Abstract

Solar energy is leading the charge in the shift to renewable energy sources because of its sustainability and abundance. With the use of remote sensing data and Geographic Information System (GIS) technology for land suitability research, this study evaluates the viability of developing solar farms in Baqubah City, Diyala, Iraq. Iraq is well-positioned for the spread of solar power due to its growing energy demand and dedication to diversifying its energy mix. Key elements included in the analysis were slope, land cover, solar irradiation, proximity to transmission lines, and environmental restrictions. A comprehensive suitability map classifying land into high, moderate, and low potential zones for solar farms was created by integrating spatial data using a GIS.
According to the findings, about 25% of Baqubah is very ideal for the establishment of solar farms, mostly in flat, bare areas with strong solar radiation and easy access to the transmission infrastructure that is already in place. About 40% of land is covered by moderate suitability zones, which are frequently constrained by partial land cover limitations or higher slopes. The remaining 35% are low suitability zones, which include locations that are environmentally protected, agricultural, or densely populated.
The study aids Baqubah local government in achieving its sustainable development and renewable energy targets by identifying investment-friendly locations that balance technical viability and environmental stewardship, thereby guiding strategic planning for solar energy projects.
