This paper will discuss about the design of a portable photo voltaic electric generator capable of tracking sunlight in all directions. Such power generator is designed for disaster affected area with power outage, such as during major floods like Jakarta in 2012, or strong earthquake such as Yogyakarta in 2006 and Japan in 2011 (Tohoku) and 2016 (Kumamoto). Such occurrence usually results in disruptions of public service, especially power grids. The system prototype consists of a 10W solar panels capable in two axes movement, which is 120° horizontal and 360° azimuth movement with ATMega8535 micro controller as the main controller. Two-axis movement is based on two types of sensors; 360° directional movements is based on the HMC5883 compass sensor. This compass sensor panel also be configured to always directs towards the sun so that if the direction of the base plate was changed, it will automatically direct the panel to the direction of the sun. While 120° vertical movement based on three pieces of LDR (Light Dependent Resistor) as sun sensors. The purpose of this system is to maximize the amount of light received by the panel so the panel power output is also maximized so it can generate emergency electrical supply for lighting and other basic needs.
