Monocrystalline solar panels are made up of single crystal silicon that is melted into an ingot and thinly sliced. This creates a more refined, more efficient, but also more expensive product. Monocrystalline solar panels are a great choice for homes where roof space is limited since they’re so efficient. They usually appear black in color.
Polycrystalline panels are made up of lots of silicon crystals melted together. They’re not quite as efficient as monocrystalline panels, but they’re also more affordable. If you have plenty of space, this may be a good choice for your home. Polycrystalline solar panels will appear dark blue.
