At Arx, we’re here to bring practical, dependable energy solutions to the communities that need them most. We specialize in supporting tribal nations, food banks, and low-income projects with clear, realistic planning for solar, battery, and microgrid systems.

We believe that the right energy system can make a real difference, and we’re proud to help make that happen.

Who We Are

I'm Kyle Hertzog, founder of Arx. I started this company after years in the field—first turning wrenches as a journeyman electrician, then serving as an electrical administrator in the solar field, and on to leading full solar system designs and installations. I've worked on rooftops, in trenches, and across job sites all over Washington. This hands-on experience is what shapes everything we do here at Arx.

We are not here to push products or flood you with jargon. We offer honest advice and real technical support. Our clients trust us because we keep things clear, grounded, and focused on what actually works: for your site, your budget, and your community.

What We Do

We focus on:

• Feasibility studies for solar, battery, and microgrid systems

• Independent consulting for project design, permitting, and utility coordination

• Support for grant-funded, community-led, and tribal energy projects

We take pride in helping communities secure funding, make smart decisions, and move forward with confidence. Our reports are detailed but readable. Our feedback is direct but respectful. And our goal is always the same: to support you in building something that lasts.

Why We Do It

There’s a lot of noise in the energy world. Our mission is to cut through it, so that underserved communities can access good, reliable systems without the confusion or the sales pitch.

We’re especially proud to work alongside Tribal leaders, nonprofits, and local champions who are trying to do the right thing for their community. That’s the kind of work that matters. And we’re here for it.

If you're building something that needs to work—not just on paper, but in the real world—we’d love to be part of your team.
