Introduction: Iran Solar Energy Market Size Gains Momentum from Policy and Industrial Demand

The Iran solar energy market size was valued at 2.5 gigawatt in 2025 and is estimated to reach 3.41 gigawatt in 2026, with capacity projected to reach 16.14 gigawatt by 2031.

Iran's solar industry is gaining attention as electricity supply pressures encourage utilities, industrial companies, and public institutions to consider renewable generation. The country's high solar irradiation provides a strong foundation for photovoltaic deployment, while policy measures from the Renewable Energy and Energy Efficiency Organization (SATBA) are helping create clearer routes for project development. At the same time, challenges related to subsidized fossil-fuel electricity, foreign-exchange limitations, financing, and grid congestion continue to influence the pace of deployment.

Iran Solar Energy Market Trends

Industrial Solar Demand Gains Importance

Industrial electricity requirements are another major factor influencing the Iranian solar sector. Energy-intensive industries face electricity supply interruptions and seasonal power shortages, creating a direct incentive to develop captive solar generation.

Rural and Off-Grid Solar Deployment Expands

Solar deployment is not limited to large grid-connected projects. Rural and nomadic communities are also creating demand for portable solar systems and small-scale installations. These systems can provide electricity in locations where extending conventional transmission infrastructure is difficult or expensive.

Bifacial Modules and Tracking Systems Support Higher Output

The adoption of bifacial modules and tracking systems is another trend affecting project economics. Import-duty measures for selected solar equipment can help developers access systems capable of improving energy yields, particularly in areas with strong solar resources.
