Solar Cell Module

Kay Said:

I have a science question. Look at add details for ?

We Answered:

3v and 0.1amps = 0.3 watts (W = VA)
So, for 60 watts, you'd need 60/0.3 = 200 solar cell modules.

Yvonne Said:

can someone help with this physics question?

We Answered:

3V * 0.1amp = 0.3 watts
5 cm * 8 cm = 40 cm^2
0.3 watts / 40 cm^2 = 0.0075 watts/cm^2
So if we want 40 watts, we need 40 / 0.0075 =~ 5333 cm^2
