This paper presents the results of an achieved designed method for an optimum combination of a hybrid power system (HPS) based on photovoltaic, battery and liquefied petroleum gas genset (PV/BAT/LPG) in remote telecommunications equipment. From the various forms of feeding such equipment independently to the public grid, a solution is proposed that combines two redundant sources (one of them renewable energy) procured to widen the availability with respect to PV and LPG stand-alone systems. Then, this hybrid system can guarantee the certainty of meeting load demands at all times at reasonable cost, for certain latitudes and escapes of the total dependency of the resources of the hydrocarbons and the economic viability of some other energetic alternatives. As an example for Braunschweig (Germany) the best combination reduces by 55% the total cost compared to PV stand-alone. In this way, hybrid power systems are oriented to be deployed in remote areas, outside of the central office, where utility lines are uneconomical to install due to terrain or environmental concerns
