第15章 調査会社について・免責事項

Global Solar Roadway Market was valued at USD 1.4 billion in 2024 and is expected to reach USD 5.6 billion by 2030 with a CAGR of 25.6% through 2030. The global Solar Roadway Market is primarily driven by the growing focus on renewable energy and the urgent need to reduce carbon emissions. Governments across the world are increasingly investing in sustainable infrastructure to meet climate goals, and solar-integrated roads present a dual benefit-clean energy generation and modernized road systems. Technological advancements in photovoltaic materials and energy storage have improved the efficiency and durability of solar panels, making them more viable for roadway applications.

Additionally, the rise of smart cities and electric vehicles has increased the demand for innovative transportation infrastructure, with solar roadways supporting features like in-road EV charging, smart lighting, and real-time traffic management. Increasing urbanization, particularly in Asia-Pacific, coupled with large-scale government initiatives, is accelerating market growth. Furthermore, the ability of solar roads to support decentralized energy production enhances energy resilience and grid independence, especially in remote areas. While high initial costs and durability concerns remain challenges, ongoing R\&D and public-private partnerships are addressing these issues. Overall, the market is expected to grow steadily as countries adopt integrated, sustainable transport solutions that align with long-term environmental and energy efficiency targets.

Key Market Drivers

Transition Toward Renewable Energy and Carbon Neutrality

One of the primary drivers of the global solar roadway market is the increasing global commitment toward transitioning to renewable energy and achieving carbon neutrality. Nations across the globe are formulating and implementing policies aimed at reducing greenhouse gas emissions and meeting climate change targets under international agreements such as the Paris Climate Accord. Solar roadway systems support these goals by generating clean energy directly from infrastructure that already occupies large surface areas, such as highways, streets, parking lots, and pedestrian pathways. Unlike conventional power generation systems that require separate land, solar roads make efficient use of existing space, reducing land use conflicts and maximizing utility.

Additionally, governments and environmental organizations are pushing for decentralized, resilient energy systems that reduce dependence on fossil fuels and traditional grid systems. Solar roadways offer a distributed generation model that can help meet energy demands at the point of use, especially for urban infrastructure like smart lighting, signage, and electric vehicle (EV) charging stations. Financial incentives, including tax credits, grants, and subsidies for green infrastructure development, are further accelerating investment in solar roadway technologies. With the declining cost of photovoltaic materials and growing global awareness about climate change, the demand for integrated clean energy infrastructure like solar roadways is expected to rise significantly. Renewable energy capacity is expected to grow by over 50% in the next decade. By 2030, renewables are projected to account for nearly 40% of global electricity generation. More than 130 countries have set carbon neutrality or net-zero emissions targets by mid-century. Investments in renewable energy reached over 400 billion USD annually, growing at a rate of around 10% year-over-year. Global carbon emissions are targeted to decrease by up to 30% through renewable adoption and energy efficiency measures by 2030.

Key Market Challenges

High Initial Costs and Poor Cost-Benefit Ratio

One of the most significant challenges facing the global solar roadway market is the high initial capital investment required for installation and deployment. Solar roadway panels are composed of specialized materials such as tempered glass, embedded photovoltaic (PV) cells, LED lighting systems, and microprocessors for smart functionality. These components are considerably more expensive than traditional road materials like asphalt or concrete. Additionally, the installation process is more complex, requiring skilled labor, advanced engineering, and often custom-designed infrastructure.

The cost per kilowatt-hour (kWh) generated by solar roadways is also substantially higher compared to traditional solar farms, which are installed at optimal angles and in favorable geographic conditions. In contrast, roadways must remain flat and endure harsh mechanical wear from vehicles, weather, and debris, which reduces their efficiency and longevity. This results in a low return on investment (ROI), especially when compared to more conventional renewable energy projects.

Moreover, governments and private investors are often hesitant to fund large-scale solar roadway projects without proven long-term economic viability. Several pilot projects across Europe and North America-such as the Wattway in France and Solar Roadways in the U.S.-have received criticism due to low energy output, durability issues, and poor cost-performance metrics. Without significant reductions in component and installation costs or major efficiency breakthroughs, large-scale adoption of solar roadways will remain limited, especially in developing countries where budgets for experimental infrastructure are tight. Therefore, the high upfront expenditure and uncertain economic returns pose a major roadblock to widespread implementation.

Key Market Trends

Integration with Smart City Infrastructure

A leading trend in the global solar roadway market is the increasing integration of solar roads into smart city infrastructure. As urbanization accelerates and cities face rising demand for sustainable development, governments and municipal bodies are investing heavily in smart infrastructure. Solar roadways are becoming a crucial part of this transition by offering multiple functions beyond clean energy generation, such as real-time traffic monitoring, LED-based lighting, embedded sensors, and Internet of Things (IoT) connectivity.

Many new solar roadway projects are being designed not just as energy sources but as intelligent infrastructure platforms. For instance, solar panels embedded with sensors can collect data on traffic density, road temperature, and wear conditions, which can then be used for predictive maintenance and urban planning. These roads can also power streetlights and traffic signals independently, reducing load on the central power grid and enhancing energy resilience during outages.

This trend aligns with the broader push for decentralized energy systems and autonomous infrastructure that supports digital transformation. Cities in Europe, China, and the Middle East are especially active in piloting solar roadway systems that integrate with EV charging networks, wireless communications, and adaptive lighting solutions.

Additionally, global smart city programs backed by the United Nations, World Bank, and other international bodies are promoting the use of renewable, data-driven solutions for infrastructure. Solar roadways are benefiting from this momentum and are increasingly being included in feasibility studies and pilot deployments for urban development projects.

As the cost of IoT hardware declines and cloud-based urban management systems mature, the synergy between smart cities and solar roadways is expected to deepen. This will likely open up new funding avenues and partnerships between tech firms, governments, and renewable energy companies-making solar roadways a viable component of future-ready urban landscapes.
