Advantages of Bifacial Solar Panels
In the solar industry there is a new trend of solar panels that is emerging. Bifacial solar panels are solar panels that capture sunlight from both sides. They offer a unique solution for certain kinds of solar installation.
What are Bifacial Panels?
Mono facial panels (traditional) take in sunlight only to one aspect. Solar energy that is not captured is reflect back. Bifacial solar panels don’t have this problem. Instead, they feature solar cells on both ends. The panels can absorb light from both their front as well as back. This is why a bifacial panel is able to absorb light was reflect off of the ground or other material.
Certain residential structures, such as pergolas or ground-mounted systems can benefit from Bifacial solar panels. For most property owners however, rooftop installations using Bifacial solar panels aren’t feasible. Instead, panels that are raised and set away from a mounting surface{ will|| can} allow light to reflect back to the panels.
How does a Bifacial Solar Panels work?
The panels absorb light from the back and front sides and allow for diffused light as much as possible. The term “albedo” refers to the part of the light that bounces off of a surface. It is able to reach 30 percent efficiency, and is influenced by several variables like the reflectivity of ground surfaces in relation to height above the ground, as well as tilt angle. Diffused light is the scattered light that can travel in any direction. The bifacial panel is able to absorb direct sunrays and reflect radiation from nearby solar panels. It can also absorb indirect diffused radiation from air or clouds.
Bifacial solar panels are 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 numerous thin-film photovoltaic technology options available currently. 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, are easily converted to bifacial solar panels.
Bifacial solar panels are made up of the rear cover glass, and a bifacial solar cell. Later, the unabsorbed photon in the front layer is absorbed slowly when it is released from its surrounding surface. This boosts the effectiveness of the bifacial solar cells. Glass-to-glass structures offer numerous advantages to solar panels. These include reduced moisture corrosion, propagation of cracks and debonding. They have a reduced cell temperature, and a lower degrading rate. Bifacial solar panels are more flexible, but they 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 passes through them
- Bifacial solar panels may be made from either transparent or dual-tempered back sheets. This is different from the transparent back sheets.
- The possibility of degradation caused by the sun isn’t an issue with solar panels with bifacial faces.
- The warranty for bifacial solar panels is almost 30 years. This is different from the warranty of 25 years on conventional solar panels.
- The bifacial solar panels’ glass helps to prevent UV exposure and moisture permeability.
- The modules are protected from corrosion by chemical due to their strength.
- The panels are made of solid glass that is impervious to cracking.
- The aluminum frames of bifacial solar panels are not 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 bifacial solar panels.
- Glass is very heavy.
- Bifacial solar panels cannot be employed during the dark, cloudy days or in storms.
Bifacial vs. Monofacial solar panels
Monofacial solar panels have one photovoltaic surface that can absorb the sunlight, and then convert it into renewable energy. Bifacial solar panels{ can|| are able to} take in sunlight on both sides and take up less space.
Bifacial panels are more efficient than conventional panels due to the fact that they have more surface to absorb sunlight. Vertically arranged bifacial panels are able to capture sunlight during sunset and sunrise. Panels mounted vertically are more resistant to weather conditions such as sun and snow which can reduce their effectiveness. The longevity of bifacial solar panels is also higher than that of conventional panels.
Monofacial panels can still provide some benefits however there are numerous other reasons monofacial panels might be more beneficial than bifacial. Bifacial panels are more complicated than others and require more effort and the use of equipment. They’re much more effective than panels mounted vertically, however homeowners might pay more because they require ground mounts. Other requirements like the solar tracker system are needed.
Bifacial Solar Panel Design
Bifacial panels differ from the traditional polycrystalline and monocrystalline silicon panels. Although bifacial panels are typically made of monocrystalline cells there are polycrystalline alternatives too. Bifacial panels can be distinguished by their thin profile. Many bifacial designs require minimal framing. The modules themselves are protected by a thin transparent layer. It could be a dual-glass or clear back sheet.
Bifacial solar panel mounting systems differ from conventional solutions. Bifacial solar panels need the least shaded area both on their front and back surfaces to maximise solar energy capture. To minimize shading on the modules’ backsides, new racking solutions can use narrower support rails and junction boxes.
Bifacial Solar Panels for Commercial and utility-scale Applications
Bifacial solar panel usage is ideal for utility and commercial installations that utilize solar trackers. Shneyder Solar, a producer of solar panels discovered that solar panels with bifacial symmetry generated an increase of 11 percent in solar power in an inclined or ground-mounted system of solar 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 panels could boost the energy output of large-scale solar farms. Solar panels that are placed above ground can take in sunlight, and reflect it by solar cells backwards. The surface below can affect the amount or how much light is reflected back to panels. Reflected sunlight will be 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 are able to be utilized in residential situations, but they are most suitable for utilities or commercial scale plants in the solar sector. Bifacial panels can be used to shade structures that are freestanding like pergolas, and also generate extra energy. If the panels aren’t visible, bifacial panels can be utilized. Bifacial solar panel covers and awnings allow for reflection of sunlight onto the panels’ backs.
Bifacial panels can be a great option if you prefer a ground-mounted option over an on-roof one. Ground-mounted systems for residential use work in the same way as utility or commercial installations. It is elevated above surface to allow sunlight to reach the panels‘ backsides.
Five Reasons Bifacial Panels are ideal for farms
- There is more space
Ground mounts are better to ensure the highest manufacturing of bifacial panel. Ground mounts can be set further apart than roof mounts. To make the most of the space available, the rooftop solar panel is usually placed in a flush position next to one another. If the array is taller that the floor, for example, an awning, then there won’t be much reflected light from the back side of panels.
Businesses in rural areas and farms have more land available that allows you to extend your bifacial panels in order to maximize the benefits of reflectivity on the ground.
You can also regulate the amount of light reflected. The panels will be exposed to more light when they have reflective surfaces such as white rocks, sand, or any other silver or white material.
Ground mounts can be used for other purposes. They can be used as a cover for your yard or porch or as carports. If you are 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 the solar panels they install can last for quite a time. This will ensure that they can continue to make high-efficiency solar panels over the course of many years.
Bifacial panels are stronger than standard one-sided panels that feature back sheets. They have glass faces on both sides. Tempered glass is used for the glass. It is extremely tough and is able to withstand any force that is thrown at it, even projectiles from hurricane force winds.
3. Longer Warranties
Shneyder Solar, a bifacial panel manufacturer, offers the 30-year guarantee. This is five years longer than the warranty of 25 years that many manufacturers offer for one-sided panels.
Your bifacial panels will produce greater energy for each panel and last for longer.
4. In Every Way, 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 in accordance with the sun’s position on the sky. This allows you to get more direct sunlight, and lasts longer.
Trackers are made up of many moving parts. Similar to all appliances and mechanisms there are more moving parts that could create problems. Trackers can be costly and require more time to set up.
Although the price of installing trackers with traditional panels is less than{ that of|| those with} Bifacial panels yield similar quantities. There are no moving parts so you don’t have to worry about them breaking.
5. Comparable to regular solar cells
As you’d imagine, bifacial panels are more expensive than regular ones generally. Shneyder Solar has a solid relationship with Canadian Solar, and we make use of them exclusively to purchase bifacial solar panels at prices that are quite comparable to regular panels.
Shneyder Solar can offer ground-mounted solar panels that have bifacial panels that are priced at the same 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 ask for.
Shneyder Solar can often reduce their upfront costs through grants or a federal credit. This, when combined with the quicker production of bifacial panels will ensure that you can quickly make a profit on your investment.
Tariff exemptions on Bifacial Panels
In the last few years, tariffs on equipment and solar panels had huge impact on the sector. Trump has imposed tariffs on foreign produced solar panels in 2018. These tariffs were designed to encourage expansion in the solar production and manufacturing. This limited the availability of solar panels at a lower price.
These tariffs have been imposed through the Biden administration since taking to the office. In fact, they decided to extend them for 4 additional years starting in 2022. But, they took an important decision by exempting bifacial panels of the tariffs. This is a crucial decision for consumers as it allows them access to cheaper panels.
Are bifacial panels worth the investment?
Although bifacial solar modules can be a great alternative for commercial and utility solar builders, they won’t perform well on rooftop residential projects. Bifacial solar panels are more expensive than the equipment that is required, so homeowners will still need to pay for the panels. However, they offer greater efficiency and lower costs. No matter how large your project is, where it is situated and what other considerations you might have to consider, getting multiple quotes for solar panel installations is a good way to find a great bargain. Register your property on the Shneyder Solar solar pv market and begin receiving quotes from professional solar installers that have been pre-screened within your area. You can also request a quotation for bifacial solar panels by noting it in your profile.
