COO at SunVest Solar
"Ampacity would like to express our gratitude to Knobelsdorff for being a top-tier solar partner. From engineering to procurement, construction, speed, and QUALITY, Knobelsdorff has definitely separated itself from the upper echelons of the solar design and installation field. The professionalism and business relationship are very comforting in an industry which starts and stops for reasons outside of anyone’s control. When visiting a Knobelsdorff site, you can see the care taken from the torque marks to stainless clips used for wiring management. Knobelsdorff truly designs and builds a product meant to last 30 years. Thank you so much for making our product shine."

“KE supported our Marshall, MN project with work that included complete mechanical and electrical installation scopes, and commissioning support. Their professionalism and expertise were key in meeting both schedule and budget without compromising quality or safety. KE’s continued support does not go unrecognized, and we are grateful for the committed partnership between KE and US Solar.”

APA Solar is a leading manufacturer and provider for fixed-tilt ground mount solar racking and foundation solutions and had the pleasure to partner with Knobelsdorff on the Prairie Island Solar Project by providing racking and mechanical installation services. APA has had an ongoing relationship with Knobelsdorff for many years and we enjoy working with their team. They do an excellent job of managing their projects from start to finish and are considered a valued partner to APA.

Safety drives every decision in the field and in the office. KE crews plan the work and work the plan: pre‑task planning, JSAs, LOTO, daily huddles, and stop‑work authority. The result is predictable execution, protected people, and quality work.

We uphold IRA compliance standards within the renewable energy sector, operating an in-house apprentice program that guarantees at least 15% of our workforce are registered apprentices. This commitment not only meets industry benchmarks but also nurtures skilled professionals for the future of renewable energy.
Airstreams Renewables provides fast-paced, hands-on training focused primarily on preparing military veterans for entry-level roles in the renewable energy sector. Led by instructors with military backgrounds, the program emphasizes safety, camaraderie, and skill-building. Knobelsdorff regularly visits their California facility to give on-site presentations, answer questions, and offer mentorship through ongoing communication. This partnership has resulted in numerous successful hires, with excellent retention fueled by our supportive, merit-based culture.
“KE is unique because it’s so family-friendly. This was my first civilian job after the military, and it was more welcoming and supportive than I expected. KE maintained strong communication during training, and unlike other companies, didn’t hesitate about hiring veterans. My supervisor was patient and believed in me, so much so that I was promoted to site coordinator instead of the solar installer role I originally applied for. KE gave me the opportunity to grow, and I look forward to advancing further.”

In Chicago, our relationship with Evolve has grown into a sustainable, meaningful collaboration. Focused on education, empowerment, and innovation, the foundation provides industry certifications, stipends, and life skills training to individuals from underserved communities. Participants also receive additional support services related to housing, financial guidance, and emotional support for long-term success.
“KE gave me the opportunity to turn my life around. I joined through the Evolve program and got into their free apprenticeship program, earning while learning, gaining hours, and developing skills. Before this, I was angry, had poor work habits, and lacked direction. KE held me accountable and helped shape me into the man I’m meant to be. They treat you like family and give you the motivation and trust to grow every single day.”

The most important part of a solar operation is finding an EPC that can perform the work and stand behind it. We’ll be your go-to from first study to operations, a single accountable partner across EPC and O&M. Field-tested crews deliver repeatable results, hold the schedule, and keep the site safe. Reporting is clear, budgets stay tight, and closeout is clean. When the switch flips, our service team stays with the asset for life.
