サウジアラビアで普及が遅れる住宅用太陽光について、新築ヴィラ開発への設置義務化という政策設計を検討した研究。個々の homeowner 判断に頼らず建設時に一括導入することで、開発者・住民・国内再エネ市場の利害を両立させる。1万戸・120MWpの想定で単純回収約12.4年、年約12.3万トンのCO2削減効果を示す。
English
This study designs a mandatory rooftop-PV requirement for new villa developments in Saudi Arabia to expand distributed solar while balancing developer, resident, and market interests. Installing PV during construction avoids individual homeowner adoption barriers. A 10,000-villa scenario yields 120 MWp, 216 GWh/year, ~12.4-year simple payback, and ~122,700 tCO2 avoided annually.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では2025年4月から東京都の新築住宅への太陽光設置義務化が始まり、本稿の政策設計・回収年数・市場創出の議論は自治体制度設計の比較材料になる。ただし料金・補助制度の前提はサウジ固有で、そのままは適用できない。
In the global GX context
Adds to the global literature on building-integrated and mandated distributed solar, complementing EU solar mandates and US state-level policies. It offers a Gulf-region case on how construction-stage mandates can aggregate demand and de-risk PV markets, relevant to ISSB/transition-plan discussions on Scope 2 and renewable procurement.

📄 Abstract（原文）
<title>Abstract</title> <p>Saudi Arabia possesses a great deal of solar energy potential, yet the adoption of decentralized PV systems remains low in the kingdom. Low electricity tariffs, high upfront capital costs, and other constraints have all been causes of low residential PV adoption among homeowners. This study examines how a mandatory rooftop-PV requirement for new villa developments could be designed to expand distributed solar generation in Saudi Arabia while balancing the financial interests of developers, benefits to residents, and the development of a domestic renewable-energy market. Rather than relying on individual homeowners to install PV systems, this study recommends that new villa developments install PV systems during construction. This avoids the need for separate homeowner adoption decisions, which tends to be less financially attractive for the individual homeowner. This study uses four different Saudi residential-PV studies for each one of the three key parameters: PV capacity, PV yield, and Installation costs. In a hypothetical scenario where 10,000 villas are planned for construction in a given neighborhood under the policy design, PV capacity is 120 MWp, annual generation is 216,000,000 kWh/year = 216 GWh/year, and total installed cost is SAR 480 million. The simple tariff-equivalent payback would be roughly 12.4 years. As a result, approximately 122,700 tonnes of CO₂ emissions could be avoided annually if the full 216 GWh of annual PV generation displaced grid electricity at the Saudi emission factor. The framework could potentially create an aggregated and predictable PV market for PV manufacturers, electrical contractors and engineering firms, while creating conditions conducive to greater private-sector participation.</p>
