Understanding Bifacial Solar Panels

bifacial solar panel trend

Bifacial solar panels diverge from traditional panels with their capability to absorb sunlight from both sides. They offer a unique design that caters to light penetration on the front and reflections from the surroundings on the rear side. By efficiently trapping light from all angles, they maximize the generation of solar energy.

A core component of bifacial panels is their dual-sided cells, intended to convert light into electricity on both sides. They are typically sandwiched between two layers of clear, protective material, providing a level of resilience comparable to or surpassing that of single-faced panels.

Additionally, these innovative sun catchers have diverse arrangements. While some are installed on flat rooftops or ground mounts, others are designed to track the sun’s path for increased exposure. Each installation style serves to capitalize on sunlight absorption, thus pushing energy generation to new heights.

It’s also fascinating to note that bifacial panels can vastly enhance energy production when paired with reflective surfaces. More light hitting the backside of a panel can stimulate increased power output, effectively optimizing the payoff of the investment in solar energy.

Lastly, to unlock the full potential of bifacial solar panels, careful consideration should be given to site selection and installation methods. Incorporating external factors like location, geographics, and seasonal light patterns can ensure the best possible energy yield.

Types of Bifacial Solar Panels: Heterojunction Cell and Passivated Emitter Rear Cell

Bifacial solar panels majorly come in two forms: Heterojunction Cell and Passivated Emitter Rear Cell, each having their distinctive elements and benefits.

The Heterojunction Cell, often abbreviated as HJT, combines crystalline and amorphous silicon, bringing the best of both worlds. The marriage of these two types of silicon results in panels that exhibit high efficiency and excellent performance, even when the sun’s rays are at a lower intensity. These panels are also known for their excellent heat resistance, rendering them ideal for hotter climates.

As for the Passivated Emitter Rear Cell, abbreviated as PERC, this type focuses more on boosting the efficiency per square meter. By implementing a reflective layer on the back of the cell, the scattered and residual light is pushed back towards the cell to be absorbed. This additional absorption of light is the reason why PERC panels may yield higher efficiency compared to other types of panels.

When choosing between Heterojunction and Passivated Emitter Rear Cell bifacial solar panels, consider factors such as climate, available space, and how optimized you want your panels to be for the available sunlight. With a bit of research and consideration, the right type of bifacial solar panel for your particular needs can be determined.

Known Differences Between Framed and Frameless Bifacial Solar Modules

Framed bifacial solar modules, as suggested by their name, come enclosed in a frame. This design provides additional structural integrity and eases installation procedures. Moreover, it offers added protection to the delicate edges of solar cells. On the flip side, the presence of a frame often obstructs a part of the rear-side sunlight exposure, somewhat compromising the overall efficiency.

Thread-like connectors—busbars—mark the face of a framed bifacial module. More busbars translate to reduced resistance and improved performance. However, the busbars cast a shadow on the module, impinging upon the sunlight capture.

On the contrary, frameless bifacial solar modules avoid the shadow effect cast by frames or busbars, enabling full sunlight exposure. These modules encapsulate solar cells between two glass layers, ensuring equivalent durability. These designs, while physically appealing, require special mounting gear, complicating the installation process.

Additionally, frameless modules offer aesthetic advantages with their sleek and modern look, blending seamlessly with most architectural trends.

Each module type comes with its own set of merits and considerations. Potential adopters should gauge these factors relative to their specific energy needs, aesthetic desires, and available budgets.

Common Applications of Bifacial Solar Panels: Residential, Commercial, Industrial

Harnessing their unique ability to generate electricity from both sides, bifacial solar panels demonstrate versatile applications in various settings.

In residential areas, bifacial solar panels have made strides, popular within households for their efficiency. They have found their place on rooftops, in gardens, or any open space. Taking advantage of their design, residential areas with reflective surfaces can maximise their energy output.

For commercial properties, these solar panels provide an opportunity to significantly reduce their electricity expenses. Large buildings, shopping malls, or office spaces often have extensive rooftop areas that can house bifacial panels. Carports are also an emerging trend, combining parking provisions with energy generation.

Industrial sectors are not left out. Large scale manufacturing and processing plants can benefit from the higher power output of bifacial solar panels. Deploying them on a larger scale across unused lands within industrial complexes has the potential to provide significant returns on investment.

In terms of installation, bifacial panels require special mounting for optimal performance. The panels need to be slightly elevated to ensure the underside can capture reflected sunlight. It’s also necessary to consider the orientation, tilt, and spacing between the panels for maximising power generation. The installation can be a DIY project for some, but it’s advised to use professional services for optimal system design and installation.

To safeguard the environment and save on energy costs, bifacial solar panel use is an emerging trend, making it a suitable solution across residential, commercial, and industrial applications.
