Which type of solar panel is best: monocrystalline or polycrystalline?
When it comes to buying solar panels for your home, there isn’t a lot that obviously differentiates one solar panel from other. If you buy a car, there’s dozens, if not hundreds of different features, styles, and add-on options that you can take into account.

When you’re shopping for solar panels, one of the things that manufacturers usually tout is efficiency. A high efficiency panel turns more sunlight into electricity than a lower efficiency panel, which means a solar homeowner can get more out of their limited rooftop space. So if efficiency is a good thing, that must mean that you should shop for the highest efficiency panels you can get, right? No, not always. If you’re in a situation where it’s important to maximize your power generation - like if you have a small roof - then efficiency could be very important to you.
