High-performance Talesun BISTAR TP7F72M / TP7F72M(H) modules are designed for high performance in real-world operating conditions - even under partial shading and uneven irradiation. The applied half-cut cell technology and 10BB busbar structure reduce connection losses and improve module performance under higher current loads, translating to a more stable energy yield. Another notable feature of this series is the gallium-doped silicon wafer, which helps limit degradation and maintain parameters over a long service life. The manufacturer also highlights lower hot-spot risk due to special circuit construction, which is crucial for installations exposed to local shading (e.g., chimneys, roof ridges, trees). The entire package is complemented by PID resistance confirmed by extended TÜV SÜD testing and a robust IP68-rated junction box, important for long-term rooftop operation. This is an excellent choice for utility-scale PV farms, commercial rooftops, and large-scale residential systems, where reliability and low energy cost-of-ownership over the lifetime are key.

Common questions

6 answered
Are Talesun BISTAR TP7F72M / TP7F72M(H) panels still available for purchase?
The BISTAR TP7F72M / TP7F72M(H) series has been discontinued from Talesun's current production lineup. Panels may still be available in limited quantities from distributors as remaining stock, but the manufacturer no longer offers this model as part of its standard range. For larger installations, it's worth confirming availability and delivery timelines with your supplier in advance, as remaining inventory can sell out quickly.
What warranty comes with Talesun BISTAR TP7F72M panels?
As a Tier 1 manufacturer, Talesun provides a 12-year product warranty and a 25-year linear power output warranty on the BISTAR TP7F72M series. This is a market-standard offering for high-quality PERC modules, meaning that after 25 years the panel should still generate a significant share of its original rated power - an important factor when calculating the return on investment of a PV installation.
What are half-cut technology and the 10BB layout on BISTAR TP7F72M panels, and are they worth it?
Half-cut cells are cut in half, reducing current losses and internal resistance within the module, while the 10-busbar (10BB) layout improves current collection across the cell surface. Together these technologies cut energy losses, increase resistance to microcracks, and improve panel performance under partial shading, such as from a chimney or antenna. These are proven technologies that translate into more stable energy yields.
Are BISTAR TP7F72M panels resistant to PID degradation and hot spots?
Yes, the series uses a gallium-doped silicon wafer that reduces light and elevated temperature induced degradation (LeTID) and helps maintain stable performance over time. Resistance to Potential Induced Degradation (PID) has been additionally confirmed by an extended TÜV SÜD test. A special circuit design also lowers the risk of hot spots under localized shading, extending the module's trouble-free service life.
Is the Talesun BISTAR TP7F72M series suitable for large PV farms and commercial roofs?
Yes, power output of up to 550 Wp, an IP68-rated sealed junction box, and confirmed PID resistance make the BISTAR TP7F72M series well-suited for PV farms, commercial roofs, and large prosumer installations. Low levelized cost of energy (LCOE) and long-term parameter stability are key advantages for investors evaluating project profitability over a 20-25 year horizon.
What is the maximum power output of the BISTAR TP7F72M panel, and how does it compare to other PERC modules?
Models in the BISTAR TP7F72M series reach a maximum power output of up to 550 Wp, placing them in the high-performance tier for PERC technology. The panels are not bifacial - they generate power only from the front surface, which is typical for most standard rooftop and ground-mount installations where the absence of a reflective ground surface would limit the benefits of bifacial technology anyway.
