**5.1.1 Thermocouple sizing**

The process of PV array sizing was utilized in determining the number of thermocouples to give the desired amount of electrical power required. To achieve this, the amount of electrical power required by the load and the amount of solar energy available at the site are necessary. The amount of ampere load energy demand required for a fixed load such as 2 DC T8 2ft fluorescent tube is 5.14Ah. Therefore the total demand in ampere-hours is 5.14Ah.
