Automatic Movable Solar Lamp for Continuous Charging
In today’s climate of growing energy needs and increasing environmental concern, alternatives to the use of non-renewable and polluting fossil fuels have to be investigated. One such alternative is solar energy. Solar panels consists of photovoltaic cells, converts the solar energy into electrical energy and this electrical energy is stored into a battery. The system designed here is very useful for gardens, where huge trees exist. In such places availability of solar energy may be difficult due to the shadow of trees; therefore solar lamp posts may not function properly. To overcome this problem, here in this project work, an automatic movable solar lamp post is designed that tracks the sun automatically during day time and shuts down during night. It also activates the lamp automatically during night and switches off during day time. The proposed project work is designed to detect the presence of the sun and can position the solar panel towards sun’s direction automatically, i.e., the system rotates the panel automatically according to the sun position, so that maximum solar power can be utilized. Provision is made in this system, so that during daytime, if the sky is clouded and the panel is not receiving any sunlight, then the system itself will be switched off automatically, by which precious energy of the sun, which is stored in the rechargeable battery can be saved. When the clouds are cleared, system energizes automatically and drives the panel towards the direction of sun
