Solar powered cars are battery powered cars. The solar array is charging the batteries. So there is no real difference.
yes
only if you need to listen to music for a short amount of time. A hand crank powered boom box, will charge faster than a solar powered one, so you can listen almost instantly. A solar powered one would be better for a long term usage like working outside while painting your house.
Solar powered cars are shaped differently because 1. The cars need to be aerodynamic to move faster, and 2. The shape collects more sunlight to power the car
Solar powered lights are lamps with small solar panels mounted on top that recharge a usually triple AAA (not included) Ni-Cad battery. The light is a LED which uses very little juice and in theory will last for months maybe even years. It depends on where you live in that rainy areas cause the battery to corrode onto the contacts. Other than that a cheap alternative to outside lighting
Solar powered radios will last far longer than wind-up radios, provided there is adequate sun.
Battery powered remote control cars are more efficient and economical.
I wouldn't choose 1 over the other, but I will say that they need to be together for the best results. Chances are, People in you country may be using solar energy as well as batteries to power their machines. Battery powered toys are mobile and will not need a plug, however, they do have a limited battery life and they will contribute to global warming! Solar powered toys operate without plugs and are (again) mobile. The best part is, the Panels generate power in a clean way, which means you will not contribute to the shortage of fossil fuels. The problem is, if the solar power toy does not receive any type of waves (mostly visible light), they will instantly run out of power. When I say, "They need to be together for best results", I am saying that a solar powered toy that includes a rechargeable battery can be convenient for you and the people around the globe. Think about it, your toy will last forever if you have light in your home (as long as it doesn't wear out), because the solar panels will constantly charge the rechargeable battery and when there is no light (lets say the power when out temp.), you have a battery to last you for a few days. In conclusion, solar panels and rechargeable batteries are meant to be together and should never be separated for your sake and for the world! So if there's an option for both, that would be my answer!
they are faster, louder and can kill a child alot quicker than a duracell powered car
there not no power or noise
No, not possible.
Any normal laptop whose battery is recharged by a solar panel rather than a standard charger would be a solar powered laptop. Due to the limited amount of power available from light (from the Sun) with modern panels, compared to a computer's required input, it may be necessary to use a number of low-powered alternatives to conventional parts, and to avoid (energy inefficient) electric cooling systems when less energy-consuming alternatives are available.
If the 12 volt solar panel output voltage is always higher than the 6.5 watt battery voltage. To charge a battery, a voltage greater than the battery must be applied to the battery, otherwise the battery will try to charge the charger.
