Solar Roof Product Discontinued Due to Low Market Share
Tesla officially discontinued its Solar Roof glass solar tiles in August 2026. Launched in 2016, this flagship product completed approximately 3,000 installations in the US market, accounting for just 0.17% of residential solar installations in 2022. Tesla stated that this product line adjustment is part of a broader shift in its solar strategy, aimed at concentrating resources on products with greater market potential.
The Solar Roof struggled to break through market barriers since its launch due to high costs, complex installation processes, and difficulties in scaling. Despite Tesla positioning it as a symbol of green technology, its actual market performance fell far short of expectations. In contrast, Tesla’s global energy business revenue reached $12.8 billion in 2025, a 27% year-over-year increase, driven primarily by its Megapack large-scale energy storage systems and Powerwall home batteries, with rooftop solar systems contributing minimally.
In-House Solar Panels Debut: 420-Watt Product Emphasizes Performance and Integration
In January 2026, Tesla launched its first fully in-house designed and manufactured 420-watt solar panel at Gigafactory Buffalo in New York. The product features an all-black design and integrated mounting structure, with Tesla highlighting its ability to maintain high power generation efficiency even in shaded conditions. When paired with the Powerwall 3 energy storage system, it forms the core of Tesla’s residential energy solutions.
The Powerwall 3 integrates a battery and solar inverter, simplifying the installation process while enhancing power outage protection and peak electricity price management. Tesla’s online design tool defaults to a configuration of solar panels plus Powerwall 3, underscoring the company’s focus on energy storage. The launch of these new products is seen as a key move to revitalize Tesla’s residential solar market.
Major Shift in Installation Model: Third-Party Certified Installer Network Expands to 35 Countries
In September 2024, Tesla began recruiting third-party "Certified Installers," gradually transitioning installation operations to external partners. By 2026, Tesla’s network of certified installers had grown to over 7,000 across more than 35 countries, completing over 1 million installations. This shift marks Tesla’s transition from direct installations to a hybrid model, focusing on hardware manufacturing and software platform management.
According to Tesla’s official documentation, installation services are now divided into two models: in Tesla’s direct service territories, the company handles sales and installations; in other regions, certified installers provide quotes, installations, and after-sales service. All processes are managed through the Tesla One software platform to ensure consistent service standards. However, Tesla has not publicly disclosed the specific scope of its direct service territories, requiring consumers to use an online tool and input their address to determine which installation model applies.
This change reflects Tesla’s redefinition of its role in the solar market. Installation operations have thin profit margins, high labor costs, and challenges in scaling, so outsourcing allows Tesla to focus on hardware sales and home energy management software development. The discontinuation of the Solar Roof aligns with this logic, as the product never surpassed a 1% market share, and its retirement helps consolidate resources.
Pricing and Financing Options: Lease Restrictions Raise Consumer Concerns
Tesla’s solar systems are priced at approximately $2.30 per watt in cash (excluding installation and incentives) and offer several standardized financing options: solar loans at 7.24%, Powerwall loans at 6.99%, and leases at 8.5%. However, the 25-year solar lease (12 years for Powerwall) is only available in Tesla’s direct service territories and includes a 3% annual price escalator. Due to varying utility company incentives across states, Tesla encourages consumers to use its address-based quote tool to avoid prematurely disclosing service territories.
The new model offers convenience but also introduces some uncertainties. Since Tesla has not clearly defined its direct service territories, consumers must proceed deep into the quoting process to confirm their installation method. Additionally, the quality of service from third-party installers may vary by region, potentially impacting the overall user experience. As US electricity prices continue to rise, demand for solar energy is increasing, but the price and service quality of Tesla’s systems will depend on the professionalism of its installers.
Tesla emphasizes its continued commitment to the US solar market, though its future growth will rely more heavily on its partner network. The success of this new strategy will hinge on the execution capabilities of third-party installers and Tesla’s ability to maintain a competitive edge in hardware manufacturing and software platforms.
