Which Solar Panels Are Best: Mono or Poly?

Monocrystalline (mono) solar panels are made from a single silicon crystal, while polycrystalline (poly) solar panels are made from multiple silicon crystals. Mono panels are known for their higher efficiency and sleeker appearance, while poly panels are typically less expensive and easier to manufacture.

Monocrystalline solar panels have a higher efficiency rating because they are made from a single crystal of silicon, which allows for more efficient electron movement. This means that they can produce more power in a smaller amount of space. They also tend to have a longer lifespan, lasting up to 25 years or more.

Polycrystalline solar panels, on the other hand, have a lower efficiency rating because the multiple crystals in each cell can interfere with electron movement. However, they are typically less expensive than monocrystalline panels, making them a more budget-friendly option for some consumers.

In general, both types of solar panels can be a good choice depending on your specific needs and budget. If you have limited space on your roof or want the highest efficiency possible, then monocrystalline panels may be the better choice. If you're looking for a more budget-friendly option and have more space available, then polycrystalline panels may be the way to go.
