Solar vehicle market seen reaching $7.61 billion by 2035

The solar vehicle market is projected to grow from $1.85 billion in 2025 to $7.61 billion by 2035, driven by tighter emissions rules, EV adoption and faster VIPV technology development. Asia-Pacific leads the market now, while thin-film and tandem solar cells are expanding use cases across cars, buses and agricultural vehicles.

Why it matters: - Solar-integrated vehicles are moving from niche demos to a broader transportation market that can cut grid charging demand and reduce emissions. - The market’s projected growth to $7.61 billion by 2035 signals rising commercial interest in vehicle-integrated photovoltaics across passenger, commercial and off-road segments. - Regulatory pressure in Europe and China is helping create sustained demand for zero-emission transport technologies.

What happened: - The solar vehicle market was estimated at $1.85 billion in 2025. - The market is projected to rise to $2.13 billion in 2026 and reach $7.61 billion by 2035. - The forecast implies a 15.2% compound annual growth rate through 2035. - The report frames solar vehicles as vehicles that use photovoltaic cells on vehicle surfaces for propulsion, range extension or auxiliary power.

The details: - The market includes passenger cars, commercial buses, light commercial vehicles and agricultural machinery. - Solar vehicle systems are replacing passive roof structures with integrated solar cells that can generate 1.0–1.5 kW of onboard power. - The report says that can reduce dependence on grid charging by 15%–25% annually. - Monocrystalline silicon holds the largest technology share at about 42%, supported by conversion efficiency above 22%. - Thin-film technology is projected to grow at a 18.4% CAGR through 2035 because of its lighter weight and ability to fit curved surfaces. - Multi-junction and concentrated photovoltaic cells remain a niche segment valued at about $95 million in 2025. - Passenger cars account for more than 48% of revenue. - Commercial buses are the fastest-growing vehicle category, with a projected 17.1% CAGR. - Agricultural vehicles are the highest-growth segment, with a projected 19.8% CAGR. - Battery charging and range extension make up 55% of application share. - Auxiliary power systems are growing at a 14.8% CAGR. - Direct propulsion remains a niche application valued at $0.08 billion in 2025. - Asia-Pacific leads with a 38% share, and China contributes more than half of regional revenue. - Europe is expected to grow at a 15.8% CAGR through 2035. - North America generated about $0.44 billion in 2025, with the U.S. accounting for 82% of regional demand. - The report says the European Union’s revised CO₂ standards require a 55% reduction for new passenger vehicles by 2030. - China’s New Energy Vehicle Industrial Development Plan allocated more than $15 billion in subsidies and tax incentives for zero-emission transport technologies. - BloombergNEF estimates global investment in solar-integrated mobility exceeded $1.2 billion in 2024. - Oxford PV shipped its first commercial tandem modules in late 2024. - Panasonic and CATL are evaluating tandem-cell integration for 2028-model-year vehicles. - Thin-film systems are gaining traction in buses and commercial vehicles because weight savings of 40%–60% can translate into more payload capacity. - The report includes a free sample at More information.

Between the lines: - The market is shifting from aftermarket experimentation to factory-integrated solar systems built into mainstream EV platforms. - The move toward flexible, lightweight thin-film panels suggests automakers want solar integration on curved roofs, hoods and body panels, not just flat roof surfaces. - Tandem-cell progress could materially improve economics by boosting efficiency past 30% and raising daily energy harvest. - Commercial buses and agricultural vehicles may see faster adoption than passenger cars because larger surface areas and off-grid use cases improve the value proposition. - The report’s regional mix shows policy and manufacturing strength matter as much as consumer demand. - China’s vertical integration across EV and solar cell manufacturing gives it a structural advantage.

What’s next: - Automakers and Tier-1 suppliers are expected to keep testing VIPV integration for upcoming model years. - BYD, NIO and Xpeng have announced VIPV-equipped models for 2026–2027 launch windows. - Mercedes-Benz is developing a next-generation EQXX derivative with full-body VIPV coverage and 1.2 kW peak solar output. - Solar-assisted bus electrification, retrofit kits and vehicle-to-grid monetization are likely to become bigger commercial themes. - The report points to more growth if tandem cells, after-market kits and fleet energy trading gain scale. - The full report is available here.
