Solar energy is the fastest growing renewable source of energy (40% increase p.a. worldwide). The sunrays hit the solar panel surface and the photons present in sunlight create a photoelectric effect and hence generate electricity. The tilt angle for the solar panel is dependent on the latitude of the place. Solar energy is trough out the year and solar power plants need to be monitored for optimum power output, which can be, efficiently and effectively done with the use of IoT. The poster studies cases for small scale (household solar panels) and large scale (industrial solar plants). The general requirements, process, and implementation are also explored.
