Solar car makes 363W power in morning test, beats home solar
Aptera offered a fresh glimpse into its solar electric vehicle ambitions when co-CEO Steve Fambro shared a real-time comparison that quickly drew attention.
On April 14, he shared that his company’s solar electric vehicle was producing more power than his home rooftop system.
Early morning output tells a story
Posting on X, Fambro wrote, “At this very instant, just after 8:00 am, my house is only making 136W of solar power. Aptera? About 300W!!”
He later showed the vehicle generating 363 watts, compared to just 136 watts from his rooftop panels. While this moment reflects a specific set of conditions, it highlights the design approach behind the solar electric vehicle.
The comparison is particularly relevant because early morning sunlight arrives at a low angle. This is typically when rooftop systems struggle to perform efficiently. In contrast, the car is engineered to capture sunlight from multiple angles, allowing it to produce more power during these hours.
Design advantage under low sunlight
Traditional residential solar panels are installed at fixed angles. They are usually optimized to generate peak output around midday when the sun is highest. However, in the early morning, sunlight hits these panels at an angle, reducing efficiency.
The vehicle from Aptera Motors uses a different strategy. Its solar cells are integrated across the hood, dashboard, roof, and rear hatch. This layout ensures that at least some portion of the surface is positioned to capture direct sunlight at almost any time of day.
The system has a total capacity of about 700 watts. According to the company, it can add up to 40 miles of driving range per day in sunny regions. This capability is being tested in real-world conditions through 2025 and 2026.
The early morning comparison does not mean the car produces more energy overall than a house system. Over a full day, a rooftop installation will still generate significantly more electricity. However, the vehicle’s advantage lies in capturing energy during less optimal conditions.
Financial snapshot and production progress
The update comes shortly after the firm released its latest financial results. The company, now publicly traded on the NASDAQ under the ticker SEV, reported a full-year 2025 GAAP net loss of $43.9 million. On an adjusted basis, the loss was $18.5 million.
For the fourth quarter alone, losses reached $15.5 million. By the end of December, the company held $9.6 million in cash. These figures reflect the typical financial challenges faced by pre-revenue electric vehicle startups.
Despite the losses, operational milestones show progress. On March 3, the company completed its first solar EV from its validation assembly line in Carlsbad. The facility also received Foreign-Trade Zone status in February, which can help reduce costs on imported components. Additionally, the company secured a lease extension through March 2028.
Funding efforts and future outlook
In the first quarter of 2026, Aptera raised about $17.1 million in gross proceeds. This included a $9 million follow-on offering in January and $8.1 million from warrant exercises. A significant portion of that came from a $6.3 million warrant inducement deal in mid-March.
These funds add to a previously secured $75 million equity line of credit, providing the company with additional financial flexibility as it moves toward production.
The early-morning solar data point may seem small, but it reflects a broader goal. Aptera aims to reduce reliance on charging by maximizing energy capture throughout the day. If successful, this approach could change how drivers think about powering their vehicles.
