Market Forecast for 2026
According to the latest reports, global solar photovoltaic (PV) installations are projected to reach approximately 649 gigawatts (GW) in 2026, marking a slight decline from the record-setting figures of 2025. This represents the first annual slowdown in solar capacity additions, primarily driven by a significant reduction in China's contributions—expected to fall by about 33% compared to previous levels.
Despite the slowdown, the market is anticipated to stabilize and prepare for renewed growth, with forecasts suggesting a rebound in installations starting in 2027.
The solar PV market size was valued at around USD 323.5 billion in 2025 and is expected to grow at a compound annual growth rate (CAGR) of 8.1% from 2026 to 2035. Growth will be fueled by the integration of solar PV across various sectors, including agriculture and business operations.
Directional Analysis
The global solar industry is entering an adjustment phase where competition rules are being redefined. Leading analysts from BloombergNEF (BNEF), S&P Global, and the International Energy Agency (IEA) emphasize that while demand for solar energy remains strong, market dynamics are evolving. The focus has shifted from merely scaling production to enhancing competitiveness through innovation and technology.
Key factors driving this transition include:
- Policy Changes: New regulations and incentives, especially in major markets like the U.S. and China, are reshaping installation rates and market strategies.
- Technological Innovations: Advancements such as high-efficiency solar panels, bifacial designs, and emerging technologies like perovskite solar cells are improving energy output and reducing costs, making solar more accessible.
- Geopolitical Factors: Global political and energy strategy dynamics are influencing market stability. As energy security concerns grow, demand for renewables like solar is expected to increase, though at a more cautious pace.
Emerging Trends in the Solar PV Market
- Technological Advancements: New solar technologies such as half-cut cell panels and smart storage solutions are revolutionizing energy generation and management by boosting efficiency and lowering costs.
- Storage Integration: Combining solar with energy storage is becoming vital. Solar-plus-storage projects are gaining traction to meet growing demands for reliable, flexible energy, especially from hyperscale data centers and commercial operations.
- Sustainability Focus: Corporate social responsibility and carbon neutrality efforts are driving increased investments in solar energy, further boosting market demand.
- Regional Developments: While the global market slows, certain regions like the U.S. continue strong growth, with projections of adding between 41 GW and 52 GW annually until 2035, supported by favorable policies and incentives.
- Market Correction: The anticipated stagnation in 2026 is seen as a necessary market correction to recalibrate and foster innovation and strategic partnerships for future expansion.
Conclusion
Entering 2026, the global photovoltaic market is at a pivotal juncture. Although a temporary slowdown is expected, underlying factors such as technological innovation, policy reforms, and sustainability priorities are setting the stage for future growth. The industry’s trajectory points toward a greener, more sustainable energy future illuminated by ongoing advancements.
