About Us

How We Got Here
Full Spectrum began in August 2002 as "Light Energy Systems," when lead Engineer Burke O'Neal returned from his position with the California-based Light Energy Systems to set up a similar business with his brother, Master Plumber Mark O'Neal.

With Light Energy Systems in California, Burke designed and supervised the installation of more than 100 grid-connected photovoltaic and solar thermal systems. Here in Madison, our team has installed over 400 solar energy systems. Our most visible projects include Yahara River View Apartments, Troy Gardens Co-housing, and Holy Wisdom Monastery in Dane County; the Milwaukee Recycling Center in Milwaukee; Organic Valley Cooperative in La Farge; Evansville Community Pool in Evansville; and Dominican Eco-Justice Center in Racine.

With multiple licensed plumbers, electricians, and engineers on staff, we are among the most highly credentialed solar contractors operating in the Midwest. We are licensed as an electrical and HVAC contractor in Wisconsin and are fully bonded and insured.

Our Commitment to Quality
Quality is our first priority from the moment we begin designing your system, in ordering proven components, when assembling and testing equipment and beyond final inspection. Our workmanship warranty is among the best in the industry and our major components come with longer manufacturer warranties to safeguard your investment.

Our diesel utility vans are mainly Dodge Sprinters,
achieving over 20 mpg fuel economy in service -
40%to 50% betterthan a standard conversion van.

In 2012 we leased a Chevy Volt plug-in Hybrid. It charges
with solar power produced at our shop and runs over 40 miles
on electricity before switching to gasoline.

For short trips around town, we ride a solar-charged
hybrid electric bicycle. The battery range is about
20 miles, or it can be pedaled with electric assist.
