Local Expertise. National Experience.
Jan Thurman founded Sentinel Solar with a simple conviction: solar should be done right, or not at all.
With over a decade of coast-to-coast experience in residential and commercial solar, Jan built Sentinel to be the kind of company he'd want to hire — one that designs with precision, installs with care, and sticks around long after the utility meter starts spinning.
Sentinel Solar isn't a volume shop. We're a premium provider focused on long-term relationships, expert craftsmanship, and systems that perform for decades. We're local, we're accountable, and we're building something that lasts.
Our Team
Jan Thurman
CEO & Founder
Over a decade in solar across residential and commercial — from system design to crew management. Local to Cincinnati and committed to building a company rooted in trust, craftsmanship, and long-term relationships.
What We Stand For
Premium, Not Transactional
We don't do high-pressure sales. We consult, educate, and design the right system — then build it to last.
Local Accountability
We live here. We're not a national franchise — we're your neighbor, and we'll be here when you need us.
Installer-First Quality
We design systems that our crews can install safely and correctly. Happy installers build better systems — and we invest in them accordingly.
Long-Term Relationships
Our best leads come from referrals. That tells you everything about how we treat our customers.
