Abstract
Interest in photovoltaic systems, as a clean and infinite source of energy, has increased in the past decade. Researchers are constantly trying to come up with high efficiency and low cost photovoltaic (PV) modules. A solar panel is the fundamental energy component of PV systems. The PV modules have maximum power operating points depending on the intensity of sunlight, temperature of the solar panels, cell area and load. When solar power is the energy source, the output power has to be maximized by increasing the efficiency of the power conditioning equipment. This is achieved by implementing an adaptive power controller that automatically tracks the system to the point of maximum power delivered by the solar panel at all times
