Sure; that's what I do. But a solar panel that will fit on top of a car won't charge very fast. Mine gives about 200 watts best case, and so would take 80 hours of sunlight to completely recharge the car. (Which has an electric-only range of 40 miles.)What if you put them on the roof of a car? Will it work?
А встречный ветер можно использовать для зарядки автомобиля?Sure; that's what I do. But a solar panel that will fit on top of a car won't charge very fast.

It generally makes a lot more sense to put the solar on (for example) a shade structure over a parking lot.
Not easily. But you can certainly sail a car just like you sail a boat, as long as the wind is coming from the sides. But that needs a sail of course.Can headwind be used to charge a car?
Я имела ввиду, что когда автомобиль быстро движется, то встречный воздух по силе давления сопоставим с сильным ветром. Это можно как-нибудь использовать для подзарядки?Not easily. But you can certainly sail a car just like you sail a boat, as long as the wind is coming from the sides. But that needs a sail of course.
Nope. You will need more engine power to push the wind turbine through the air, and that power will always be more than the turbine produces.I meant that when the car is moving fast, the oncoming air is comparable in pressure to a strong wind. Can this be used for recharging somehow?
A wind turbine that deploys when parked (using natural wind) or used during braking and folds away at other times would hypothetically charge the vehicle when not in use and recover some energy from change in momentum as it slows a moving vehicle. Otherwise it takes engine power to overcome the greater wind resistance from the vehicle pushing the wind turbine against the air.I meant that when the car moves quickly, the oncoming air is comparable in strength to the strong wind.

You appear to have a fundamental misunderstanding - you are either not accounting for the wind resistance ("drag coefficient'') component of a wind turbine mounted on a moving object or greatly underestimating it. Conservation of energy applies - it always does - but adding up the individual components of energy flows to confirm it in such an application (that includes wings/sails/turbines involving fluid flows) can be complex.
Ну, я же сразу сказала, что понятия не имею, как устроен электромобиль. У нас в стране это редкость, в основном все предпочитают обычные бензиновые или дизельные. Я видела такие солнечные батареи скомбинированные с ветряками, на домах. Их используют для получения электроэнергии. Стоит это в среднем примерно 500$ по курсу за 1 квт.ч. Т.е., если вам нужно чтобы установка вырабатывала 10 кв.ч., вам нужно купить оборудование за 5000$. Гарантия на них 40 лет, производят у нас на Урале. В автомобилях, наверное, совсем другая система.A wind turbine that deploys when parked (using natural wind) or used during braking and folds away at other times would hypothetically charge the vehicle when not in use and recover some energy from change in momentum as it slows a moving vehicle.
