At present, the great value that is reaching renewable energy is known. The aim of the Kyoto Protocol is to reduce CO2 emissions. Two great benefits will be reached: energy independence and reduction in the risk of the future escalation of energy costs [1]. Photovoltaic energy will create an increasing contribution to electrical power supply all over the world. This work will analyse in depth the algorithms Perturb and Observe (P&O) [2], [3], [4], Incremental Conductance (Inc) [2], [3], [4] and Constant Voltage (CV) [2], [5] with some changes proposed (for example an approximation of the Incremental Conductance is mixed with the Constant Voltage getting a more robust structure). Also the Newton Raphson (NR) algorithm will be analysed based in the numerical method of Newton Raphson (fast convergence and goodness to gain non linear equation make one of the best).
