Robert Green - Founder and CEO


Hello, and welcome to BTU Insight!

As an engineer and an energy sector professional, I’m passionate about the possibilities of renewable energy. Renewable energy is making a positive impact in so many areas of our lives—from healthcare, to job creation, to lower energy bills.

As a veteran of the United States Navy, I’ve honed skills that allow me to lead and get things done. My goal as CEO of BTU Insight is to ensure that we continue making solar energy products that make a difference in people’s everyday lives. I want to create new solar-energy jobs and careers. I also want to share my company’s innovations with public schools so that students can imagine new possibilities from solar energy.

I invite you to join me and my team as we forge a path of new ideas and new products. Together, we can make our communities and neighborhoods better while enjoying the benefits of renewable energy.

Thank you for your time, and feel free to contact me with any questions. I’d love to hear from you!
