the idea of this project is to use solar PV system to run a light system. having 1 solar panel for 120 watt and 7 LED's each consume 20 watt, ( total 140 watt) the goal is o run the light system and monitor it through wi-fi ( ON/OFF and light intensity) when there is overload the relay will make a switch to the grid.
i will upload power point to clear the idea
