Advantages of Radiance TOPCon Modules
The recombination of electrons and holes on the surface and any interface is the main factor limiting cell efficiency, and
various passivation technologies have been developed to reduce the recombination, from early-stage BSF (Back Surface Field) to currently popular PERC (Passivated Emitter and Rear Cell), latest HJT (Heterojunction) and nowadays TOPCon technologies. TOPCon is an advanced passivation technology, which is compatible with both P-type and N-type silicon wafers and can greatly enhance cell efficiency by growing an ultra-thin oxide layer and a doped polysilicon layer on the back of the cell to create a good interfacial passivation. When combined with N-type silicon wafers, upper efficiency limit of TOPCon cells is estimated to be 28.7%, outclassing that of PERC, which would be about 24.5%. TOPCon's processing is more compatible to the existing PERC production lines, thus balancing better manufacturing cost and higher module efficiency. TOPCon is expected to be mainstream cell technology in the coming years.
More Energy Yield
TOPCon modules enjoy better low-light performance. Improved low light performance is mainly related to the optimization of series resistance, leading to low saturation currents in TOPCon modules. Under low-light condition (200W/m²), performance of 210 TOPCon modules would be about 0.2% higher than 210 PERC modules.
Better Power Output
Modules’ operating temperature impacts their power output. Radiance TOPCon modules are based on N-type silicon wafers with high minority carrier lifetime and higher open-circuit voltage. The higher open-circuit voltage, the better module temperature coefficient. As a result, TOPCon modules would perform better than PERC modules when operating in high temperature environments.
Why choose our high power solar panel？
Q: Why choose high power solar panels?
A: High power solar panels have several advantages over traditional solar panels. First, they generate more electricity per square foot, capturing sunlight and generating energy more efficiently. This means you can generate more power with fewer panels, saving space and installation costs. In addition, the high-power solar panels are designed to withstand harsh weather conditions and have a longer service life, providing reliable clean energy for years to come.
Q: How do high power solar panels work?
A: High power solar panels work on the same principle as traditional solar panels. They use photovoltaic cells to convert sunlight into direct current electricity. These cells are made of semiconducting materials that generate electricity when exposed to sunlight. This power is then converted to alternating current (AC) by an inverter, which can be used to power home appliances, charge batteries, or be fed back to the grid.
Q: Can my home use high power solar panels?
A: Yes, high power solar panels are suitable for residential installations. In fact, they're especially beneficial for homeowners who have limited roof space but still want to maximize solar output. The increased efficiency of high-wattage panels allows you to generate more electricity with fewer panels, making them ideal for homes with limited roof area.
Q: What size high power solar panels do I need for my home?
A: The size of high power solar panels you need depends on a variety of factors, including your electricity usage and available roof space. It is recommended to consult a solar professional who can assess your specific requirements and help determine the right panel size for your home. They take into account factors such as your average daily energy use, your location, and the amount of sunlight your roof receives to give you the most accurate recommendations.
Q: Are high power solar panels more expensive?
A: While the initial cost of high power solar panels may be slightly higher than traditional solar panels, they can be a cost-effective long-term investment. Because of its higher efficiency, you can generate more electricity with fewer panels, reducing installation and maintenance costs. Plus, high-wattage panels often come with extended warranties and longer lifespans, leading to even greater savings over time. Additionally, potential energy savings and incentives offered by government programs can help offset the upfront costs.
