The Most Efficient Type Of Solar Panel

Monocrystalline solar panels are the most efficient type of panel; polycrystalline and thin-film solar panels are other common solar panel types that offer lower efficiency. For those looking to purchase solar panels, it’s important to consider both the cost and overall efficiency to determine the type of panel that’s best for you.

Monocrystalline Solar Panel Efficiency

Monocrystalline solar cells are the most efficient and can be used for residential properties as well as commercial installations. These cells are composed of a single crystal of silicon, which is highly efficient compared to cells with multiple fragments of silicon melted together. Their construction also allows them to take up less space. They can be expensive, so they made were not the best choice if cost is your biggest concern.

Polycrystalline Solar Panel Efficiency

Unlike monocrystalline cells, polycrystalline solar cells are comprised of multiple silicon crystals melted together. They typically come with a lower price tag but are less efficient and take up more space than monocrystalline silicon solar cells.

Thin-Film Solar Panel Efficiency 

Thin film solar panels are lightweight, flexible, and inexpensive, but are the least efficient type of solar panel. However, their versatility makes them a great choice for non-rooftop or DIY applications, such as RVs and smaller appliances.

How Solar Panel Efficiency Differs By Product

Given the same amount of sunlight shining for the same duration of time on two high-efficiency solar panels with different efficiency ratings, the more efficient panel will have a higher power output than the less efficient panel.

In practical terms, for two high-efficiency solar panels of the same physical size, if one has a 21% efficiency rating and the other has a 14% efficiency rating, the 21% efficient panel will produce 50% more kilowatt-hours (kWh) of electricity under the same conditions as the 14% efficient panel. Thus, your electric bill savings with solar heavily rely on the efficiency of your solar panels.
