Abstract

This paper presents a method for analyzing the relationship between solar power and rated load to use as a database for the installation of stand-alone PV system. The analysis is divided into 3 cases; need to know the rated of the solar cell for installation when the user knows the size of the load and the duration of use, need to know the maximum load size when the user knows the rated of the solar cell and the duration of use, and need to know the duration of use when the user knows the rated of the solar cell and the size of the load. The results of experiments to produce solar cell power at 50 watts, 100 watts, 150 watts and 200 watts in one day can be written in the form of the equation of a parabola and it is transformed into the equation for determining the rated load. This equation was tested for all three cases to verify the accuracy that the results have the average error of 8.25%, 4.01% and 5.09%, respectively.
