If you want a solar panel with higher efficiency and better performance, choose TOPCon solar panels. Despite technological advancements, the TOPCon series solar panels have been widely used for many years. In this blog, we will discuss all about TOPCon solar panel technology and its benefits.
The TOPCon solar panels’ advanced cell structure makes them the best option in the Indian market. Furthermore, their longevity contributes to maintenance being less costly and the return on investment on solar installation being higher. First of all, let us understand the TOPCon technology in solar panels.
How does TOPCon Solar Panel Technology work?
The TOPCon solar panel technology was first presented in 2013 by Fraunhofer ISE, a European research institute (source). Over the years, this technology has improved to offer more than 25% efficiency in solar panels.
TOPCon is an acronym representing Tunnel Oxide Passivated Contact technology, which minimizes recombination losses and thus increases conversion of electric power. A super-thin tunnel oxide layer is placed between the solar cells and the metal layer at the back of the solar panel. This layer diminishes the electronic loss to a great extent, thereby boosting the electricity output.
Furthermore, the TOPCon solar panels use N-type silicon wafers to create the solar cells. This improves the temperature coefficient of the panels. Thus, it can perform well in both lower and higher temperatures, making it perfect for the Indian climate.
The TOPCon solar panel technology is designed to increase the sunlight conversion and reduce the loss of electrons to increase the total output of the solar system. Additionally, they work well in smart solar systems and bifacial designs.
What are the benefits of TOPCon Solar Panels?
The TOPCon solar panels are slightly pricy compared to the traditional solar panel technologies, and yet more people are choosing them. Here’s why the TOPCon solar panels have become the classic choice for solar panel installation.
Higher efficiency for better electricity output
The TOPCon solar panels are designed to reduce electron loss to increase the solar panel output. While the traditional Monocrystalline solar panels provide an efficiency of 22%, the TOPCon technology has an efficiency of more than 25%. Thus, you can generate more electricity in the same space. The TOPCon solar panels enable you to install solar panels even in a small space.
Slower degradation rate
The TOPCon solar panels are made with n-type wafers. Therefore, it has a greater advantage against the degradation of the cells. The attenuation rate of the TOPCon solar panel is 1% for the first year and reduces to an average of 0.4% in the later years.
In simple words, the TOPCon solar panels have a longer life cycle compared to the other options. On average, the TOPCon solar panels perform well for 25-30 years. Both residential and commercial solar projects can get better ROI in the form of free electricity for more than 20 years after the payback period.
Low temperature coefficient
While the solar panels need sunlight to function, excessive heat can damage the cells due to overheating. Therefore, many solar panels’ efficiency often drops a little in summer or on hot days. The passivated layers reduce the overheating in the cells to manage the efficiency. Thus, TOPCon series solar panels are perfect for the ever-changing Indian weather.
Better performance with a bifacial design
The passivated layer is thin enough to let the sunlight pass through. Therefore, they are perfectly compatible to create bifacial solar panels to increase your solar system’s output significantly. When you add a reflective layer to the rear of the solar panel, the cells get more exposure to sunlight, increasing solar energy production. They are perfect for people who have limited space and want to switch to solar energy.
Eco-friendly energy generation
The TOPCon solar panel technology is known for offering better efficiency and lifespan. Therefore, not only reduces the reliance on fuel-based energy but also reduces the need to change the panels. It helps us reduce the carbon footprint significantly and takes us one step closer to achieving Net-Zero status by 2070.
