Can solar energy car have wind power combine together to give us extra energy?
Yes, but you only get to combine their energies when both sunlight and wind are available. If wind is calm or blowing the wrong way, the solar cells must do more work to carry the extra load of sail. If the sun ain’t shining, the sails must drag the extra weight of solar panels. The best solution is to use the solar panels as sails when the wind blows and make them more streamlined when the wind is unfavorable.
