Advantages of Bifacial Solar Panels

Advantages of Bifacial Solar Panels

In the solar market, a new product trend is developing. Bifacial solar panels are solar panels that take sunlight from both sides. They provide a novel solution to certain types of solar installations.

What are Bifacial Panels?

Mono facial panels (traditional) capture sunlight only to one aspect. The light solar energy not captured is reflect back. Bifacial solar panels do not have this problem. Instead, they feature solar cells on both sides. The panels are able to absorb light both from in the back and front. This means that a bifacial panel can absorb light that has been bounced off the ground or other material.

Certain residential structures like pergolas and ground-mounted systems can benefit from bifacial solar panels. For the majority of homeowners, however, rooftop installations with solar panels that are bifacial won’t be practical. Instead panels that are raised and tilted away from the mounting surface allow light to reflect back onto the panels.

How does a Bifacial Solar Panels work?

The panels absorb light from both the back and front sides, allowing for diffused light as much as possible. Albedo light refers to the part of the light that bounces 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 refers to the scattered light that travels in any direction. The bifacial panel can absorb direct sunlight and reflected radiation from solar panels nearby. It can also absorb indirect diffused radiation from clouds or air particles.

Bifacial solar panels are fitted with a glass-to-glass construction. They provide longer-term reliability than the mono-face module with glass-to-back sheet structure that was previously available. There are a variety of 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, can easily be converted to bifacial solar panels.

Bifacial solar panels come with rear cover glass and the bifacial solar cell. In the future, the photon not absorbed inside the front layer will be absorbed slowly when it is released away from the surface. This improves the efficiency of the solar cells with bifacial symmetry. 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 lower rate of degradation. Bifacial solar panels tend to be less flexible, but they have an excellent mechanical strength and flameproof rating.

  • They are safe from chemical corrosion due to their high strength.
  • The panels are made from solid glass that is impervious to cracking.
  • The aluminum frames of the Bifacial solar panels don’t come included. They do not require grounding. This means that time and money are saved for installation costs.

Bifacial Solar Panels: The disadvantages

  • A huge installation of bifacial panels cost.
  • Double glass is the primary reason for the cost of bifacial solar panels.
  • Glass is heavyweight.
  • Bifacial solar panels cannot be utilized during evening, on cloudy days, or in storms.

Bifacial vs. Monofacial solar panels

Monofacial solar panels are made up of one photovoltaic surface that can absorb sunlight and convert it into renewable energy. Bifacial solar panels can take in sunlight on both sides, and are smaller in size.

Bifacial panels perform better than conventional panels due to the fact that they have more surface area for absorbing sunlight. Bifacial panels with a vertical layout can catch sunlight at sunrise and sunset. Panels that are vertically mounted are more resistant to weather such as sun and snow which may hinder their effectiveness. The longevity of solar panels with bifacial facets is much higher than conventional panels.

Monofacial panels may still have some advantages however there are numerous different reasons why monofacial panels may be more beneficial than bifacial. Bifacial panels can be more complex than other panels and require additional labor and equipment. They’re more efficient than vertically mounted panels, however homeowners might pay more because they require ground mounts. Additional requirements such as solar tracking systems are necessary.

Bifacial Solar Panel Design

Bifacial panels are quite different from conventional monocrystalline and polycrystalline silicon panels. Although bifacial panels are typically composed of monocrystalline cells, there are also polycrystalline options. Bifacial panels can be distinguished by their thin profiles. Many bifacial designs require limited framing. The modules themselves are protected by an extremely thin layer of transparent. It could be a dual-glass or clear back sheet.

Bifacial solar panels ‘ mounting systems are different from traditional solutions. Bifacial solar panels need the least shaded surface on their front and back surfaces in order to maximize solar energy capture. To reduce shading from the modules’ backsides, new racking solutions can use 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 make use of solar trackers. Nevada Solar Power Installers, a producer of solar panels discovered that solar panels with bifacial symmetry created 11 percent more solar energy in an inclined and ground-mounted solar system in China. A system that has bifacial panels and a solar tracker generated 27 percent more solar energy than one using traditional panels.

Since they absorb more energy from both sides, bifacial solar modules could boost the energy output of large-scale solar farms. A solar panel mounted above ground can be able to reflect light and then absorb the energy through solar cells in the opposite direction. The surface below will influence how much or little light is reflected back to panels. Reflected sunlight will be more intense on surfaces with lighter colors like sand, than those with darker surfaces, such as dirt or asphalt.

Can you use bifacial solar panels for residential installations?

Bifacial modules don’t suit rooftop solar installations. They are more cost-effective for larger solar projects with reflected sunlight.

Bifacial panels are able to be utilized in residential areas, but they’re best suited for utilities or commercial scale systems in the solar power industry. Bifacial panels are able to shade free-standing structures such as pergolas and generate surplus energy. If the panels are not directly viewable, bifacial panel panels could also be employed. Bifacial solar panel covers and awnings allow for reflection of sunlight onto the backs of panels.

Bifacial panels are a good alternative if you prefer a ground-mounted system to an on-roof one. A residential ground-mounted system works exactly the same way as utility or commercial applications. It is elevated above the ground in order for sunlight to get to the panels their back sides.

Five Reasons Bifacial Panels are ideal for farms

  1. There is also more space

Ground mounts are ideal for the best manufacturing of bifacial panel. Ground mounts can be placed more than roof mounts. To make the most of space, roof solar panels often placed in a flush position next to one another. If the array is higher that the floor, like an awning, then there will be less reflection sunlight coming from the back of the panel.

Rural businesses and farms have more land available which means you can extend your bifacial panels in order to maximize the benefits of ground reflectivity.

You also have the option of controlling the amount of light that is reflecting. The panels will be exposed to more light if they are reflective such as white rocks, sand or another white or silver material.

Ground mounts can also be utilized in different ways. They could be used as a cover for your patio or garden or as an autoport. If you are looking into the concept of bifacial solar ensure you research all options.

  1. More Durable

Businesses and farmers who are involved in agriculture need to be confident that their solar panels will last for a long period of time. This ensures that they will continue to manufacture high-efficiency solar panels for many decades.

Bifacial panels are stronger than conventional one-sided panels that include back sheets. They feature glass facings on both sides. Tempered glass is utilized for the glass. It is extremely tough and can withstand any force, including projectiles from the force of hurricanes.

  1. Longer Warranties

Nevada Solar Power Installers, a Bifacial panel maker, provides a 30-year warranty. This is five years more than the warranty of 25 years some manufacturers provide for single-sided panels.

Your bifacial panels will produce greater energy for each panel, and will last longer.

  1. In Every Way Trackers are superior than Trackers

Trackers are a method of increasing per-panel solar production. Trackers adjust angles of solar panels to align with the sun’s position on the sky. This allows you to get more direct sunlight, and will last longer.

Trackers have many moving parts. Similar to all appliances and mechanisms they have many moving parts that can create problems. Trackers can be more expensive and require more time to install.

Although the price of installing trackers that use traditional panels is less expensive than Bifacial panels, they still produce similar amounts. There are no moving parts and you do not need to be concerned about them breaking.

  1. Comparable to regular solar cells

Like you would think, bifacial solar panels are more expensive than regular ones in the majority of cases. Nevada Solar Power Installers has a close relationship with Canadian Solar, and we use them exclusively to obtain Bifacial solar panels at costs that are very comparable to regular panels.

Nevada Solar Power Installers can offer ground-mounted solar panels with bifacial panels at a similar price to conventional panels to farms seeking to boost their production.

For a similar price, you will get superior production and quality. This is the best you can ask for.

Nevada Solar Power Installers can often lower their initial costs through grants or a federal credit. This, when combined with the quicker production of bifacial panels will make sure that you are able to swiftly get back your investment.

Tariff exemptions on Bifacial Panels

In the last few years tariffs on equipment and solar panels had significant impact on the industry. Trump imposed tariffs on non-domestically produced solar panels in the year of 2018. The tariffs were aimed to boost expansion in the solar manufacturing and production sector. This restricted access to solar panels at the lower cost.

These tariffs have been maintained under the Biden administration since they took its presidency. In fact, they decided to extend them for 4 more years , beginning in 2022. But, they took an important choice by exempting bifacial panels of the tariffs. This is a crucial decision for consumers since it allows them to access lower-cost panels.

Are bifacial panels worth the investment?

Although bifacial solar solar modules are a good alternative for commercial and utility solar developers, they do not work well for residential rooftop projects. Bifacial solar panels are more costly than the equipment required for residential rooftops, which means homeowners have to pay more for the panels. But they provide greater efficiency and cost savings.
