Large-scale solar contractor Sunstall has launched a new recovery division to serve solar asset owners whose systems are failing to meet production expectations. Sunformance specializes in a full range of post-construction solar services — diagnostics, repair, repowering, redesign, retrofit and insurance remediation — deployed by Sunstall’s own expert field crews.
Sunformance offers solar asset owners a single, accountable partner for the full spectrum of performance recovery work: system-wide diagnostics to identify the root cause of underperformance; repair and remediation of equipment and installation defects; repowering to replace aging or failed components with modern technology; redesign and retrofit to get the most production from existing infrastructure; and insurance remediation support for assets impacted by natural disasters, severe weather or other covered events. Sunformance serves commercial and industrial solar owners, utility-scale asset operators, asset managers, developers with underperforming portfolios, O&M providers and insurance carriers that require a credible technical partner in the field.
Sunformance operates as a division of Sunstall, an installation company with more than 16 years of field experience across commercial and utility-scale projects. Sunformance crews are trained specifically in performance recovery work — diagnosis, repair and repower — rather than new construction, which means they recognize the patterns of underperformance and move quickly from assessment to resolution.
“The overwhelming majority of solar assets we encounter are not performing the way their owners expect — and in most cases, the root cause isn’t equipment failure. It’s a design decision, an installation shortcut or a problem that was present from Day 1 and simply never diagnosed,” said Helge Biernath, CEO of Sunformance. “Sunformance exists because fixing solar is a specialized skill set. We built this division specifically to do it right.”
