REC 375 Watt Alpha Solar Panel - REC375AA
375-Watt monocrystalline solar panel with unparalleled efficiency and power density.
REC Alpha Solar Panel Description:
REC's Alpha series is engineered for excellent energy density and is one of the world's most powerful 60-cell solar modules. This 375W REC Alpha solar panel achieves a power density of 19.9 Watts per square foot and a STC efficiency of 21.4%.
Like the REC TwinPeak modules it's based on, the REC Alpha 375 solar panel uses a "half-cut" PV cell design, splitting the panel into twin sections to lower electrical resistance and allow for continued power production in partial shade conditions. But unlike the TwinPeaks, the Alphas feature REC's heterojunction (HJT) cell technology. These monocrystalline cells are solder-free and feature more wiring between cells for improved current flow.
In addition to power density and efficiency, the other area where the REC Alpha separates itself from the pack is with its super-strong frame. While made of the standard anodized aluminum found in most solar panel frames, the Alpha frames are reinforced by two rear support bars, allowing them to handle snow loads of up to 7000 Pa instead of the industry-standard 5400 Pa.
REC Alpha Solar Panel Features:
- Incredible 21.4% module efficiency
- For off-grid or grid-tied use
- 120 half-cut monocrystalline cells with heterojunction technology for exceptional power density
