| Abstract [eng] |
As the Maximum Power Point Tracking (MPPT) of a photovoltaic (PV) cell changes with respect to the atmospheric condition, it plays an important role in solar power generation system. A Smart Solar Panel System has been developed, consisting of the dual axis tracking unit which uses the time, date and geographical co-ordinates to find out the horizontal and azimuth angle of sun. This data is used to point the solar panel to orient itself for receiving maximum irradiance. These factors are also included for tracking maximum power. MPPT technique is dependent on Vph and Iph. MPPT is used in PV systems to maximize the photovoltaic array output power, irrespective of the temperature and irradiation conditions and of the load electrical characteristics. This paper introduces a panel tracker to get the maximum irradiance from the sun depending upon light condition. PV generators exhibit nonlinear I-V characteristics and Maximum Power Point that vary with solar isolation. An intermediate DC- DC converter can therefore increase efficiency by matching the PV system to the load and by operating the solar cell arrays at their Maximum Power Point. The Maximum Power Point tracking with DC-DC converter extracts the maximum power from the panel to the local storage. Applied for stay back In this paper, Smart Solar Panel System is described which uses Maximum Power Point Tracking process, dP/dV feedback method algorithm using the measurement of Array voltage (Vpv) and Array current (Ipv) and is verified by simulating in Matlab Simulink. |
