Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar sector there is a new trend of solar panels that is developing. Bifacial solar panels are solar panels that take sunlight from both their front and rear. They offer a unique solution to certain kinds of solar installations.
What are Bifacial Panels?
Panels with mono facial faces (traditional) are able to capture sunlight to one aspect. The light solar energy not captured is reflected back. Bifacial solar panels don’t suffer from this issue. Instead, they are equipped with solar cells at both ends. The panels are able to absorb light both from the front and back. This means that a bifacial panel is able to absorb light was reflect off of the ground or another materials.
Certain residential structures like pergolas or ground-mounted systems, can benefit from bifacial solar panels. For the majority of property owners however, rooftop installations using 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 onto the panels.
How does a Bifacial Solar Panels work?
The panels reflect light from the sides facing forward and back and allow for diffused light as much as possible. Albedo light refers to the part of the sunlight that is reflected off of a surface. It can be as high as 30% efficiency, and is influenced by several aspects like the reflectivity of ground surfaces in relation to height above the ground, as well as tilt angle. Diffused light refers to the scattered light that travels in any direction. The bifacial panel is able to absorb direct sunrays as well as reflected radiation from solar panels nearby. It is also able to absorb diffused indirect radiation from air particles or clouds.
Bifacial solar panels are fitted with a glass-to-glass construction. They offer greater durability over the mono-face modules with a glass-to-back sheet structure that was previously offered. There are many thin-film photovoltaic technology options available in the present. They include copper indium selenide (CIGS) and dye-sensitized photovoltaic cells. A lot of the current technology for solar thin-film like CIGS and dye-sensitized cells, can be easily transformed into bifacial solar panel.
Bifacial solar panels have rear cover glass and bifacial solar cell. Later, the unabsorbed photon inside the front layer will be slowly absorbed when it is released away from the surface. This boosts the effectiveness of bifacial solar cells. Glass-to glass structures bring many benefits for solar panels, such as less moisture corrosion, the propagation of cracks, and debonding. They have a reduced cell temperature, and a lower degrading rate. Bifacial solar panels are more flexible, however they do have high mechanical strength and a flameproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to produce electricity directly from sunlight.
- These panels are able to generate electricity by absorbing the light that is passing through them
- Bifacial solar panels are constructed of transparent or dual-tempered back sheets. This is distinct from opaque back sheets.
- Potentially induced degradation is not a concern with solar panels with bifacial faces.
- The warranty on solar panels with bifacial design is nearly 30 years. This is in contrast to the warranty of 25 years on conventional solar panels.
- The bifacial solar panels’ glass can help to reduce UV exposure and moisture permeability.
- The modules are protected from corrosion by chemical due to their strong construction.
- The panels are made of strong glass that is resistant to cracking.
- The aluminum frames of Bifacial solar panels don’t come included. They do not require grounding. This means that time and money are saved in the process of installation.
Bifacial Solar Panels: The disadvantages
- Huge installation of bifacial panels cost.
- Double glass is one of the main reason for the cost of solar panels with bifacial facets.
- Glass is a heavyweight.
- Bifacial solar panels cannot be employed during the evening, on cloudy days, or during storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels have one photovoltaic face that can absorb sunlight and convert it to renewable energy. Bifacial solar panels{ can|| are able to} absorb sunlight from both sides and require less space.
Bifacial panels perform better than traditional panels because they have more surface area for absorbing sunlight. Bifacial panels with a vertical layout can catch sunlight at sunset and sunrise. Panels that are mounted vertically are more resistant to weather, such as sun and snow which could block some of their efficiency. The longevity of bifacial solar panels are significantly higher than traditional panels.
Monofacial panels may still have certain advantages, but there are many other reasons why monofacial panels could be better than bifacial panels. Bifacial panels can be more complex than other panels 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. Other requirements like sensors for solar energy are also needed.
Bifacial Solar Panel Design
Bifacial panels differ from the traditional polycrystalline and monocrystalline silicon panels. While bifacial panels are generally made of monocrystalline cells there are polycrystalline alternatives too. Bifacial panels stand out due to their thin profiles. Some bifacial designs require only limited framing. The modules are protected with an extremely thin layer of transparent. This can be either a dual-glass or clear back sheet.
Bifacial solar panel mounting systems are different from traditional solutions. Bifacial solar panels require the least shaded area on their front and back surfaces to maximize solar energy capture. To lessen the shade on the back of the module, new rack solutions are able to use smaller support rails as well as junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panel usage is perfect for utility and commercial installations that use solar trackers. Shneyder Solar, a producer of solar panels discovered that solar panels with bifacial symmetry produced eleven percent higher solar output in a tilted or ground-mounted system of solar in China. A system with bifacial panels and solar tracker produced 27 % more solar energy than traditional panels.
Since that they take in more power from the two sides of their body, bifacial panels can increase the energy output of large-scale solar farms. A solar panel that is placed above ground can reflect sunlight and absorb it by solar cells that are oriented backwards. The surface beneath will affect the amount or how much light is reflected back to panels. Reflected sunlight will be more intense on lighter surfaces, 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 more affordable for larger solar projects with reflection of sunlight.
Bifacial panels are able to be utilized in residential settings, however they are most suitable for utilities or commercial scale systems in the solar industry. Bifacial panels can be used to shade structures that are freestanding like pergolas, and also generate extra energy. In any case where the panels aren’t directly viewable, bifacial panel panels could also be used. Bifacial solar panel covers and awnings permit reflected sunlight to reach the backs of panels.
Bifacial panels can be a great option for those who prefer a ground-mounted option over rooftop ones. Ground-mounted systems for residential use work exactly the same way as utility or commercial installations. It is elevated above the ground in order for sunlight to reach the panels the backsides.
Five Reasons Bifacial Panels are ideal for farms
- There is also more space
Ground mounts are more suitable to ensure the highest the production capacity of bifacial panels. Ground mounts are able to be placed farther apart than roof mounts. To make the most of the area the rooftop solar panel is often set flush with one another. When the solar arrays are larger than the ground, like an awning, there will be less reflection sunlight coming from the back of panels.
Rural businesses and farms are able to use more land, which allows for you to spread out your bifacial panels in order to benefit from the full potential of reflectivity on the ground.
You also have the option of controlling the amount of light that is reflect back. Your panels will be more exposed to light if they have a reflective surface like white rocks, sand, or any other silver or white material.
Ground mounts may also be used in other ways. They could be used to cover your porch or yard or even as an autoport. If you’re fascinated by the idea of bifacial-solar be sure to research the various options.
2. More Durable
Farmers and businesses that are involved in agriculture must be confident that the solar panels they install will last for a long period of time. This will ensure that they can continue to make efficient solar panels for several decades.
Bifacial panels are stronger than traditional one-sided panels which have back sheets. They have glass faces each side. Tempered glass is utilized for the glass. It is extremely strong and can withstand any force that is thrown at it, even projectiles from the force of hurricanes.
3. Longer Warranties
Shneyder Solar, a Bifacial panel maker, provides 30 years of warranty. This is five years more than the 25-year warranty that many manufacturers offer for one-sided panels.
The bifacial panels you have will generate greater energy for each panel, and will last longer.
4. In Every Way the Trackers are better Than Trackers
Trackers are a way of increasing solar output per panel. Trackers adjust their angle on solar panel to align with the sun’s position at the top of the sky. This lets you get more direct sunlight, and lasts longer.
Trackers are made up of many moving parts. As with all appliances and mechanisms they have many moving parts that can cause issues. Trackers are more costly and take longer to set up.
While the cost of installing trackers using traditional panels is lower than{ that of|| those with} Bifacial panels, they still produce similar amounts. There are no moving parts so you don’t need to be concerned about breaking them.
5. Similar to normal solar cells
Like you would think, bifacial solar panels are more expensive than regular panels generally. Shneyder Solar has a strong relationship to Canadian Solar, and we use them exclusively to obtain Bifacial solar panels at costs that are very similar to standard panels.
Shneyder Solar can offer ground-mounted solar panels that have Bifacial panels for a similar price to conventional panels to farms that want to increase their production.
For the same cost, you can get higher production and quality. This is the highest quality you can get.
Shneyder Solar can often reduce their upfront 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 recover the investment.
Tariff exemptions on Bifacial Panels
Over the last several years tariffs on equipment as well as solar panels have had a huge impact on the sector. Trump put tariffs on non-domestically manufactured solar panels in the year 2018. These tariffs were designed to boost expansion in the solar manufacturing and production sector. This restricted access to solar panels for the lower cost.
These tariffs have been imposed through during the Biden administration since it took its presidency. They even decided to extend them for 4 more years in 2022. But, they took an important choice by exempting bifacial panels of the tariffs. This is crucial to consumers as they can access cheaper panels.
Are bifacial panels worth the investment?
While bifacial solar panels are a good alternative for commercial and utility solar companies, they do not perform well on rooftop residential projects. Bifacial solar panels cost more than the equipment needed and homeowners will have to pay more for the panels. They do however offer better effectiveness and savings. No matter how large your project is, the location it is located or any other requirements you might have to consider when comparing quotes for solar panel installations is a good method to get a good bargain. Register your property on the Shneyder Solar solar pv market and begin receiving quotes from qualified, pre-screened solar installers in your local area. You can also request a quote for bifacial panels simply by adding a note to the profile.
