Polycrystalline solar panels are cheaper to produce than monocrystalline panels, which allowed them to make up a significant market share in residential installations between 2012 and 2016. Solar panels (Mono or Poly crystalline) are created from multiple ‘wafers’ of silicon connected together in series and/or parallel to form a solar ‘module’. A 100 Watt monocrystalline panel and a 100 Watt polycrystalline panel will both output 100 Watts, neglecting power loss in the system, but a monocrystalline panel will output 100 watts with a smaller surface area. Mono-crystalline panels are created from a single silicon crystal, either found naturally (very rare) or grown in a laboratory. The main difference between the two technologies is the type of silicon solar cell they use: monocrystalline solar panels have solar cells made from a single crystal of silicon, while polycrystalline solar panels have solar cells made from many silicon fragments melted together. To get around this, we surveyed module prices to compare the price difference between monocrystalline and polycrystalline panels. The wafer is then fried at a few hundred degrees celsius to create contact between the silicon and the metal electrodes. As suggested by the name, a monocrystalline panel is created from a single crystalline structure. Polycrystalline panels have about 13 to 16% efficiency, while monocrystalline panels have an efficiency rate of anywhere from 15 to 20%. What is the difference between Mono-crystalline and Poly-crystalline? Manufacturers melt the silicon and pour it into a mold to create a square. Which one is better? Couple that with their lower price and it is no wonder they are the more popular choice. This is due to the fabrication process. Another similarity between polycrystalline solar panels and mono-crystalline solar panels is that they are both made from the same material, that is silicon and it is quite durable. The yellow bar is monocrystalline panels. Monocrystalline panels are the oldest and most used solar panel technology. Monocrystalline, as their name suggests, have cells made from a single crystal of silicon. For this reason, if maximising electricity generation and reducing costs is a priority, monocrystalline are likely to be slightly more effective.
