Solar lights market seen reaching $14.2 billion by 2031

The solar lights market is projected to grow from $8.1 billion in 2021 to $14.2 billion by 2031, driven by renewable energy adoption, smart infrastructure spending and off-grid demand. The outlook points to the strongest momentum in solar street lighting, outdoor LED products and remote electrification markets across Asia-Pacific, North America and Europe.

Why it matters: - Solar lighting is moving from a niche clean-tech product to a mainstream infrastructure option for roads, parks, campuses, industrial sites and remote communities. - The market’s projected rise to $14.2 billion by 2031 signals growing demand for lower-carbon lighting that can cut electricity costs and reduce dependence on grid power. - Governments, businesses and consumers are all expanding adoption as sustainability targets and energy efficiency goals intensify.

What happened: - Industry estimates put the solar lights market at $8.1 billion in 2021. - The market is projected to reach $14.2 billion by 2031, reflecting a 6.2% compound annual growth rate during the forecast period. - Allied Market Research released the outlook on June 11, 2026. - The report highlights rising adoption of solar street lights, solar garden lights, solar pathway lights, solar floodlights, solar security lights, solar shed lights and off-grid lighting systems. - A downloadable PDF brochure accompanies the report.

The details: - Solar lights use photovoltaic panels to capture sunlight, store energy in batteries and power nighttime illumination. - Efficiency gains in batteries, LEDs and solar panels have improved product reliability and lowered costs across residential, commercial, industrial and public infrastructure uses. - Modern systems now combine photovoltaic panels, rechargeable batteries, LED fixtures, controllers, sensors and smart monitoring tools. - Lithium-ion batteries, lithium iron phosphate batteries, smart motion sensors, adaptive brightness controls, IoT monitoring, wireless communication and AI-enabled predictive maintenance are among the core technologies shaping the category. - Public infrastructure projects increasingly use solar street lights to improve road safety while lowering municipal energy bills. - Solar lighting is spreading across highways, roads, parks, public transportation corridors, educational institutions, healthcare facilities and industrial zones. - Off-grid systems are especially important in rural communities, agricultural operations, mining sites and disaster-prone areas where utility access is limited or unreliable. - Solar street lights are now common on highways, pedestrian walkways, residential roads, parks and public spaces. - Outdoor solar LED products are gaining traction for decorative, security and functional lighting in gardens, pathways, campuses and commercial properties. - The report says smart city development is creating new demand as municipalities connect lighting with digital infrastructure and traffic management systems. - Manufacturers are also offering modular and customizable systems for highways, industrial facilities, commercial complexes, parks and residential communities. - The market faces two main hurdles: higher upfront installation costs and performance changes tied to weather and geography. - A second report link is available for purchase: Buy this report.

Between the lines: - The core growth story is not just solar power. It is the pairing of solar generation with smarter controls, better batteries and LED efficiency. - That mix makes solar lighting more practical for municipalities and businesses that want lower operating costs without sacrificing reliability. - The fastest adoption appears to be happening where grid access is weak, infrastructure spending is rising or governments are pushing clean-energy mandates. - Asia-Pacific stands out as the largest market and the fastest-growing region, which suggests manufacturing scale and public investment are reinforcing each other. - North America is benefiting from smart city spending, while Europe’s market is supported by strong regulation and environmental policy.

What’s next: - Continued declines in component costs and further gains in battery performance should expand adoption over the forecast period. - Smart lighting, IoT integration and AI-enabled maintenance are expected to create new product differentiation and service opportunities. - Governments are likely to keep specifying solar lighting in renewable energy, rural electrification and infrastructure modernization programs. - Regional demand should stay strong in the United States, Canada, the UK, Europe, India, Japan and emerging markets in Latin America, the Middle East and Africa. - Manufacturers are expected to keep expanding production capacity, automating operations and building distribution partnerships to meet rising demand.

The bottom line: - Solar lights are becoming a practical infrastructure category, not just a sustainability upgrade, and the next decade of growth will be driven by cheaper components, smarter systems and broader public deployment.
