摘要：The PV cells are used to convert incident solar energy into electrical energy. However, due to change in environmental conditions less power output is generated. The operating point shifts from the maximum power point (MPP) to some other point, which decreases the efficiency of solar panels. Till now, the maximum power is estimated or PV power output is considered from the present value of voltage and current or reference voltage is estimated by using the given irradiance and temperature values. But in the Modified algorithm of P&O MPPT presented in this paper uses the theoretical power values which is calculated by using the system model which can be generated by the given irradiance and temperature values. We compare the results of the Conventional P&O to the Modified P&O. For the comparison we have taken voltage ripple, current ripple, power ripple, and tracking efficiency as the parameters. The graphs and observations clearly showed that Modified P&O boosts the efficiency of the system.
