This paper describes some fundamentals about Photovoltaic (PV) Systems and also studies many aspects related to the control of the efficiency of PV arrays directly coupled to a DC load. PV arrays has some intrinsic characteristics that can affect its output power during different operating conditions. Hence, PV arrays output power is usually maintained relatively constant by using control algorithms. The Perturb and Observe (P&O) algorithm is one of this control algorithms which is studied in the present paper. Additionally, it is also analyzed the faults of the P&O algorithm in maintaining stable the efficiency of the array with rapid variable ambient conditions. In that sense, it is stated the possibility of investigating some modified P&O algorithms that can be found in the literature in order to improve the results of the P&O algorithm with respect to its effectiveness to control the efficiency of the array and its ease of implementation in a PV system.
