Solar Sector Funding Hits $25.1 Billion, Up 45% in 2026

Global solar companies pulled in $25.1 billion across 170 deals through the first three quarters of 2026, a 45% jump from the $17.3 billion raised over 127 deals in the same period of 2025, according to Mercom Capital Group.

Debt did the heavy lifting. Announced solar debt financing reached $20.4 billion across 80 deals, up 61% from the $12.7 billion over 60 deals recorded in 9M 2025. Public market financing climbed too: $2.7 billion across 32 deals, against $1.7 billion across 12 deals a year earlier.

"Solar corporate funding increased sharply in the first nine months of 2026, driven largely by debt financing. Public-market fundraising also improved, while both corporate M&A and solar project acquisitions increased as companies expanded their portfolios, recycled capital, and consolidated their operations," said Raj Prabhu, CEO of Mercom Capital Group.

Where did venture capital go?

VC money moved the other way. Solar venture funding fell 31% to $2.0 billion across 60 deals, down from $2.9 billion across 55 deals in the year-ago period. Downstream companies — the installers, developers and service providers closest to customers — took $1.3 billion of that across 39 deals.

The largest VC checks of 2026 so far went to:

• Inox Clean Energy: $343 million
• Nexamp: $180 million
• Clean Max Enviro Energy Solutions: $165 million
• Amarenco: $150 million
• Erco: $129 million

In short, lenders and public investors stepped in where venture capitalists stepped back.

How busy was the M&A market?

Corporate mergers and acquisitions picked up to 88 solar transactions through three quarters, from 76 in 9M 2025. Project acquisitions rose faster: 205 transactions against 166 a year earlier, with 34.4 GW of solar capacity changing hands, up from 29 GW.

Developers and independent power producers led the buying in Q3 2026, picking up 6.7 GW of projects. Investment firms took 1.2 GW. Other buyers — distributors plus engineering and construction companies — acquired 852 MW, and utilities bought 362 MW.

The period's marquee corporate deals:

• Inox Solar Americas acquired Boviet Solar for $750 million
• Drax acquired Bluefield Solar Income Fund for $737 million
• NextPower acquired Zimmermann PV-Steel Group for $378 million
• Greenbacker bought a 59.14% stake in Dasolar for $375 million
• TCL Solar made strategic acquisitions

Did the money flow freely?

Not entirely. Prabhu flagged friction beneath the headline growth: "Despite the higher activity, financing conditions remained challenging. Changes in U.S. tax policies, trade restrictions, rising equipment costs, and uncertainty over project economics complicated investment decisions. Capital remained available, but access to financing and investor appetite remained uneven across the industry."

The picture heading into the final quarter: more debt, more consolidation, less venture risk-taking. Whether the 45% funding growth holds through year-end depends on how quickly project economics clarify under shifting U.S. tax and trade rules.
