Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar market an exciting new trend in solar products is emerging. Bifacial solar panels are solar panels that absorb 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) capture sunlight only on one side. Solar energy that is not captured is reflect back. Bifacial solar panels do not suffer from this issue. Instead, they feature solar cells on both sides. The panels are able to absorb light from both their front as well as back. This is why a bifacial panel can absorb light that was bounced off the ground or any other materials.
Certain residential structures, such as pergolas or ground-mounted systems can benefit from solar panels that have bifacial faces. For most property owners, however, rooftop installations with bifacial solar panels won’t be feasible. Instead panels that are elevated and set away from a mounting surface{ will|| can} allow light to reflect back into the panels.
How does a Bifacial Solar Panels work?
The panels reflect light from the sides facing forward and back, allowing for the diffusion of light to be as large as possible. The term “albedo” refers to the part of the sun’s light that is reflecting off of a surface. It is able to reach 30 percent efficiency and is dependent on a variety of variables like the reflectivity of surfaces on ground in relation to height above the ground, as well as tilt angle. Diffused light is scattered light that passes through any direction. The bifacial panel can absorb direct radiation from the sun and reflect radiation from solar panels nearby. It is also able to absorb indirect diffused radiation from air or clouds.
Bifacial solar panels are also equipped with a glass-to glass structure. These panels offer longer-term durability than the mono-face module with glass-to-back sheet structure which was previously available. There are a variety of photovoltaic technologies that are thin-film today. This includes copper indium gallium selenide (CIGS) and dye-sensitized photovoltaic cells. A lot of the current technology for solar thin-film including CIGS, or dye-sensitized, can easily be converted to bifacial solar panels.
Bifacial solar panels come with the rear cover glass, and a the bifacial solar cell. Later, the unabsorbed photon inside the front layer will be absorbed slowly when it is released from the surrounding surface. This boosts the effectiveness of 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 as well as a slower rate of degradation. Bifacial solar panels are more flexible, yet they possess a high mechanical strength and a flameproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to produce electricity directly from sunlight.
- These panels can produce electricity by absorbing the light that is passing through them.
- Bifacial solar panels can be constructed from transparent or dual-tempered back sheets. This differs from opaque back sheets.
- Degradation that could be caused by sunlight isn’t a concern with solar panels with bifacial faces.
- The warranty for bifacial solar panels is almost 30 years. This is in contrast to the 25-year warranty on the traditional panels.
- The bifacial solar panel’s glass can help to reduce UV exposure and moisture permeability.
- The modules are protected from chemical corrosion due to their high strength.
- The panels are made from solid glass that is impervious to cracking.
- The aluminum frames of the Bifacial solar panels aren’t included. They do not require grounding. This saves time and material for installation costs.
Bifacial Solar Panels: The disadvantages
- A huge installation of bifacial panels cost.
- Double glass is the primary reason for the high cost of solar panels that have bifacial faces.
- Glass is a heavyweight.
- Bifacial solar panels cannot be utilized during dark, cloudy days or in storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels are made up of one photovoltaic side that absorbs sunlight and convert it to renewable energy. Bifacial solar panels{ can|| are able to} take in sunlight on both sides, and require less space.
Bifacial panels are more efficient than conventional panels due to the fact that they have more surface to absorb sunlight. Vertically arranged bifacial panels can capture sunlight at sunset and sunrise. Panels that are vertically mounted can withstand weather conditions such as snow and sun, which can reduce their efficiency. The longevity of solar panels with bifacial facets is also higher than that of traditional panels.
Monofacial panels can still provide some benefits However, there are many different reasons why monofacial panels may 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 but homeowners could have to pay more for ground mounts. Additional requirements such as the solar tracker system are necessary.
Bifacial Solar Panel Design
Bifacial panels differ from traditional monocrystalline and polycrystalline silicon panels. Although bifacial panels typically are composed of monocrystalline cells, there are polycrystalline alternatives too. Bifacial panels stand out due to their slim profile. Many bifacial designs require the use of a limited frame. The modules themselves are protected in an extremely thin layer of transparent. This can be either a dual-glass or clear back sheet.
Bifacial solar panels mounting systems differ from traditional solutions. Bifacial solar panels require the least shaded area on their front and back surfaces in order to capture the maximum amount of solar energy. To lessen the shade on the back of the module, new rack solutions are able to use more narrow support rails and junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panel usage is perfect for utility and commercial installations that make use of solar trackers. Shneyder Solar, a producer of solar panels discovered that bifacial solar panels produced an increase of 11 percent in solar power in a tilted and ground-mounted solar system in China. A system with bifacial panels and a solar tracker generated 27 percent more solar energy than traditional panels.
Because that they take in more power from the two sides of their body, bifacial modules can increase the energy output of massive solar farms. A solar panel mounted above the ground can reflect sunlight and absorb it into solar cells in the opposite direction. The surface below will influence the amount or how much light is reflected back onto the panels. Reflected sunlight will be more intense on lighter surfaces like 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’re more affordable for larger solar installations that use reflection of sunlight.
Bifacial panels are able to be utilized in residential settings, however they are best suited to large-scale commercial and utility scale solar energy projects in the solar power industry. Bifacial panels can be utilized to shade free-standing structures such as pergolas and generate extra energy. In all cases where the panels aren’t directly visible, bifacial panels can be utilized. Bifacial solar panel canopy and awnings allow reflective sunlight to hit the backs of panels.
Bifacial panels can be a great option for those who prefer a ground-mounted system over an on-roof one. A residential ground-mounted system works exactly the same way as utility or commercial applications. It is elevated above surface to allow sunlight to get to the panels their back sides.
Five Reasons Bifacial Panels are ideal for farms
- There is also more space
Ground mounts are more suitable for the best manufacturing of bifacial panel. Ground mounts can be placed further away from roof mounts. To make the most of the space available, roof solar panels usually placed in a flush position next to one another. When the solar arrays are taller that the floor, such as an awning, then there won’t be a lot of reflected light coming off the back of the panels.
Farms and other rural businesses are able to use more land, which allows for you to extend your bifacial panels in order to maximize the benefits of reflectivity on the ground.
You can also control the amount of light reflected. Your panels will be exposed to more light if they have reflective surfaces like white rocks, sand or some other silver or white substance.
Ground mounts can be used in other ways. They could be used as a cover for your yard or porch, or as carports. If you are interested in the bifacial-solar concept, make sure to investigate all options.
2. More Durable
Farmers and companies involved in agriculture need to be sure that their solar panels will last for a long time. It is a guarantee that they will continue to produce high-efficiency solar panels over the course of many years.
Bifacial panels are stronger than standard one-sided panels that include back sheets. They feature glass facings on both sides. Tempered glass is the material used to make the glass. It is extremely strong and can withstand any force, including projectiles from hurricane force winds.
3. Longer Warranties
Shneyder Solar, a Bifacial panel maker, provides 30 years of warranty. This is five years more than the warranty of 25 years that some manufacturers provide for single-sided panels.
The bifacial panels you have will generate greater energy for each panel and last longer.
4. In Every Way the Trackers are better than Trackers in every way.
Trackers can be a means to increase solar power per panel. Trackers adjust angles of solar panels to match the sun’s position at the top of the sky. This allows you to get more direct sunlight, and will last longer.
There are many moving parts in trackers. As with all appliances and mechanisms there are more moving parts which can create problems. Trackers are more costly and take longer to set up.
While the cost of installing trackers that use traditional panels is less than{ that of|| those with} Bifacial panels, they yield similar quantities. There are no moving parts and you do not need to be concerned about breaking them.
5. Similar to normal solar cells
As you’d expect, bifacial panels are more expensive than regular ones in the majority of cases. Shneyder Solar has a solid relationship with Canadian Solar, and we use them exclusively to obtain bifacial solar panels at prices that are very similar to standard panels.
Shneyder Solar can offer solar panels for ground mounted with Bifacial panels for a similar cost to conventional panels for farms looking to increase their production.
For the same cost, you can get higher production and quality. This is the most you can get.
Shneyder Solar can often lower their initial costs with grants or a federal credit. This, when combined with the quicker production of bifacial solar panels will guarantee that you will be able to quickly make a profit on the investment.
Tariff exemptions on Bifacial Panels
In the last few years tariffs on equipment as well as solar panels has had a major impact on the sector. Trump put tariffs on non-domestically produced solar panels in the year of 2018. The tariffs were aimed to encourage expansion in the solar production and manufacturing. The tariffs impeded access to solar panels at a lower price.
These tariffs have been imposed under the Biden administration since taking its presidency. In fact, they decided to extend them by 4 additional years starting in 2022. However, they made an important decision by exempting bifacial panels of the tariffs. This decision is crucial for consumers as they can access cheaper panels.
Are bifacial panels worth the investment?
While bifacial solar panels can be a great option for utility and commercial solar developers, they don’t work well for residential rooftop projects. Bifacial solar panels are more costly than the equipment that is required, so homeowners will still be required to shell out more for these panels. But they provide greater efficiency and lower costs. No matter how large your project is, the location it is situated or any other requirements you may have when comparing quotes for solar panel installations can be a great way to find a great bargain.
