TopCon vs HJT Solar Panels which is best New Technology?
In this blog post here we discuss about TopCon vs HJT Solar Panels which is best New Technology? Solar Panel industry no longer focused on increasing of wattage of panel. Now a days need more focus on more electricity then the same amount of space and here is the solution of advanced solar cell such as TOPCon and HJT. This Technology has more 25 plus % efficiency.
What is TOPCon Solar Panel Technology?
TopCon stands for Tunnel Oxide Passivated Contact. This technology is specially designed for to reduce energy losses. A thin layer of oxide layer help to improve of electrical charges and reducing recombination losses. TOPCon solar cells reduce very less of energy from sunlight.
Why is TOPCon Solar cells becoming Popular?
TOPCon solar cells becoming most popular because for high efficiency and it offers:
- It improved energy generation per square feet
- There is Good performance in limited solar space
- Lower less of solar cell and high efficiency and conventional modules.
- There is practical manufacturing pathway for existing silicon industry.
About HJT Solar Technology
HJT technology stands for Heterojunction Technology and a combination of crystalline silicon with thin layer semiconductor layers and creates heterojunction structure that may improve electrical charge that are collected. HJT Technology can offer a low temperature coefficient power and better hot operating conditions. There are some advantages of HJT Technology like
- High Efficiency
- Strong performance
- High quality paasivation
- Lower degradation
- Excellent long-term energy generation
Difference between HJT and TOPCon
| Features | TOPCon | HJT |
| Efficiency | High efficiency | commercial range |
| Temperature | Good | Excellent |
| Performance | Good | Strong |
| Full Form | Tunnel Oxide Passivated Contact | Heterojunction Technology |
| Manufacturing | silicon | different manufactures process |
| Man attraction | High efficiency production | High efficiency and strong temperature |
| Life Long | depends on climate and maintenance | same depends on climate and maintenance |
Conlusion
Both Technology offers strong combination of high efficiency and HJT Technology is particularly attractive for performance and high efficiency. The smartest approach is efficiency, temperature coefficient, warranty, price per watt. For homeowners and large scale business projects need more power, more land and suitable roof space areas. TOPCon and HJT solar panel technology continue working on advanced solar cell architecture. One of the biggest advantage is high efficiency for solar technology. Higher efficiency solar panel can be more valuable.
FAQ
Among TOPCon and HJT which one we should choose?
If you are installing solar for your home you don’t have to choose panel you should compare both like Module efficiency, temperature coefficient, degradation rate, price per watt, real world power output. Best choice depends on the projects, climate, roof space and depends on your budget.
Why temperature is important for solar panels?
As temperature of solar panel increase, its electrical performance. Hot region looking panel’s temperature coefficient and sometimes more useful than simply and TOPCon solar panel depends on panel based technology. HJT technology generally has strong temperature coefficient in hot climate.
Are higher efficiency panel have extra cost?
They have limited solar space and panel can produce more power from the same areas as compared to expected increase lifetime energy generations. 25 percent more efficiency does not mean your electricity generation or savings will automatically increase by 25 percent.
