What AltE does

AltE, legally Alternative Energy Store, LLC, is a U.S.-based e-retailer specializing in do-it-yourself (DIY) solar power and battery storage systems. Founded in 1999 and headquartered in Boxborough, Massachusetts, with a distribution warehouse in Fullerton, California, the company sells 327+ products across solar panels, deep-cycle batteries (LFP and AGM), inverters (grid-tie, off-grid, and hybrid), charge controllers, and mounting hardware. Its catalog spans authorized distribution relationships with tier-one brands including Enphase, Briggs & Stratton, Fortress Power, Tigo, IronRidge, MidNite Solar, Hyundai, and Eaton, among others.

The business operates a hybrid go-to-market combining a self-serve e-commerce storefront (altestore.com) with a quote-based sales motion for complete system packages. Customers can complete an online energy questionnaire, request a personalized system design and quote, purchase individual components or pre-configured kits, and optionally add expert technical support billed at $99 per hour. Distribution is direct-to-consumer for the U.S. and Canada, with international shipping handled via a third-party distribution partner, plus a dedicated Solar Installer Partner Program serving professional installers. Supporting the storefront is a content-led marketing apparatus — a DIY Solar Resource Library, blog, YouTube, Facebook, and Instagram channels — that drives organic top-of-funnel demand and reinforces the company's positioning as the "#1 online source for solar and battery storage systems, parts and education."

Revenue is generated primarily through one-time product sales (hardware margins typical of authorized distribution) plus modest professional-services revenue from technical support and system design. The company serves a fragmented mix of DIY homeowners, off-grid users seeking energy independence, residential battery-backup buyers, and professional installers, with no disclosed enterprise anchor customers. Ownership is private and independent (no parent, no disclosed VC/PE funding), and the company is led by Chairman and Co-Founder Sascha Deri.
