This paper presents analysis and control of D converter, which has continuous input and output current to obtain maximum power transfer from a photovoltaic (PV) system. Examining the maximum power involves optimization and control techniques that ensure maximum power extraction enhancement. Traditional converters have rather high input ripple current that originates considerable loss of power extraction...
For grid-connected photovoltaic system, performance monitoring plays an important role in ensuring efficient power delivery. Performance monitoring is needed to observe the system and provide counter measures should any failure occurs. This paper outlined the monitoring insights on grid-connected photovoltaic systems in terms of data communication methods used as well as the important characteristics...
We report the synthesis and characterization of DSSCs based on N719 dye and ZnO nanorods. The nanorods were synthesized on fluorine doped tin oxide coated glass (FTO) substrate via chemical bath deposition method at 85 °C using zinc nitrate hexahydrate and hexamethylenetetramine. Prior to nanorods deposition, the substrates were coated with ZnO seed layer by spray pyrolysis technique. Our ZnO nanorods...
In this paper a low cost microcontroller-based solar battery charging system with Maximum Power Point Tracking (MPPT) features is presented using 220 Watt solar panel as power source and buck converter as power converter. PIC18F4550 is used as the main controller to realize the system to charge 12V battery with 80Ah capacity. Experimental results shows that throughout charging process, charging voltage...
