## Questions & Answers

**Q: Do you get enough materials to make all four, or do you have to break down one to build another?**
A: Hi, you don't have to break down one to build another, each piece of all four set is individually packaged, which includes all the materials to complete. So you can do it one by one without breaking your previous successful projects.

**Q: What is the power output of each of the solar panels?**
A: Hi,Mindiraser
The solar car is 2 V 260 mA, and each panel of solar fan is 1.5 V 160 mA (the max power under standard light). 
The actual current and voltage are related to the light conditions
Thank you very much!
CYOEST

**Q: Does the car move from the wind created by the fan, or does the motor turn the wheels to drive the car?**
A: Hello, the car with the red fan is moving by the wind created by the fan.
I sincerely hope I can help you!
Thank you very much!

**Q: will these operate/work by flashlight for indoor use?**
A: Hello, solar panels can only work in direct sunlight, 
light through glass, dark clouds, flashlights, indoor lights all DO NOT work.
Thank you for your question and have a nice day!
