The schematic diagram of a solar street light system can help visualize how the different parts of the system are interconnected. The diagram typically includes symbols that represent the components associated with the system.
The document describes a project report for a solar powered LED street light with automatic intensity control. It includes a functional block diagram and explanations of the components, including a solar panel, charge controller circuit, rechargeable battery, voltage divider circuit, and Arduino UNO microcontroller.
A typical solar street light system consists of several different parts, including a solar panel, an energy storage battery, a power conversion system, and the streetlight itself. The solar panel collects energy from the sun and converts it into DC or direct current electricity.
Oke et al10 designed and constructed a solar powered lighting system. It stated that solar energy is harnessed for powering street light and almost 100% operation of the system is achieve without the involvement of manual operation for ON and OFF switching of the light whenever the sunlight comes or goes using Light Dependent Resistor (LDR).
Solar Energy and Application in Street Light: Solar panels consist of photovoltaic (PV) cells that are either serially connected or in parallel. It is a large area semiconductor p-n diode having its junction placed near the top of the surface4.
Referring to the 40 watt street light circuit diagram above, the panel voltage is regulated and stabilized to the required 14.4 volts by the IC LM 338. P3 is used for setting the output voltage to exactly 14.3 volts or somewhere near to it.
