本論文は、ウズベキスタンの研究機関の駐車場屋根に設置された20kW級太陽光発電所の実運用データに基づき、NPV、IRR、LCOE、割引回収期間を用いて財務効率を評価した。自家消費モデルが小規模太陽光発電にとって費用対効果が高いことを示し、割引回収期間は4.75年と算出された。
English
This paper evaluates the financial efficiency of a 20 kW solar PV plant installed on a parking structure in Uzbekistan, using real operational data. Financial metrics (NPV, IRR, LCOE, DPP) show that on-site consumption is cost-effective, with a discounted payback period of 4.75 years.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、自家消費型太陽光発電の経済性評価はFIT終了後の再エネ主力電源化に向けた重要な論点であり、本論文の実データに基づく評価手法は参考になる。ただし、ウズベキスタンの電力料金や通貨事情が前提のため、そのまま適用はできない。
In the global GX context
This paper provides empirical evidence on the financial viability of small-scale solar PV for self-consumption, relevant to global discussions on decentralized renewable energy and corporate PPAs. The methodology (NPV, IRR, LCOE) is standard, but the case is from Uzbekistan, offering insights for emerging economies.
👥 読者別の含意
🔬研究者:Provides a real-world case study of financial metrics for small-scale solar PV, useful for comparative analysis.
🏢実務担当者:Offers a template for evaluating on-site solar projects, but note the local context.
🏛政策担当者:Highlights the cost-effectiveness of self-consumption models, which could inform renewable energy incentives.
📄 Abstract（原文）
The article evaluates the financial efficiency of a 20 kW class solar photovoltaic power plant installed in a parking structure on the territory of the National Research Institute of Renewable Energy Sources based on real operational data. The plant consists of 45 Green Sun Solar photovoltaic modules with a power of 410 W, and the total nominal DC power of the modules is 18.45 kWp. In January-July 2026, the plant generated 13,600 kWh of electricity. 100% of the generated energy was directed to cover the internal electricity consumption of the institute. The financial assessment used net present value (NPV), internal rate of return (IRR), levelized cost of electricity (LCOE), and discounted payback period (DPP). The baseline calculation resulted in an NPV of 88.7 million soums, an IRR of 28.4%, an LCOE of 542 soums/kWh, and a discounted payback period of 4.75 years. The results showed that on-site consumption of the generated electricity is a cost-effective model for small-scale photovoltaic power plants.
