Hedge Against Rising Utility Rates

Solar Energy makes pure financial sense. That’s why leading organizations in every region are deploying solar at an ever-increasing rate. A combination of innovation and economies of scale have reduced the cost of solar more than 45% since 2012*, making it cost effective today, while the price of traditional electricity remains an ever increasing and volatile cost center.

We have used many contractors at this building — we have completed numerous renovations and a major expansion — and Third Sun Solar was the most user-friendly contractor we ever used. The whole process was very easy. My staff is very pleased.”

Our commercial operations team is very familiar with Third Sun Solar and have a great deal of respect for their expertise. It seems like you’ve partnered with the right team to bring your project to completion.

The process of going solar was very smooth for us, and our first system produced exactly the power we expected. Once we went through the process, we had great confidence about doing it again, and adding more solar. It’s been a great experience.

The positive business impact from our tiny, street-side 3-kilowatt solar canopy has been far larger than the 3kW of electricity it generates.
