Customers
Enphase sells primarily through solar distributors that resell to installers, making installers and distributors the key channel customers even though the end user is usually the homeowner. It also sells directly to select large installers, OEMs, strategic partners, and some homeowners through third-party marketplaces and its online store. Demand is tied to residential solar adoption, storage attachment rates, utility economics, and the financial health of channel partners.

Strategy
Enphase is focused on expanding its digital platform, deepening engagement with installers and homeowners, and increasing online and direct-channel activity. It is also pushing market share gains in core U.S. markets while broadening international penetration in Europe, Asia Pacific, Latin America, and emerging markets. Product strategy centers on integrated solar-plus-storage, interoperability, and new adjacent offerings such as EV charging and service plans.
Improves channel stickiness, lowers service friction, and supports direct engagement.
Diversifies revenue beyond the U.S. and opens growth in underpenetrated regions.
A fuller product stack can raise attachment rates and improve system economics.
Microinverter differentiation is central to product performance and installer preference.
Geography
Q1/2026The company is headquartered in the United States and derives the majority of revenue from the U.S. market, which represented 81% of net revenue in 2025. It also sells across Canada, Mexico, Puerto Rico, Europe, Australia, New Zealand, India, Thailand, Central America, the Caribbean, and selected Asian markets, with management explicitly targeting further expansion in Europe, Asia Pacific, Latin America, and emerging markets. Manufacturing is supported by contract manufacturing, including U.S.-based facilities for some products, which matters for domestic-content eligibility and tariff exposure.

Risks
Enphase is exposed to cyclical residential solar demand, policy incentives, and the financial health of distributors and installers that sit between the company and end customers. Its manufacturing model depends on contract manufacturers and supply chains, while competition from string inverter and storage vendors can pressure pricing, features, and channel share. International expansion also adds tariff, foreign exchange, and execution risk.
