Description
The JA Solar 615 Watt solar panel (model JAM66D45-615/LB) is a premium, state-of-the-art photovoltaic module that combines cutting-edge n-type TOPCon technology with a bifacial glass-glass design for superior energy yield, low degradation, and long-lasting performance. Designed for modern solar power systems — including rooftop arrays, ground-mounted plants, and utility-scale installations — this panel offers high output and reliability even in challenging environmental conditions.
🔍 Key Features
-
⚡ High Power Output: Delivers up to 615 W of rated power per panel, allowing more energy generation in less space.
-
☀️ Advanced n-type TOPCon Cells: Provides excellent efficiency (≈22.8 %+) and reduced light-induced degradation (LID) for stable long-term output.
-
📈 Bifacial Energy Gain: Dual-glass construction enables capture of reflected light from the rear side, boosting overall energy harvest when installed over reflective surfaces.
-
🏋️♂️ Robust Durability: With high mechanical load ratings (e.g., ~5400 Pa front snow load, ~2400 Pa wind load), this panel withstands harsh climates and extreme weather.
-
