Munich-based solar mobility OEM Sono Motors made two world premieres at its first “Celebrate the Sun” community event “Sion”, the world’s first solar electric car for the masses, debuted in its production design and “Bus Solar Kit” B2B retrofit solution to enable sustainable mobility for commercial transportation.

Sono ‘Sion’ Solar Electric Car

The Sion will consist of 456 seamlessly integrated solar half-cells and enable self-sufficiency on short journeys.

The energy generated by the solar cells is expected to extend the estimated 305 km range of Sion’s 54 kWh LFP battery to an average of 112 km (up to 245 km) per week.

The battery will allow for a maximum charging capacity of up to 75 kW (DC) and 11 kW (AC). The bidirectional charging technology complements the car’s solar integration and is designed to turn the Sion into a permanent power plant on wheels that can power electronic devices, homes, or other electric cars with an output of up to 11 kW.

Sono “Solar Bus Kit”

The Solar Bus Kit is a versatile and straightforward solution optimized for the most common 12-meter public transport bus types on the European market, including the Mercedes-Benz Citaro and MAN Lion City.

Sono Motors will offer a complete and efficient retrofit solution for bus fleet operators who have an imperative need to reduce diesel consumption and CO2 emissions to meet their sustainability goals.

The Solar Bus Kit allows subsystems such as HVAC to be partially powered by renewable energy thereby saving fuel, CO2, and cost.

The kit can save up to 1,500 liters of diesel per year and 4 tons of CO2 per year from ~1.4 kW peak installation with a total size of approximately 8 square meters of solar panels. Bus fleet operators see a potential payout time of around 3-4 years depending on the days of operation and fuel prices.
