*3.5.2 Inverter way*

The four primary components for producing electricity using solar power, which provides common 220volt AC power for daily use, are: Solar panels, charge controller, battery and inverter. Solar panels charge the battery, and the charge regulator as it will be shown in **Figure 7** ensures proper charging of the battery. The battery provides DC voltage to the inverter, and the inverter converts the DC voltage to normal AC voltage.

The design of modulated circuit shown below in **Figure 8** discuss that solar energy (direct current) can be used to turn on the load for continues six hours to

The load can work in another way .by converting the output direct current from the batteries to AC current using a DC/AC inverter .this current can operate imme-

diately without any modulating in circuit as shows bellow in **Figure 9**.
