The Talesun TD7G72M (BIPRO) series, featuring a 144-cell configuration rated between 530-550W, are bifacial PERC modules. Their unique design harnesses energy from both sides, significantly boosting energy yield by generating power from the rear side as well - particularly effective in environments where the substrate reflects light effectively (e.g., light gravel, roof membranes, concrete). The application of half-cut technology combined with a multi-busbar (MBB) configuration enhances performance under partial shading and minimizes internal losses, resulting in a more consistent energy output throughout the day. In practice, these panels effectively address performance drops in challenging conditions, thanks to their improved PID resistance and a robust construction designed for operation in humid, windy, and dusty environments. Another key feature is their double-sided structure, which increases durability and resistance to micro-cracking - crucial for projects demanding high reliability. This makes them an excellent choice for utility-scale solar farms, large commercial rooftops, and industrial installations, where lower energy costs and predictable energy generation are paramount.

Common questions

6 answered
Is the Talesun TD7G72M (BIPRO) 530-550W series still available to purchase?
No, the TD7G72M (BIPRO) 144-cell 530-550W series has been discontinued by Talesun. Modules may still be available in limited quantities through distributor stock, but for new projects it is worth checking current inventory or considering the manufacturer's current lineup, such as its TOPCon-based series. The product warranty remains valid for units already purchased and installed.
How much extra energy does the bifacial design of the Talesun TD7G72M panels actually generate?
Real-world gains from rear-side generation depend on the ground surface and mounting height, but typical installations over light gravel, roofing membrane, or concrete can see an additional few to low-double-digit percentage of energy yield per year compared to a monofacial module of the same rating. Higher albedo surfaces and greater ground clearance both increase the rear-side contribution.
What does half-cut cell technology with multi-busbar design actually improve compared to standard cells?
Half-cut cells are cut in half, reducing current losses and internal resistance, while additional busbars distribute current more evenly across the cell. In practice this means smaller power drops under partial shading, such as from a chimney or a fallen leaf, and more stable energy output throughout the day compared to older full-cell modules.
What warranty comes with the Talesun TD7G72M series and what does it cover?
The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty guaranteeing a minimum percentage of the original power output over time. This is standard for Tier 1 modules and gives project developers predictable yields for long-term utility-scale and commercial installations.
Are the TD7G72M (BIPRO) panels suitable for harsh environments, such as coastal or high-humidity regions?
Yes, the series is built with enhanced PID (potential-induced degradation) resistance and a design suited to humid, windy, and dusty environments. The dual-glass construction further improves resistance to microcracks and corrosion, making these modules a solid choice for utility-scale PV farms and industrial installations operating in demanding climates.
Is the dual-glass construction of these panels heavier and harder to install than standard modules?
Dual-glass modules are typically somewhat heavier than backsheet panels, which should be factored into the mounting structure design, especially on rooftops. In exchange, they offer higher resistance to microcracks, moisture, and long-term degradation, which for large PV farms and industrial installations translates into lower failure risk and more stable yields over a 25-30 year lifespan.
