  • “The altE Store provided me outstanding support and the best price. … I bought a 7.68kw solar system from them and I installed it myself. All items showed up in perfect condition. Installation was easy and the system works great.”

  • “Totally professional service, solid inventory, and great prices. I have accounts at multiple renewable sellers nationally but prefer using the altE Store given the reliability and expertise of its staff members.”
