If you want a panel that performs hard, looks sharp, and delivers bifacial gains without the premium price tag, the Talesun BIPRO 415W All-Black is exactly that — 108 half-cut PERC cells in a sleek all-black finish with 5% to 25% additional rear-side energy yield depending on installation conditions.

• 10BB Half-Cut Cell Technology – New circuit design with lower internal current and reduced Rs loss delivers higher output with a Ga-doped wafer for first-year attenuation of just ≤2% and ≤0.55% linear degradation annually.
• Bifacial PERC for Industry-Leading Yield – Transparent backsheet captures rear-side irradiance for 5% to 25% more energy yield depending on albedo and ground conditions, lowering your overall LCOE by up to 2%.
• Excellent Anti-PID Performance – Tested to twice the industry standard Anti-PID requirement by TÜV SÜD for reliable long-term performance in humid and high-voltage environments.
• IP68 Junction Box with 3 Bypass Diodes – High waterproof protection and bypass diodes minimize power loss under shading conditions and protect cells from reverse current damage.
• 25-Year Linear Performance Warranty – Backed by a 12-year quality assurance warranty and a 25-year linear power output guarantee with 84.8% capacity retained at end of life.

The BIPRO all-black aesthetic sets this panel apart on any rooftop — uniform black frame, black backsheet, and black cells create a seamless look that high-end residential customers and installers demand without compromising a watt of output. The 3.2mm AR-coated tempered glass protects the 108-cell array against front-side mechanical loads up to 5,400 Pa and rear loads up to 2,400 Pa.

Weighing just 47.4 lbs in a slim 30mm profile, this panel is easy to handle on the roof and works across both 1000V and 1500V DC system configurations. The 70% bifaciality factor means real-world rear-side gains are predictable and bankable — not just a marketing number.

With IEC 61215, IEC 61730, and UL 61703 certifications plus ISO 9001, ISO 14001, and ISO 45001 quality system compliance, every Talesun BIPRO panel that ships is built to the same exacting standard — whether it's going on a residential rooftop or a commercial ground mount.
