Solar energy is rapidly gaining popularity as a renewable and sustainable power source. Two main types of solar panels are widely used: Monofacial and bifacial solar panels. Both types have their unique advantages and considerations. In this blog, we will explore their feature to help you make an informed decision.
What Are Monofacial Solar Panels?
Monofacial solar panels are the traditional and most commonly used type of solar panels. They consist of a single layer of photovoltaic cells that capture sunlight and convert it into electricity. These panels are typically made of crystalline silicon, the most widely available and cost-effective material for solar cells.
Pros of Monofacial Solar Panels:
Cost-effectiveness: Monofacial solar panels have been in use for many years, and their production processes are well-established. As a result, they are generally more affordable compared to bifacial panels. Monofacial solar panels can effectively harness solar energy from all surfaces without requiring a reflective surface to operate. This characteristic contributes to the reduced cost of these panels.
Lighter weight: In comparison to bifacial panels. As the backside of monofacial panels lacks solar cells, they are not burdened with the additional weight their predecessors carry.
Easy to install: their installation process is easier due to their single-sided light absorption, which can lead to faster installation times and potentially lower labor costs.
What Are Bifacial Solar Panels?
Bifacial solar panels are a newer technology that is gaining momentum in the solar industry. Unlike monofacial panels, bifacial panels have the ability to capture sunlight from both sides. These panels have a transparent back sheet, allowing sunlight to pass through and reach the rear side of the solar cells.
Pros of Bifacial Solar Panels:
Enhanced Efficiency: Bifacial panels offer an efficiency of 11-12%, which is higher than that of monofacial modules. They generate more energy while utilizing fewer resources, making them highly efficient.
Improved Durability: Unlike monofacial panels, bifacial modules exhibit higher durability. They can withstand rough climatic conditions without cracking and are also resistant to heat.
Reduced Space Requirement: Bifacial panels require less installation space compared to monofacial panels. They can produce the same amount of electricity with fewer modules, optimizing land utilization.
Flexible Installation Angles: Bifacial panels can be set up at any angle, eliminating the need for extensive analysis or calculation of mounting and tilt angles. This versatility simplifies the installation process.
No Tracker Needed: Bifacial panels do not require solar trackers, which are devices used to adjust panel angles. This reduces complexity and maintenance requirements. Additionally, bifacial panels often come with a 30-year warranty.
Both bifacial and monofacial panels have their own unique features and drawbacks. When it comes to efficiency, bifacial panels excel, while monofacial panels currently have a more favorable price point.
Final Thoughts
Monofacial panels offer a cost-effective and reliable solution, making them suitable for many applications. On the other hand, bifacial panels offer increased energy production and potential space optimization, making them a viable option for certain environments and installations.
Choosing between monofacial and bifacial solar panels depends on various factors, including your specific needs, location, and budget. So, whether you choose Monofacial or bifacial panels, you’ll be harnessing the sun’s power and positively impacting the environment.
