1 Solar cars

Solar cars are vehicles that use photovoltaic (PV) panels to convert sunlight into electricity, which is then stored in batteries or used to power an electric motor. Solar cars can either be fully solar-powered, meaning they rely only on the sun for energy, or hybrid, meaning they can also use other fuels or plug into the grid. Solar cars are still mostly experimental or used for competitions, but some companies and researchers are working on making them more practical and affordable for everyday use.

Solar cars, integrating photovoltaic panels for power, are making strides in real-world applications. Hyundai’s Sonata Hybrid and Toyota’s Prius Prime models in North America and Europe feature solar roofs for auxiliary power. The Lightyear 0, a Dutch innovation, stands out, offering significant solar-powered range and functioning as one of the earliest solar electric vehicles focused on solar-driven mobility. These developments mark significant progress in the transition towards sustainable transportation, blending solar energy with electric vehicle technology.

2 Solar buses

Solar buses are buses that use solar energy to reduce their fuel consumption and emissions. Solar buses can have different designs, such as rooftop PV panels, solar trailers, or solar charging stations. Some solar buses are fully electric, while others are hybrid or use solar power to supplement diesel or natural gas. Solar buses can offer lower operating costs, less noise and air pollution, and better passenger comfort.

A real-life example of solar buses in use can be seen in the initiatives undertaken by various global manufacturers and regions. Companies like BYD, Proterra, Solaris, and Yutong are key players in the market, offering different types of solar buses, including fully electric and hybrid models. These buses are increasingly adopted in regions with higher solar exposure, such as Mainland China, which leads the global electric bus market. In China, about 30.1% of the bus fleet as of 2023 comprises electric buses, many of which are supported by solar energy.

3 Solar trains

Solar trains are trains that use solar energy to power their locomotives, carriages, or stations. Solar trains can either use direct or indirect solar power. Direct solar power means that the train has PV panels on its roof or along the tracks, which feed electricity to the train or the grid. Indirect solar power means that the train uses electricity from solar farms or plants that are connected to the grid. Solar trains can reduce greenhouse gas emissions, fossil fuel dependency, and grid congestion.

4 Solar boats

Solar boats are boats that use solar energy to propel themselves on water. Solar boats can have different configurations, such as catamarans, ferries, or yachts. Solar boats usually have PV panels on their decks or sails, which charge batteries or power electric motors. Solar boats can also have backup generators or hybrid systems for cloudy days or emergencies. Solar boats can offer zero-emission, low-maintenance, and quiet navigation.

5 Solar planes

Solar planes are aircraft that use solar energy to fly in the air. Solar planes can have different shapes and sizes, from small drones to large gliders. Solar planes usually have PV panels on their wings or body, which provide electricity to the propellers or the jet engines. Solar planes can also have batteries or fuel cells to store excess energy or provide backup power. Solar planes can enable long-duration, high-altitude, and emission-free flights.

6 Solar challenges

Solar-powered transportation systems face several challenges, such as low efficiency, high cost, limited availability, and variable weather conditions. Solar power depends on the intensity and duration of sunlight, which can vary depending on the location, season, and time of day. Solar power also requires large surface areas and advanced materials to capture and convert enough energy to move heavy vehicles. Solar power also competes with other sources of energy, such as fossil fuels, biofuels, or hydrogen, which may have lower costs or higher performance.
