"The new Tesla Solar Panel and mounting system pairs with the company’s inverter, Powerwall battery, EV charging and vehicles, creating an all-Tesla residential solar offering for the first time. While Tesla has been a dominant player in storage with the Powerwall, a market leader with its inverter, and in EVs, the company has historically relied on third-party solar panels. With the launch of the Tesla Solar Panel (TSP-415 and TSP-420), the company is closing that loop. Tesla's new modules, assembled at its Gigafactory in New York, represent a significant shift toward a proprietary, integrated ecosystem designed to solve the common rooftop challenges of shading, aesthetic clutter, and installation friction. “This panel completes the full package of the residential energy ecosystem,” said Colby Hastings, senior director, Tesla Energy. “It is based on our long history of innovation and engineering when it comes to solar.” Tesla's Buffalo, NY facility is currently scaling to an initial capacity of over 300 MW per year.
