Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar industry there is a new trend of solar panels that is developing. Bifacial solar panels are solar panels that take sunlight from both sides. They are an innovative solution for certain kinds of solar installation.
What are Bifacial Panels?
Panels with mono facial faces (traditional) are able to capture sunlight on one side. Solar energy that is not captured is reflected 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 their front as well as back. This means that a bifacial panel is able to absorb light has been reflect off of the ground or any other material.
Certain residential structures like pergolas and ground-mounted systems, can benefit from solar panels that have bifacial faces. For the majority of homeowners, however, rooftop installations using solar panels that are bifacial won’t be feasible. Instead panels that are elevated and set away from a mounting surface{ will|| can} permit light to reflect back into the panels.
How does a Bifacial Solar Panels work?
The panels reflect light from the back and front sides which allows to diffuse light as much as possible. The term “albedo” refers to the portion of sunlight that is reflected off a surface. It can be as high as 30% efficiency, and is influenced by several factors such as the reflectivity of the surface as well as the height above ground, and tilt angle. Diffused light refers to the scattered light that can travel in any direction. The bifacial panel is able to absorb direct sunrays as well as reflected radiation from nearby solar panels. It is also able to absorb diffused indirect radiation from clouds or air particles.
Bifacial solar panels come equipped with a glass-to glass structure. They provide longer-term reliability over the mono-face modules with a back sheet glass which was previously available. There are many options for photovoltaics made of thin film today. These include copper indium gallium selenide (CIGS) and dye-sensitized photovoltaic cells. The majority of current thin-film solar technologies like CIGS and dye-sensitized cells, can be easily converted to bifacial solar panels.
Bifacial solar panels come with the rear cover glass, and a the bifacial solar cell. The photon that is not absorbed in the front layer will be slowly absorbed as it recoils away from the surface. This improves the effectiveness of the Bifacial solar cells. Glass-to glass structures bring many benefits to solar panels. These include reduced moisture corrosion, propagation of cracks and debonding. They have a reduced cell temperature and a slow decay rate. Bifacial solar panels are less flexible, however they do have high mechanical strength and flameproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to generate electricity directly from the sun.
- These panels are able to generate electricity using the reflective light that is passing through them
- Bifacial solar panels may be constructed from transparent or dual tempered back sheets. This is distinct from transparent back sheets.
- Degradation that could be caused by sunlight isn’t a concern with bifacial solar panels.
- The warranty for Bifacial solar panels lasts for almost 30 years. This is different from the 25-year warranty on traditional solar panels.
- The bifacial solar panels’ glass can help to reduce water permeability and UV exposure.
- The modules are protected from chemical corrosion due to their high strength.
- The panels are made of solid glass that is impervious to cracking.
- The aluminum frames of Bifacial solar panels don’t come included. They don’t require grounding. This can save time and materials in the process of installation.
Bifacial Solar Panels: The disadvantages
- A huge installation of bifacial panels cost.
- Double glass is a major reason for the cost of solar panels that have bifacial faces.
- Glass is a heavyweight.
- Bifacial solar panels can’t be employed during the night, cloudy days, or in storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels are made up of one photovoltaic side that absorbs the sunlight, and then convert it to renewable energy. Bifacial solar panels{ can|| are able to} be able to absorb light from two sides, and require less space.
Bifacial panels work better than conventional panels due to the fact that they have more surface that can absorb light. Bifacial panels with a vertical layout can capture sunlight at sunrise and sunset. Panels mounted vertically have a greater resistance to the elements conditions such as sun and snow which could block some of their efficiency. The longevity of solar panels with bifacial facets is much higher than conventional panels.
Monofacial panels can still provide certain advantages However, there are many other reasons monofacial panels might be better than bifacial panels. Bifacial panels may be more complex than other panels and require extra effort and the use of equipment. They are better than horizontally mounted ones, however homeowners might have to pay more for ground mounts. Other requirements like sensors for solar energy are required.
Bifacial Solar Panel Design
Bifacial panels differ from conventional monocrystalline and polycrystalline silicon panels. Although bifacial panels typically are made of monocrystalline cells there are also polycrystalline options. Bifacial panels are distinguished by their slim profile. Some bifacial designs require only limited framing. 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 need the least shaded areas on their front and back surfaces to maximize solar energy capture. To reduce shading from the back of the module, new racking solutions can use more narrow support rails and junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panel use is ideal for utility and commercial installations that use solar trackers. Shneyder Solar, a manufacturer of solar panels, found that bifacial solar panels produced eleven percent higher solar output a tilted as well as a ground mounted solar array in China. A system with bifacial panels and solar tracker produced 27 percent more solar energy than traditional panels.
Since the panels absorb energy more from each side, bifacial panels could boost the energy output of massive solar farms. A solar panel mounted above ground can take in sunlight, and reflect it by solar cells backwards. The surface below can affect how much or little light is reflected back to panels. Reflected sunlight is more intense on surfaces with lighter colors, such as 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’re cheaper for larger solar installations that use reflective sunlight.
Bifacial panels can be employed in residential settings, however they are best suited to commercial or utility-scale solar power plants in the solar industry. Bifacial panels are able to shade free-standing structures like pergolas, and also generate surplus energy. In all cases where the panels are not directly visible, bifacial panels can also be used. Bifacial solar panel covers and awnings allow reflective sunlight to hit the backs of panels.
Bifacial panels are a good option for those who prefer a ground-mounted option over an on-roof one. A residential ground-mounted system works exactly the same way as commercial or utility applications. It is raised above the surface to allow sunlight to reach the panels‘ backsides.
Five Reasons Bifacial Panels are ideal for farms
- There is also more space
Ground mounts are ideal to ensure the highest the production capacity of bifacial panels. Ground mounts can be placed more away from roof mounts. To make the most of the area, rooftop solar panels are typically placed in a flush position next to one another. If the array is higher that the floor, like an awning, then there won’t be a lot of reflected light from the back side of the panel.
Businesses in rural areas and farms are able to use more land, which means you can disperse your bifacial panels in order to benefit from the full potential of reflectivity on the ground.
You also have the option of controlling how much light is reflecting. The panels will be exposed to more light if they have reflective surfaces like white rocks sand or another silver or white material.
Ground mounts can also be used in other ways. They could be used to cover your porch or yard or as carports. If you are interested in the bifacial-solar concept ensure you research the various options.
2. More Durable
Businesses and farmers who are involved in agriculture must be confident that their solar panels will last for a long time. This ensures that they will continue to make high-efficiency solar panels for many decades.
Bifacial panels are stronger than traditional one-sided panels which feature back sheets. They have glass faces on both sides. Tempered glass is the material used to make the glass. It is extremely tough and can withstand any force, including projectiles from hurricane force winds.
3. Longer Warranties
Shneyder Solar, a bifacial panel manufacturer, offers 30 years of warranty. This is five years longer than the warranty of 25 years that many manufacturers offer for one-sided panels.
Bifacial panels produce greater energy for each panel, and will last longer.
4. In Every Way the Trackers are better than Trackers in every way.
Trackers are a method of increasing solar output per panel. Trackers alter 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 cause issues. Trackers can be costly and can take longer to install.
While the cost of installing trackers using traditional panels is less than{ that of|| those with} Bifacial panels, they will yield similar quantities. There aren’t any moving parts so you don’t need to be concerned about them breaking.
5. Like regular solar cells.
As you’d imagine, bifacial panels are higher priced than regular ones in most cases. Shneyder Solar has a strong relationship to Canadian Solar, and we use them exclusively to obtain Bifacial solar panels at costs which are comparable to regular panels.
Shneyder Solar can offer ground-mounted solar panels that have Bifacial panels for a similar price to conventional panels to farms looking to increase their production.
For a similar cost, you can get higher production and better quality. This is the most you can get.
Shneyder Solar can often reduce the initial cost of their solar panels with grants or federal credit. In combination with the speedier production of bifacial panels can guarantee that you will be able to quickly recover the investment.
Tariff exemptions on Bifacial Panels
In the past few years tariffs on equipment and solar panels have had a huge impact on the industry. Trump put tariffs on non-domestically manufactured solar panels in the year 2018. The tariffs were aimed to encourage growth in the US’s solar manufacturing and production sector. This limited access to solar panels for cheaper prices.
These tariffs have been imposed by this administration Biden administration since taking its presidency. In fact, they have decided to extend them for four additional years starting 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 to access lower-cost panels.
Are bifacial panels worth the investment?
Although bifacial solar solar modules are a good option for utility and commercial solar builders, they don’t work well for residential rooftop projects. Bifacial solar panels are more expensive than the equipment that is required for residential rooftops, which means homeowners need to pay for them. But they provide greater effectiveness and savings. No matter how large your project, or where it is situated and what other considerations you have in mind when comparing quotes for solar panel installation is an excellent way to find a great price. Register your property on the Shneyder Solar solar pv market and start receiving quotes from professional solar installers who have been pre-screened and approved in your local area.
