Our Experienced Staff is Just a Consult Away.

Matt Lingvai


In addition to identifying and pursuing new business developments, Matt oversees the business operations of the company. Matt grew up in Stafford, Virginia and graduated with a Bachelor of Arts in Environmental Science from the University of Virginia. He started Self Reliant Solar just a year out of college, after working for a startup company specializing in solar technical training education. His interest in solar energy began on a trip to Alaska in 2008. The visceral nature of the environment opened him up to the vast potential of renewable energy in everyday settings. Upon moving to Austin, Matt discovered a burgeoning solar industry and founded Self Reliant Solar a year later with Corey Costello.

Corey Costello


Corey leads the solar energy systems design and new technological advancement functions. Raised in Dripping Springs, Texas, Corey took an early interest in renewable energy as the general manager of PEI Electric, before starting his own electrical contractor business, Illume Electric. While growing his company, he started doing interconnection work for several solar companies in the Austin area. Eventually, he met Matt Lingvai and together formed Self Reliant Solar. Corey, who is a Master Electrician in the State of Texas and a North American Board of Certified Energy Practitioners (NABCEP) certified solar installer, spends his free time with his family and renovating a historic home in San Marcos.
