What are Polycrystalline Solar Panels?
Polycrystalline panels are relatively new. They start out similar to monocrystalline panels in that a silicon crystal is placed in a vat of molten silicon.
However, instead of drawing the crystal up from the vat as it’s done for monocrystalline manufacturing, the vat is simply allowed to cool. This is what gives the polycrystalline the distinctive edges and grains in the solar cell.
PolyCrystalline Solar Panels Development
For years, this way of manufacturing was thought to make panels less efficient in power. In some ways, it does. However, the manufacturing costs of polycrystalline are much cheaper and reduce waste of the original silicon.
In 2015, Trina Solar set a record when they were able to manufacture polycrystalline cells that operated with 21.25% efficiency. This meant they could produce multiple cells that work at 18-20% efficiency, something that was previously thought to be impossible.
This now means, as technology gets better, polycrystalline panels are slowly becoming closer to working at the efficiency of monocrystalline panels.
