Valued at USD 183.6 billion in 2024, the solar panels market is projected to reach USD 210.8 billion in 2025 and USD 732.7 billion by 2034, expanding at a CAGR of 14.80% during the forecast period 2025–2034. Demand is propelled by the growing need for renewable energy sources and rising investments from governments and private companies in clean energy. Leading participants include Canadian Solar Inc., First Solar Inc., Green Brilliance Renewable Energy LLP, Kaneka Corporation, Konica Minolta Sensing Europe B.V., NanoPV Solar Inc., Sharp Corporation, Solar Frontier K.K., Solaris Technology Industry Inc., Solaronix SA, SoloPower Systems Inc., Sony Corporation, SunPower Corporation, Tata Power Solar Systems Ltd., and Trina Solar Co. Ltd.

Rooftop Solar Panels Register the Fastest Growth

The rooftop installation segment is projected to grow at the fastest CAGR as rooftop solar panels offer cost savings and make it easy to calculate the price of electricity generated. Government incentives reinforce adoption. In June 2024, the US federal solar investment tax credit allowed eligible individuals to claim 30% of total solar PV system costs. In February 2024, the Delhi Solar Policy 2024 used satellite imagery to estimate rooftop generation potential and offered generation-based incentives, capital subsidies, and the opportunity to sell excess electricity. Residential buildings adopting rooftop solar PV systems with energy storage are expected to lift demand as population and urbanization increase energy needs.

Concentrated Solar Power and Floating Solar Panels Broaden Deployment Options

The concentrated solar power segment is anticipated to grow because it can store heat energy for use when sunlight is absent, addressing the intermittent nature of solar generation. It directly converts solar radiation into electricity, but cost concerns have prevented it from reaching its full potential.

The report's installation segmentation also includes floating solar panels alongside ground-mounted and rooftop systems, giving developers multiple routes to deploy capacity. By application, the commercial segment dominated in 2024 owing to cost savings, environmental preservation, and sustainability benefits, while residential demand is expected to grow significantly.

Smart Solar Systems and AI Create New Opportunities

Increasing adoption of smart solar systems integrated with technologies such as AI and IoT is expected to provide lucrative opportunities. Artificial intelligence optimizes panel orientation, tilt, and tracking systems to increase energy production. AI tools schedule maintenance and predict equipment failures, which reduces downtime, and they analyze site-specific data and satellite imagery to improve panel placement. AI-enabled simulations help industry players understand system performance and make effective design decisions, while better grid connectivity and storage management help close the gap between energy demand and supply.

Investment Momentum in Solar PV Modules and Manufacturing

Global annual investment in power generation by solar PV rose from USD 250 billion in 2021 to USD 360 billion in 2022 and USD 470 billion in 2023, with USD 500 billion estimated for 2024. Asia Pacific led the market in 2024 amid expanding use of Solar Panels across utility-scale, residential, and commercial applications.

Major commitments include Qcells (Hanwha), which invested USD 2.5 billion in a complete solar supply chain across the US, and Origis Energy, which in January 2025 announced a strategic investment from Brookfield Asset Management Ltd. that could exceed USD 1 billion in aggregate. In January 2024, Microsoft signed an eight-year agreement with Qcells to supply solar panels supporting 12 gigawatts of additional US grid capacity.

Outlook for Industry Stakeholders

Europe is anticipated to register the highest CAGR during the forecast period, supported by consumer demand for clean energy and an emphasis on reducing greenhouse gas emissions. High manufacturing and installation costs remain the main restraint, and improved efficiency is expected to enhance cost-effectiveness. Companies are spending heavily on R&D, expanding product lines, and pursuing collaborations, acquisitions, and new product launches, while newer entrants must offer cost-effective items to survive in an increasingly competitive market.
