Abstract: In large quantities, solar energy is released from the sun's surface. However, we can convert only some part of its reaching the earth's surface into valuable forms of energy for utilization such as thermal, electrical, or mechanical. As proposed in this research to determine the most suitable site for the installation of Photovoltaic power solar station in Borno state, Nigeria using satellite images. Annual global solar irradiance for satellite images was obtained and validated with annual global irradiance calculated from meteorological data. It can also determine Slope, Aspect, Road, Grid network, and temperature. We used an analytical hierarchy process to determine the percentage weight of each factor. We have also applied the Weighted Overlay tool to multiply the input raster, producing a final constraints layer of the most suitable area. The Annual global solar irradiance was obtained as 2240.10 Kilo-Watt-hour/meter2/year for meteorological station data and 2244.98 Kilo-Watt-hour/meter2/year for satellite images data with the validation difference of 0.88 Kilo-Watt-hour/meter2/year. The coefficient of determination R2=0.778. For Slope = 0 to 89.18-degree rise, Aspect =-1 to 359 degrees, Road & Grid network = 0 to 1.31km and Temperature = 22.20 to 29.80 degrees Celsius. The weight of each factor was determined as: Slope=13%, Aspect=13% Road & Grid =5%, Temperature=5% and Global solar irradiance =64%. The most suitable area for installing a solar station was an estimated 39,426 square kilometers, mostly in the northern and some central parts of the study area, which is about 54.5% of the total land mass of Borno state. The annual global solar irradiance obtained from satellite images was converted into electric energy by different solar cell technologies: Single crystalline Silicone=1101Mega Watt, Multi crystalline Silicone=1019 Mega Watt, amorphous Silicone=440.5 Megawatt and Cadmium Tellurium=798.5 Megawatt. It found that the main factors for installing the solar station were global solar irradiance, temperature, topographical Slope and aspect, and nearest to the road and grid network. The global solar irradiance estimated in the study area is adequate to generate sufficient electrical energy for the Borno state. We found the satellite imagery data method to effectively identify suitable sites for the solar station to install a Photovoltaic power plant.
