Different types of Solar Panels

Let’s talk about the basic types of solar panels and how they’re used.
•Monocrystalline silicon (mono-silicon or single silicon)

Right now, these are the most efficient type of solar panels. In other words, when sunlight hits these puppies, more of it turns into electricity than the other types below. As a result of their high silicon content, they’re also more expensive, but you need fewer of them. That’s why they’re ideal for roofs. You can tell if you have a monocrystalline solar panel by its square-ish cells.

•Polycrystalline silicon (multicrystalline, multi-silicon, ribbon)

“Poly” panels have lower silicon levels than “mono” panels. In general, that makes them less expensive to produce, but they’re also slightly less efficient. The good news is that their overall construction design can often make up for the efficiency loss, so they’re also good for roofs. You can tell poly-silicon panels by their groovy mélange of silicon woven through thin rectangular conduit wires.

•Thin film (amorphous silicon, cadmium telluride, copper indium gallium (di)selenide)

Thin film solar panels are very inefficient, which means you’ll see them in big solar farm projects with a lot of land, but not on your roof.
