  The photovoltaic system uses the photovoltaic array as a source of electrical
power for the direct conversion of the sun radiation to direct current without
any environmental hazards. The main purpose of this research is to design a
converter with Maximum Power Point Tracker MPPT algorithm for any typical
application of soil humidity control. Using this setup the major energy from
the solar panel is used for the control of soil humidity. The design of the
converter with MPPT together with the soil humidity control logic is presented
in this paper. Experimental testing of the designed controller is implemented
and evaluated for performance under laboratory environment.
