In the solar market, new key product innovation is emerging. Bifacial solar panels are an intriguing new option for some solar systems, which can absorb sunlight from both the front and back ends.
Traditional solar panels, sometimes called mono-facial panels, can only absorb light from one surface, losing any remaining light energy. Contrarily, bifacial solar panels differ from typical ones in that they have solar cells installed on both sides. This process assists the solar panel in absorbing solar radiation from both sides, which increases energy consumption.
What are Bifacial Solar Panels?
Bifacial solar modules do not have the same drawbacks as conventional solar panels. A bifacial panel increases overall electricity generation by producing power from both sides. Since both sides are UV-resistant, they are often more durable. Potential-induced degradation (PID) risk is also reduced when a bifacial solar panel is physically sound. The price of the balance of the system (BOS) decreases when more electricity is made available.
Bifacial panels generate more power from the backside when positioned on a vividly clear surface (such as a white TPO ceiling or ground covered in light-colored pebbles, for example). This additional electricity production can lead to cleaner, more efficient, and 30% higher productivity.
A variety of bifacial module designs are available. In addition to two main bifacial types, we offer solar twin-cell and BIPV ranges. Some of them are mounted, but not all of them. Others have transparent back sheets, while some even have dual-glass back sheets. Although polycrystalline variants are also available, crystalline silicon cells are most frequently employed. Unfortunately, the power generated by both sides continues to be a constant.
There are also other types of panels that reveal the back of the cells, such as frameless or dual glass modules. These cells are still not regarded as bifacial, though. On the front and back sides of the cells, there are bus bars that make up the actual bifacial panels.
The mono-facial solar panels are arranged in parallel racks on the rooftop. However, if the bifacial panels are positioned at various or inclined angles from the ground, they will generate more energy.
Bi-facial solar panels have numerous commercial uses, including pergolas and specific ground-mounted systems.
Industrial or communication infrastructures are the most incredible places to use these bifacial panels. The panels are inclined and tilted away from a mounting surface, allowing light to reflect onto the panel. Bifacial solar panels are now equally as efficient as conventional solar panels since they take up less space and offer greater efficiency.
Additionally, bifacial solar panels are particularly effective when used for industrial purposes. Compared to traditional panels, transparent surfaces offer clean and efficient energy.
How Can Bifacial Solar Panels Be Installed to Increase Efficiencies?
Let’s first explore the configuration of a mono-facial solar array to comprehend the differences. A system of one-sided solar panels known as a mono-facial solar panel system is set up in racks parallel to a surface, like a rooftop. Bifacial solar panels are positioned on a tilt instead of single-sided ones because they generate more energy when tilted off the roof or the ground at different angles.
The bifacial solar array installation offers three benefits:
1. Taking in more sunlight
There is a lot of introspection in these kinds of themed installations. Bifacial solar panels can collect more sunlight because they reflect off all objects at various angles.
2. Effective on cloudy days
Bifacial solar cells can be effective on overcast days due to the argument mentioned above; however mono facial solar cells suffer more when there isn’t direct sunshine. Additionally, because bifacial are more robust, they are less vulnerable to weather damage.
3. A day with two energy peaks
Based on its placement, a named installation may also result in two energy peaks throughout the day. For instance, an array’s half of the bifacial can be oriented toward the east to catch the dawn and early morning light. The second half can then be angled toward the west to witness the strength of the late-afternoon sun.
A vertical installation is another option for doing this. The solar panels’ opposite sides will reflect sunlight during each peak, adding to the energy generated.
What is the Increase in Efficiency of a Bifacial Solar Array?
When we talk about efficiency, we’re talking about the process by which a solar cell transforms the solar energy it has absorbed into electrical energy. However, bifacial panels generate more electricity than mono-facial ones; they are not yet twice as efficient, although solar panel makers are attempting to change that. A study found that bifacial systems can increase energy efficiency by 11% when compared to conventional solar panel systems. Additionally, when combined with a solar tracking system that continuously tilts solar panels toward the sun, bifacial solar cells’ efficiency can approach 27%.
Advantages of Bifacial Solar Panels –
Improved performance: It is the most crucial aspect. Bifacial panels generate more energy overall since they may generate power from both sides of the panel. Traditional solar panels cannot produce as much electricity as bifacial solar panels. Some manufacturers assert that the additional power generated from the rear will enhance output by 30% when the modules are installed on a highly reflecting surface.
Durability: Bifacial panels are frameless, in contrast to traditional mono-facial panels. They are frequently more durable since the tempered glass is applied to both sides. Tempered glass can tolerate high temperatures, powerful winds, and adverse weather conditions. It is also UV resistant.
PID, or reduced potential-induced degradation: Results from electrical currents deviating from their intended course. They damage the solar panels as a result. Unframed bifacial panels are used (without any metal). Consequently, there is a lower risk of potential-induced deterioration of the solar cells (PID). Furthermore, bifacial panels don’t need to be grounded because the exterior lacks metal contacts.
Works Better in Diffused Light: The bifacial panel has the additional benefit of performing better in diffuse light than mono-facial panels, owing to the increased surface area. These panels are, therefore, affordable when considering long-term costs.
Final Thoughts
Bifacial solar panels guarantee a cutting-edge method of energy consumption by showcasing superior performance by maximizing electricity production levels through clean energy generated during the sun’s rising and setting cycles. Examine your roof, available installation space, finances, and energy usage habits before choosing this clean and sustainable energy source to ensure that your investment is appropriate.
