3Introduction to Solar Integrated SMART Street Lighting System
SMART Street Lighting System (solar integrated) utilizes street light controllers which are smarter versions of the mechanical or electronic timers previously used for street light ON-OFF switching operation using the solar energy for it’s power.
They come with energy conservation options like twilight saving, staggering or dimming as they are designed primarily for energy efficiency.
A comprehensive system usually consists of: -
LED
Control unit
Sensors installed in each lamp pole or group of lamp poles
Communication units

5Solar power & it’s conversion to electricity
Solar power is the conversion of sunlight into electricity, directly using photovoltaic (PV). Solar Cells converts light into an electric current using the photovoltaic effect.

7Primary Electrical Components required for the setup
Solar Panel(12V,10Watt)
Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating.

8Primary Electrical Components required for the setup
Light Dependent Resistor (LDR) A light dependent resistor works on
the principle of Photo conductivity. Photo conductivity is an optical
phenomenon in which the materials conductivity reduces when light is absorbed by the material.

9Primary Electrical Components required for the setup
Battery (12V)o An electric battery is a
device consisting of one or more electrochemical cells with external connections provided to power electrical devices.
Transformer(230/12 V, 1Amp) o Electrical power transformer
is a static device which transforms electrical energy from one circuit to another without any direct electric connection and with the help of mutual induction

ConclusionThe following conclusions can be drawn after completion of the project: Solar integrated SMART street lighting system is one of the leading
innovations in the 21st century as it is not only eco-friendly but also more energy efficient.
Automatic controlling by LDR and its circuit leads to more energy conservation/lesser energy losses.
As the system is controlled by a controlling circuit including charge controller, 2-pole switch and 3-pole switch, the system is very protective, low maintenance cost and very useful.
As they are automatically controlled using LDR, dimming and brightening are the key points of the SMART street lights.
The governments of different countries should initiate this type of solar integrated projects to further promote a healthy environment for humans as it is pollution free. May 1, 2023

Future Scope The initial investment in solar LED street light system remains a
major problem. However, the efficiency of the solar cells is increasing, while the price is decreasing. At same time, the efficiency of the LED light is in a rapid increase, but the prices are lower. So following development of the outdoor lighting technique, the solar LED street light system has shown us that it will have promising applications and infinite vitality in future.
We can use AC lamps or lights instead of DC LED’s by using a inverter which is used for converting DC to AC voltage.
We can use dual axis solar tracker for efficient charging of battery from solar energy. It also helps to generate more power from solar means. If we want to increase the load this will be one of the most efficient methods.

Essentiality of Proteus in the Project
Proteus has helped us in the completion of the project technically in recreating the design of the circuit and simultaneously checking for errors in any kind of wirings and other important factors like voltage drops and led tests. Without Proteus it would’ve been impossible to design the overall circuit as any kind of errors can be pre-checked to be sure for the final design.
