Maximum Utilisation of Solar Energy for Smart Home Lighting System

In modern world there is burgeoning demand for energy to power every piece of technology. Due to this, the non- renewable energy resources are reaching the point of depletion sooner than expected. Thus, researchers around the globe are searching for an alternative of fossil fuel and trying to find a sustaining energy source. There has been many recent development and innovation in the field of solar energy utilization. In this paper, a method has been proposed for the maximum utilization of solar energy for home lighting applications. Firstly, sun tracking solar panels are to be used for harnessing as much solar energy as possible. This assures the maximum solar power gets stored in the Photovoltaic (PV) cell. The PV cell gives DC output which can be stored in a battery, preferably lithium polymer battery and can be used to power home lighting appliances. The rest can be stored in solar UPS for future usage or power other AC appliances. Furthermore, the solar UPS helps convert the house from hybrid to off-grid solar system. Finally, the charge stored in DC battery are used to vary intensity and color of RGB LEDs. The rooms can be illuminated as required by the user. These series of methods or control systems helps to conserve and maximize the utilization of solar energy.
