Alternate Energy

What Alternate Energy does

Alternate Energy Hawaii (legal entity Alternate Energy, Inc., DBA AEI) is a Pearl City, Oahu-based solar and energy services contractor founded in 1993, privately held and operating under Hawaii contractor license C-26041. The company designs, sells, and installs rooftop photovoltaic (PV) systems for residential and commercial customers primarily on Oahu and, via electrical services, on Maui. Beyond core PV, it delivers a vertically integrated bundle that includes battery storage (Tesla Powerwall and Enphase), energy-efficient Mitsubishi Split Ductless AC, solar thermal water heating, roofing (as a 5-Star CertainTeed installer), in-house electrical work by licensed journeymen, and ChargePoint EV charging stations. It positions as a single-contractor alternative to multi-vendor installations and coordinates HECO utility interconnection and BYOD Plus battery program enrollment on behalf of customers. Distribution is direct-to-consumer and consultative: free site-specific estimates, named-salesperson engagement, and lead conversion via local SEO content, blog guides, customer testimonials, and phone-driven consultation. The company self-reports 59+ MW of cumulative installed PV capacity powering approximately 10,000 Hawaii homes. Revenue is generated almost entirely as one-time project revenue from equipment and installation, with no disclosed recurring service or software revenue stream; pricing is quote-based rather than tiered and not publicly disclosed. The company holds no external funding, is owner-operated, and is not pursuing IPO or acquisition activity per available material.

Others

• Enphase Energy: Microinverter and battery (IQ Battery) supplier that AEI installs; an enabling technology peer rather than a direct competitor but shapes the equipment landscape for residential solar.
• ChargePoint: EV charging hardware and software platform whose products AEI installs; an enabling ecosystem partner and adjacent peer for the EV-charging leg of AEI's bundled offering.
• Mitsubishi Electric (Trane Technologies ductless): OEM supplier of the Mitsubishi Split Ductless AC systems that AEI installs; included as an adjacent enabling peer for the energy-efficient HVAC side of AEI's bundled offering.

Broad incumbents

• Sunrun: Largest U.S. residential solar lease/PPA and battery installer; competes in Hawaii through national scale and financing offers against AEI's direct-purchase and cash/loan model.
• SunPower (now complete solar / Maxeon channel): National residential solar panel and installer network; competes with AEI on premium equipment positioning and has historically had dealer presence in Hawaii.
• Tesla Energy: Vertically integrated manufacturer and installer of solar roof, Powerwall, and Solar Roof; AEI is itself a Tesla Premier Installer but Tesla Energy is a potential competitor and channel partner.

Direct peers

• RevoluSun: Hawaii-headquartered residential and commercial solar installer offering PV, battery, and EV charging across the islands; the most directly comparable local competitor to AEI in product mix and geography.
• Hawaii Solar Industry Association Installers (e.g., Manu Hope, Bright Path Solar): Other locally based Hawaii residential and commercial solar installers offering PV and battery systems with similar Oahu/Maui service territories and customer profiles.

Regional players

• Greenpath Technologies (Hawaii): Hawaii residential and commercial solar installer; similar product mix (PV, battery, EV charging) and overlapping Hawaii service geography with AEI.
• Pacific Solar & Electric: Hawaii-based solar and electrical contractor serving residential and small commercial customers; overlapping product offering with AEI's PV and electrical scope across Hawaiian islands.
