kWh Analytics, a leader in underwriting the energy transition through its licensed insurance subsidiary, Solar Energy Insurance Services, announced a data-sharing pilot program to reward renewable energy assets for extreme weather mitigation efforts. kWh Analytics 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.

Modeling these resilient configurations yields 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, tracking systems leader 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.

“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,” said Jason Kaminsky, CEO of kWh Analytics. “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.”

“We’re excited to partner with kWh Analytics on this ground-breaking program that will bring greater transparency and precision to how solar asset risk is evaluated,” said Jyoti Jain, head of software product management at Nextpower. “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. 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 U.S., 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.

PowerBank Corporation (NASDAQ: SUUN) (Cboe CA: SUNN) (FSE: 103) ("PowerBank" or the "Company), a leader in distributed solar energy, battery storage, and clean energy infrastructure across North America, is pleased to announce that its 7.1 MW Jordan Rd 2 community solar project (the "Project") located on  privately-owned brownfield lands in Skaneateles Falls, New York has  been approved for up to $1,119,618 USD in incentives through the New York State Energy Research and Development Authority (NYSERDA) NY-Sun Program. The Project is also expected to qualify for up to an additional $1,576,590 in NY-Sun incentives through the Inclusive Community Solar Adder. The Project received its municipal approvals, previously announced here. 

PowerBank is also pleased to announce that the Project has received its brownfield-specific environmental approvals to operate from the NYS Department of Environmental Conservation.

The NY-Sun Program is a public-private partnership that aims to drive growth in the solar industry and make solar technology more affordable for all New Yorkers. Led by NYSERDA, the program provides incentives and financing to expand solar adoption for homes, businesses, and communities, while supporting local job creation and advancing the state's clean energy goals.

The Jordan Rd 2 Project is expected to deliver enough energy to power approximately 895 homes annually. Once constructed and operational, following receipt of financing and final permits, the Project will be operated as a community solar project. Community solar is a solar photovoltaic system interconnected directly to the local electricity grid via distribution lines. Once the system is placed into service by the utility and generating electricity, clean energy from the site feeds into the local power grid. Depending on the size and number of panels the project has, dozens or even hundreds of renters, homeowners and electricity customers can save money from the electricity that is generated by the project. By subscribing to a project, a homeowner earns credits on their electric bill every month from their portion of the solar that's generated by the project, accessing the benefits of solar without installing panels on their home. This allows homeowners to realize a reduced cost per kW/hour from the power they consume versus standard utility rates.

PowerBank's proven expertise, with over 100 MW of completed projects and a development pipeline exceeding 1 GW, underpins the project's execution. SUUNStrategic partnerships and institutional-grade development capabilities position PowerBank to deliver reliable, high-impact renewable energy solutions.

The Project advances New York's path to 10 GW of solar by 2030. The State leads the United States in community solar capacity, having achieved the New York State Climate Act 6 GW solar goal in the fall of 2024.

There are several risks associated with the development of the Project. The development of any project is subject to receipt of a community solar contract, receipt of required permits, the availability of third-party financing arrangements for the Company and the risks associated with the construction of a solar power project. In addition, governments may revise, reduce or eliminate incentives and policy support schemes for solar power, which could result in future Project no longer being economic. Please refer to "Forward-Looking Statements" for additional discussion of the assumptions and risk factors associated with the Project and statements made in this press release.

The Clean Technology Training Trust (CTTT), a national nonprofit developing national DOL-registered apprenticeship programs in medium- and heavy-duty ZEV mechanics, announced a strategic partnership with the University of Michigan Electric Vehicle Center (U-M EV Center) to co-design industry- and labor-aligned curriculum and pre-hire/apprenticeship training pathways in medium- and heavy-duty zero emission vehicle (ZEV) systems, battery technology, and ZEV fleet maintenance and repair. This partnership represents a natural evolution of a relationship long rooted in IBEW’s collaborative history with the University of Michigan and marks a forward-facing commitment to ensuring that the doors to apprenticeship careers are open to as many individuals as possible. Launching in April 2026, the collaboration positions both organizations as national leaders in building the skilled ZEV technician workforce demanded by the accelerating transition to clean fleets in public transit, freight, and commercial transportation. 

The partnership builds on a foundation decades in the making. Through the IBEW’s long-standing engagement with the University of Michigan - anchored by programs such as the IBEW’s Electric Vehicle Infrastructure Training Program (EVITP) and deep collaborative ties around skills training - this new chapter expands that relationship into the emerging medium- and heavy-duty ZEV maintenance sector. As an IBEW affiliate, CTTT is developing its ZEV Mechanic registered apprenticeship through and for the IBEW workforce, with the capacity to deploy training across nearly 300 IBEW training centers throughout the United States. The joint initiative with U-M will develop modular curriculum that supports entry into and progression through CTTT’s labor-sponsored ZEV Mechanic apprenticeship pathway as it is built — ensuring that anyone who wants a career in maintaining and servicing the clean vehicles powering our transit and freight systems has a clear, structured route to get there. 

“This partnership reflects where CTTT is headed — and honors the road already traveled. The IBEW has worked alongside the University of Michigan for years to prepare workers for the demands of an evolving energy landscape. Now, as medium- and heavy-duty ZEV fleets accelerate across transit agencies and commercial carriers nationwide, we are taking that relationship into its next chapter. The technicians who will service and maintain those fleets must be trained to the highest standards, and the pathway to those careers must be open to everyone willing to do the work. By building this apprenticeship development work together with the University of Michigan, we are creating a scalable, labor-

driven model that starts with where the work is — on the ground, under the hood, 

Dr. Kimberly A. Moore, CCMP, National Executive Director, Clean Technology Training Trust 

The 2026 scope of work will include the co-development of modular ZEV and battery systems curriculum aligned to CTTT’s emerging ZEV Mechanic apprenticeship entry requirements and labor standards, integration of AR/VR-enabled instructional tools to simulate ZEV diagnostics, safety, and repair in immersive learning environments, and a governance framework designed for national replication across IBEW training centers. The curriculum will be grounded in the real maintenance and operational demands facing ZEV fleet technicians — from battery systems and drivetrain diagnostics to safety protocols for high-voltage vehicle servicing — ensuring that what is taught reflects what the work actually requires. The University of Michigan will contribute subject-matter expertise, instructional design, and needs assessment capacity, while CTTT will serve as the program designer and direct delivery lead — deploying this curriculum to skill and upgrade the IBEW workforce across its nearly 300 affiliated training centers nationwide. 

“The University of Michigan’s Electric Vehicle Center is proud to bring our research expertise and instructional design capacity to this labor pathway initiative. Together with CTTT, we are building the kind of demand-driven, accessible workforce infrastructure that the clean economy urgently needs.” 

Ashlee Breitner, Workforce Director, University of Michigan – Electric Vehicle Center 

"The transition to zero emission fleets is not a future challenge — it is happening now, and the IBEW workforce must be ready to lead it. Transit agencies and commercial carriers across the country are under mandate to convert their fleets, and they need technicians who are trained to the highest standard, backed by the rigor of a registered apprenticeship, and ready to work from day one. That is exactly what CTTT was built to deliver. Through our affiliation with the IBEW and our reach across nearly 300 training centers nationwide, we have the infrastructure to meet this demand at scale. This partnership with the University of Michigan strengthens that foundation, bringing world-class research and instructional expertise directly into the labor training pipeline. It is the kind of collaboration that ensures our members are not just keeping pace with the clean economy but driving it." 

Dave Reaves, Chairman, Clean Technology Training Trust 

“The IBEW recognized decades ago that the electrification of our infrastructure would require a new level of readiness from our members. That understanding led to the creation of the Electric Vehicle Infrastructure Training Program, or EVITP, in 2008. One of our earliest partners in that effort was the University of Michigan, which was among the first institutions to help roll out the program. 

EVITP was built from the ground up to prepare IBEW members for the installation and integration demands of a rapidly changing electrical landscape. 

keeping clean vehicles running — and expands opportunity from there.” 

The University’s expertise, together with its ongoing partnership with our 

What CTTT is undertaking now represents a natural and necessary next step in that partnership. As zero-emission vehicle fleets move from policy commitments to day-to-day operational reality, the IBEW workforce needs the same rigor, structure, and collaboration on the maintenance side of this transition. This is exactly the kind of work we helped lay the foundation for, and I am proud to see it advancing.” 

Michael Clemmons, International Vice President, International Brotherhood of Electrical Workers 

“For twenty years, our local has partnered with the University of Michigan on skills training programs that have made a real and lasting difference for our members. That relationship has always been built on trust, shared purpose, and a commitment to making sure our workforce is prepared for what comes next — not just what’s in front of us today. This new initiative with CTTT is a continuation of that same strong effort. The ZEV transition is already here for the fleets our members service and maintain, and having a structured, labor-driven pathway to build those skills — backed by the University of Michigan’s expertise — means our people will be ready to meet it with confidence.” 

Ryan Husse, Business Manager, IBEW Local 252 

The initiative comes at a critical inflection point for the U.S. workforce. A 2024 Center for Automotive Research workforce needs assessment found that 82% of battery industry employers reported shortages of qualified local applicants — and that employers expect hiring to increase by more than 20% between 2023 and 2026. Domestic battery workforce demand is projected to grow six-fold by 2030. Meanwhile, U-M’s own research found that auto plants in the ramp-up stages of EV production saw assembly jobs increase as much as ten times over ICE predecessor plants — directly countering earlier predictions of mass job loss. The demand for qualified medium- and heavy-duty ZEV mechanics is especially acute: transit agencies and commercial fleets across the country face binding ZEV fleet conversion mandates with insufficient technician pipelines to support them. CTTT’s ZEV Mechanic apprenticeship — currently in development as one of the only DOL-registered programs being purpose-built to meet that need through a union-supported, labor-management governed training model — represents the critical infrastructure needed to ensure those vehicles are maintained and operated safely and effectively for the long term. 

CTTT’s national apprenticeship development work — anchored in medium- and heavy-duty ZEV mechanics — is governed by a labor-management board and designed to meet this demand through high-road, union-supported career pathways. At the center of this work is a recognition that the men and women who service, maintain, and keep ZEV fleets operational are essential to the success of the clean transportation transition — and that their preparation must be as rigorous and forward-looking as the technology they will work on. The U-M Electric Vehicle Center, launched in 2023 with a $130 million state investment, brings deep research infrastructure including the nation’s first university-based battery pilot line, and aims to engage more than 1,200 students annually across Michigan campuses and partner institutions. 

National Training Alliance, has helped make the program what it is today. 

Anticipated outcomes of the partnership include co-created, labor-aligned ZEV and battery systems curriculum ready for pilot deployment in 2026 in alignment with CTTT’s emerging ZEV Mechanic apprenticeship standards, scalable pre-hire programs that strengthen pathways into ZEV Mechanic career tracks, expanded training capacity for medium- and heavy-duty ZEV maintenance and repair occupations, and a replication model designed for national deployment across labor training centers and transit agency partners. Ultimately, this work is about making sure that every individual who has the drive to build a career maintaining and servicing the clean vehicles transforming our transportation systems has a structured, labor-supported path to do so. 

Are You an Employer Seeking a Qualified ZEV-Ready Workforce? 

Transit agencies, fleet operators, and commercial carriers facing medium- and heavy-duty ZEV fleet conversion mandates are encouraged to connect with CTTT to explore workforce partnership opportunities. Through CTTT’s IBEW affiliation and its network of nearly 300 IBEW training centers, employers gain early access to a growing pipeline of union-trained ZEV mechanics — workers who will be equipped with the technical credentials and hands-on maintenance training to service next-generation fleets from day one.

Solar United Neighbors announced a new report, PPAs & Solar Leases: A practical guide to understanding third-party solar ownership, designed to help consumers navigate one of the fastest-growing pathways to rooftop solar adoption. The report highlights how third-party ownership models—including Power Purchase Agreements (PPAs) and solar leases—are rapidly expanding access to clean energy nationwide. According to the report, “Power Purchase Agreements (PPAs) or solar leases account for 45% of residential solar installations.”

“These models allow you to go solar without upfront installation costs while accessing solar energy and potential savings,” the report explains.

With federal policy changes shifting incentives toward commercial ownership, third-party solar has become an increasingly important tool for homeowners. Under these arrangements, “the PPA provider owns the solar system and is responsible for maintaining, repairing, and monitoring it throughout the contract term,” while also receiving available tax incentives.

The report emphasizes that these incentives are passed through to consumers: “These incentives are typically factored into the agreement and should help reduce your monthly payment.”

Solar United Neighbors notes that third-party models can open the door for households who may not otherwise be able to install solar. As the report states, PPAs and leases provide:

• “No upfront installation cost”
• “Immediate energy bill savings”
• “No maintenance responsibilities”
• “Predictable costs and long-term energy planning”

The guide also explains how PPAs work in practice: “A solar company installs solar panels on your roof at no upfront cost to you… you agree to buy the electricity the panels produce,” often “at a rate lower than what you would typically pay your utility company.”

At the same time, the report underscores the importance of consumer education. For example, some agreements include long-term contracts, with “most PPA contracts run between 15 and 25 years.”

Solar leases and PPAs are not available in every state. The below map shows what is available as of March 2026:

By breaking down complex financing structures into clear, consumer-friendly guidance, Solar United Neighbors aims to empower more households to make informed decisions about going solar.
