The Talesun BIPRO TD8G60M 120-cell series features advanced bifacial dual glass modules that redefine efficiency standards in challenging environmental conditions. The use of half-cut cell technology combined with bifacial activity allows for generating additional energy from reflected radiation, which is crucial when installing on high-albedo surfaces such as light gravel, sand, or white roof membranes. The glass-glass construction effectively eliminates the PID degradation problem and minimizes the risk of micro-cracks, which directly translates to exceptional mechanical durability and the longevity of the entire installation. These panels are primarily dedicated to commercial investors and photovoltaic farm developers seeking to maximize yields from every square meter of surface area. Unlike standard monofacial modules, the BIPRO TD8G60M series offers significantly better temperature stability and a longer warranty for linear power output degradation. Thanks to the use of multi-busbar technology, current flow is optimized and resistive losses are kept to a minimum. Choosing this solution is a secure investment in energy security and a faster return on capital thanks to increased light absorption even at low sun angles.

Common questions

6 answered
Is the Talesun BIPRO TD8G60M 120-cell series still available for purchase?
The BIPRO TD8G60M 120-cell series has been discontinued by Talesun and replaced by newer, higher power-density models. Availability is now limited to remaining distributor stock. Ask your supplier about current inventory and manufacturing date, since bifacial glass-glass modules do not lose significant lifespan from warehouse storage time.
How much extra energy do the BIPRO TD8G60M bifacial panels actually generate?
Thanks to bifacial dual-glass technology, these panels capture additional reflected irradiance on the rear side. In practice, when mounted over light-colored gravel, concrete, or white roofing membranes, the extra yield can range from 5 to 15 percent compared to a monofacial module of the same 605 Wp nominal rating. The actual gain depends on mounting height, tilt angle, and ground albedo.
What warranty does Talesun offer on the BIPRO TD8G60M series and what does it cover?
Talesun provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. This means the manufacturer guarantees a minimum energy production level over three decades, which is an important factor when calculating return on investment for commercial installations and solar farms.
How do half-cut PERC cells in this series differ from standard full-size cells?
Half-cut PERC cells reduce resistive losses because current travels a shorter distance, and smaller cells generate less heat. As a result, the panel handles partial shading better, loses less power at high temperatures, and shows higher mechanical resistance to microcracks compared to modules with full-size cells.
Does the glass-glass construction of the BIPRO TD8G60M require special mounting structures?
Dual-glass panels are heavier than standard backsheet modules, so the mounting structure must be properly sized for the extra load. The benefit is that some variants can be frameless, and the panel offers much higher resistance to PID and moisture, making it suitable for ground-mount or flat-roof installations with light-colored surfaces to maximize the bifacial effect.
Are Talesun BIPRO TD8G60M panels suitable for large-scale commercial projects?
Yes, the series was primarily designed for solar farms and commercial installations where maximizing yield per square meter matters most. Up to 605 Wp per module, multi-busbar technology reducing resistive losses, and strong temperature stability make these panels well-suited for large ground-mount systems, though since production has ended, availability in large volumes may be limited.
