Polycrystalline solar panels are made up of multiple crystalline structures which are joined together, giving the panels a unique look and an increased efficiency in terms of energy production. Compared to monocrystalline panels they typically have a lower output but offer a higher resistance to intense sun exposure and a longer life span, with the potential of producing electricity years after they have been installed.
What is the difference between monocrystalline and polycrystalline solar panels?
Monocrystalline and polycrystalline solar panels are two of the main types of photovoltaic (PV) panels used in solar energy systems. Although both types convert sunlight into electricity, their construction differs, resulting in some important differences in terms of performance and cost.
Monocrystalline Solar Panels: These are the oldest and most established type of solar cells. They are composed of silicon ingots that have been cut from a single cylindrical crystal. This results in a uniform color and appearance, which is one of the dead giveaways to tell them apart. Efficiency of monocrystalline solar cells is generally higher than other technologies, and they work well even in low light conditions. However, they also tend to be one of the more expensive options and are not as durable to mechanical damage as other types of solar panels.
Polycrystalline Solar Panels: Polycrystalline solar cells are typically made from melted silicon pieces, instead of forming an individual crystal like monocrystalline cells. This is a much faster and cheaper process and so these types of panels are usually the top choice for residential solar systems. They tend to be slightly less efficient than monocrystalline panels, but the difference is minor. On the plus side however, they are usually cheaper, lighter, and more tolerant of high temperatures.
