Powered by Purpose
Hi, I’m Rob. Before starting Tiny Sun Solutions, I ran a camper van conversion company where I built fully off-grid homes on wheels from the ground up. It was in those years — wiring systems, solving tricky design challenges, and helping people hit the road — that I found what I really love: creating self-sufficient systems that give people the freedom to live life on their own terms.
What started as a passion for van life and sustainable living has grown into a mission: helping people live more freely, with less reliance on the grid and more connection to the things that matter.
Whether it’s a full electrical or plumbing install, a custom system design, a one-on-one consultation, or just diagnosing a tricky issue, every project we take on is guided by purpose.

“Rob designed our entire solar and water system from scratch. It powers everything, even our A/C, and works flawlessly. His attention to detail was next-level.”
– Bryan, Van Owner
“I came to Rob needing to add an inverter to my RV setup. He installed a new Inverter with an automatic transfer switch, and now I‘m able to make coffee on just my batteries!
– Heidi, RV Owner
Fantastic work and were very fair about my issues at hand. I was happy to find someone who knew about my solar system components and was able to upgrade my old AGM batteries to brand new Battle Borns. Highly recommend.
– Alex, Boat Owner
