Solar energy can not be directly utilized directly, to utilize solar energy into electrical energy, still needed equipment such as solar cell (solar cell) to convert solar energy into electrical energy that will be used to turn on the light automatically by using ldr sensor as its automatic tool . With the problem, the authors have made solar panels that serve as pensuply electric current.In making the author using the charger controller so batreai not easily damaged. The result of this research is the power generated from the total output power required on the lamp is 0.2429 watt, and the energy generated in the period of 8 hours is 1,943 watts. So to run this terrace lamp automatically for 8 hours it takes 1 battery 12v 100 Ah and 1 solar cell with 100wp (peak wattage) capacity.idTeknik ElektroTeknik ElektronikaCell SolarCharger ControllerThesis
