Increased road infrastructure development projects in several countries as a result of rising vehicular traffic is another key factor driving global demand for solar street lighting devices. Because of rising urbanization and road traffic, many countries, including India, Germany, the United States, and China, are launching massive roadway and highway development projects. “Global sales of commercial vehicles increased by 2.2 percent in 2019.” Furthermore, “global sales of these vehicles reached 26.9 million units in 2019.”

Aside from the aforementioned factors, “the growing number of smart cities is also significantly contributing to the soaring sales of solar street lighting systems around the world.” Over the last few years, there has been a significant increase in the construction of smart cities in countries such as the United States, India, Saudi Arabia, China, and South Korea, and this trend is expected to continue in the coming years. Furthermore, many countries’ governments are making large investments in the development of smart cities, which is increasing sales of solar street lighting devices.

Because of the aforementioned factors, the global solar street lighting market’s valuation will rise from $5.7 billion to $14.6 billion between 2019 and 2030. Furthermore, the market will grow at a CAGR of 9.4 percent between 2020 and 2030, according to the publisher, an Indian market research firm. Solar street lighting systems are commonly used on airport runways, parks and playgrounds, manufacturing sites, parking lots, and roadways and highways. Among these, the use of these lights in roadways and highways will be the greatest in the coming years.
