Things to keep in mind to design Solar Street Lighting System -Eco-Friendly Technologies

July 2, 2019 0 By Environment Go!

Now the world is going solar to meet the varied lighting needs of the residents and Governments
are also feeling the pulse. Whether it is about fixing the lighting system on the roads, streets,
highways or pathways, the technology in the solar is ready to keep the floats of the solar system
ready. Above all, solar energy is an environmental friendly energy source.
So, what are the different aspects of the solar street lighting system while designing it? But before
understanding the aspects let’s get into its basics:

The solar power system is one of the leading renewable sources of energy that uses solar PV
module that convert sunlight into electricity. The energy that is generated is stored or used directly,
provided into the grid line, conjectured with one or the other source of electricity or different
renewable energy source.
The solar-powered energy is the cleanest energy source best suited for residential, industrial, agricultural and even livestock.
Components used in Solar Street Light System

There are many components available which should be chosen according to your system type, site
locations, and applications. 
However, the main components are solar charge controller, solar panel, battery, inverter, pole, and LED light.
Features of the solar led street light system

PV Module: Its main function is to convert solar light into DC electricity
Battery: It stores solar energy and supplies it whenever there is demand
Load: These are additional electrical appliances that are connected to the solar PV systems like
lights, Wi-Fi, camera, etc.
Solar Charge Controller: It is used as a mechanism to regulate the voltage from the PV Panels and
prevents the battery from overcharging.
To design the system, follow the steps below

Find out the power consumption of the street lights
Before going for the designing part find the total power and energy consumption requirement of
LED lights and other parts, that is supplied by solar power, like Wi-Fi, camera, etc. Calculate the
consumption of solar system by calculating total watt-hours per day that are required from the PV
modules and for each component.
Calculate the size of the solar panel required
As different sizes of the solar panels generate different power, we have to find out the different
peak watt produced required. The peak watt depends on the size of the module and the climate.
You need to calculate the total peak watt rating that is required for PV modules. If more PV modules
are installed, you will get improved performance, if a smaller number of PV modules is used, the system might not work at all, when there are clouds and the life of the battery will also get shortened.
Battery size
Deep Cycle battery is highly recommended for the solar PV modules. These batteries are quickly
recharged and discharged every day and for years. The size of the battery should be big enough to
store sufficient energy for operating the appliances at night and during cloudy days.
Size of the Solar Charge Controller
Solar charge controller is selected that match the voltage of PV array and batteries and then find out
the type of the solar charge controller that you require. Always remember that the solar charge
array has capability to take care of the current from PV array.
Other things that you should keep in mind are

Type of Light Fixtures
• Lumens per Watt of the fixture
• Type of Lamping required
• Light distribution patterns
• B/U/G rating and dark sky requirements
• Fixture bracket arm
• Mounting height
Quantum of Light Required
Find out the area that needs to be illuminated like 2 lanes street etc
Calculate the lighting details like lighting on the street should be .3-foot candle with lighting
uniformity under 10:1.
Always remember not to mention the lighting requirement according to the equivalency as you can
land up in finding out many different interpretations. This is also a case with foot candle
specification as it is a quantified measurement of light.
Light Pole
Find the type of pole that is required like anchor base pole, direct burial, steel, aluminium, concrete,
etc. The pole must be heavy enough to support the weight and EPA of the particular solar power
lighting system.
With these designs and performance parameters if incorporated will help buyer attain high equality
solar power lighting system and that too at the appropriate price.
Summary: For installation of the solar street light system it needs to be designed and many
parameters framed. This article should help decipher to the important things that we should keep in mind for designing, like the components which are used, size of the battery and others.

I’ve noticed articles on solar led street light are particularly popular these days and solar street
lights are highly beneficial in terms of energy efficiency, environmental impact and saving money on electric bills.
