Due to the increasing demand of high performance solar cells with low cost. A comparative study between the materials gallium arsenide (GaAs) and silicon (Si) takes place in this work. We show that (GaAs) responds differently than (Si) at the same conditions, the GaAs module produced more power at increasing temperature. Two approaches are applied, photovoltaic system (PV) without tracking system (Fixed System) and PV with manual tracking systems to show the differences between using (Si) and (GaAs) solar cells. Results show that energy produced by GaAs PV system generates more energy than that produced by silicon PV system. Knowing that the cost per produced KWH is less in case of using fixed panels. A comparison is done between the cost of both systems shows that the system that use (Si) has low cost than the system that use (GaAs).
