Thin film solar panels best attribute is in their aesthetics. As their name states, they are very thin and low-profile. Thus is due to the fact that the cells are about 350 times thinner than the crystalline cells. This allows for a wider variety of uses, including RVs, boats, and campers to use them. They come in both black and blue colors, depending on how the cells were made.
Thin film panels will have a lower efficiency and power capacity than poly or monocrystalline panels. It is also cheaper to install a thin film panel as it is less labor intensive.
