An IoT Solar Lamp With PV System

This research paper aims to increase the efficiency of electric usage via IoT technology. An Solar Lamp is a system that use solar energy as alternative green reduce AC power line consumption from our national grid (PLN). There has been some successful product such this one (e.g. branded Sonoff switch), but it not used PV main source energy. Therefore unique because promotes in household application. remote controlled lamp 2 pieces solid-state relay choose electricity supplies, either or battery. The battery will be charged by 50Wp panel and uses NodeMCU-ESP8266 connectivity internet, users can voltage supply turn on off, with smartphone. result study shows powered 12Volt-18Ah for approximately 3 hours.
