I've heard that a lot of people are using a new type of solar panel. What is it and where can I get one?

That would be a thin-film solar panel. It’s made up of layers of semiconductors, like silicon, but instead of being in the form of a flat wafer, they’re in the form of a thin film. The advantage of this is that it's much thinner than traditional panels, which makes them easier to install. They also tend to be more efficient at converting sunlight into electricity.
