About Mainstream Green Solutions LLC
Mainstream Green Solutions LLC was founded in 2009 in Wildersville, Tennessee, by navy veteran Ernie Williams. The veteran-owned company began when Williams obtained Sharp Solar Certification and launched the business as a side venture while researching proven solar technologies. In 2012, he added NABCEP PV Installation Professional certification, and the firm transitioned to full-time operation after 13 years. The company designs, installs, and services photovoltaic and battery storage systems for residential, agricultural, and commercial clients across West Tennessee. Services include system design and engineering, energy consulting, PV system maintenance, EMP protection, and conversion of legacy TVA grid-tie installations to self-consumption with battery backup. Projects range from off-grid tiny homes and mobile hybrid campground power stations to a solar farm in Gibson County and whole-home backup systems starting under $10,000 installed. Customers include families, farmers, and businesses such as a medical clinic that received a custom installation. The firm also assists rural businesses and farms in securing USDA REAP grants, which can cover up to 50% of system costs for 2024–2025. All installations use equipment from manufacturers like Sol-Ark, for which Mainstream Green holds Gold Installer status. Williams emphasizes honest, data-driven proposals and a commitment to service: “If we install it, we will service it.” The company avoids chasing technology trends, instead relying on proven components and transparent cost analysis tailored to each client’s unique situation.
