At present, in many high-end cars, solar sunroofs have begun to use, it can be said that it is the most "approachable" new technology used in mass production cars.
The solar sunroof is provided with a solar battery under the glass of the sunroof of the automobile. The solar battery is connected with the input end of the control unit, and the input end is connected with the temperature sensor of the vehicle air conditioning system. At the same time, the input end is also connected with the battery and the igniter. The solar cells under the glass absorb solar energy, and the battery sunroof can be charged by the sunroof control unit to ensure that the battery's electrical energy is sufficient and the service life of the battery is prolonged.
The most direct benefit of solar skylights for consumers is that, in summer hot weather, cars are parked and stopped in the hot sun. When there is no energy supply, the interior temperature can be automatically adjusted. Solar panels built in the skylights rely on the electricity generated by the sun, through the control system to drive the blower, the cold air outside the car into the car to drive off the car hot air, to achieve the purpose of cooling. When the driver and the occupant reopen the door and sit on the seat, they do not feel hot or sultry. The air conditioning system of the car can reduce the temperature inside the vehicle to a comfortable level in the shortest possible time.
At the same time, it can improve the air condition inside the car, and in winter it can also reduce the frost on the front windshield of the car. According to statistics, the temperature in the car's cab with solar skylights is reduced by up to 20°C compared to models without ventilation. The use of solar power, energy saving and cooling, has effectively reduced the "islanding" effect caused by heat inside the car.
Currently, some of the models sold in China are equipped with solar sunroofs, but not all solar sunroofs can achieve the desired cooling effect. Some models of solar sunroof can use solar energy to operate the blower when the sun is sunny, and exchange the air inside and outside the car, which does not consume electrical energy and other energy. However, the ventilation of the living car and the heating of the car need to consume battery power, and the car heating also consumes. Part of the fuel. Some solar sunroofs only provide part of the energy to the sunroof system. Solar sunroofs will not give any additional support when they are parked.
As a clean, pollution-free renewable energy source, solar energy has been widely used in various industries. It can be foreseen that the automotive solar sunroof will further improve and enhance its functions as technology advances. In the future cars, we will not only see solar sunroofs, perhaps solar roofs, solar cars, etc., but the use of new technology in this car will also gradually move from luxury cars to ordinary family cars. Maybe In the near future, more and better solar energy technologies can also appear on our own cars.
