Types of PV Modules Made by GREW - Bifacial and Mono Perc

Photovoltaic (PV) modules are the building blocks of solar power systems, and as technology
advances, so do the types of PV modules available in the market. GREW, a renowned
manufacturer in the solar industry, has been at the forefront of innovation, producing state-of-the-art
bifacial and mono PERC modules that have transformed solar installations and solar asset management.
In this blog post, we will explore these two types of PV modules made by GREW and delve into their
unique features and benefits. 



Bifacial PV Modules: A New Horizon in Solar Power 

Bifacial PV modules are designed to capture sunlight from both sides, front and rear, effectively
increasing energy generation compared to traditional single-sided panels. This innovative design
is made possible by using transparent back sheets or dual glass, allowing light to be absorbed
from the backside when it reflects off the ground or other surfaces. The increased light absorption
leads to higher energy yields, making bifacial modules a popular choice for solar O&M (operations
and maintenance) professionals looking to maximize the performance of solar installations. 
The key advantage of bifacial modules lies in their ability to harness albedo, which is the reflected light from the Earth's surface. Surfaces like white gravel, snow, or even green grass can reflect significant amounts of light, enhancing the overall efficiency of bifacial panels. This feature is particularly beneficial in regions with high levels of diffuse light or where ground reflection is naturally higher. 

Mono PERC PV Modules: Elevating Efficiency and Performance 

Mono PERC (Monocrystalline Passivated Emitter and Rear Cell) modules represent a leap
forward in solar panel technology. PERC technology enhances the efficiency of standard
monocrystalline solar cells by adding a passivation layer on the rear side of the cell. This layer
serves multiple functions: it reflects light back into the cell for a second chance at absorption,
reduces electron recombination to enhance electrical flow, and allows for more wavelengths
of light to be captured. 
GREW's mono PERC modules are known for their high efficiency, which translates to more power output per square meter. For homeowners and businesses with limited roof space, these modules are an excellent choice as they can generate more solar power in a smaller area. Solar installation professionals often prefer mono PERC modules for their superior performance in low-light conditions, such as early morning or late afternoon, and their lower degradation rates over time. 

Solar Asset Management with Advanced PV Modules 

Effective solar asset management is crucial for maintaining the long-term performance and
reliability of solar power systems. GREW's bifacial and mono PERC modules offer distinct
advantages in this regard. Bifacial modules' ability to generate additional energy can lead
to better financial returns on solar investments. This is particularly important for large-scale
solar projects where every increment in efficiency can result in significant gains in energy
production and revenue. 

Mono PERC modules, with their high-efficiency ratings, contribute to reduced operational costs and increased energy yield throughout the lifespan of the solar power system. Their durability and resistance to environmental factors make them a robust choice for solar asset managers who aim to minimize downtime and maintenance expenses. 

The Future of Solar O&M with Bifacial and Mono PERC Modules 

As the solar industry continues to evolve, the importance of advanced O&M practices cannot
be overstated. Bifacial and mono PERC modules from GREW require specialized knowledge
and handling to ensure they perform at their peak potential. Solar O&M teams are adapting
to these new technologies by employing sophisticated monitoring systems and predictive
maintenance strategies. These practices help in identifying potential issues before they escalate,
ensuring the longevity and profitability of solar power installations. 

In conclusion, GREW's bifacial and mono PERC PV modules represent the cutting edge of solar technology. By embracing these types of PV modules, solar power stakeholders - from installers to asset managers—can reap the benefits of higher energy yields, enhanced efficiency, and robust performance. As solar installations continue to proliferate across the globe, the adoption of such advanced technologies will play a pivotal role in shaping a sustainable and resilient energy future.
