The Team

Our experienced staff is just a consult away.

Matt oversees the business operations of the company, in addition to identifying and pursuing new business development. He grew up in Stafford, Virginia and graduated with a Bachelor of Arts in Environmental Science from the University of Virginia. Matt 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 open him up to the great potential of renewable energy in every day environments. Upon moving to Austin, Matt discovered a burgeoning solar industry and founded Self Reliant Solar a year later with the Corey Costello.

Cory 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 meeting Matt Lingvai and together forming 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 historical home in San Marcos.

Weinnig has served on the CPS Energy Solar Working Group with Solar San Antonio to define policies that foster the growth of distributed solar energy in San Antonio.  He earned Bachelor’s and Master’s degrees in Marketing from Louisiana State University, is an avid golfer and being from New Orleans,  something of a foodie.

A graduate of Texas Tech University, this Odessa born Red Raider brings 6 years of project management and scheduling experience in the solar industry to Self Reliant Solar. Patrick’s even keeled West Texas demeanor allows him to operate with confidence and ease through a wide variety of projects, and always does so with a smile on his face. With an older brother in the industry as well, Patrick and his family believe in the technology and look to promote it for years to come. When he is not wrangling projects throughout Texas, Patrick finds himself staying active in crossfit and soccer, and if the weather is right, you can find him basking in the Texas sun on a local patio.
