Clemson University graduate students have unveiled Deep Orange 17, an electric vehicle prototype designed to generate more energy than it consumes during a standard urban commute. Named Luminetta, the project focuses on capturing solar energy while the vehicle is both driving and parked, demonstrating a different approach to electric vehicle efficiency.
Deep Orange 17 Developed as an Energy-Positive EV
Deep Orange 17 was developed by Clemson University graduate students in collaboration with industry engineers. The project was created after BMW challenged the university to develop an energy-positive vehicle platform.
Rather than relying on standardized driving cycles, the prototype emphasizes real-world use by taking advantage of the time passenger vehicles spend parked in direct sunlight.
More Than 1,700 Solar Cells Power the Prototype
The Luminetta prototype incorporates more than 1,700 photovoltaic cells integrated into its exterior body panels. The system continuously captures solar energy whether the vehicle is in motion or parked.
Developed with the Fraunhofer Institute, the solar panels are designed to continue generating electricity even when portions of the vehicle are shaded.
According to the original report, while some automakers have used solar panels to provide supplemental power, the Clemson team designed the system to serve as the vehicle’s primary energy source.
Lightweight Design Improves Efficiency
The prototype weighs 1,212 pounds and uses a lightweight multi-material chassis constructed from structural steel, aluminum, carbon fiber, and 3D-printed metal joints.
The vehicle also features an aerodynamic design inspired by the boxfish. Researchers tested the prototype across simulated global climate conditions to evaluate its performance.
According to the project, a typical 12-mile daily commute generated enough surplus solar energy to provide an average of 31 additional miles of driving range.
Prototype Scheduled for CES 2027 Debut
The Luminetta will remain at Clemson University’s automotive research center as an ongoing testing platform before making its scheduled public debut at the 2027 Consumer Electronics Show in Las Vegas.
The project required graduate students to oversee the complete vehicle development process while working within real-world budgets, schedules, and technical requirements.
Deep Orange 17 demonstrates Clemson University’s approach to developing an energy-positive electric vehicle through lightweight construction, integrated solar technology, and real-world engineering testing.
