New York-based investment firm Captona has announced a preferred equity investment in Sunrun to support the residential installer’s project financing needs. While specific financial terms and portfolio capacities were not immediately disclosed, the parties said the deal would support 74 MW of solar and 110 MWh of battery storage across 9,400 residential installations in more than 20 states.
In solar project finance, preferred equity allows a company like Sunrun to access flexible capital over a defined term while offering the investor a prioritized return compared to common shareholders.
For Captona, the investment in Sunrun follows an earlier preferred equity transaction with community solar developer Nexamp. First announced in Oct. 2026, the firm said its investment would support 55 MW of solar generation and 5 MWh of battery storage capacity across 10 Nexamp projects in four states.
“Our partnership with Sunrun marks the next chapter in Captona’s evolution as a premier investment partner in the energy transition,” said Captona founder and CEO Izzet Bensusan, in a statement. “We’re proud to work alongside one of the largest companies in the sector as we continue to grow and scale our business, expand our investment portfolio and build on the relationships we’ve established with industry leaders.”
News of the investment comes shortly after Sunrun’s recent Q3 earnings report, in which the company revealed a 51.7% growth in revenue over the same quarter in 2025, largely on the strength of a separate financing transaction that sees the company selling many of the installations it initiates directly to a third party upon completion, allowing Sunrun to generate revenue from sales even as it maintains a long-term operating (and up-selling) relationship with the systems’ users.
Since its inception in 2007, Sunrun has raised capital from a number of sources, historically depending on a mix of traditional debt and tax equity to finance the installation of its residential systems. The addition of preferred equity from partners like Captona gives Sunrun another way to raise capital outside of its standard tax equity partnerships and senior debt facilities.
