The Talesun BISTAR TP7F78M / TP7F78M(H) (580-600W) series is designed for high energy output where every square meter of roof or structure counts. The application of heterojunction technology combined with the 10Busbar wiring system improves module performance under partial shading and helps minimize losses in daily operating conditions. The manufacturer also highlights the special circuit construction that reduces the risk of hot spots, ensuring greater safety and stable yields in installations exposed to uneven sunlight.

Another key feature of this series is the enhanced resistance to PID and robust construction with an IP68 junction box, which facilitates designing systems in environments with high humidity and dust. This is an excellent choice for installers working on commercial and industrial systems, as well as investors seeking reliable module performance and lower energy costs throughout the installation's lifecycle.

Common questions

6 answered
Is the Talesun BISTAR TP7F78M / TP7F78M(H) series still available for purchase?
The BISTAR TP7F78M / TP7F78M(H) (580-600W) series has been discontinued by Talesun and replaced by newer models built on TOPCon technology. Panels may still be found through distributors as remaining stock, but with no guarantee of continued supply for expanding existing installations. For larger projects, check current availability with your supplier and consider the manufacturer's current lineup instead.
What warranty applies to Talesun BISTAR TP7F78M panels?
The manufacturer covers the series with a 12-year product warranty and a 25-year linear power output warranty. This means that after 25 years of operation the module should still generate a significant share of its original rated power. As a tier 1 manufacturer, Talesun provides service support in line with the terms of the warranty card, which is standard for commercial and industrial-grade panels.
How does 10BB technology in BISTAR TP7F78M panels differ from standard modules?
The 10BB layout means ten busbars on each half-cut cell, reducing series resistance and current losses inside the module. Combined with half-cut PERC cell technology, this improves module performance under partial shading and helps maintain higher energy conversion efficiency in real-world conditions, for example under soiling or shade cast by chimneys.
Are Talesun BISTAR TP7F78M panels suitable for installations in humid climates?
Yes, the series features enhanced resistance to potential-induced degradation (PID) and a robust junction box rated IP68. This makes the modules well-suited to installations exposed to high humidity, dust, or variable weather conditions, making them a good choice for commercial and industrial projects outside typical temperate climates.
Are BISTAR TP7F78M panels bifacial modules?
No, the TP7F78M / TP7F78M(H) series consists of monofacial panels using PERC cell technology. They generate energy only from irradiance hitting the front side of the module directly, without the additional rear-side gain typical of bifacial panels. This makes them simpler to install and sufficient for most standard rooftop and ground-mount installations.
What kind of installations are best suited to Talesun BISTAR TP7F78M panels rated up to 600W?
With a high unit power of up to 600 Wp, these panels are best suited to large commercial and industrial installations where maximizing energy output on limited roof or ground area matters. Fewer modules needed to reach a given installed capacity lowers mounting structure, cabling, and labor costs per kilowatt installed.
