The SunSpec Connect Webinar Series Continues November 18 at 1pm PST

In the next session, SecureG CEO Damon Kachur will discuss how crypto agility—an organization’s ability to understand, manage, and update its cryptographic systems—has become the cornerstone of cybersecurity readiness. They will explain how agile PKI architectures not only strengthen protection against today’s evolving threats but also ensure a seamless path toward quantum-resistant cryptography.

Attendees will gain a high-level understanding of:

• The role of PKI in securing distributed energy resources and connected devices

• What crypto agility means in practice for long-lifecycle systems

• How organizations can begin preparing now for the coming transition to post-quantum security

This forward-looking session will highlight the practical steps companies can take today to future-proof their cybersecurity posture while supporting the broader DER ecosystem’s move toward resilient, interoperable, and standards-based security.

The second session of the SunSpec Connect Webinar Series brought together Dr. Eric J. Vettel, President of the American Energy Society, and SunSpec Alliance Chair Tom Tansy for a thought-provoking discussion on the historical forces shaping today’s clean energy movement. Drawing from Dr. Vettel’s upcoming book The Pivot: History’s Unfinished Energy Revolution, the session explored how moments of crisis and innovation, from post-9/11 energy independence to the solar boom, led to the founding of the SunSpec Alliance and the rise of interoperability standards that define the modern DER ecosystem.

Highlights from the conversation:

• Energy “pivots” through history: Each major energy transition has emerged from crisis-driven innovation, blending policy, technology, and public sentiment.

• The birth of standards: The SunSpec Alliance formed to unify a fragmented solar industry and enable large-scale growth through interoperability.

• The next pivot — Electrification: Smart inverters, grid support functions, and electrified transport mark an irreversible shift in the energy system.

• Security and resilience: Speakers reframed distributed energy as both a homeland security and community empowerment issue.

• Grassroots innovation: Localization efforts in the City of Tucson exemplify how communities are taking control of their energy futures.

The conversation underscored a central theme: the energy transition is not just technological, it’s historical, cultural, and deeply human, driven by people and communities shaping the next great energy pivot.

Following the V2G Forum in Detroit, the SunSpec Connect Webinar Series continued with a deep dive into the future of IEEE 2030.5, featuring James Mater and Steve Kang of QualityLogic and Dylan Tansy of SunSpec Alliance. Together, they unpacked lessons learned from deployment, testing, and policy alignment that are shaping the next generation of distributed energy resource (DER) and vehicle-to-grid (V2G) interoperability.

Highlights from the conversation:

• Evolution through experience: James Mater noted that IEEE 2030.5 has moved from concept to operational maturity, its layered security and flexibility made it California’s default interconnection standard, but they also demand continuous coordination among implementers and test labs.

• Dynamic testing environments: Steve Kang explained how modern testing now focuses on multi-vendor interoperability and real-world validation, allowing implementers to test firmware updates quickly and confidently.

• Cybersecurity focus: The discussion highlighted new industry emphasis on ensuring IEEE 2030.5 systems can withstand unauthorized access and malformed messages without compromising communication integrity.

• Scaling trust and consistency: Dylan Tansy underscored SunSpec’s role in uniting technical, regulatory, and market stakeholders, using feedback from California’s programs to guide broader national deployment.

• V2G integration and beyond: Panelists shared how collaboration across automakers, utilities, and aggregators is advancing 2030.5-based V2G applications and flexible grid-support functions.

Key takeaway: IEEE 2030.5 isn’t being replaced, it’s being refined. Through iterative testing, stronger coordination, and real-world validation, it continues to serve as the foundation for secure, scalable, and interoperable distributed energy systems.

October News Highlights

Global Renewables Surpass Coal for the First Time
Renewables officially overtook coal in global electricity generation this year, marking a historic turning point in the energy transition. Solar and wind were the primary drivers, propelled by declining costs and record-level deployments across Asia, Europe, and the United States.

Why This Matters
As renewables become the backbone of the grid, distributed systems and grid-edge technologies will need to communicate seamlessly. Interoperability standards—like those developed by SunSpec—ensure that this new, decentralized generation integrates reliably and securely.

Energy Storage Set to Surge in the U.S. Grid
Forecasts show that nearly 70 GW of new utility-scale batteries are expected to come online in the next five years. The U.S. is rapidly expanding both grid-scale and distributed storage capacity as demand for grid flexibility intensifies.

Why This Matters
With more batteries entering the mix, the ability for solar + storage systems to speak a common language is vital. Standardized communication and control frameworks like IEEE 2030.5 and SunSpec Modbus make these multi-vendor ecosystems possible.

Residential Solar Market Shifts Toward Storage and TPO Models
The residential solar market showed modest contraction early in the year but is rebounding strongly heading into Q4. Battery attachment rates now approach 40 percent nationwide and more than 90 percent in some third-party ownership (TPO) markets.

Why This Matters
The growing mix of storage, financing, and ownership models adds complexity that only interoperability can solve. SunSpec standards give system operators, financiers, and homeowners a foundation of trust and compatibility across diverse technologies.

Global Manufacturing Investment Targets U.S. Solar Market
Major solar manufacturers announced over a billion dollars in new investments this month, with multiple Asian producers expanding wafer, cell, and module capacity aimed at U.S. exports.

Why This Matters
A diversifying supply chain brings opportunity but also new challenges for consistency and verification. Standards for communication, performance, and cybersecurity help ensure that imported components fit seamlessly into U.S. DER systems.

New High-Performance Solar + Storage Systems Launch Globally
Manufacturers unveiled new integrated solar modules paired with advanced liquid-cooled battery systems, reflecting a broader industry move toward full-stack DER solutions.

Why This Matters
As solar and storage merge into single offerings, interoperability between hardware, software, and grid interfaces becomes critical. Standards developed through SunSpec’s community prevent fragmentation and enable plug-and-play performance across devices.

Installers Face Financing and Policy Pressure
Residential solar installers are navigating higher loan rates, stricter underwriting, and evolving state policies around net metering and export compensation. Many are adapting by bundling storage to increase value and grid services.

Why This Matters
Financing and policy volatility heighten the need for reliable, standards-based systems that lower deployment risk. By adopting SunSpec-compliant technologies, developers can demonstrate compliance, simplify interconnection, and preserve investor confidence.

Overall Takeaway
October’s developments reinforce three key trends shaping the clean energy landscape:

• Grid Integration: Renewables are now central to electricity supply, demanding smarter, interoperable control systems.

• Storage Maturity: Energy storage is evolving from optional to essential, making standardized communication indispensable.

• Global Scale and Policy Shift: As manufacturing, policy, and finance evolve, SunSpec standards remain the common thread linking innovation to reliability and trust.
