Saudi Arabia Launches National Residential Rooftop Solar Pilot

Saudi Arabia's Ministry of Energy and the Renewable Energy Project Development Office (REPDO) have launched a nationwide residential rooftop solar pilot program targeting 50,000 homes across Riyadh, Jeddah, Dammam, and three secondary cities by end of 2027. The program is part of the broader Vision 2030 strategy to derive 50% of the kingdom's electricity from renewable sources by 2030. Pilot participants benefit from streamlined Saudi Electricity Company (SEC) interconnection processes, subsidized installation costs through SIDF financing, and a 10-year warranty pool covering eligible equipment. While the kingdom's residential electricity tariffs remain among the lowest in the world (SAR 0.18/kWh for the first 6,000 kWh of monthly consumption), the program's economics rely primarily on tariff subsidies being phased down for high consumption tiers — where rates can reach SAR 0.30/kWh — combined with the kingdom's exceptional solar irradiance averaging 6.6 peak sun hours daily. The 0% import duty on solar equipment under the GCC Unified Customs Tariff classification continues to keep equipment costs competitive, with installed system prices for residential systems averaging USD 0.70–0.90 per watt. The Saudi Standards, Metrology and Quality Organization (SASO) has also issued updated technical specifications for residential PV equipment to ensure compatibility with the country's harsh thermal conditions, where ambient temperatures regularly exceed 45°C in summer.
