Why did Tesla stop selling Powerwall?
Tesla discontinued Powerwall sales due to declining consumer trust linked to Elon Musk’s political stance, intensified competition from alternatives like Franklin aPower, and strategic prioritization of commercial-scale Megapack systems. While Powerwall dominated residential storage for years, brand polarization and rival products with longer warranties eroded its market share, prompting Tesla to focus resources on high-margin utility and industrial projects.

What triggered Powerwall’s market decline?
Brand controversies and competitive pressure accelerated Powerwall’s fall. EnergySage data shows 68% of U.S. solar buyers actively avoided Tesla in 2025 Q1, while Franklin aPower captured 14% of former Powerwall installers with 15-year warranties.
Beyond brand perception, technical stagnation played a role. Powerwall 3’s 13.5kWh capacity and 90% round-trip efficiency failed to surpass Franklin’s 15kWh/92% specs released six months earlier. Pro Tip: When retrofitting existing solar arrays, verify battery chemistry compatibility—Franklin’s LFP cells tolerate wider temperature ranges than Tesla’s NMC. For example, a North Carolina homeowner reported 23% faster winter degradation with Powerwall 3 versus competitors. How do you future-proof such investments? Always demand third-party performance validation.
How did Megapack’s success impact Powerwall?
Tesla reallocated manufacturing resources to Megapack production, which delivered 28.8% gross margins versus Powerwall’s estimated 19% in 2025. The shift reflects soaring demand for utility-scale storage, with U.S. deployments growing 199% year-over-year.
Practically speaking, building one Megapack (3.9MWh) generates revenue equivalent to 289 Powerwalls. With Texas Megapack factories hitting 40GWh annual capacity, Tesla prioritized high-volume contracts like Google’s 750MWh Arizona data center project. But what about residential commitments? Installers report 12-week Powerwall delivery delays since Q4 2024, forcing customers to accept competitors’ 2-week lead times. This table illustrates resource allocation shifts:
