One Sun - Solar Done Right

“One Sun installed our PV system in Spring 2010 and it has been working great since the first day of activation. We also installed a carport structure that the PV system is attached to; Warren and One Sun coordinated the installation of the structure into their contract in addition to their own PV work. We had a few delays to our construction schedule and One Sun was very flexible to work with. We would recommend them to other wineries.”

“I have been a superintendent for over 20 years and … without question, this was one of the best experiences ever working with a contractor… The project was completed on time and on budget. Awesome! The entire crew was respectful and courteous and focused on their work. Of course, this work ethic stems from the top. It was a pleasure doing business with One Sun and I would highly recommend your company to any school district.”

“One Sun’s installation of our 396 kW solar system was executed smoothly from initial site assessment to on-time completion. The professionalism and courtesy of the entire team was impressive. At every stage of the process they were responsive to our facility’s daily operations. We enjoyed business as usual for the entire duration of the project.”

“One Sun’s installation of our solar system has been a good fit. Warren and I are optimistic about this partnering of engineering and nature: it works! We are committed to green growing and now we are saving the other kind of green too.”

“We carefully weighed the decision to go solar in 2008. The system is running slightly ahead of projections, and we couldn’t be more pleased with the energy savings we’re seeing. When the payback period ends, electricity charges are expected to drop by 60 percent where the solar panels are installed. Plus, we’re doing our part to help improve the environment.”
Jeremiah Smith, Executive Vice President and CFO
First Northern Banks, Dixon/Winter/Sacramento, CA

“Our wonderful 5 KW photovoltaic system, designed and installed by One Sun, Inc., has been producing all the electric power we need since February 2011. We LOVE watching the PG&E meter run BACKWARDS! Thank you so much.”
