Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar industry, a new product trend is emerging. Solar panels with Bifacials take sunlight from both their front and rear. They offer a unique solution for certain kinds of solar installation.
What are Bifacial Panels?
The mono-face panels (traditional) are able to capture sunlight in one direction. Light solar energy that is not captured is reflecting back. Bifacial solar panels do not have this problem. Instead, they are equipped with solar cells on both sides. The panels are able to absorb light from both in the back and front. This is why a bifacial panel will absorb light which has been bounced off the ground or another materials.
Certain residential structures like pergolas and ground-mounted systems, could benefit from solar panels that have bifacial faces. For most property owners however, rooftop installations with Bifacial solar panels aren’t feasible. Instead panels that are elevated and angled away from a mounting surface permit light to reflect back into the panels.
How does a Bifacial Solar Panels work?
The panels absorb light from the front and back sides which allows for the diffusion of light to be as large as it is possible. The term “albedo” refers to the portion of sun’s light that is reflecting off a surface. It can reach 30% efficiency, and is influenced by several variables like the reflectivity of the surface as well as the height above ground, and tilt angle. Diffused light is the scattered light that can travel in any direction. The bifacial panels can absorb direct sunrays and reflected radiation from solar panels nearby. It also absorbs diffused indirect radiation from air particles or clouds.
Bifacial solar panels come fitted with a glass-to-glass construction. These panels offer longer-term durability over the mono-face modules with a glass-to-back sheet structure that was previously offered. There are many options for photovoltaics made of thin film in the present. This includes copper indium gallium selenide (CIGS) and dye-sensitized photovoltaic cells. Many current thin-film solar technology including CIGS, or dye-sensitized cells, can be easily transformed into bifacial solar panels.
Bifacial solar panels have the rear cover glass, and a bifacial solar cell. Later, the unabsorbed photon inside the front layer will be slowly absorbed as it recoils from its surrounding surface. This improves the effectiveness of bifacial solar cells. Glass-to glass structures bring many benefits to solar panels, including decreased moisture corrosion, the development of cracks and debonding. They also have a lower cell temperature, and a lower degrading rate. Bifacial solar panels tend to be less flexible, however they do have high physical strength and fireproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to generate electricity directly from the sun.
- These panels can produce electricity by absorbing the light that is passing through them.
- Bifacial solar panels can be constructed of transparent or dual tempered back sheets. This is different from the transparent back sheets.
- The possibility of degradation caused by the sun isn’t an issue for bifacial solar panels.
- The warranty for solar panels with bifacial design is nearly 30 years. This is in contrast to the 25-year warranty on traditional solar panels.
- The bifacial solar panel’s glass can help to reduce the exposure to UV and also improves 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 of Bifacial solar panels aren’t included. They don’t require grounding. This saves time and material during installation costs.
Bifacial Solar Panels: The disadvantages
- The huge installation of Bifacial Panels cost.
- Double glass is the primary reason for the high cost of solar panels with bifacial facets.
- Glass is a heavyweight.
- Bifacial solar panels are not used during the night, cloudy days, or in storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels feature a single photovoltaic side that absorbs light and transform it into renewable energy. Bifacial solar panels are able to absorb sunlight from both sides and are smaller in size.
Bifacial panels perform better than traditional panels as they have more surface area to absorb sunlight. Vertically arranged bifacial panels can capture sunlight at sunset and sunrise. Panels that are mounted vertically can withstand weather conditions conditions such as sun and snow which may hinder their effectiveness. The longevity of bifacial solar panels are also higher than that of traditional panels.
Monofacial panels could still offer certain advantages However, there are many other reasons monofacial panels might be better than bifacial panels. Bifacial panels can be more complicated than other types and require extra work and equipment. They are much more effective than panels mounted vertically however homeowners might have to pay more for ground mounts. Additional requirements , such as solar tracking systems are required.
Bifacial Solar Panel Design
Bifacial panels differ from conventional monocrystalline and polycrystalline silicon panels. Although bifacial panels typically are comprised of monocrystalline cells, they are also polycrystalline options. Bifacial panels can be distinguished by their thin profile. A lot of bifacial designs need only limited framing. The modules themselves are protected by an extremely thin layer of transparent. This could be an opaque back or a dual-glass sheet.
Bifacial solar panels mounting systems are different from traditional solutions. Bifacial solar panels need the least shaded area on their back and front surfaces to capture the maximum amount of solar energy. To lessen the shade on the back of the module, new rack designs can make use of smaller support rails as well as junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panel usage is ideal for utility and commercial installations that utilize solar trackers. Texas Solar Group, a producer of solar panels discovered that solar panels with bifacial symmetry created eleven percent higher solar output when used in the tilted and ground-mounted solar system in China. A system with bifacial panels and solar tracker produced 27 % more solar power than traditional panels.
Because they absorb more energy from both sides, bifacial solar modules can boost the output of energy of large-scale solar farms. A solar panel mounted above the ground can take in sunlight, and reflect it into solar cells that are oriented backwards. The surface beneath will affect how much or little light is reflected back onto the panels. Reflected sunlight is more intense on surfaces with lighter colors like sand, than on darker surfaces, like asphalt or dirt.
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 with reflected sunlight.
Bifacial panels can be used in residential situations, but they’re best suited for commercial or utility-scale solar power systems in the solar industry. Bifacial panels can be used to shade structures that are freestanding such as pergolas and generate excess energy. If the panels are not directly viewable, bifacial panel panels could also be used. Bifacial solar panel canopies and awnings allow reflective sunlight to hit the backs of panels.
Bifacial panels are a good option for those who prefer a ground-mounted system to a rooftop one. A residential ground-mounted system works similarly to commercial or utility applications. It is raised above the ground in order for sunlight to reach the panels the backsides.
Five Reasons Bifacial Panels are ideal for farms
- There is more space
Ground mounts are more suitable to ensure the highest production of bifacial panels. Ground mounts are able to be placed farther away from roof mounts. To make the most of space roof solar panels usually placed in a flush position next to one another. If the array is higher than the ground, such as an awning, there won’t be a lot of reflected light from the back side of the panels.
Businesses in rural areas and farms have more land available which allows for you to spread out your bifacial panel to take full advantage of the ground reflection.
You can also regulate the amount of light reflected. Your panels will be exposed to more light if they have a reflective surface such as white rocks, sand or some other white or silver material.
Ground mounts may also be used for other purposes. They could be used as a covering for your yard or porch or as carports. If you’re fascinated by the idea of bifacial-solar be sure to research every option.
2. More Durable
Farmers and companies involved in agriculture must be certain that the solar panels they install will last for a long period of time. This ensures that they will continue to produce high-efficiency solar panels for several decades.
Bifacial panels last longer than standard one-sided panels that have back sheets. They have glass faces on both sides. Tempered glass is used for the glass. It is extremely durable and can withstand any force that is thrown at it, even projectiles from the force of hurricanes.
3. Longer Warranties
Texas Solar Group, a Bifacial panel maker, provides a 30-year warranty. This is five years longer than the 25-year warranty that some manufacturers provide for single-sided panels.
Your bifacial panels will produce more energy per panel and last longer.
4. In Every Way, Trackers are Better than Trackers
Trackers can be a means of increasing solar output per panel. Trackers adjust their angle on solar panel to align with the sun’s position in the sky. This lets you get more direct sunlight, and will last longer.
Trackers are made up of many moving parts. As with any appliance or mechanism, there are many moving parts that can create problems. Trackers are more costly and take longer to set up.
While the cost of installing trackers that use traditional panels is lower than that of Bifacial panels, they will yield similar quantities. There are no moving parts and you do not need to be concerned about them breaking.
5. Like regular solar cells.
As you might think, bifacial solar panels are higher priced than regular ones in most cases. Texas Solar Group has a solid relationship with Canadian Solar, and we use them exclusively to obtain bifacial solar panels at prices that are very comparable to regular panels.
Texas Solar Group can offer ground-mounted solar panels that have bifacial panels at a similar price to conventional panels for farms that want to increase their production.
For a similar price, you get better production and quality. This is the highest quality you can ask for.
Texas Solar Group can often reduce their upfront costs through grants or federal credit. Combining this with the faster production of bifacial panels can ensure that you can quickly make a profit on the investment.
Tariff exemptions on Bifacial Panels
Over the last several years tariffs on equipment as well as solar panels have had a major impact on the sector. Trump imposed tariffs on non-domestically produced solar panels in 2018. The tariffs were aimed to boost growth in the US’s solar manufacturing and production sector. This limited access to solar panels for a lower price.
These tariffs have been maintained under the Biden administration since taking over the presidency. In fact, they decided to extend them by 4 more years in 2022. But, they took an important choice by exempting bifacial panels from the tariffs. This is a crucial decision for consumers as they can access cheaper panels.
Are bifacial panels worth the investment?
Although bifacial solar solar modules are a good alternative for commercial and utility solar builders, they don’t make sense for rooftop residential projects. Bifacial solar panels are more costly than the equipment needed for residential rooftops, which means homeowners be required to shell out more for them. However, they offer greater effectiveness and savings. However big your project is, the location it is situated, or what other factors you might have to consider, getting multiple quotes for solar panel installation is a good option to secure a fantastic bargain. Join the Texas Solar Group solar pv market, and you will begin getting quotes from licensed solar installers that have been pre-screened in your local area.
