Solar Energy Market Analysis by Mordor Intelligence

The Solar Energy Market size in terms of installed base is expected to increase from 2.35 Terawatt in 2025 to 2.92 Terawatt in 2026 and reach 7.25 Terawatt by 2031, growing at a CAGR of 19.91% over 2026-2031.

This Solar Energy market size expansion is anchored in utility-scale photovoltaic projects that now match or beat wholesale power prices across most sunny regions, while U.S. tax credits under the Inflation Reduction Act (IRA) have sparked USD 110 billion of domestic manufacturing pledges. Corporate power-purchase agreements (PPAs) from data-center operators, the growing pipeline of photovoltaic-battery hybrids, and accelerated policy support in land-constrained countries all reinforce a virtuous cycle of falling costs and expanding demand. Asia-Pacific remains the center of gravity, yet the Middle East and Africa are emerging as the fastest-growing territories as solar projects are bundled with green-hydrogen export schemes. Crystalline-silicon modules still dominate, but incremental advances such as tunnel-oxide passivated-contact (TOPCon) cells and bifacial designs continue to lift conversion efficiency. On-grid projects keep the lion’s share of deployment, although off-grid systems for rural electrification are gaining momentum as pay-as-you-go financing spreads through mobile-money platforms.

Segment Analysis

By Technology: PV Dominance Drives Innovation

Solar photovoltaic commanded 99.7% of the Solar Energy market share in 2025. Falling levelized costs, down 4.6% in 2024, place PV ahead of gas peakers and onshore wind in many regions. The segment is expected to grow at 19.92% CAGR through 2030, powered by efficiency gains such as perovskite-silicon tandem cells hitting 31.6% laboratory performance. Multi-junction designs could push conversion rates beyond 40%, opening space-constrained rooftops and vehicle-integrated niches. Concentrated Solar Power retained a marginal footprint because solar-plus-battery hybrids now achieve half its levelized cost in high-irradiance regions.

Silicon’s cost trajectory keeps eroding the addressable space for thermal tower and trough projects, though CSP still serves process-heat niches. The Solar Energy industry continues to funnel R&D toward wafer-thinning, metallization-free contacts, and back-contact architectures to inch efficiencies closer to 25% across mainstream product lines.

By Grid Type: Off-Grid Uptick in Emerging Regions

On-grid assets represented 89.3% of 2025 capacity, but off-grid systems are expected to expand at 22.2% CAGR to 2031 as governments target universal access. Kenya alone deployed 2.5 million pay-as-you-go kits by 2024, and Nigeria added more than 300 MW of solar mini-grids that bypass costly transmission extensions. Development-finance institutions extended USD 1.2 billion to mini-grid programs across 15 countries in 2024, with battery storage now standard for 24-hour supply. Rising electricity tariffs in parts of South Asia further tilt new capacity toward community-scale solar rather than diesel.

By End User: Residential Growth Hinges on Policy Certainty

Utility-scale projects held 52.9% of the 2025 market thanks to auction-driven procurement at costs below USD 0.03 per kWh. Residential installations, though battered by high rates in 2024, are still projected to achieve a 21.5% CAGR to 2031 as financing eases and self-consumption rules mature in emerging markets. Commercial and industrial rooftops showed resilience, growing 17% in 2024 because corporate buyers monetized both energy savings and renewable-certificate revenue streams.

Geography Analysis

Asia-Pacific retained 64.5% of installed capacity in 2025. China’s cumulative fleet surpassed 800 GW after adding 330 GW in 2024, with Shandong, Henan, and Jiangsu registering the highest provincial totals. India reached 90 GW, catalyzed by domestic manufacturing incentives that underwrote 40 GW of new factory commitments. Japan, South Korea, and Australia collectively added another 35 GW, with floating, agrivoltaic, and hybrid models compensating for land scarcity and grid bottlenecks.

The Middle East and Africa Solar Energy market is projected to register a 22.7% CAGR through 2031. Saudi Arabia’s 4 GW NEOM, the United Arab Emirates’ 2 GW Al Dhafra project, and Egypt’s 3.6 GW Suez Canal pipeline anchor this upswing, complemented by a surge in African off-grid kits that passed 5 million households by 2024.

North America installed 35 GW in 2024, dominated by 32 GW in the United States, where IRA incentives and state renewable portfolio standards converged. Texas led with 8.5 GW, while California followed at 6.2 GW despite rising curtailment. Canada’s 2.8 GW addition leaned on Alberta’s merchant market. Mexico’s progress stalled at 1.2 GW amid regulatory uncertainty.

Europe added 62 GW in 2024. Germany led with about 15 GW, Spain followed with nearly 9 GW but wrestled with interconnection backlogs, and Poland installed 6 GW driven by small-scale prosumers. The EU’s Net-Zero Industry Act set a target of 30 GW of localized manufacturing by 2030; however, only 8 GW of projects had broken ground by year-end 2024.

Regulatory Landscape

Solar deployment continues to be shaped by incentive-led frameworks and fast-evolving trade and permitting rules, with policy design increasingly shifting from pure build-out toward grid integration and system reliability. In the United States, the Inflation Reduction Act, particularly Section 45X manufacturing credits, has been a key anchor for domestic PV manufacturing investment decisions, while customs enforcement actions under the Uyghur Forced Labor Prevention Act affected import clearance for parts of the PV supply chain through 2024, strengthening compliance and traceability requirements for developers and EPCs.

Across Europe, permitting and siting reforms are increasingly linked to Renewable Energy Directive III, including the rollout of renewable "go-to areas" intended to streamline approvals for qualifying projects. International policy trackers such as the IEA Global Energy Policies Hub and the IEA/IRENA policies and measures database indicate a rise in clean-energy trade measures during 2025, which adds procurement risk management pressure for module sourcing. Policy emphasis is also moving toward storage-coupled solar configurations to address curtailment and negative pricing in high-penetration grids.

Competitive Landscape

The top ten module vendors supplied roughly 65% of 2024 shipments, reflecting a moderately concentrated Solar Energy market. LONGi, JinkoSolar, and Trina Solar each shipped more than 40 GW but grappled with single-digit gross margins after polysilicon oversupply dragged prices below USD 0.11 per watt. Vertically integrated producers continue to backstop earnings by moving further upstream into wafer and ingot production.

First Solar’s cadmium-telluride line held around 5% global share yet dominated the thin-film niche. IRA production credits and independence from polysilicon imports allowed the firm to scale U.S. capacity toward 9.5 GW by 2026. In the balance-of-system arena, Huawei and Sungrow controlled nearly one-third of global inverter volume, while Nextracker led trackers with shipments exceeding 10 GW and a healthy backlog into 2027.

Strategic moves during 2025-2026 included Qcells’ vertically integrated Georgia complex, JinkoSolar’s rapid TOPCon capacity upgrades, and Nextracker’s expansion of U.S. steel-supply agreements that shortened delivery cycles for trackers serving domestic projects. Emerging disruptors such as Oxford PV’s perovskite tandems and Maxeon’s high-efficiency back-contact panels are courting premium rooftop and space-constrained segments but must validate long-term field reliability before mass uptake.

Market Opportunities and Future Outlook

Hybridization and flexibility are emerging as a primary whitespace for capacity owners and developers as curtailment and interconnection constraints intensify in more mature solar regions. Utility-scale solar-plus-storage is moving from pilot deployments to multi-gigawatt commitments, illustrated by Masdar reaching financial close in July 2026 on a 5.2 GW hybrid solar project in the UAE paired with 19 GWh of battery storage. Large corporate offtakes are also increasingly specifying firmed or shaped renewable supply rather than standalone PV output, and corporate procurement remains a major demand pool for utility-scale builds, with data-center-driven PPAs already exceeding 25 GW of solar PPAs executed during 2024 in the report context.

Supply-chain and technology differentiation also offer near-term opportunity as buyers and developers seek higher-efficiency modules and diversified sourcing. Manufacturers are accelerating N-type architectures (including TOPCon and back-contact roadmaps) to maintain competitiveness as module ASPs compress, while industrial policies such as the IRA in the United States and localized manufacturing targets in the EU (Net-Zero Industry Act) influence upstream and midstream investment decisions. In off-grid and emerging-market segments, pay-as-you-go financing and mini-grid programs continue to broaden demand, supported by the report context’s kit deployment milestones and development-finance commitments.

Recent Industry Developments

  • July 2026: Masdar reached financial close on a 5.2 GW hybrid solar-plus-storage project in the United Arab Emirates that includes 19 GWh of BESS capacity. The transaction highlights how multi-hour storage is being contracted alongside PV to deliver firmer renewable supply and reduce curtailment exposure in high-build markets.
  • May 2025: Meta signed two PPAs with AES for 650 MW of solar to support data centers in Texas and Kansas. The deal underscores how hyperscale buyers are underwriting utility-scale pipelines through long-tenor offtakes, shaping project development toward locations with transmission access and scalable interconnection.
  • July 2024: LONGi and JinkoSolar announced a settlement of global patent disputes. The agreement reduces litigation overhang for two major module suppliers and can simplify procurement decisions for developers and EPCs that prioritize supply continuity across multiple jurisdictions.

Data Sources, Market Sizing, and Validation

Desk Research

Our desk work starts by building a clean base of installed capacity by country and by year, then aligning it with technology (PV vs CSP) and grid connection status. We rely on public and official sources such as IEA PVPS publications, IRENA renewable capacity statistics, the International Energy Agency, national energy ministries or power regulators, and grid operator or utility interconnection updates when available.

To keep the model grounded, we also review customs and trade dashboards for solar components in key importing markets, policy documents on renewable targets and auction schemes, and reputable press releases that confirm commissioning dates and plant expansions. For consistency checks at the company level, we use annual reports, investor presentations, and project disclosures, and when a public record is thin we selectively use paid subscriptions for company financials and patent databases. The desk research sources listed here are illustrative only, and additional public references were used for data collection, cross-checking, and clarification.

Primary Interviews and Surveys

Primary calls and surveys are used to confirm how capacity moves from announcement to commissioning, and to stress-test our assumptions on retirements, repowering, and grid connection timing. We speak with a mix of project developers, EPC and O&M participants, utilities and grid specialists, and sector experts across APAC, EMEA, and the Americas so country-level capacity signals are not overfitted to one region.

Distribution of primary research fieldwork respondents

Company typeRespondent positionRegion
Top tier: 30% CXOs: 15%APAC: 47%
Mid tier: 49% Functional/Unit leaders: 36%EMEA: 35%
Smaller Players: 21% Managers: 49%Americas: 18%

Market-Sizing & Forecasting

Sizing is built from a top-down capacity accounting flow where national renewable statistics, grid-connected additions, and project commissioning records are used to reconstruct cumulative installed capacity year by year, then rolled up to regional and global totals. To keep the output realistic, we corroborate totals with selective bottom-up checks, such as sampled utility-scale project pipelines, developer announced commissioning schedules, and a reasonableness pass on additions implied by import activity and module shipment commentary (used only as a directional check).

Key inputs that influence the annual path include newly commissioned capacity (GW), decommissioning and repowering assumptions, the split between PV and CSP additions, the timing gap between mechanical completion and grid synchronization, and policy-driven installation cycles such as auction calendars and net metering changes. When a country has limited public updates, we fill gaps using peer market ratios for build times and historical seasonality patterns, then adjust after expert feedback so the implied run rate does not change without a clear trigger.

For forecasting, we use scenario analysis supported by trend fitting on additions. In practice, the main drivers are renewable targets, grid expansion readiness, auction pipelines, and expected cost trajectories, which respondents confirm as realistic. The result is a forecast path that is easy to reproduce because each step ties back to capacity additions and timing assumptions that can be revised when new projects are commissioned.

Data Validation & Update Cycle

Before finalizing, we run cross-checks between the modeled capacity totals and independent demand-side signals, including country renewable capacity totals, published annual PV additions, and public commissioning trackers for large projects. Outliers are reviewed with simple variance rules, and when the gap is meaningful, analysts revisit country assumptions and re-contact a subset of experts to confirm whether delays, curtailment rules, or policy shifts are the main cause.

Each report goes through multi-step internal reviews where calculations, unit consistency (GW vs TW), and regional rollups are verified before sign-off. Reports are refreshed annually, and interim updates are done when there are material events, such as major policy changes, large commissioning waves, or visible slowdowns in interconnection. Right before delivery, an analyst performs a final pass so the client receives the most current view available at that time.

Mordor Intelligence's Solar Energy Market Estimate Compared With Other Published Estimates

Different published solar market numbers often do not line up because the term market can refer to the installed base, yearly additions, or revenue, and each choice changes what is counted and which year looks larger. We also see differences when studies mix PV with other solar-related categories, or when they use different timing for currency and calendar-year cutoffs.

Global installed PV capacity signals from IEA PVPS (such as 2.26 TW in 2024) are used as an external reasonableness check that keeps Mordor Intelligence's 2.35 TW (2025) estimate tied to operating capacity rather than shipment or investment value. Other gaps usually come from whether CSP is included, whether uncertified off-grid systems are counted, and whether a source reports DC capacity versus an AC equivalent, which can move totals even when the underlying projects are the same.

Benchmark comparison

SourceMarket SizeGaps in Research Methodology
Mordor Intelligence USD 2.35 T (2025)
Industry Agency A USD 2.26 T (2024)This figure is reported for PV only and for a prior year, and it is often presented in DC terms without explicitly aligning CSP inclusion or the operating plant boundary used for cumulative capacity.
Energy Journal B USD 2.20 T (2024)The estimate commonly reflects a rounded end-2024 PV capacity statement, and it may reflect a narrative threshold rather than a country rollup with explicit treatment of commissioning timing and off-grid certification.

The spread is mainly explained by year alignment and boundary choices, especially PV-only counting, DC versus AC presentation, and how strictly operating status is applied. By keeping the model anchored to commissioning-led capacity adds and then checking it against independent global capacity markers, we can offer a practical total that buyers can trace and update with new public releases.
