Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar market, a new product trend is emerging. Solar panels with Bifacials capture sunlight from both their rear and front. They provide a novel solution to certain kinds of solar installations.
What are Bifacial Panels?
Panels with mono facial faces (traditional) take in sunlight only to one aspect. 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 ends. The panels can absorb light from both the front and back. This implies that a bifacial wall can absorb light that was reflected off of the ground or other materials.
Certain residential structures like pergolas or ground-mounted systems, could benefit from bifacial solar panels. For the majority of property owners however, rooftop installations with bifacial solar panels won’t be practical. Instead panels that are elevated and tilted away from the 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, allowing for diffused light as much as it is possible. Albedo light refers the portion of 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 surfaces on ground, height above ground and tilt angle. Diffused light is scattered light that travels in any direction. The bifacial panels can absorb direct radiation from the sun and reflect radiation from solar panels nearby. It also absorbs diffused indirect radiation from air or clouds.
Bifacial solar panels come equipped with a glass-to-glass structure. They offer greater durability than the mono-face module with back sheet glass which was previously available. There are a variety of options for photovoltaics made of thin film currently. This includes copper indium gallium selenide (CIGS) and dye-sensitized photovoltaic cells. Many current thin-film solar technology like CIGS and dye-sensitized cells, can be easily converted to bifacial solar panels.
Bifacial solar panels are made up of rear cover glass and the bifacial solar cell. Later, the unabsorbed photon in the front layer will be absorbed slowly when it is released from its surrounding surface. This increases the effectiveness of the Bifacial solar cells. Glass-to-glass structures provide a variety of advantages for solar panels, such as decreased moisture corrosion, the development of cracks, and debonding. They have a reduced cell temperature and a slow decay rate. Bifacial solar panels tend to be less flexible, yet they possess a high physical strength and fireproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to produce electricity directly from sunlight.
- These panels are able to generate electricity through the reflection of light passing through them.
- Bifacial solar panels can be made from either transparent or dual tempered back sheets. This is different from the opaque back sheets.
- Degradation that could be caused by sunlight isn’t a concern with solar panels with bifacial faces.
- The warranty on Bifacial solar panels lasts for almost 30 years. This is in contrast to the warranty of 25 years for the traditional panels.
- The bifacial solar panel’s glass helps to prevent the exposure to UV and also improves moisture permeability.
- The modules are shielded against chemical corrosion because of their high strength.
- The panels are constructed of solid glass that is impervious to cracking.
- The aluminum frames of the bifacial solar panels are not included. They do not require grounding. This can save time and materials in the process of installation.
Bifacial Solar Panels: The disadvantages
- Huge installation of bifacial panels cost.
- Double glass is one of the main factor in the high price of bifacial solar panels.
- Glass is a heavyweight.
- Bifacial solar panels cannot be used during the night, cloudy days, or storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels have one photovoltaic side that absorbs light and transform it into renewable energy. Bifacial solar panels{ can|| are able to} absorb sunlight from both sides and take up less space.
Bifacial panels work better than conventional panels due to the fact that they have more surface to absorb sunlight. Vertically arranged bifacial panels can capture sunlight at sunrise and sunset. Panels that are mounted vertically have a greater resistance to the elements such as sun and snow which can reduce their efficiency. The durability of solar panels with bifacial facets is much higher than conventional panels.
Monofacial panels could still offer some advantages however there are numerous different reasons why monofacial panels may be better than bifacial panels. Bifacial panels may be more complicated than other types and require extra work and equipment. They’re better than horizontally mounted ones however homeowners might pay more because they require ground mounts. Additional requirements , such as the solar tracker system are also necessary.
Bifacial Solar Panel Design
Bifacial panels differ from conventional monocrystalline and polycrystalline silicon panels. Although bifacial panels are typically made of monocrystalline cells there are also polycrystalline options. Bifacial panels stand out due to their slim profile. Many bifacial designs require minimal framing. The modules themselves are protected in a thin transparent layer. This could be a dual-glass or clear back sheet.
Bifacial solar panels mounting systems differ from conventional solutions. Bifacial solar panels need the least shaded area on their front and back surfaces to maximize solar energy capture. To reduce shading from the modules’ backsides 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 utilize solar trackers. Shneyder Solar, a producer of solar panels discovered that bifacial solar panels produced eleven percent higher solar output when used in a tilted as well as a ground mounted solar array in China. A system with bifacial panels and solar tracker produces an increase of 27 percent in solar power than one using traditional panels.
Because they absorb more energy from both sides, bifacial solar modules can increase the energy output of massive solar farms. A solar panel that is placed above the ground will take in sunlight, and reflect it through solar cells in the opposite direction. The surface below can affect the amount or how much light is reflected back to the panels. Reflected sunlight is brighter on lighter surfaces 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’re cheaper for larger solar projects with reflection of sunlight.
Bifacial panels can be used in residential situations, but they are most suitable for utilities or commercial scale plants in the solar sector. Bifacial panels can be utilized to shade structures that are freestanding such as pergolas and produce excess energy. In any case where the panels aren’t directly visible, bifacial panels may be utilized. Bifacial solar panel canopies and awnings permit reflective sunlight to hit the panels’ backs.
Bifacial panels can be a great alternative if you prefer a ground-mounted system to a rooftop one. A ground-mounted residential system functions in the same way as commercial or utility applications. It is elevated above the ground in order for sunlight to penetrate 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 can be set more apart than roof mounts. To maximize the area, roof solar panels typically placed flush next to one another. If the array is higher then the surrounding ground like an awning, there won’t be a lot of reflected light from the back side of the panels.
Farms and other rural businesses have more land available which means you can extend your bifacial panels to benefit from the full potential of the ground reflection.
You also have the option of controlling how much light is reflected. Your panels will be more exposed to light in the event that they have a reflective surface 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 porch or yard or as carports. If you are looking into the concept of bifacial solar, make sure to investigate the various options.
2. More Durable
Farmers and businesses that are involved in agriculture must be certain that their solar panels will last for a long period of time. This will ensure that they can continue to produce high-efficiency solar panels over the course of several decades.
Bifacial panels last longer than traditional one-sided panels which have back sheets. They feature glass facings on both sides. Tempered glass is used for the glass. It is extremely durable and can withstand any force, including projectiles from the force of hurricanes.
3. Longer Warranties
Shneyder Solar, a manufacturer of bifacial panels, offers a 30-year warranty. It’s five years more than the warranty of 25 years that some manufacturers provide for single-sided panels.
Your bifacial panels will produce more energy per panel, and will last longer.
4. In Every Way, Trackers are Better than Trackers
Trackers are a way of increasing per-panel solar production. Trackers adjust angles of solar panels to align with the position of the sun at the top of the sky. This allows you to get more direct sunlight, and will last longer.
Trackers are made up of many moving parts. As with any appliance or mechanism, there are more moving parts that could cause problems. Trackers are more costly and take longer to install.
Although the price of installing trackers using traditional panels is less expensive than{ that of|| those with} Bifacial panels, they will still produce similar amounts. There aren’t any moving parts and you do not have to be worried about breaking them.
5. Like regular solar cells.
As you might think, bifacial solar panels are more expensive than regular panels generally. Shneyder Solar has a strong relationship to Canadian Solar, and we utilize them exclusively for bifacial solar panels at prices that are very similar to standard panels.
Shneyder Solar can offer solar panels for ground mounted with bifacial panels at a similar cost to conventional panels for farms seeking to boost their production.
For a similar cost, you can get higher production and better quality. This is the highest quality that you can ask for.
Shneyder Solar can often reduce their upfront costs with grants or federal credit. This, when combined with the quicker production of bifacial panels will guarantee that you will be able to quickly make a profit on the investment.
Tariff exemptions on Bifacial Panels
In the past few years tariffs on equipment and solar panels had significant impact on the industry. Trump imposed tariffs on non-domestically manufactured solar panels in the year 2018. The tariffs were aimed to boost expansion in the solar manufacturing and production sector. This restricted access to solar panels at cheaper prices.
These tariffs have been imposed through the Biden administration since they took over the presidency. In fact, they decided to extend them by 4 additional years starting in 2022. However, they made an important choice by exempting bifacial panels from the tariffs. This decision is crucial for consumers as it allows them to access cheaper panels.
Are bifacial panels worth the investment?
Although bifacial solar modules can be a great option for utility and commercial solar companies, they won’t make sense for rooftop residential projects. Bifacial solar panels cost more than the equipment required, so homeowners will still be required to shell out more for them. They do however offer better effectiveness and savings. Whatever the size of your project, or where it is situated or any other requirements you have in mind when comparing quotes for a solar panel installation is an excellent option to secure a fantastic price. Sign up your property to the Shneyder Solar solar pv market, and you will begin receiving quotes from qualified solar installers that have been pre-screened in your local area. You can also request a quotation for bifacial panels by simply adding a note to the profile.
