The use of of single power solar system in generation of electricity for streetlights nowdays is widely used. Generally, many of this kind of streetlight is using one solar panel system to power its lamp. The problem that can be arise for this kind of streetlight is how to control and guarantee the optimal system [1]. The use of ACS712 current sensor and voltage sensor using voltage divider circuit with GSM communication system allows to monitor [2] both the battery and the solar panel. The information from the current sensor and voltage sensor then processed by a microcontroller. This microcontroller then send the data through a GSM communication system to a server, via short message service (SMS). This server then processed the data by parsing the information from the SMS, and send the data to a web server database. This information then can be accessed by internet. The expected outcome of this monitoring system is a system that can be used in monitoring small solar power plants system as the street lights.
