What are bifacial photovoltaic modules?
In principle, bifacial photovoltaic (PV) modules are simply PV modules whose full rear contact has been replaced with a fingerprint contact. This means that also the rear of the panel can be exposed to solar radiation and be used to produce power.
What is bifacial solar technology?
Therefore, we can say that bifacial technology is a relatively new development in solar panel design that presents both opportunities and challenges. Bifacial solar modules are modules that generate energy on both their front and rear sides, based on solar cells with two active sides.
What does bifaciality mean on solar panels?
First comes the term you might have spotted on the spec manual of these panels: ‘bifaciality’. It refers to their ability to generate electricity from both sides. This characteristic is quantified by the ‘bifaciality factor,’ which is the ratio of the efficiency of the rear side to that of the front side under the same irradiance conditions.
How do bifacial solar panels differ from traditional ones?
The majority of solar panels are monofacial. This means they have one photovoltaic side, which can absorb light from the sun and convert it into energy. Bifacial solar panels can absorb light on both sides and require less space.
Are bifacial PV modules better than monofacial solar panels?
Compared with monofacial PV modules, energy yields of around 10% higher (or even more) from bifacial modules in the field have been consistently reported by various parties [2,3]. Such increases in yield can considerably reduce the levelized cost of energy. Bifacial PV technology is not a new concept in the PV community.
How do bifacial solar panels work?
One round of operation ends for a monofacial panel after the incident light strikes the front side of the panel and is absorbed and converted into electricity. For a bifacial solar panel, in addition for front-side conversion, part of the direct light would pass through the panel and be reflected back to the rear side by the surface below.

High - Capacity Lithium - Ion Energy Storage Systems
Our high - capacity lithium - ion energy storage systems play a crucial role in optimizing solar energy usage. Utilizing state-of-the-art lithium-ion battery technology, they can store a significant amount of energy generated by solar panels during the day. This stored energy can then be used during peak demand periods or when sunlight is insufficient, such as at night or on cloudy days. With features like high energy density, fast charging, and long cycle life, these systems provide a reliable and efficient solution for energy storage, enabling you to achieve greater energy independence.
Smart Hybrid Inverters
Smart hybrid inverters are the key to a seamless and intelligent solar power system. They can intelligently manage the flow of electricity between solar panels, energy storage systems, and the electrical grid. These inverters not only convert the direct current (DC) from solar panels into alternating current (AC) for household or business use but also optimize the charging and discharging of energy storage systems. With built-in monitoring and communication features, you can remotely control and monitor your energy system, making it easy to adjust settings and track performance.
Portable Solar Power Stations
Portable solar power stations are designed for on-the-go power needs. They integrate solar panels, energy storage, and inverter functions into a single, lightweight unit. Ideal for outdoor enthusiasts, campers, and those in need of emergency backup power, these stations can charge various electronic devices like smartphones, laptops, and even small appliances. Their portability and ease of use make them a convenient choice for anyone who wants to access clean energy wherever there's sunlight, providing a reliable power source in remote locations or during power outages.
Distributed Photovoltaic Power Station Solutions
Our distributed photovoltaic power station solutions are tailored for various applications, from small communities to large industrial complexes. By distributing solar panel installations across multiple locations, we can make better use of available space and increase the overall energy generation capacity. These solutions are designed with high-performance components and integrated monitoring systems to ensure efficient operation, easy maintenance, and maximum energy yield. They also contribute to reducing the reliance on the main power grid and have a positive impact on the environment.
Micro Inverters
Micro inverters offer a unique advantage in solar power systems. Unlike traditional string inverters, each micro inverter is connected to a single solar panel, allowing for individual panel optimization. This means that even if one panel is shaded or has a lower performance due to some reason, it won't affect the overall output of the entire system. They are easy to install, highly efficient in converting DC to AC power, and provide better flexibility in system design, making them suitable for both residential and small commercial solar installations.
Roof - Integrated Photovoltaic Power Stations
Roof - integrated photovoltaic power stations combine the functionality of solar power generation with the aesthetics of building design. These stations are custom-designed to fit directly onto rooftops, replacing traditional roofing materials in part or in whole. They not only generate clean energy but also enhance the overall look of the building. With advanced installation techniques and durable materials, they can withstand the elements while providing a long-term and reliable source of electricity, making them an ideal choice for both new construction and retrofit projects.
