Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar industry, a new product trend is emerging. Bifacial solar panels are solar panels that capture sunlight from both sides. They are an innovative solution for certain kinds of solar installations.
What are Bifacial Panels?
Panels with mono facial faces (traditional) are able to capture sunlight on one side. The light solar energy not captured is reflecting back. Bifacial solar panels don’t have this problem. Instead, they are equipped with solar cells on both ends. The panels are able to absorb light both from their front as well as back. This means that a bifacial panel is able to absorb light was reflected off of the ground or other materials.
Some residential applications like pergolas and ground-mounted systems, can benefit from solar panels that have bifacial faces. For the majority of property owners, however, rooftop installations with bifacial solar panels won’t be feasible. Instead, panels that are raised and tilted away from the mounting surface{ will|| can} permit light to reflect back onto the panels.
How does a Bifacial Solar Panels work?
The panels absorb light from both the front and back sides, allowing to diffuse light as much as is possible. Albedo light refers to the portion of light that bounces 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 travels in any direction. The bifacial panels can absorb direct sunrays and reflect radiation from nearby solar panels. It is also able to absorb diffused indirect radiation from air or clouds.
Bifacial solar panels come equipped with a glass-to glass structure. These panels offer longer-term durability as opposed to mono-face panels with back sheet glass that was previously offered. There are a variety of photovoltaic technologies that are thin-film currently. They include copper indium selenide (CIGS) and dye-sensitized photovoltaic cells. The majority of current thin-film solar technologies, such as CIGS or dye-sensitized cells, can be easily transformed into bifacial solar panels.
Bifacial solar panels come with front cover glass as well as a bifacial solar cell. Later, the unabsorbed photon in the front layer is absorbed slowly when it is released from the surrounding surface. This boosts the effectiveness of the bifacial solar cells. Glass-to glass structures bring many benefits for solar panels, such as reduced moisture corrosion, propagation of cracks and debonding. They also have a lower cell temperature and a slow rate of degradation. Bifacial solar panels are less flexible, yet they possess a high physical strength and fireproof rating.
Bifacial Solar Panels: The Advantages
- Unique ability to produce electricity directly from the sun.
- These panels can produce electricity through the reflection of light that is passing through them.
- Bifacial solar panels may be constructed of transparent or dual tempered back sheets, which is distinct from transparent back sheets.
- Degradation that could be caused by sunlight isn’t an issue for bifacial solar panels.
- The warranty on Bifacial solar panels lasts for almost 30 years. This is in contrast to the warranty of 25 years for conventional solar panels.
- The bifacial solar panel’s glass is designed to block water permeability and UV exposure.
- The modules are protected from corrosion by chemical due to their strong construction.
- The panels are constructed of solid glass that is impervious to cracking.
- The aluminum frames of the Bifacial solar panels don’t come included. They don’t require grounding. This saves time and material for installation costs.
Bifacial Solar Panels: The disadvantages
- Huge installation of bifacial panels cost.
- Double glass is one of the main reason for the high cost of solar panels with bifacial facets.
- Glass is a heavyweight.
- Bifacial solar panels are not utilized during night, cloudy days, or in storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels have one photovoltaic surface that can absorb light and transform it into renewable energy. Bifacial solar panels{ can|| are able to} take in sunlight on both sides and are smaller in size.
Bifacial panels work better than conventional panels due to the fact that they have more surface area that can absorb light. Bifacial panels that are vertically mounted can capture sunlight at sunset and sunrise. Panels mounted vertically can withstand weather conditions conditions such as sun and snow which may hinder their efficiency. The durability of bifacial solar panels are much 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 complicated than others and require additional work and equipment. They’re more efficient than vertically mounted panels, but homeowners may pay more because they require ground mounts. Additional requirements , such as the solar tracker system are also needed.
Bifacial Solar Panel Design
Bifacial panels are significantly different from the traditional polycrystalline and monocrystalline silicon panels. Although bifacial panels are typically comprised of monocrystalline cells, they are also polycrystalline options. Bifacial panels are distinguished by their thin profiles. Some bifacial designs require only minimal framing. The modules themselves are protected in a thin transparent layer. This could be an opaque back or a dual-glass sheet.
Bifacial solar panel mounting systems differ from conventional solutions. Bifacial solar panels require the least shaded surface both on their front and back surfaces to maximise solar energy capture. To minimize shading on the modules’ backsides, new rack designs can make use of more narrow support rails and junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panels are perfect for utility and commercial installations that utilize solar trackers. Shneyder Solar, a producer of solar panels discovered that solar panels with bifacial symmetry created 11 percent more solar energy in an inclined or ground-mounted system of solar in China. A system that has bifacial panels and solar tracker produced 27 % more solar power than one using traditional panels.
Since they absorb more energy from both sides, bifacial modules can boost the output of energy of massive solar farms. A solar panel mounted above the ground can take in sunlight, and reflect it through 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 projects with reflected sunlight.
Bifacial panels can be used in residential situations, but they are most suitable for commercial or utility-scale solar power projects in the solar industry. Bifacial panels can be utilized to shade structures that are freestanding such as pergolas and produce surplus energy. If the panels are not directly viewable, bifacial panel panels could also be employed. Bifacial solar panel canopies and awnings permit reflected sunlight to reach the backs of panels.
Bifacial panels are a good option for those who prefer a ground-mounted system over rooftop ones. Ground-mounted systems for residential use work exactly the same way as utility or commercial applications. It is elevated above ground in order for sunlight to reach the panels their back sides.
Five Reasons Bifacial Panels are ideal for farms
- There is also more space
Ground mounts are better for the best manufacturing of bifacial panel. Ground mounts can be set farther than roof mounts. To maximize the area, the rooftop solar panel is typically placed flush next to each other. In the event that the panel is higher then the surrounding ground for example, an awning, then there won’t be much reflected sunlight coming from the back of panels.
Rural businesses and farms have more land available, which allows for you to extend your bifacial panels in order to take full advantage of the ground reflection.
You can also control the amount of light reflect back. The panels will be more exposed to light if they are reflective like white rocks, sand or another white or silver material.
Ground mounts can also be used for other purposes. You could use them to cover your yard or porch, or as a carport. If you’re fascinated by the idea of bifacial-solar, make sure to investigate all options.
2. More Durable
Farmers and businesses that are involved in agriculture must be certain that their solar panels are durable for an extended time. It is a guarantee that they will continue to produce efficient solar panels for many decades.
Bifacial panels last longer than conventional one-sided panels that feature back sheets. They have glass faces each side. Tempered glass is the material used to make the glass. It is extremely durable and is able to withstand any force that is thrown at it, even projectiles from the force of hurricanes.
3. Longer Warranties
Shneyder Solar, a manufacturer of bifacial panels, offers the 30-year guarantee. It’s five years more than the 25-year warranty that many manufacturers offer for one-sided panels.
Your bifacial panels will produce higher energy output per unit, and will last longer.
4. In Every Way, Trackers are Better than Trackers
Trackers can be a means of increasing solar output per panel. Trackers can adjust the angle of solar panels in accordance with the position of the sun on the sky. This allows you to get more direct sunlight, and will last longer.
There are many moving parts in trackers. Like every appliance and mechanism they have more moving parts that could create problems. Trackers can be more expensive and can take longer to install.
Although the price of installing trackers that use traditional panels is less expensive than{ that of|| those with} Bifacial panels, they will still produce similar amounts. There aren’t any moving parts so you don’t need to be concerned about breaking them.
5. Similar to normal solar cells
Like you would imagine, bifacial 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 for sale at prices that are quite similar to standard panels.
Shneyder Solar can offer ground-mounted solar panels that have bifacial panels that are priced at the same price to conventional panels to farms seeking to boost their production.
For the same price, you get better production and higher quality. This is the most you can ask for.
Shneyder Solar can often lower their initial costs with grants or federal credit. Combining this with the faster production of bifacial solar panels will 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 has had a huge impact on the sector. Trump put tariffs on non-domestically produced solar panels in the year of 2018. These tariffs were designed to encourage growth in the US’s solar manufacturing and production sector. The tariffs impeded access to solar panels at the lower cost.
These tariffs have been maintained under the Biden administration since they took over the presidency. In fact, they have decided to extend them by 4 more years , beginning in 2022. But, they took an important decision by exempting bifacial panels of the tariffs. This decision is crucial for customers as it allows them access to cheaper panels.
Are bifacial panels worth the investment?
Although bifacial solar solar modules are an excellent alternative for commercial and utility solar builders, they do not perform well on rooftop residential projects. Bifacial solar panels cost more than the equipment that is required for residential rooftops, which means homeowners have to pay more for the panels. But they provide greater efficiency and lower costs. Whatever the size of your project is, the location it is situated and what other considerations you might have to consider when comparing quotes for a solar panel installation can be a great method to get a good bargain. Register your property on the Shneyder Solar solar pv market, and you will begin receiving quotes from professional solar installers who have been pre-screened and approved in your local area. You may also request a quote for bifacial panels simply by making a note in the profile.
