A Comprehensive Guide to Bifacial Solar Panels

Another substantial product development is taking place in the solar business. Bifacial Solar Panels can collect light from both the front and back ends, are a promising new solar option for some solar systems.

Traditional solar panels are also referred to as mono facial panels since they can only absorb light from one surface, wasting the light energy that is not absorbed. On the other hand, bifacial solar panels are distinct from ordinary panels in that they have solar cells on both sides. This technique aids in the solar panel’s absorption of solar radiation from both sides, resulting in increased energy consumption.

What Are Bifacial Solar Panels ?

Bifacial solar panels are double-sided panels that gather and transform solar energy from both the top and bottom sides.

They’ve been around since the 1970s when they were originally utilized in the Soviet space program, but they were too expensive to construct on a large scale.

The good news is that manufacturing them is now a lot less expensive, which means that regular people like you can already get them.

Bifacial panels are typically significantly smaller and frameless than monofacial panels. Protective glass covers the top of each panel, while the backside is either glass or a clear back sheet.

Why Use Bifacial Solar Panels ?

Traditional single-sided solar panels have several advantages over bifacial solar panels .

They’re ideal if you’re short on space, for example. They provide greater solar energy for the same size solar panel and only slightly higher installation expenses.

Bifacial modules are often raised from the surface since they are meant to collect sunlight from both sides. As a result, there’s a lower danger of them overheating.

Another benefit is that they’re usually more durable because both sides are UV-resistant.

The fact that you may install bifacial panels in a variety of combinations is perhaps the most intriguing feature for you.

They may be tilted at various degrees and utilized as ground mounts or raised mounts on flat roofs with success. This means that bifacial panels can be used in both commercial and residential settings.

Finally, bifacial panels may be beautifully integrated into various aesthetic and architectural components such as canopies, pergolas, and sun-breakers because they are transparent and very slim.

How Does A Bifacial Module Work?

A bifacial solar panel’s top solar cells face the sun, allowing them to directly absorb the available sun rays. In this way, it’s similar to a traditional solar panel.

The cells at the bottom, on the other hand, are designed to absorb reflected light. This means that when angled to a white roof or the ground, bifacial panels produce more energy than standard one-sided panels.

Even better, because bifacial panels are all about light reflection, they work even better on foggy days when the light is already diffused.

You can use this to your advantage by tilting half of your panels east and the other half west. As your panels capture both morning and afternoon rays, you’ll be covered for the entire day.

Simultaneously, the backsides of the panels do their part by soaking up the solar energy that “comes” from the other side.

Your bifacial can also be positioned vertically. This system also provides two energy peaks each day and during each dismal, with the reflected light harvested on the backside.

How Are Bifacial Solar Panels Installed?

Depending on the type of solar panel, bifacial solar panels are fitted. Because standard solar modules are already modified for framed models, installing a framed bifacial solar panel is easier than installing a frameless one. Most bifacial panel manufacturers, on the other hand, offer their clamps with their products, making installation very simple. When it comes to frameless solar panel versions, the clamps are frequently equipped with rubber protectors to protect the glass. Installers must be careful not to overtighten the bolts and harm the glass while installing this type of panel.

The higher the angle of a bifacial solar panel, the more energy it produces. That’s why it’s best to use it on the flat rooftop or ground-mounted arrays with plenty of room for tilting and reflected light to bounce back to the module’s back end.

Finally, you should be aware that the performance of your bifacial panels is influenced by the supporting structure.

The bottom-side bifacial cells will be shaded by mounts with support rails that are covered by the backplate of a single-facial module.

This is why you should use mounting and racking systems built specifically for bifacial installations.

Bifacial vs Monofacial: How Efficient Are Bifacial Solar Panels?

The ability of a solar cell to convert the complete amount of solar energy into electrical energy is the efficiency of solar panels.

According to a 2018 study conducted by LONGi Solar, bifacial solar systems can enhance efficiency by 11% over standard solar panels.

SunPower Performance bifacial panels’ latest iteration incorporates aviation-grade conductors for cell connections, providing even more gains while optimizing the active area. Over the next 25 years, these technical changes will save around 32% more energy.

Is it possible to improve their efficiency even more?

Yes, if you use a solar tracking system that keeps tilting solar cells toward the sun as it moves across the sky, you can increase their productivity by as much as 27 percent.

By keeping the panels perpendicular to the sun at all times, such a system is continually looking for maximum direct exposure.

More monofacial panels would be required to obtain the same quantity of solar power.

The true effectiveness of various types of solar panels, on the other hand, is dependent on your latitude.

Because these places have low reflected light, or albedo light, monofacial solar systems are more cost-effective at latitudes below 40°.

Bifacial solar systems, on the other hand, work better in latitudes above 40 degrees.

Bifacial can increase energy production by up to 71 percent at latitudes above 65°.

How To Know If Bifacial Solar Panels Are Right For You

To determine whether you can profit from bifacial solar, first assess the surface reflectivity or albedo potential of your site, as well as the available tilt angle.

Metal and white roofs are excellent reflectors, so if you have one, bifacial is a must.

Because snow is one of nature’s most reflecting elements, if you live in a region with a lot of snow, you should consider a bifacial ground mount.

What’s the best part? Even if their top side is covered in snow, Bifacials will continue to generate electricity. The more vertical your bifacial panels are, the more light and energy they may create on the backside. If you have a level roof or enough space in your garden for a ground mount, bifacial panels may be the best option.

If you’re still undecided, fill out this little survey. If you answered “yes” to at least two of these questions, a bifacial system is ideal for you.

  • Do you have space for a ground-mount system on your property?
  • Is there snow cover on your property for most of the year?
  • Is there a sandy area on your property? (Would you create a mini-desert?)
  • Would you like to create one or several pergolas or awnings?
  • Is your roof white or silver or could you paint it or cover it with white or silver shingles?

What’s The Future for Bifacial Solar Modules?

Experts agree that in the coming years, bifacial solar modules will likely dominate the industry.

The new era of solar will favor high-efficiency bifacial modules built using high-end components, according to the technical director of Chinese solar panel producer LONGi Solar.

Although bi-facial systems are slightly more expensive than monoracial modules, the power boost you’ll obtain with bifacial modules more than makes up for the difference.

According to a 2019 analysis by Wood Mackenzie Power & Renewables, the cost of bifacial panels is expected to drop by 23% in five years.

If you’re looking for a cheaper green energy option, keep this in mind.

Conclusion

Bifacial solar panels are well worth the investment. Solar cells on the backside boost the amount of power you can collect by capturing sunlight that reflects off the roof or the ground.

Installing bifacial modules on a solar tracking system that maintains them angled towards the sun all of the time will enhance their output.

Another approach to maximize their output is to paint your roof white or use light-colored pavers if you have a ground-mount system, as this increases the quantity of reflected sunlight.
