Monocrystalline vs. polycrystalline solar panels FAQs

  • When deciding which type of solar panel to buy, you’ll have to consider your budget and the quality you want. While monocrystalline panels are more efficient, they are also more expensive.

  • Monocrystalline solar panels are more efficient and, therefore, can provide a greater return on your investment. As a result, they are typically considered the best solar panel choice. They are the best choice for a surface with a limited room because they produce more electricity in a smaller space than polycrystalline panels.

  • The main difference is that monocrystalline solar cells are made with single-crystal silicon, while polycrystalline panels are composed of multiple silicon fragments. The cell structure makes monocrystalline panels more efficient than polycrystalline types.  

  • Monocrystalline and polycrystalline solar panels are the most popular options. But they aren’t the only ones. Thin-film panels are another option. Made of glass, metal, or plastic, thin-film panels are typically lighter and more malleable. But they are much less efficient than crystalline silicon solar cells, which means you’d need more thin-film panels to reach the energy production level of silicon-based panels.
