DartSolar unveils expandable vehicle solar array with up to 2 kW output

DartSolar LLC, based in Los Angeles, has finalized production plans for a vehicle-integrated solar array designed to mount on standard roof racks and truck beds without structural modifications. The system uses modular 500 W units measuring roughly 23 inches by 6 feet when contracted, expanding to 15 feet when deployed. Multi-unit configurations are possible, with two modules generating up to 1,000 W on sedan crossbars and three to four modules producing between 1,500 W and over 2,000 W on larger vehicles like trucks and campers.

The expanding array is intended to supply off-grid electricity for portable power stations, jobsite tools, and auxiliary battery systems rather than serving as a primary EV charging solution. DartSolar estimates daily solar generation could add approximately 10 to 20 miles of driving range to an EV under typical exposure conditions. The system is housed under a 4 mm polycarbonate protective shell to mitigate impact damage from hail and road debris during transit.

High-speed stability testing was conducted at speeds up to 100 mph in standard and lateral configurations, though operational guidelines recommend travel speeds under 70 mph. The array incorporates a multi-angle quick-release locking mechanism to facilitate deployment from different access points around larger vehicles, enhancing usability for varied vehicle setups.

In line with an open-hardware model, DartSolar has released 3D CAD files for structural plastic components under a share-alike license, enabling end users to manufacture replacement parts locally via 3D printing. The company emphasizes durability and modularity, positioning the system as a practical solution for supplemental power needs in mobile and off-grid applications.
