Description
xOptimize your project's return on investment and energy yield with the JA Solar 620W Bifacial TOPCon Solar Panel (JAM66D45-620-LB). Part of the highly acclaimed DeepBlue 4.0 Pro series, this high-capacity industrial module combines n-type TOPCon half-cut cell architecture with a premium double-glass bifacial layout. By absorbing direct sunlight from the front while generating up to an additional 25% power from ambient ground reflection on the rear, this panel offers exceptionally low levelized cost of energy (LCOE) for large commercial rooftop and ground-mounted arrays. ☀️
🚚 LTL Freight Delivery Required
Due to the commercial weight and oversized dimensions of these industrial double-glass panels (73.2 lbs / 33.1 kg each), they must ship via specialized LTL freight transport to prevent transit damage. Standard checkout shipping rates do not apply. Please Contact Us with your delivery postal code for a personalized freight quote before completing your order!
Key Features & Performance Benefits
- Staggering 620W Continuous Output: Premium 16BB multi-busbar cell layouts provide massive power density, effectively lowering balance-of-system (BOS) costs by minimizing required mounting racking, cabling, and installation labor hours. ⚡
- Exceptional 23.0% Module Efficiency: State-of-the-art n-type TOPCon cells deliver high area efficiency and capture reliable power output even under tricky overcast or low-irradiance lighting conditions.
- 80% Dual-Glass Bifaciality Factor: Outfitted with 2.0mm front and rear tempered glass sheets to capture reflected ground light, boosting aggregate energy production depending on your mounting surface albedo (such as light gravel, sand, or snow). 🔋
- Resilient Anti-Degradation Profile: Advanced cell doping provides protection against Light-Induced Degradation (LID) and LeTID, securing a minimal 1% drop in the first year and an ultra-low 0.4% annual degradation over its long lifetime.
- Heavy-Duty Structural Rating: Engineered with a sturdy 30mm anodized aluminum alloy frame certified to effortlessly withstand an extreme 5400 Pa front snow load and 2400 Pa rear wind load. 🏔️
