Which is Better Bifacial Solar Panels vs Monofacial Solar Panels?

bifacial solar panels
The use of solar panels has become increasingly popular as a way of generating electricity without contributing to environmental degradation. However, there are different types of solar panels available in the market, with varying characteristics and efficiency. Two of the most common types are bifacial and monofacial solar panels. In this article, we will discuss the differences between these two types of solar panels and help you decide which is better for your needs.

What are Bifacial Solar Panels?

Bifacial solar panels are a type of solar panel that can generate electricity from both sides of the panel. These panels are made of a transparent layer on the backside, allowing sunlight to pass through and reflect off the surface underneath, thereby increasing the amount of light absorbed. Bifacial solar panels can be installed in various ways, including elevated on a tracking system or on a fixed mount.

What are Monofacial Solar Panels?

Monofacial solar panels are the most common type of solar panel and generate electricity only from one side. They are made of a single layer of photovoltaic cells, which are usually silicon-based, and are covered with a protective layer of glass or plastic. Monofacial solar panels can be installed in various ways, including rooftop, ground-mounted, or building-integrated.

Bifacial vs. Monofacial Solar Panels

There are several factors to consider when deciding which type of solar panel is better for your needs. Some of these factors are: Efficiency: Bifacial solar panels are typically more efficient than monofacial solar panels because they can generate electricity from both sides. In some cases, bifacial solar panels can produce up to 30% more electricity than monofacial solar panels. Cost: Bifacial solar panels are generally more expensive than monofacial solar panels due to the added cost of the transparent layer on the backside. However, the extra cost can be offset by the increased efficiency of bifacial solar panels. Installation: Bifacial solar panels require more care during installation than monofacial solar panels because they need to be installed on a suitable surface to reflect sunlight to the underside of the panel. Additionally, they may require specialized mounting hardware and tracking systems to ensure optimal performance. Maintenance: Both bifacial and monofacial solar panels require minimal maintenance. However, bifacial solar panels may require more frequent cleaning due to the reflective surface on the backside, which can attract more dirt and dust.


In summary, both bifacial and monofacial solar panels have their advantages and disadvantages. Bifacial solar panels are more efficient but are more expensive and require more care during installation. Monofacial solar panels are less expensive and require less care during installation, but they are less efficient. Ultimately, the decision of which type of solar panel to use will depend on your specific needs and budget. It is recommended that you consult with a solar panel installation professional to help you make an informed decision.
