The Talesun BIPRO 415W is an all-black bifacial PERC panel built from 108 half-cut cells. Its transparent backsheet captures rear-side light for 5% to 25% extra yield depending on albedo and mounting height, which lowers lifetime energy cost. The uniform black frame, backsheet and cells make it a clean fit for visible residential rooftops. Against mainstream monofacial all-black panels it adds bifacial gain and a 25-year linear warranty, but the rear-side bonus only pays off with a reflective roof or elevated mounting.

The Talesun BIPRO 415W is a bifacial solar panel with 108 half-cut monocrystalline PERC cells and an all-black look. The frame, backsheet and cells are all black. The transparent backsheet lets the rear side capture reflected light, which adds 5% to 25% more energy depending on albedo and ground conditions. The bifaciality factor is 70%.
The panel uses 10BB half-cut cell technology with a Ga-doped wafer. First-year degradation is 2% or less, and linear degradation is 0.55% or less per year. The front glass is 3.2mm AR-coated tempered glass. It is rated for front mechanical loads up to 5,400 Pa and rear loads up to 2,400 Pa.
The IP68 junction box has 3 bypass diodes to limit power loss under shading and protect cells from reverse current. The panel weighs 47.4 lbs and has a 30mm profile. It works with both 1000V and 1500V DC systems. It is certified to IEC 61215, IEC 61730 and UL 61703, and is covered by a 12-year quality assurance warranty and a 25-year linear performance warranty.
