640-670W Monocrystalline Solar Panel
Product Description
Monocrystalline solar panels are made with advanced silicon cells that have been engineered to provide the highest level of efficiency in converting sunlight into electricity. These panels are known for their distinctive uniform black color, which is a result of the single-crystal structure of silicon cells. This structure allows monocrystalline solar panels to absorb sunlight more efficiently and generate higher power output, maintaining high efficiency even in low-light conditions.
With monocrystalline solar panels, you can power your home or business while reducing your carbon footprint and reliance on traditional energy sources. By harnessing the power of the sun, you can create a cleaner, greener future for generations to come. Whether you want to install solar panels on your roof or integrate them into a large commercial solar project, monocrystalline solar panels are the perfect choice for maximizing energy efficiency and sustainability.

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.
