Aptera Exceeds Solar Charging Expectations During Real-World Validation Testing

About this update from Aptera Motors Corp.

CARLSBAD, Calif., June 25, 2026 (GLOBE NEWSWIRE) -- Aptera Motors Corp. (Nasdaq: SEV), a solar mobility company pioneering ultra-efficient transportation, today announced a key internal validation milestone: its solar electric vehicle has achieved more than 4 kilowatt-hours (kWh) of daily solar energy generation under real-world conditions in Southern California. The result validates a long-standing thesis and objective that Aptera had previously set based on simulation and panel testing. Now, for the first time, a production-intent validation vehicle has registered the metric under real-world conditions, topping out at 4.42 kWh of total daily generation. Based on Aptera's efficiency design target of 100 watt hours per mile, the vehicle generated enough solar energy to travel up to 44 miles on that day. "For years, we've said solar can meaningfully contribute to everyday transportation," said Steve Fambro, Co-Founder and Co-CEO of Aptera. "These results exceeded our expectations and demonstrate what's possible when solar technology is integrated into a vehicle designed from the ground up for efficiency." At the heart of Aptera's solar is a custom solar charge controller featuring many independent channels that continuously optimize energy collection across the vehicle. This performance is the result of a system Aptera designed and built from the ground up, from the compound-curved panel architecture, to a proprietary solar charge controller with custom firmware, to the vehicle's power distribution architecture. That full-stack ownership is what made it possible to optimize every layer of the system simultaneously and validate it as a complete unit. Aptera has published a breakdown of solar data from multiple days of testing on their blog , and released an accompanying video on their YouTube channel . To provide independent verification of these findings, Aptera has engaged a third-party laboratory to formally validate its solar system and rate its performance. That testing is scheduled to take place within the next month, with results to be shared upon completion. This milestone advances Aptera's vehicle validation program ahead of customer deliveries.
