The garden light is one of a public facility that serves to give illumination on each of the existing parks in the city. Most of the park lighting systems in Indonesia, the garden light outages are still handled manually by relying on information from the community to report via the command center or checking manually by patrol. In this study, we proposed, a system monitoring tool garden light solar cell that can be accessed through the website. Monitoring the performance of park lights with remotely and real-Time is one application of the smart city concept. Namely by facilitating the monitor process and automatic battery power check. The result of the existing problems in the field, monitoring tool designed garden light solar cell-based website using a microcontroller connected ESP8266 Node MCU internet network so that it is able to display voltage and current data on photovoltaics, batteries, and lights. Other functions of this tool to monitor the condition of the lamp flame or outages on Garden lights solar cell and know the layout of the existing garden light poles in the field. This research has been tested directly in public parks in the city of Surabaya, with the accuracy of updating information at 100% and the accuracy level of the battery at 98.78%.
