According to Sawyer Merritt, Tesla has unboxed its new residential solar panel featuring a 420W output—an increase from the previous 410W model. The panel, which adopts the same cascading cell technology as Tesla's Solar Roof, is designed to sit closer to the roof and offers an all-black finish for improved aesthetics. Notably, it creates 18 distinct power zones, tripling the segmentation found in conventional panels. As reported by Sawyer Merritt, this advancement could drive more efficient solar energy generation and streamlined integration for smart home energy management solutions.
