- Monocrystalline solar panels are those PV panels in which the cell is made of a single silicon crystal. These are sometimes referred to as “mono solar panels.”
- Polycrystalline solar panels: Each PV cell is made of multiple silicon crystal fragments that are melded together during manufacturing. You may see them called “multi-crystalline panels” or “poly panels.”
Monocrystalline Solar Panels
Polycrystalline Solar Panels
Polycrystalline solar panels have blue-hued PV cells with straight edges. They have a lower efficiency compared with monocrystalline cells, which means you need more panels to reach the same power output. However, polycrystalline panels also have a lower price, since their manufacturing process is simpler.
Polycrystalline panels are very durable, but they tend to last slightly less than monocrystalline panels. They are also affected more by high temperatures, which reduces their productivity on the hottest days.
Polycrystalline solar panels are more affordable, but monocrystalline panels are more productive. If you have access to a solar loan with favourable interest rates, you can finance your solar installation and pay the loan off with the money you save on utility bills. In this case, the extra cost of monocrystalline solar panels won’t be an issue.
Also, make sure you compare several solar quotes. Monocrystalline solar panels are more expensive individually, but you must also consider other system components and installation costs. There may be cases in which a completed installation with monocrystalline panels is actually cheaper, even if a single panel costs more.
