May 15, 2026 — As the global energy transition accelerates, the "Dual Carbon" strategy takes deeper root, and national initiatives such as "Smart Cities" and "Rural Revitalization" gain momentum, solar garden streetlights—serving as a quintessential vehicle for the integration of distributed photovoltaics and green lighting—are shedding their traditional singular role as mere decorative fixtures. Instead, they are rapidly evolving toward greater efficiency, intelligence, and diversification. Consequently, the industry as a whole is entering a golden era of high-quality development, characterized by a continuously expanding market scale, a steady stream of technological innovations, and increasingly evident synergistic development across the entire industrial chain.
Market data indicates that the global solar lighting market is maintaining a robust growth trajectory, with solar garden streetlights—a core sub-segment—contributing significant growth momentum. According to statistics from Stratistics MRC, the global solar lighting market reached a size of US$11.1 billion in 2025; it is projected to climb to US$19.27 billion by 2032, representing a Compound Annual Growth Rate (CAGR) of 8.2%. Thanks to their widespread application in settings ranging from residential courtyards and municipal landscaping to cultural and tourism sites, solar garden streetlights have emerged as a pivotal force driving this market expansion. As the world's largest consumer of photovoltaic technology and exporter of lighting products, China is witnessing even more vigorous industry growth. In 2025, the domestic market for solar LED garden lights reached approximately RMB 7.2 billion; this figure is expected to surpass RMB 9 billion in 2026, with the Yangtze River Delta, the Pearl River Delta, and the Chengdu-Chongqing urban cluster emerging as the regions with the most intense demand.
In terms of regional distribution, the domestic market exhibits distinct tiered characteristics. East China leads the pack with a 31.5% market share, leveraging its robust manufacturing infrastructure and the "Beautiful Countryside" initiative to achieve large-scale deployment. North China accounts for 19.8% of the market share, bolstered by abundant solar resources and supportive "coal-to-electricity" conversion policies. Southwest China, driven by targeted fiscal support from the central government, boasts a growth rate as high as 27.6%, establishing itself as a new engine for industry expansion. Meanwhile, Northwest China has achieved high coverage rates in off-grid pastoral areas, thereby further broadening the scope of product application. In the international market, demand from emerging economies—such as those in Southeast Asia and Africa—is surging rapidly. Furthermore, policy initiatives such as the EU’s "Green Deal," the U.S. "Inflation Reduction Act," and Japan’s "Zero Energy Housing (ZEH) Subsidy Program" are further accelerating the global adoption and market penetration of solar-powered garden streetlights, thereby opening up vast opportunities for the industry's international expansion.
The sustained release of policy dividends is laying a solid foundation for the industry's growth. At the domestic level, the "14th Five-Year Plan" explicitly designates distributed photovoltaics and smart lighting as key priorities for development. Policy documents—such as the *14th Five-Year Plan for Renewable Energy Development* and the *Action Plan for Green Building Development*—continue to reinforce support for photovoltaic lighting products, mandating that green energy products account for no less than 30% of the lighting systems installed in newly developed public green spaces. Various regions across China—including Guangdong, Zhejiang, and Jiangsu—have successively introduced local subsidy policies; these initiatives offer financial grants or tax incentives ranging from 15% to 30% for public projects that incorporate solar LED lighting, thereby significantly lowering the initial investment threshold for such projects. Concurrently, the new national standard GB/T38595-2025 establishes—for the first time—mandatory requirements regarding the availability rate, rainy-day autonomy, and IP66 protection rating of solar lighting systems. It also introduces a three-tier energy efficiency labeling system to promote standardized industry development; currently, products classified as Level 1 energy efficiency account for 37.6% of the market share. On a global scale, 47 countries have already incorporated solar lighting into their mandatory infrastructure standards. Furthermore, the World Bank’s "Lighting Africa" initiative has pledged to allocate $1.8 billion in dedicated funding by 2025, with a specific focus on supporting the installation of solar streetlights across Sub-Saharan Africa.
Technological innovation and iterative upgrades have emerged as the core drivers of the industry's high-quality development, with significant breakthroughs achieved across three key domains: photovoltaics, energy storage, and intelligent control systems. In the realm of photovoltaic modules, high-efficiency monocrystalline silicon modules have become the market mainstream, typically achieving conversion efficiencies ranging from 18% to 23%. Certain high-efficiency monocrystalline PERC modules have even surpassed the 23% mark in laboratory testing. Additionally, novel photovoltaic technologies—such as perovskites—have made substantial strides, achieving laboratory conversion efficiencies exceeding 25%; their inherent flexibility and bendable properties offer expanded possibilities for product design and aesthetics, while transparent photovoltaic modules enable the seamless integration of "lighting + power generation," thereby effectively meeting the diverse requirements of urban landscape environments. In the realm of energy storage systems, lithium iron phosphate (LiFePO4) batteries are gradually displacing traditional lead-acid batteries. These advanced batteries boast a cycle life exceeding 3,000 cycles, a charge-discharge efficiency of 92%–95%, and a monthly self-discharge rate of less than 3%. Furthermore, they maintain over 80% of their capacity output across a wide temperature range spanning from -20°C to 60°C. Certain manufacturers have even introduced solid-state batteries that extend the cycle life to over 5,000 cycles, thereby completely resolving the critical issues—such as electrolyte leakage and short lifespans—that have long plagued traditional energy storage batteries.
