I'm doing a science project, and one site states that they are different, while other sites use "solar panels" and "photovoltaic panels" interchangeably. So are they the same thing, or are they different?
If they're different, how do they differ?
Thanks!
Oh, okay. Thanks!
Are there any solar panels that heat up air, too?
