Advantages of Bifacial Solar Panels
Advantages of Bifacial Solar Panels
In the solar industry an exciting new trend in solar products is emerging. Bifacial solar panels are solar panels that take sunlight from both sides. They offer a unique solution to certain types of solar installation.
What are Bifacial Panels?
The mono-face panels (traditional) capture sunlight only on one side. Light solar energy that is not captured is reflect back. Bifacial solar panels do not suffer from this issue. Instead, they have 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 reflect off of the ground or other materials.
Certain residential installations like pergolas and ground-mounted systems, could benefit from bifacial solar panels. For the majority of homeowners however, rooftop installations with bifacial solar panels won’t be feasible. Instead, panels that are raised and angled away from a mounting surface{ will|| can} let light reflect back into the panels.
How does a Bifacial Solar Panels work?
The panels absorb light from the front and back sides and allow for the diffusion of light to be as large as is possible. Albedo light refers to the part of the sun’s light that is reflecting off of a surface. It can be as high as 30% efficiency, and is influenced by several variables like the reflectivity of the surface 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 is able to absorb direct radiation from the sun and reflect radiation from nearby solar panels. It also absorbs diffused indirect radiation from air particles or clouds.
Bifacial solar panels come fitted with a glass-to-glass construction. These panels offer longer-term durability as opposed to mono-face panels with back-to-glass sheet construction that was previously available. There are a variety of options for photovoltaics made of thin film in the present. This includes copper indium gallium selenide (CIGS) and dye-sensitized photovoltaic cells. The majority of current thin-film solar technologies including CIGS, or dye-sensitized cells, can be easily transformed into bifacial solar panels.
Bifacial solar panels come with the rear cover glass, and a bifacial solar cell. The photon that is not absorbed within the front cover glass is absorbed slowly as it recoils from the surrounding surface. This increases the effectiveness of the solar cells with bifacial symmetry. Glass-to-glass structures offer numerous advantages to solar panels, including reduced moisture corrosion, propagation of cracks, and debonding. They also have a lower cell temperature and a slow degrading rate. Bifacial solar panels tend to be less flexible, however they do have a high physical strength and fireproof 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 passes through them
- Bifacial solar panels may be constructed from transparent or dual-tempered back sheets, which differs from transparent back sheets.
- Degradation that could be caused by sunlight isn’t an issue with bifacial solar panels.
- The warranty for Bifacial solar panels lasts for almost 30 years. This is different from the 25-year warranty on conventional solar panels.
- The bifacial solar panel’s glass is designed to block the exposure to UV and also improves moisture permeability.
- They are safe 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 during installation costs.
Bifacial Solar Panels: The disadvantages
- A huge installation of bifacial panels cost.
- Double glass is one of the main reason for the cost of bifacial solar panels.
- Glass is very heavy.
- 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 sunlight and convert it into renewable energy. Bifacial solar panels{ can|| are able to} absorb sunlight from both sides and are smaller in size.
Bifacial panels perform better than conventional panels due to the fact that they have more surface for absorbing sunlight. 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 also higher than that of traditional panels.
Monofacial panels can still provide some benefits However, there are many other reasons why monofacial panels could be better than bifacial panels. Bifacial panels are more complicated than others and require extra work and equipment. They are much more effective than panels mounted vertically but homeowners could pay more because they require ground mounts. Additional requirements , such as sensors for solar energy are required.
Bifacial Solar Panel Design
Bifacial panels differ from conventional monocrystalline and polycrystalline silicon panels. Although bifacial panels are typically composed of monocrystalline cells, there are polycrystalline alternatives too. Bifacial panels stand out due to their thin profiles. A lot of bifacial designs need only limited framing. The modules themselves are protected in the form of a thin, transparent layer. This could be double-glass or a clear back sheet.
Bifacial solar panels mounting systems are different from traditional solutions. Bifacial solar panels need the least shaded areas both on their front and back surfaces in order to capture the maximum amount of solar energy. To lessen the shade on the modules’ backsides, 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 use 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 11 percent more solar energy the tilted as well as a ground mounted solar array in China. A system that has bifacial panels and a solar tracker generated an increase of 27 percent in solar energy than one using traditional panels.
Since that they take in more power from the two sides of their body, bifacial panels could boost the energy output of massive solar farms. A solar panel mounted above the ground will take in sunlight, and reflect it through solar cells that are oriented backwards. The surface beneath will affect how much or little light is reflected back to the panels. Reflected sunlight is more intense on surfaces with lighter colors like sand. This is more so 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 that have reflective sunlight.
Bifacial panels are able to be utilized in residential areas, but they’re best suited for commercial or utility-scale solar power plants in the solar industry. Bifacial panels can be utilized to shade free-standing structures such as pergolas and produce excess energy. In all cases where the panels aren’t visible, bifacial panels can also be used. Bifacial solar panel canopy and awnings allow for reflection of sunlight onto the backs of panels.
Bifacial panels can be a great option for those who prefer a ground-mounted system over an on-roof one. Ground-mounted systems for residential use work exactly the same way as utility or commercial installations. It is elevated above ground in order for sunlight to get to the panels their back sides.
Five Reasons Bifacial Panels are ideal for farms
- There is more space
Ground mounts are ideal for the best manufacturing of bifacial panel. Ground mounts are able to be placed farther than roof mounts. To maximize the space available, the rooftop solar panel is usually set flush with one another. When the solar arrays are higher than the ground, such as an awning, then there won’t be a lot of reflected sunlight coming from the back of panels.
Farms and other rural businesses have more land available, which allows for you to spread out your bifacial panel to benefit from the full potential of ground reflectivity.
You can also control how much light is reflect back. The panels will be more exposed to light if they have a reflective surface like white rocks, sand or some other silver or white substance.
Ground mounts can also be used for other purposes. They can be used to cover your patio or garden or even as a carport. If you’re interested in the bifacial-solar concept ensure you research all options.
2. More Durable
Farmers and businesses that are involved in agriculture must be confident that their solar panels can last for quite a period of time. This will ensure that they can continue to manufacture efficient solar panels for many decades.
Bifacial panels are more durable than conventional one-sided panels that feature back sheets. They feature glass facings on both sides. Tempered glass is used for the glass. It is extremely strong and can withstand any force that is thrown at it, even projectiles from hurricane force winds.
3. Longer Warranties
Shneyder Solar, a manufacturer of bifacial panels, offers 30 years of warranty. This is five years longer than the warranty of 25 years some manufacturers provide for single-sided panels.
Bifacial panels produce more energy per panel, and will last longer.
4. In Every Way the Trackers are better than Trackers in every way.
Trackers are a way to increase solar power per panel. Trackers adjust their angle on solar panel to match the position of the sun at the top of the sky. This lets you get more direct sunlight, and will last longer.
There are many moving parts in trackers. As with all appliances and mechanisms there are many moving parts that can cause problems. Trackers can be more expensive 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 will still produce similar amounts. There aren’t any moving parts and you do not have to worry about breaking them.
5. Comparable to regular solar cells
As you’d imagine, bifacial panels are more expensive than regular panels generally. Shneyder Solar has a strong relationship to Canadian Solar, and we make use of them exclusively to purchase bifacial solar panels at prices that are very comparable to regular panels.
Shneyder Solar can offer ground-mounted solar panels that have bifacial panels at a similar price to conventional panels for farms that want to increase their production.
For the same price, you get better production and higher quality. This is the highest quality you can get.
Shneyder Solar can often lower their initial costs by using a grant or federal credit. Combining this with the faster production of bifacial panels can guarantee that you will be able to quickly get back your investment.
Tariff exemptions on Bifacial Panels
Over the last several years tariffs on equipment as well as solar panels had huge impact on the sector. Trump imposed tariffs on non-domestically manufactured solar panels in the year 2018. These tariffs were designed to encourage growth in the US’s solar manufacturing and production sector. The tariffs impeded access to solar panels for a lower price.
The tariffs have been maintained under during the Biden administration since they took its presidency. In fact, they have decided to extend them for four more years , beginning in 2022. However, they made an important decision in disqualifying bifacial panels from tariffs. This is crucial to consumers since it allows them access to 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 are more expensive than the equipment that is required and homeowners will have to pay more for the panels. However, they offer greater efficiency and lower costs. No matter how large your project, or where it is located and what other considerations you may have in mind, getting multiple estimates for a solar panel installation can be a great method to get a good bargain.
