How Efficient is HJT Solar Panel?

2023.03.15

Heterojunction (HJT) solar panels are the latest innovation in solar technology that promise higher efficiency and performance compared to conventional solar panels. In this article, we will explore the efficiency of HJT solar panels and why they are becoming increasingly popular in the renewable energy sector.


What are HJT solar panels?


HJT solar panels are made up of thin layers of amorphous silicon and crystalline silicon. The amorphous silicon layers are used to create the solar cells, while the crystalline silicon layers act as the conducting layers. This unique construction allows HJT solar panels to achieve higher efficiencies compared to conventional solar panels.


Efficiency of HJT solar panels


The efficiency of a solar panel refers to the percentage of sunlight that is converted into electricity. HJT solar panels have an efficiency rating of up to 24%, which is significantly higher than the average efficiency of conventional solar panels, which is around 15-18%.


The higher efficiency of HJT solar panels is due to several factors. Firstly, the amorphous silicon layers are highly efficient at absorbing sunlight, even in low light conditions. This means that HJT solar panels can generate electricity even on cloudy days or in the early morning and late afternoon when the sun's intensity is lower.


Secondly, the crystalline silicon layers act as a highly conductive layer, allowing for efficient electron flow and minimizing energy losses. This means that HJT solar panels can generate more electricity from the same amount of sunlight compared to conventional solar panels.


Why are HJT solar panels becoming popular?


HJT solar panels are becoming increasingly popular in the renewable energy sector for several reasons. Firstly, their higher efficiency means that they can generate more electricity from the same amount of sunlight compared to conventional solar panels. This means that fewer solar panels are needed to generate the same amount of electricity, making HJT solar panels a more cost-effective option in the long run.


Secondly, HJT solar panels are highly reliable and durable. They are designed to withstand extreme weather conditions, such as high winds and heavy snowfall, and have a longer lifespan compared to conventional solar panels. This means that HJT solar panels require less maintenance and have a lower risk of failure, making them a more reliable and cost-effective option for homeowners and businesses.


Thirdly, HJT solar panels are more aesthetically pleasing compared to conventional solar panels. They have a sleek, black appearance that blends in seamlessly with a variety of building styles, making them a popular choice for residential and commercial applications.
