Due to growing energy costs, decreasing photovoltaic panels and storage prices, and the advent of new green energy technology, solar street lights have become a more popular choice for lighting up public spaces. This makes the power street lights an effective and reliable solution. In this post, we will compare regular street lights and powered by solar LED street poles/lights to better comprehend all of the advantages of solar powered LED street lights.
Primarily facility and project managers are most concerned with finding new ways to decrease energy and maintenance expenses to the bare minimum. Solar-powered LED street lamps could be an excellent solution for this. Not only as a source of light, but also as a source of clean energy.
What is the difference between solar and traditional street lighting?
Solar street lighting solutions require the use of grid electricity. They are entirely energy autonomous and are not linked to the electrical grid network. Throughout the day, photovoltaic systems or solar panels collect light and transform it to electricity, which is then saved in a battery pack.
The charge controller is the brains of the sun lighting systems, controlling battery storage space, solar charging power, and ensuring the overall solar lighting system has a longer life span. The stored energy is often used to operate LED lighting during the night.
Conventional street lights (high pressure sodium or metal halide) are powered by the normal electrical grid, which is powered by fossil energy (non-renewable) resources.

Because they use renewable sources of energy that are both safe and excellent for the environment, photovoltaic systems LED street lights/poles have a very low environmental impact. Every day, the solar lighting system generates energy from the sun and emits no damaging CO2.
Lighting Efficiency
Solar-powered LED street lamps and poles employ the most up-to-date LED technology, which produces strong light with more lumens while using less energy. Conventional street lamps have a lifetime of 10,000-15,000 hours and a far greater rate of failure than LED lights, which have a lifetime of much more than 80,000 hours.
High Pressure sodium or metal halide lamps have lower colour rendering indexes, whereas LED lights could be coloured to suit almost any CRI, have superior visibility, and come in a variety of distribution patterns.
Cost over a lifetime
When comparing the purchasing price of off-grid solar LED street lights to standard street lamps, the first expenditure is often two times more. Conventional street light installations, upkeep, and electricity costs per unit vary from 7,000-10,000 USD across an 8-year span, but the cost of solar driven roadway powered LED light/poles is anticipated to be 3,500-5,000 USD during the same time period.
Cost of Installation
Conventional street lights need cabling and subsurface trench digging to link to grid lines, which adds significant costs to new installs in remote regions, whereas solar powered LED street lamps are significantly easier to install. All that is required is the construction of a concrete base and the installation of a solar pole. Overall, the installation time for one solar pole and less than an hour
