Rancang Bangun Sistem Monitoring Online Parameter Panel Surya Berbasis IoT

Abstract

Solar panels are devices that are able to convert solar energy into electrical energy. The use of solar panels in Indonesia is very beneficial because Indonesia is a tropical country that has energy potential with an average daily insulation of 4,5 - 4,8 kWh/m2/day. To be able to maximize the use of solar panels, it is necessary to monitor solar panel parameter online, so that data could be easily accessed through the internet network. To create an online monitoring system, an internet of things ESP8266 NodeMCU V3 device is needed as a controller and connecting device to the internet network, so the data that the tool reads can be displayed on web pages and android. The current and voltage from the solar panel that passes through the solar charge controller is read by the INA219 sensor which is connected to ESP8266 NodeMCU V3. Furthermore ESP8266 NodeMCU V3 is connected to the internet network, and sends current, voltage and power data to the server, so that data could be displayed on web pages and android. Data displayed on web pages is current in units of milliamperes, voltage in units of volts and power in units of watts, with the update rate of 1 second.
