Abstract
The increasing activity of the people at night makes the need for lighting sources also increase, especially in public places. One part that requires lighting is the Iringmulyo Metro village road. Roads are the main infrastructure that must be considered for their condition and use, if the road conditions are good for passage it will certainly reduce the level of accidents and crime, so village roads also need lighting. Public street lighting using solar energy is a cheap and economical alternative to use as a source of lighting electricity because it uses a free and unlimited source of energy from nature, namely solar energy. The Iringmulyo Metro village road lighting system uses a solar cell of 200 wp and a lamp load of 40 watts. When the weather is clear the battery can charge up to 720wh and can run a light load for up to 18 hours. If the solar panel is unable to receive light, the battery still has a power reserve of 240wh/6 hours. Lighting a solar street light using a 40 watt LED lamp produces an illumination of 4.58 lux. The power efficiency of the solar cell module panel is 14.5% determined by the tilt position of the solar cell panel and the intensity of sunlight. The higher the sunlight intensity, the higher the output efficiency of the solar cell module
