kWh Analytics’ new data sharing program lowers insurance costs for hail-ready solar projects
kWh Analytics has launched a data-sharing pilot program to reward renewable energy assets for extreme weather mitigation efforts. The company is expanding its risk modeling capabilities by leveraging data from solar projects that employ advanced resilience measures beyond the information typically captured in standard insurance submissions.
The initial focus of the pilot is on improving how project-level resilience data is captured and relayed to insurance carriers. Advances in tracker technology, including 70+ degree stowing capabilities, automated stow procedures and the growing availability of historical stow performance data, create new opportunities to give insurers clearer visibility into how assets are designed and operated ahead of severe weather events.
Nextpower is the first tracker manufacturer to enable the kWh Analytics data-sharing program through its NX Horizon tracking system.
“Extreme weather continues to be a significant driver of loss for utility-scale solar, and the industry is rapidly advancing how those risks are managed,” says Jason Kaminsky, CEO of kWh Analytics, a leader in underwriting the energy transition through its licensed insurance subsidiary, Solar Energy Insurance Services. “By incorporating real-world data, including stow performance from Nextpower tracking systems, we can tie insurance structures more closely to demonstrated resiliency, encouraging investments that protect assets and strengthen the long-term bankability of solar projects.”
Sharing real-time data
Modeling these resilient configurations yield substantial reductions in portfolio-level average annual losses and insurance premiums compared to baseline assumptions and stow protocols. Projects that incorporate additional risk mitigation measures, including thicker, heat-tempered module glass, reduce loss profiles further.
For solar developer owners enrolled in the collaborative telematics program, Nextpower will share real-time and historical hail stow performance data, enabling a more dynamic and evidence-based view of project risk. By integrating this operational data into its proprietary risk modeling platform, kWh Analytics can better evaluate how system design and operational readiness affect expected losses. This approach mirrors the use of telematics in the auto insurance industry, where driving behavior data is shared with carriers to better align premiums with actual risk.
“By allowing customers to share verified stow performance data from our NX Horizon trackers with Hail Pro technology, we’re enabling a shift from modeled assumptions to real-world evidence,” says Jyoti Jain, head of software product management at Nextpower. “This level of insight allows insurers to reward projects that are truly engineered and operated for long-term resilience.”
In the kWh Analytics Solar Risk Assessment 2024, Longroad Energy and Nextpower published a case study showing that proactive stowing at 75 degrees would have reduced the damage probability of an actual 2022 event by 87%, compared to stowing at 60 degrees.
The new framework recognizes the growing role of advanced solar tracker systems and site design strategies in strengthening projects against severe weather risks, including high winds, hail and flooding. As extreme weather events become more frequent across the United States, this approach is designed to better align insurance pricing with the engineering, technology, and operational choices that materially reduce loss potential and enhance long-term asset durability.
kWh Analytics expects additional technologies and operational practices to qualify for premium differentiation over time as data quality, verification, and modeling continue to advance. The company plans to expand this framework through continued collaboration with industry leaders. As kWh Analytics facilitates the communication of real-time resilience information to the insurance industry, it often sees other insurance companies follow suit.
