Concerns on the issues about lacking on non-renewable energy, solar energy are the best solution for electricity generation. Solar energy is a renewable energy resources which is the least polluting and most inexhaustible of all known energy resources. The energy resource which directly produced by the sun can be converted to electricity by using solar cell. The intention of this project is to design the simple software of system sizing for stand-alone photovoltaic system using Microsoft Excel. This system was build up to make it easier to calculate the number of module, battery, inverter, charge controller and also load because it involved many calculations to sizing it manually. The system designing using 11W load was successfully light up the bulb with duration in ranges 4 to 5 hours suitable with the expected time from the system design. This project also conducted several test such as open circuit voltage, short circuit current, charge controller as well as inverter test. This project was run the experiment for 1 complete cycle which the battery had used during discharging and charging it until full. During discharging, the load can sustain up to 4.5 hours and then the charge controller disconnect the system when the voltage battery is 11.10 V. the initial voltage during charging the battery is 11.92 V and the voltage of battery when it was fully charge is approximately 12.5 V.
