A Partnership Forged in Execution

For several years, Shaun and Berek worked side by side leading teams responsible for taking solar and energy storage projects from the point of sale through final installation and commissioning. Together, they helped guide thousands of residential and commercial projects across multiple states, owning the full lifecycle: design coordination, engineering alignment, permitting strategy, field execution, and operational oversight.

Where many organizations segmented these responsibilities into disconnected silos, Shaun and Berek focused on integration. They built and managed centralized & field operations structures that improved communication between departments, elevated design accuracy, accelerated timelines, and ensured projects were constructed the right way the first time. Their shared approach consistently delivered stronger project outcomes, better customer experiences, and more predictable results at scale.

Through that work, a trusted professional partnership developed — one grounded in mutual respect, complementary expertise, and a shared belief that the renewable energy industry needed leaders who could bridge strategy and field reality.

Complementary Strengths, Shared Values

Shaun Maruna brings a rare blend of technical rigor and operational leadership. With a Mechanical Engineering degree earned cum laude from the University of New Mexico and advanced credentials including NABCEP PV Installation Professional, PMI-CP, Oregon LRT, and Idaho Electrical Specialty License, Shaun has led nationwide field operations and influenced hundreds of employees and customers across the country. His career has been defined by building systems that deliver consistent performance, ensuring projects meet targets for quality, schedule, and budget while scaling responsibly.

Berek Fasking complements that operational depth with a strategic, lifecycle-focused perspective shaped by more than fifteen years in renewable energy leadership roles. Board-certified by NABCEP and also licensed across multiple states, Berek has specialized in improving how projects flow between sales, engineering, permitting, and construction. His work has supported thousands of installations simultaneously while strengthening compliance, communication, and constructability. His connection to renewable energy began long before his professional career - growing up on an off-grid ranch, he experienced firsthand how dependable power systems directly impact everyday life. That early foundation continues to guide his practical, solutions-oriented approach today.

Together, Shaun and Berek share core values: servant leadership, accountability, continuous improvement, and a commitment to doing things correctly - not just quickly.

From National Scale to Purpose-Built Execution

While working within large national solar companies, both founders repeatedly encountered the same structural challenge: rapid growth often outpaced operational alignment. Sales would move fast, engineering would adapt, permitting would adjust, and field teams would do their best to execute — but without a cohesive lifecycle owner, friction accumulated. Rework increased, timelines slipped, and margins eroded.

Rather than accept this as an industry norm, Shaun and Berek envisioned a different model: a company built specifically to own and align the full project lifecycle from concept through completion.

That vision became Concentric NRG.

Why “Concentric”

The name reflects the founders philosophy. Successful clean energy projects require multiple stakeholders - contractors, developers, engineers, AHJs, utilities, and property owners - all operating in coordinated alignment. Like concentric circles, each layer must be centered on the same goal: delivering compliant, constructible, high-quality energy systems that perform for decades.

CNRG (‘synergy’) exists to keep those circles aligned.

A Track Record That Builds Trust

Between them, Shaun and Berek have helped deliver thousands of solar and energy storage installations across diverse markets and regulatory environments. They have managed centralized operations teams, coordinated engineering and design support groups, navigated complex interconnection pathways, and supported field execution at national scale. Their experience spans residential portfolios, commercial projects, and multi-state operational programs where consistency, compliance, and communication are critical.

Clients trust CNRG because its founders have lived every phase of the project lifecycle — not in theory, but in practice - and understand where projects most often encounter risk. More importantly, they know how to prevent those issues before they arise.

The CNRG Mission

Concentric NRG was built to help contractors, developers, and property owners execute renewable energy projects with confidence. By aligning strategy, design, permitting, utilities, and construction from day one, CNRG ensures projects move faster, pass inspection the first time, and protect long-term performance and profitability.

At its core, the company’s mission is straightforward: Help clean energy projects get built correctly, efficiently, and at scale - with integrity guiding every step.

Looking Forward

Shaun and Berek founded CNRG not to simply participate in the growth of the renewable energy industry, but to strengthen its operational foundation. As solar and storage adoption accelerates nationwide, the need for experienced lifecycle leadership will only increase. Through their combined expertise, trusted partnership, and shared commitment to excellence, they are building a company designed to serve as a steady, knowledgeable guide through the complexity of modern energy projects.

Concentric NRG stands as the result of years of collaboration, thousands of successful projects, and a shared belief that when people, process, and purpose are truly aligned, clean energy can be delivered the right way - every time.
