This article discusses a pioneering pilot from kWh Analytics, in collaboration with Solar Energy Insurance Services, that aims to reward utility-scale solar projects for resilience against extreme weather. By collecting and sharing detailed project-level resilience data—especially tracker stow performance—this programme seeks to improve insurers’ risk modelling and, in turn, influence insurance pricing and asset bankability as weather events become more frequent in the U.S.
What the resilience pilot is trying to achieve
The core goal is to recognize and financially incentivize solar assets that implement design and operational strategies to withstand severe weather.
The pilot collects granular resilience data from each project and feeds it into insurers’ models, enabling a transition from solely model-based assumptions to behavior- and design-informed pricing.
This data-centric approach mirrors how telematics drive pricing in other industries.
Key emphasis areas include advances in tracker technology, higher stow angles, automated stow procedures, and richer historical stow performance datasets.
Together, these factors help insurers assess how an asset is built and run before a storm hits, rather than relying only on generic risk estimates.
Operational telematics and tracker stow performance
The programme centers on operational telematics from solar trackers and other resilience measures.
Innovations such as stow capabilities above 70 degrees, automated stow procedures, and growing historical stow data enable risk models to reflect real-world asset behavior during extreme weather.
By documenting how often and how effectively trackers reorient or stow in response to hail or high winds, insurers gain a more precise picture of potential losses and asset longevity.
Risk modelling, design choices, and insurance pricing
Enhanced tracker configurations and mitigations—like thicker heat-tempered module glass—are shown to reduce portfolio-level average annual losses and premiums compared with conventional assumptions.
A notable finding from the Solar Risk Assessment 2024 case study is that proactive stowing at 75 degrees would have cut the probability of damage by 87% versus stowing at 60 degrees during a 2022 event.
This kind of result demonstrates how engineering decisions translate into measurable financial protection for lenders and insurers.
Data integration and industry collaboration
The initiative relies on combining real-time and historical resilience data, including hail stow information, into a shared risk framework.
Real-time data from Nextpower will be integrated into kWh Analytics’ risk platform to quantify how design and operations influence expected losses with greater precision.
This approach is likened to motor insurance telematics, where premiums reflect demonstrated behavior rather than solely vetted models.
As data quality improves, more technologies and practices are expected to qualify for premium differentiation.
The programme is designed to expand through collaboration with industry stakeholders and to encourage broader insurer adoption by demonstrating tangible risk reduction in the field.
Real-time hail and resilience data from Nextpower
By incorporating Nextpower’s hail-stow datasets, the platform can more accurately model the impact of extreme weather on tracker performance and module integrity.
This richer data feed helps translate engineering choices into financial outcomes, supporting more resilient asset portfolios.
Premium differentiation and broader market adoption
With improved verification and modelling capabilities, insurers may offer tiered pricing that rewards assets with demonstrable resilience.
The expectation is that this will not only lower perceived risk but also incentivize developers to invest in resilience-enhancing technologies and practices.
A look ahead: industry impact and asset bankability
The overarching aim is to strengthen the long-term bankability and longevity of solar assets as extreme weather becomes more common across the United States.
By aligning insurance pricing with engineering and operational choices that reduce loss potential, the pilot seeks to create a more stable financing environment for solar portfolios.
Industry-wide collaboration to broaden adoption
kWh Analytics envisions expanding the framework through ongoing collaboration with project developers, insurers, technology providers, and regulators.
Shared resilience data could become a standard input for risk pricing, driving a more consistent and fair market for solar asset financing.
Enhancing bankability in a changing climate
As weather extremes intensify, the ability to quantify resilience and tie premiums to actual operational behavior offers a promising path to lower financing costs and better risk transfer terms.
This aligns the incentives of project developers, insurers, and lenders toward building a more robust, weather-resilient solar sector.
- Better risk discrimination between resilient and vulnerable assets
- Lower insurance premiums through demonstrated resilience
- Higher project bankability for utility-scale solar
- Clearer guidance for design choices that reduce losses
