs achieve 20.34% and 29.51% ROI on energy alone, with statewide potential of 11.9 GW and 15.4 TWh without sacrificing growing area.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本では耕作放棄地や営農型太陽光（ソーラーシェアリング）の収益性・制度設計が政策課題であり、病害防除と発電を両立する自己資金モデルは、農林水産省の営農型太陽光ガイドラインや地域脱炭素の議論に示唆を与える。

In the global GX context

While focused on Florida, this work advances the global agrivoltaics literature by showing dual-use land can self-fund biosecurity, relevant to CSRD/ISSB disclosure of land-use and renewable generation and to transition finance for agricultural resilience.

👥 読者別の含意

📄 Abstract（原文）

The Florida citrus industry has collapsed by >90% in two decades, driven primarily by Huanglongbing disease transmitted by the Asian citrus psyllid (ACP). While physical barriers such as citrus under protective screens systems effectively exclude ACP, their high capital costs ($43,560/acre) yield payback periods >29 years, making them economically unviable for most growers. This study investigates vertical agrivoltaic shield walls as a self-funding biosecurity solution that combines ACP exclusion with sustainable electricity generation. A case study is presented evaluating a representative small-family farm-sized (35 acres) citrus grove. Structural designs compliant with Building Code and ASCE 7-22 were developed, and two deployment scenarios were simulated in Vero Beach, Florida: perimeter-only fencing (622.6 kW-DC, Case 1) and perimeter plus interior wind shields (954.8 kW-DC, Case 2). Techno-economic analysis under FPL tariffs shows 25-year bill savings of $1.27M (Case 1) and $1.97M (Case 2) under net metering, invariant across sub-cases. Under the owner-developed deployment, both cases achieve positive ROI on energy economics alone (Case 1: 20.34%, Case 2: 29.51%), while wholesale export under COG-1 is uniformly uneconomic. GIS-based statewide scaling indicates that fence-mounted PV on Florida citrus groves alone could provide 11.9 GW of capacity generating 15.4 TWh annually. This would produce 6% of Florida's electricity consumption or raised to 25.5% if extended to the rest of the state’s farmlands producing 65.03 TWh without sacrificing any growing area. The economic results are promising as they indicate agrivoltaic shield walls can simultaneously combat HLB, diversify farm revenue, and accelerate sustainable and renewable energy generation.
