With the global energy transition accelerating and the rapid adoption of electric vehicles, a new type of infrastructure that combines shading, shelter, and clean power generation—the waterproof solar carport—is quietly emerging as a new blue ocean in the photovoltaic industry. Recent news, from a factory in Georgia, USA, to highway service areas in eastern China, and even at an exhibition in Tokyo, shows that this innovative model of “generating power overhead while parking underneath” is moving from concept validation to large-scale application, marking a new phase of growth.

Market Landscape: A Multi-Billion Dollar Track Gathers Speed

According to the latest data from several authoritative market research firms, the waterproof solar carport market is entering a phase of rapid growth. A report by HTF Market Intelligence indicates that the global market size was approximately USD 1.5 billion in 2025 and is projected to climb to USD 3.5 billion by 2033, with a compound annual growth rate (CAGR) as high as 8.4%. Another research firm, QYResearch, forecasts global sales will reach USD 832 million by 2032, with North America currently holding a dominant position, while the Asia-Pacific region is widely recognized as the fastest-growing, high-potential market.

Behind this growth lies the economic advantage of “dual-purpose land use.” Compared to traditional rooftop or ground-mounted photovoltaics, solar carports not only protect vehicles from rain, snow, and hail but also transform otherwise idle parking spaces into valuable energy-generating assets. This is particularly suitable for urban and commercial areas where land is scarce.

Technological Innovation: BIPV and Structural Waterproofing Become Mainstream

The core of industry competition is shifting from simple power generation efficiency to integrated solutions combining structure and waterproofing. In early 2025, Chinese PV mounting structure manufacturer Mibet launched a new MRac BIPV solar carport system. It features a unique internal cross waterproof rail structure. Rainwater is collected through symmetrical drainage channels into bottom gutters and discharged via pipes, claiming to achieve “complete waterproofing.” The system can withstand wind speeds of 45 m/s and snow loads of 1 KN/m², demonstrating high structural reliability.

At the recently concluded PV EXPO 2026 in Tokyo in mid-March, waterproofing technology was a key focus for many exhibitors. Mibet showcased a “double-column waterproof PV carport” that integrates structural waterproofing, EPDM sealing strips, and bidirectional drainage channels, balancing aesthetics with functionality and specifically targeting commercial and industrial applications. JinkoSolar also introduced “leakage-gutter modules” optimized for rooftop and carport scenarios, addressing drainage issues through refined design.

Cross-Sector Integration: From Power Generation to Smart Energy Hub

Waterproof solar carports are evolving into “energy hubs” for the electric vehicle era. One of the most striking examples comes from the United States: Kia’s assembly plant in Georgia suffered significant damage in 2023 when a hailstorm damaged 13,000 new vehicles. In response, Kia partnered with ARaymond Energies and others to build a massive solar carport system covering 320,000 square meters. Expected to be completed in early 2026, this project will not only protect vehicles from hail but also utilize bifacial PV modules to capture reflected light and boost output. With an estimated annual generation capacity of 10 MW, it can meet 10% of the plant’s energy needs.

In China, similar integrated applications are also advancing rapidly. Lida Group recently delivered a 5,200-square-meter steel structure solar carport at a highway service area in East China. Equipped with 2,150 modules, it has an average annual generation of 1.2 MWh. This meets 70% of the service area’s daily electricity needs, powers 12 EV charging stations, and feeds surplus energy back into the grid, achieving a deep integration of transportation and energy.

Drivers and Challenges: Policy Incentives and Supply Chain Dynamics

Core drivers come from three main areas: First, the surge in EV adoption, creating significant demand for integrated parking and charging facilities. Second, government incentives, such as tax credits in North America and Europe, and green electricity subsidies under China’s “dual carbon” goals, significantly shorten payback periods. Third, corporate ESG goals, as an increasing number of multinational companies view solar carport installations as a critical way to achieve carbon neutrality.

However, the industry also faces challenges. High initial investment costs and complex installation regulations remain major barriers to widespread adoption. Additionally, raw material price volatility (such as steel and aluminum) and the risk of asset depreciation due to rapid technological iteration place higher demands on manufacturers’ supply chain management capabilities.

Future Outlook: Standardization and Intelligence

Looking ahead, the market is trending toward modular standardization and smart energy management. According to Research and Markets, products featuring anti-corrosion coatings, quick-install foundations (such as screw piles), and integrated energy storage systems will command higher premiums. As more collaborations emerge, such as GAF Energy partnering with construction giants to develop integrated carport solutions, waterproof solar carports are poised to evolve from a standalone product into a key component of urban new energy infrastructure, offering replicable solutions for green mobility and zero-carbon industrial parks.
