QE Solar, a provider of operations and maintenance and engineering services for solar, battery storage, and energy infrastructure, has acquired Vanguard Energy Partners‘ operations and maintenance division.
Vanguard Energy Partners is a renewable energy engineering, procurement, and construction company. Its operations and maintenance division supports commercial and utility-scale renewable energy customers.
QE Solar said the acquisition expands its national renewable energy service platform and strengthens its operations and maintenance capabilities across utility-scale and distributed generation assets in the U.S.
The company will integrate Vanguard’s operations and maintenance personnel, customer relationships, and operational expertise into its platform. QE Solar said the combined organization will improve lifecycle support and technical service capabilities for renewable energy asset owners.
Michael Seelman, EVP of Vanguard Energy Partners, said, “QE Solar’s reputation as a premier renewable energy O&M provider made them the ideal partner for our operations and maintenance division. We are confident that our customers will continue to receive exceptional service and technical support as part of the QE Solar platform. This transition allows Vanguard to remain focused on our core utility-scale EPC and development activities while ensuring long-term operational excellence for the assets we support.”
The acquisition adds to QE Solar’s expansion in the renewable energy services sector, as demand is growing for independent operations and maintenance providers that can support distributed generation and utility-scale energy infrastructure.
Previously, in February 2026, QE Solar acquired Doman Energy Group, an engineering firm specializing in utility-scale energy systems and electrical infrastructure. Doman Energy adds expertise in utility engineering design, analysis, and project support to QE Solar’s existing services, like operations and maintenance, quality assurance, commissioning, repowering, and performance optimization.
According to Mercom’s recently released Q1 2026 Solar Funding and M&A report, Corporate M&A activity in the solar sector was 47% higher YoY in the first quarter of 2026, with 28 corporate M&A transactions compared to 19 in Q1 2025.
In 2026, MARS Energy Group acquired California-based Solar Savings Direct, doing business as Solar and Roof Direct, and Sequoia Roofing & Construction. The company said the acquisitions support its focus on execution, safety, and long-term value creation in California’s residential energy and housing markets.
