Brothers and UW-Madison mechanical engineering alumni, Burke and Mark O’Neal, started Full Spectrum Solar in August 2002. Burke had recently returned from his position as a lead engineer with one of the largest California solar energy companies.
Together, they envisioned an environmentally friendly business installing only top quality photovoltaic systems, with unmatched customer service and a competitive price.
Today, Full Spectrum Solar is one of the most highly-credentialed solar energy contractors in the Midwest.
Among our experienced staff, we have degreed mechanical and electrical engineers, with over 40 years of combined renewable energy experience between them. Our team includes master electricians, two with over 15 years of photovoltaic installation experience, journeyman-level electricians, NABCEP-Certified Installers, and solar-experienced roofers.
We are proud of our zero-energy-cost office and shop on East Washington Ave and our energy-efficient vehicles, including three electric vehicles. In early 2013, our office and shop was awarded an ENERGY STAR 100/100 rating. That’s the highest rating in Wisconsin; better than 99 percent of comparable buildings!
Our team has installed over 800 of the finest quality solar energy systems in southern WI. We’ve designed systems for homes, apartments, and a wide variety of businesses and non-profits.
Our most visible projects include Forest Edge Elementary School, Dane County Job Center, Willy Street Grocery Co-op, 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.
