The increase in the installation of solar street lights in the world is a clear indication that the new renewable energy comes packaged with loads of advantages. Many choose solar energy technologies because they reduce costs and energy consumption and improve the utilization efficiency of energy. When considering solar energy in street lighting, many people only think in terms of the components they see. Experts will tell you that there is more in the solar energy system than just parts. Technically you will need to design a Solar Street Light Circuit Diagram to determine the flow of electricity from the source to the specific components.
A Solar Street Light circuit diagram gives a schematic flow of electricity coming from the solar panels, passing through the controller, battery, and ending at the light source. In areas where the solar street lights operate during the day, the
A typical Solar Street Light Circuit Diagram should contain:
- Solar panel – the source of electrical energy
- Charge controller – controls the battery charging process
- Battery – stores electric energy
- Light Dependent Resistor (LDR)- also photoresistor or photoconductor
- Light Emitting Device (LED) Bank – the source of light
- A switch
- Voltage regulator
- Interconnecting cables
In general, the whole circuit diagram comprises of three circuits: the switching, solar charging, and lamp light circuit.
A typical stand-alone solar street light does not need a transmission line, routing the cables or any unique management or control system. Independent street light has a different circuit diagram from ones that share the same solar energy source.
The solar street light circuit diagram is available in two forms depending on the audience. There is the schematic and the graphic style which uses industry-standard symbols and basic images, respectively. You will need to be an electrician or someone with supporting knowledge of the subject to understand a schematic style circuit diagram.
Below are some of the circuit diagram symbols:
- The Ammeter symbols.
- The Voltmeter symbols.
- The resistor symbols.
- The switch symbols.
- The battery symbols
- The Transistor symbols
- The capacitor symbols
- The light bulb symbols
- The solar cell symbols
- The fuse symbols
- The diode symbols
The Use of a Solar street light circuit diagram
- Visualization and understanding
In the design of the actual light circuit, Electricians and engineers first use circuit diagrams to gain an understanding of how electricity flows in the equipment. Technically, they are used in circuit design and PCB layout. Computer scientists rely on these diagrams to easily visualize expressions using Boolean algebra.
Circuit diagrams are used to show the different type of components and how they are connected together. Using the symbols only is not enough, you will need a layout that has been calibrated with crucial parameters such as the volts, resistance, current, and labels for more than one component.
Someone with limited knowledge in solar technology may find it easy depicting the physical arrangement of the wires and how the components connect using physical design, artwork or layout and wiring diagrams. From a technical point of view, a circuit diagram would be required to understand how electricity flows in the connection and determine the maintenance of the solar street light.
A solar street light circuit diagram will show you the number of each component, their ratings, and the type of connection (series or parallel). Besides identifying the most economical and effective solution for your lighting needs, it will also help you monitor your costs.
- Safety of machinery
A solar street light circuit diagram will help you determine the safety of the equipment. An electrician would use this diagram to consider modification and reduce nuisance that can be modified. For instance, one might eliminate the need for DC-to-AC conversion or vice versa by using power from the battery directly.
- Improve the productivity of the solar street light
With the use of a solar street light circuit diagram, an electrician can make specific improvements to enhance the productivity of the equipment. For instance, if you wish to introduce a wireless control system or sensor technology to your solar street light, the technician will use the circuit diagram to determine if the modification can be supported.
A circuit diagram is an important document when there is an electrical problem with the system. This is the only language electricians, and solar experts know when it comes to repair and maintenance. The circuit offers crucial specifications of power requirement of the various components so that the right one can be used.
An improved circuit diagram eliminates loss of power associated with the efficiency of the inverters.
- Efficient and effective Installation
A simple circuit diagram should help you visualize the precise placement of components in your solar street light. A circuit diagram is a crucial component in the installation of solar street lights. All wires and parts need to be connected according to the electrical circuit diagram to avoid accidents and damages.
You will need some calculations on your side to determine the voltage (DC or AC) and current that is required to sustain the street light for the number of hours you need. You will also need to determine the total load of the circuit. This will help you increase the efficiency of your solar street light. To complete the Solar Street Light Circuit Diagram, you will need to determine the nominal voltage. This type of voltage is obtained from the number of battery cells to be charged.
The way you connect your components or do the wiring can affect the efficiency of your solar street lights. With the use of a circuit diagram, your installation will be easy and with fewer risks. In an automatic street light adjusting the variable resistor value can help you circuit switch on and off the light at your set lighting intensity.
Therefore, a solar street light circuit diagram will help you in the modification of your device. It will define the type of battery or light bulb to be used to power the whole circuit. Using this diagram, you can determine the cost of your modification and the implications.
