What are the disadvantages of solar-powered aircraft?

The Solar Impulse 2 solar aircraft is a long-range solar aircraft that can fly continuously day and night without consuming a drop of fuel. The energy required for flight is provided entirely by solar cells. Its wingspan reaches 72 meters, second only to the largest commercial airliner A380 (79.75 meters), but its weight is only about 2,300 kilograms, which is equivalent to a semi-family car.

What are the advantages of the solar plane?

Solar planes also have many shortcomings: solar cells are still very expensive, and the cost of the plane is high (weestimates the cost of just solar cells for a single-seat solar plane (thousands of dollars); the efficiency is still too low, the generated power is limited, and it cannot work at night and on cloudy days. Therefore, many problems need to be resolved before solar-powered aircraft can enter the practical stage. Currently, scientists are already studying a new type of solar cell. Perhaps in the near future, solar-powered planes will have more power, carry more weight and fly faster, higher and further.

Japan and the United States have successfully developed an aircraft using solar cells. Its main wings, fuselage and tail are all equipped with amorphous solar cells, which provide flight power. The plane has a range of 1,500 kilometers and a speed of 64 kilometers per hour. This plane is a one-point propeller gliderds total of 90 kilograms. The body of the aircraft is made of carbon fiber. The fuselage is 7 meters long and the main wing is 17.5 meters long.
