When choosing solar panels, one of the basic decisions to make is about technology. Do you prefer Poly-crystalline or Mono-crystalline modules? Our customers often ask about the difference between polycrystalline and monocrystalline modules, and so - we have put together this Monocrystalline vs. Polycrystalline infographic to explain the main differences and provide some guidance.
The main differences between polycrystalline and monocrystalline modules are their efficiency and price. Monocrystalline modules are more efficient, but also slightly more expensive.
Another difference is their color: Monocrystalline modules are black, and polycrystalline modules are blue. This leads to an aesthetic difference (monocrystalline modules looks good in an all-black system), and also to a performance difference in warm areas. Since black absorbs heat more easily, and since solar cell efficiency is reduced at high temperatures, polycrystalline modules will be slightly less affected by high temperatures.
In the six years that have passed since we originally wrote this article, the price of monocrystalline modules has come down significantly. While polycrystalline modules are still preferred when system cost needs to be held to a minimum, a lot of people prefer the aesthetics and features of modern monocrystalline modules.
