China: BIPV Photovoltaic Footpaths Light Up Zero-Carbon Industrial Parks
In China’s Jiangsu Province, solar walkways have taken a significant step forward. In August 2024, New Sunshine Smart Solar planned a new BIPV application scenario at the Xifu River Green Low-Carbon Science and Technology Innovation Park in Yancheng – a footpath paved with photovoltaic power-generating floor tiles. The PV footpath covers a total area of 416 m², stretches 594 meters in length, has an installed capacity of about 5.6 kW, and generates up to 5,610 kWh of electricity annually. The surface layer consists of high-strength tempered anti-slip glass, with a maximum load capacity of 80 kg/cm², sufficient for pedestrian and even light vehicle traffic, ensuring walking safety. Designers left a 20 mm gap between modules for embedded LED light strips, achieving energy-saving daytime power generation and nighttime illumination, turning the path into a scenic riverside feature in the park.
In local livelihood projects, solar lighting technology has also played a key role. In November 2024, Jingyang Village, Langxia Town, Jinshan District, Shanghai, completed installation of 84 solar streetlights covering nearly 2 kilometers of three village-level main roads, benefiting 121 households. Previously, the roads were poorly lit at night due to dense, tall trees, posing safety risks. The village committee raised 300,000 yuan and, with support from an honorary village director, successfully completed the lighting project, greatly improving safe travel for residents. In October 2024, nearly 30 “diamond‑shaped” solar streetlights were installed on a riverside pedestrian boardwalk along the Luohe River in Yiling District, Yichang, Hubei Province. Because this section lacked pre‑wired electrical lines and lamp posts, solar lighting proved an ideal solution, combining environmental protection with excellent illumination through dual light‑and‑time control.
Global Perspective: Projects Advance in Australia and North America
In 2024, solar access walkway construction accelerated not only in China but also globally, with significant growth seen in Australia and North America.
In Orange, New South Wales (Australia) , the city council announced in June 2024 that it would add solar lighting to a newly completed walking and cycling path in South Orange. The project includes installation of eight 1‑meter‑high solar bollard lights covering a 100‑meter section. Funded by the NSW Government’s “NSW Get Active Program” with a total of A15,000 is for lighting), the bollard lights provide 360‑degree coverage and a 5‑10‑meter lighting radius, greatly enhancing nighttime safety, according to Cr Jack Evans, Chair of Orange City Council’s Infrastructure Committee. He noted that this is an important step in building an active transport network connecting the entire city.
In Katherine, Northern Territory, the local council launched a solar lighting installation project along the River Link Trail in March 2024, installing a total of 32 solar lights. Funded by the Northern Territory government’s “Safer Territories” initiative, the project aimed to address anti‑social behavior in public spaces. Temporary trail closures were implemented during construction, reflecting the community’s strong emphasis on public safety. Mayor Lis Clark stated: “We are using this funding to promote solar lighting projects across the town to light up previously dark walkways.”
In North America, several notable projects have emerged. In Port Alberni, British Columbia (Canada) , a 4‑km Quay to Quay multi‑use trail opened to the public in September 2024, featuring 56 Sol UP2 solar lighting systems. Each system has dual solar panels to maximize energy collection and uses nickel‑metal hydride (NiMH) batteries to withstand cold climates. The lights are also equipped with motion sensors that increase brightness when activity is detected, optimizing energy use. In Vestavia Hills, Alabama (USA) , the city plans to install four solar lights and corresponding sidewalks along Oakview Lane, with funding provided by the U.S. Department of Energy.
Technological Innovation: Solar Canopy Walkways and Smart City Applications
In 2024, the concept of solar access walkways expanded beyond paths themselves to include canopy coverings, rooftop maintenance access ways, and smart city interactive installations.
Tallahassee Community College in Florida, USA, began a $1.5 million project in March 2024 to install solar‑canopied walkways covering nearly 8,000 feet of main campus corridors, extending from the bus loop to the Science & Mathematics Building and other areas. These solar canopies not only provide shelter from sun and rain for students and staff but also feed collected energy back into the grid, reducing the college’s operating costs. Barbara Wells, Vice President for Administrative Services, said: “The solar walkway is an important part of our ongoing commitment to sustainability.”
In the field of solar system maintenance and safety, “Solar Access Walkway” products have become a key growth area. Dedicated rooftop solar maintenance walkways gained attention in 2024. These systems provide safe, anti‑slip access routes for PV arrays, making routine cleaning, inspection, and repair easier, while preventing damage to roof surfaces and solar panels. Manufactured from high‑quality materials such as zinc‑aluminum‑magnesium‑coated steel (ZAM steel) or fiber‑reinforced polymer (FRP), these walkways offer excellent corrosion resistance and durability, meet stringent workplace safety standards, and significantly reduce long‑term maintenance costs.
Furthermore, solar access walkways have evolved toward smart city interactivity. For example, some products are designed as intelligent solar floor modules that can be programmed to display energy consumption data, pedestrian traffic, or provide additional illumination. Such walkways can be installed in outdoor public spaces like railway stations, shopping centers, parking lots, and parks, closely integrating green energy with urban technology.
The “PV + highway” model has also gained attention in China. In March 2024, Sichuan Province released its “Green Self‑Power Supply Project Plan for Expressways (2024‑2025),” proposing 36 PV‑integrated expressways. Additionally, China’s first zero‑carbon desert highway has been successfully operated. In Henan Province, a distributed PV system at the Guandu Yellow River Bridge service area on National Highway 107 was grid‑connected, becoming the first integrated transportation‑energy project on an ordinary highway in the province.
Market Prospects and Challenges Coexist
The market potential for solar access walkways is enormous. According to a recent global strategic business report, the worldwide solar roadway market was valued at US985.6 million by 2030, growing at a compound annual growth rate (CAGR) of 24.1%. This data strongly indicates that as an innovative green infrastructure solution, solar access walkways are gaining increasing global recognition and adoption.
However, the field faces technical challenges. Despite their potential, the practical utility and cost‑effectiveness of solar walkways must withstand real‑world scrutiny. For example, a €70,000 “solar pavement” project in Rabat, Malta, claimed an annual power output of 4,600 kWh, but actual data showed that since its completion in 2021, it has generated only 2,343 kWh — just 22% of the claimed value. This case highlights that the engineering, durability, and power generation efficiency of solar walkway technology still require further validation and improvement. In contrast, China’s BIPV photovoltaic footpath project, using high‑strength tempered anti‑slip glass and customized module design, has achieved a better balance between pedestrian safety and generation efficiency.
As solar technology continues to mature and innovate, solar access walkways will play an increasingly important role in the global green transformation of urban infrastructure. They are not just functional energy‑generating facilities, but comprehensive public spaces that enhance urban resilience, beautify environments, and foster community interaction. This bright path toward a zero‑carbon future is quietly extending beneath our feet.
