The high use of conventional resources in electricity production and the fact that these resources diminish with every passing day have increased the studies carried out on renewable energy sources. However, the use of renewable energy sources in the most efficient way possible is one of the topics that come to the foreground. The fact that LED technology is used in the illumination systems provides energy saving. In this study, the DC electric energy that is obtained from PV (Photovoltaic) panels is accumulated in battery groups, sensitive to illumination intensity and motion taken from an ambient of light sensor, a proposed algorithm that controls the light level of LED which are in DC (Direct Current) characters. In comparison with normal LED illumination systems, 50.6% energy saving has been attained.
