Dartsolar has introduced its new folding solar roof rack, which boasts 2,000 watts of power and is designed for electric vehicles. This innovative product can extend the driving range by up to 40 miles each day without any cost. This announcement follows the completion of their earlier 1,000-watt model. For those interested, updates and the opportunity to pre-order the 1,000-watt version for $99 can be found on the company’s website. The starting price for these models is $1,950, which varies based on the chosen accessories.

Daily Solar Power Benefits

Most vehicles sit idle for most of the day after just a couple of hours on the road, even in cities with long commutes. States like New York enjoy an average of over nine hours of sunlight daily, which means the solar roof rack can provide a significant boost in range on a daily basis.

Power Generation Details

When deployed, the 2,000-watt solar panels are fully exposed to sunlight, while 360 watts are available when the rack is folded during travel. The unit can produce as much as 10 kWh of energy each day, translating to a range of 40 miles for electric vehicles. The smaller 1,000-watt version can yield up to 20 miles of range.

Design and Features

The Dartsolar is intended to be mounted directly onto Tesla roofs or on a roof rack for other electric vehicles. Its construction includes expanding aluminum tubes, 3D-printed components with provided blueprints, and solar panels that are 1/8-inch thick, achieving around 20 percent efficiency. Notably, all components are replaceable, including the solar panels, which can be upgraded to more efficient versions.

The energy harnessed from the solar panels is stored in a battery unit, which can be used along with a compatible charging cable to recharge the electric vehicle, similar to any charging station. Innovative users may find ways to hardwire the system, making it unnecessary to exit the car to connect the charging cable.
