SunPower has closed its strategic acquisition of leading residential solar sales company Sunder Energy, creating the U.S. residential solar industry’s fifth-largest company in installed megawatts.
The deal is expected to boost SunPower’s revenue significantly, returning it to pre-Investment Tax Credit (ITC) levels. Sunder’s 893-member independent sales force will drive the new revenue, supported by 20 permanent employees who have already transitioned to SunPower.
The companies plan to fully integrate Sunder into SunPower within one quarter to ensure maximum value from the acquisition while aligning all employees with SunPower’s long-term goals.
The companies performed a trial run prior to the acquisition, which involved integrating 64 Sunder deals into SunPower’s systems; the trial confirmed the sales team’s adaptability. The deal effectively doubles SunPower’s salesforce from 841 to 1,734 representatives.
According to Solar Quarter, SunPower’s new company structure is projected to deliver record operating income in the fourth quarter of 2025.
“This acquisition will immediately raise our revenue to its pre-ITC levels and then on to a new record. In addition, and equally important to us, it brings to us a great sales management team with its state-of-the-art sales business processes. In short, this deal is transformational for SunPower,” said SunPower CEO T.J. Rogers, in a statement. “The new revenue will be generated by Sunder’s 893-person 1099 (dealer) sales force members, which are managed by only 20 Sunder W-2 (permanent) employees, who have already transferred to SunPower. Our current plan shows that this new low-overhead revenue will generate an operating income profit record for us in Q4’25.”
