GroundWork Renewables Launches STACK Framework, Setting a New Standard for Solar Performance

The solar industry's performance gap has long cost developers time, money, and credibility. GroundWork Renewables launches the STACK Framework, a five-layer methodology designed to remove uncertainty from the entire solar project lifecycle, from resource assessment to performance analytics.

The STACK Framework is the foundation of full-stack solar intelligence, a new category GroundWork is defining to close the industry's long-standing "certainty gap." By aligning measurement, validation, and analysis across every stage, STACK helps developers, EPCs, and asset owners reduce risk, pass capacity tests, and protect long-term asset value.

"Solar can't run on guesswork," said Ann Will, CEO of GroundWork Renewables. "With STACK, we turn solar performance into a science. Every decision is backed by proven data, so our clients can defend results, secure financing, and operate with certainty."

The five layers of the STACK Framework:

• Site Characterization – Start with truth, not assumptions
• Testing – Validate what matters before it fails
• Assurance & Accreditation – Trust your data. Prove your process
• Certainty Analysis – State the certainty. Get on the same page
• Key Performance Insights – Act with confidence. Plan with precision

By replacing disconnected tools and reactive troubleshooting with a proactive, lifecycle-spanning standard, the STACK Framework sets a new bar for operational excellence. It builds on GroundWork's 15+ years of expertise in MET data, PV module testing, and solar performance analytics — all backed by its ISO-certified processes.

The STACK Framework will make its public debut at RE+ 2025 in Las Vegas, September 8–11. Attendees can explore the methodology firsthand and see how certainty compounds across projects and portfolios. Visit GroundWork Renewables at RE+ Booth V7951 or learn more at grndwork.com.
