Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar market an exciting new trend in solar products is emerging. Solar panels with Bifacials take sunlight from both their front and rear. They provide a novel solution to certain kinds of solar installations.
What are Bifacial Panels?
Mono facial panels (traditional) take in sunlight only in one direction. Light solar energy that is not captured is reflect back. Bifacial solar panels do not have this problem. Instead, they feature solar cells on both sides. The panels are able to absorb light both from the front and back. This means that a bifacial panel can absorb light that has been reflected off of the ground or other materials.
Some residential applications like pergolas and ground-mounted systems, could benefit from Bifacial solar panels. For most property owners, rooftop installations that incorporate bifacial solar panels won’t be feasible. Instead panels that are raised and set away from a mounting surface can let light reflect back onto the panels.
How does a Bifacial Solar Panels work?
The panels reflect light from the front and back sides and allow to diffuse light as much as it is possible. Albedo light refers to the part of the sunlight that is reflected off of a surface. It can reach 30% efficiency, and is influenced by several factors such as the reflectivity of surfaces on ground as well as the height above ground, and tilt angle. Diffused light is the scattered light that can travel in any direction. The bifacial panel can absorb direct sunrays and reflect radiation from solar panels nearby. It can also absorb diffused indirect radiation from air particles or clouds.
Bifacial solar panels come equipped with a glass-to glass structure. They provide longer-term reliability than the mono-face module with back-to-glass sheet construction that was previously offered. There are numerous photovoltaic technologies that are thin-film in the present. They include copper indium selenide (CIGS) and dye-sensitized photovoltaic cells. The majority of current thin-film solar technologies including CIGS, or dye-sensitized, are easily converted to bifacial solar panels.
Bifacial solar panels are made up of front cover glass as well as a bifacial solar cell. The photon that is not absorbed within the front cover glass will be absorbed slowly when it is released away from the surface. This improves the effectiveness of the Bifacial solar cells. Glass-to-glass structures offer numerous advantages for solar panels, such as reduced moisture corrosion, propagation of cracks, and debonding. They have a reduced cell temperature and a slow degrading rate. Bifacial solar panels are more flexible, yet they possess a high mechanical strength and flameproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to generate electricity directly from sunlight.
- These panels are able to generate electricity using the reflective light passing through them
- Bifacial solar panels may be constructed of transparent or dual tempered back sheets. This is different from the transparent back sheets.
- Degradation that could be caused by sunlight isn’t an issue with solar panels with bifacial faces.
- The warranty on Bifacial solar panels lasts for almost 30 years. This is different from the warranty of 25 years for conventional solar panels.
- The bifacial solar panel’s glass can help to reduce UV exposure and moisture permeability.
- The modules are shielded against chemical corrosion because of their strong construction.
- The panels are constructed of solid glass that is impervious to cracking.
- The aluminum frames that make up the bifacial solar panels are not included. They do not require grounding. This can save time and materials for installation costs.
Bifacial Solar Panels: The disadvantages
- The huge installation of Bifacial Panels cost.
- Double glass is a major reason for the cost of solar panels that have bifacial faces.
- Glass is very heavy.
- Bifacial solar panels are not utilized during evening, on cloudy days, or in storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels have one photovoltaic surface that can absorb light and transform it to renewable energy. Bifacial solar panels can be able to absorb light from two sides, and are smaller in size.
Bifacial panels work better than conventional panels due to the fact that they have more surface area to absorb sunlight. Bifacial panels that are vertically mounted can catch sunlight at sunrise and sunset. Panels that are mounted vertically are more resistant to weather, such as sun and snow, which can reduce their efficiency. The longevity of bifacial solar panels are much higher than traditional panels.
Monofacial panels can still provide some benefits however there are numerous other reasons why monofacial panels could be more beneficial than bifacial. Bifacial panels may be more complicated than others and require extra work and equipment. They are better than horizontally mounted ones, but homeowners may pay more because they require ground mounts. Additional requirements , such as sensors for solar energy are needed.
Bifacial Solar Panel Design
Bifacial panels are significantly different from traditional monocrystalline and polycrystalline silicon panels. Although bifacial panels are typically composed of monocrystalline cells, there are also polycrystalline options. Bifacial panels stand out due to their thin profiles. A lot of bifacial designs need only minimal framing. The modules are protected with an extremely thin layer of transparent. It could be an opaque back or a dual-glass sheet.
Bifacial solar panels ‘ mounting systems are different from traditional solutions. Bifacial solar panels require the least shaded area on their front and back surfaces to maximise solar energy capture. To minimize shading on the modules’ backsides, new racking solutions can use smaller support rails as well as junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panel use is ideal for utility and commercial installations that utilize solar trackers. LA Solar Group, a producer of solar panels discovered that bifacial solar panels generated 11 percent more solar energy a tilted or ground-mounted system of solar in China. A system using bifacial solar panels and solar tracker produces 27 % more solar power than one using traditional panels.
Since they absorb more energy from both sides, bifacial modules can boost the output of energy of large-scale solar farms. Solar panels that are placed above ground can reflect sunlight and absorb it into solar cells backwards. The surface beneath will affect the amount of light that is reflected back to panels. Reflected sunlight is more intense on lighter surfaces, such as sand than on darker surfaces like dirt or asphalt.
Can you use bifacial solar panels for residential installations?
Bifacial modules don’t suit rooftop solar installations. They are more cost-effective for larger solar projects that have reflected sunlight.
Bifacial panels can be employed in residential areas, but they are most suitable for commercial or utility-scale solar power projects in the solar sector. Bifacial panels are able to shade free-standing structures such as pergolas and produce excess energy. In all cases where the panels are not directly visible, bifacial panels may also be used. Bifacial solar panel canopy and awnings permit reflection of sunlight onto the backs of panels.
Bifacial panels are an excellent option if you prefer a ground-mounted system over rooftop ones. Ground-mounted systems for residential use work similarly to utility or commercial applications. It is elevated above ground in order for sunlight to penetrate the panels the backsides.
- There is also more space
Ground mounts are ideal for the best manufacturing of bifacial panel. Ground mounts can be set further away from roof mounts. To maximize the area, roof solar panels usually placed in a flush position next to each other. In the event that the panel is taller than the ground, for example, an awning, then there won’t be a lot of reflected light from the back side of the panels.
Farms and other rural businesses are able to use more land, which means you can extend your bifacial panel to maximize the benefits of reflectivity on the ground.
You also have the option of controlling the amount of light that is reflected. The panels will be more exposed to light if they have a reflective surface like white rocks, sand or some other white or silver material.
Ground mounts can be used for other purposes. They could be used as a covering for your yard or porch, or as a carport. If you’re looking into the concept of bifacial solar ensure you research every option.
- More Durable
Farmers and companies involved in agriculture must be sure that their solar panels are durable for an extended time. It is a guarantee that they will continue to make efficient solar panels for many decades.
Bifacial panels last longer than standard one-sided panels that have back sheets. They feature glass facings each side. Tempered glass is utilized for the glass. It is extremely tough and can withstand any force, including projectiles from hurricane force winds.
- Longer Warranties
LA Solar Group, a manufacturer of bifacial panels, offers the 30-year guarantee. It’s five years more than the 25-year warranty that several manufacturers offer for one-sided panels.
The bifacial panels you have will generate higher energy output per unit, and will last longer.
- In Every Way, Trackers are Better than Trackers
Trackers are a method of increasing solar output per panel. Trackers adjust the angle of solar panels in accordance with the position of the sun on the sky. This allows you to enjoy more direct sunlight, and will last longer.
Trackers have many moving parts. As with any appliance or mechanism they have many moving parts that can create problems. Trackers can be more expensive and take longer to install.
Although the price of installing trackers that use traditional panels is lower than those with Bifacial panels, they will still produce similar amounts. There aren’t any moving parts and you do not have to worry about them breaking.
- Similar to normal solar cells
Like you would think, bifacial solar panels are more expensive than regular ones in the majority of cases. LA Solar Group has a close relationship with Canadian Solar, and we make use of them exclusively to purchase Bifacial solar panels for sale at prices that are quite similar to standard panels.

LA Solar Group can often lower their initial costs with grants or federal credit. In combination with the speedier production of bifacial panels can ensure that you can quickly make a profit on your investment.
Tariff exemptions on Bifacial Panels
In the past few years, tariffs on equipment and solar panels has had a significant impact on the solar industry. Trump has imposed tariffs on foreign produced solar panels in 2018. These tariffs were designed to spur expansion in the solar production and manufacturing. This restricted the availability of solar panels at cheaper prices.
These tariffs have been maintained through during the Biden administration since taking over the presidency. In fact, they decided to extend them by 4 more years , beginning in 2022. But, they took an important decision in exempting bifacial panels of the tariffs. This is a crucial decision for consumers as it allows them access to cheaper panels.
Are bifacial panels worth the investment?
Although bifacial solar solar modules are an excellent alternative for commercial and utility solar builders, they won’t perform well on rooftop residential projects. Bifacial solar panels are more costly than the equipment required for residential rooftops, which means homeowners need to pay for them. They do however offer better efficiency and lower costs.
