Abstract :

This research examines the impact of factors engineering dimensions of the anodes in different soils on solar energy system design as a major source of impressed current required for cathodic protection of 100 m oil pipeline steel. This paper deals with various resistance of the soils starting from (50 Ohms.Cm) in the north to (5000 Ohms. Cm) in the south of the land of Iraq. The results showed that the anodes of lengths (48, 24.9 and 6.02 cm) in low–resistivity soils (50 ?.cm) require low potentials (2.77, 2.82 and 3.08 V) respectively. One solar panel (13 W) is fair enough in the low soil resistivity (50 ?.cm).
