Our Philosophy

“Any time the sun shines, we get energy”
Keith Knowles, Vice President, Solar Practice Lead

We believe that, whenever possible, a project should leverage the sun. Whether it’s simply passive solar or a full blown photovoltaic array, solar can benefit your project immensely.

Though the up-front cost seems significant, the lifetime benefit of a solar system can be huge.

We strive to find new and better ways to power, heat and cool your home.

One example we like to point to is the average cost of a new car in the US: $28,400 (source: National Automobile Dealers Assocciation). Guess how much that investment depreciates? Well, according to Consumer Reports, 40 to 50 percent in the first 4 years!

For about the same amount of money, a homeowner can install solar and watch their investment appreciate as energy rates increase. Learn more about how solar payback can be achieved.

Email or call us today, and we can talk about how Solar can benefit your bottom line and appreciate the value of your home or business.
