Implementation of Solar Power DC Distribution lighting system with Intelligent Controller

Abstract

Photovoltaic (PV) are basically DC power sources which are green power sources belongs to the study of renewable energy sources (RES). Many nations have started taking steps to meet the required electrical energy demands through different renewable resources to improve the local impact, as the standard of living is increased. One of the main dc distributions in lighting is Street lighting and is the infrastructure which should meet the consumer requirements, expansions, and growth. Countries may have more burdens if still using High Pressure Sodium (HPS) lamps for street lighting as they are of A.C. Nowadays, LED light technology becomes a candidate as it surpass the HPS lamp from both energy and money saving. In this paper a Hardware setup of solar lighting system is proposed and designed which consists of 250W panel output with 12 volt supply and 120 volt supply based on the load configuration and low voltage based loads like led lamp with number of sets to glow continuously for hours based on requirement and battery capacity. Nearly twenty times less than ac voltage is carried out and proportional to illumination requirement lighting loads are designed which reduces the power and energy consumption. Here, solar energy is collected with the aid of a solar panel and thus, a battery is charged with the help of a simple optimized charging controller. The generated solar energy is used to charge the battery and it is discharged by the load. A dc supply is given by the battery when solar power is not available. These devices can be used for small-scale lighting applications in remote areas that are far away from the power grid.
