S-Energy SL45-72BGI-455S 455W Monocrystalline Bifacial Solar Panel
Model SL45-72BGI-455S | Monocrystalline | 144 Cells | Bifacial | 1500V System Voltage
Product Overview
The S-Energy SL45-72BGI-455S is a high-performance 455W bifacial solar panel built for dependable energy production. It combines monocrystalline cell technology with a bifacial design to capture light from both sides. This helps increase yield in suitable installations. The module offers a strong 20.9% efficiency rating and a compact 144-cell layout. Its durable construction supports long-term outdoor use. The panel is designed for residential, commercial, and larger solar projects. It also features a 12-year product warranty and a 25-year power warranty. With quality materials and stable electrical performance, it is a practical choice for efficient solar generation.
Key Benefits
High power output: Delivers 455W of rated maximum power for strong energy production.
Bifacial generation: Uses both front and rear-side light to improve output in the right installation conditions.
High efficiency: Reaches up to 20.9% module efficiency for better use of available roof or ground space.
Durable construction: Includes tempered anti-reflection glass, an anodized aluminum frame, and IP68 protection.
Long warranty support: Backed by 12 years of product coverage and 25 years of power warranty protection.
How It Works
This module converts sunlight into electricity through monocrystalline photovoltaic cells. Its bifacial design allows the rear side to absorb reflected light. That can increase total generation when the panel is mounted over bright surfaces. The panel operates with a maximum system voltage of 1500V, which suits modern solar installations. It uses 144 cells arranged for stable voltage and current performance. The anti-reflection glass helps improve light capture on the front surface. At the same time, the three-bypass-diode junction box supports safer performance under partial shading. The result is a reliable solar module designed for efficient daily energy harvesting.
Front-side conversion: Sunlight enters through tempered anti-reflection glass and reaches the monocrystalline cells. The cells convert that light into electrical energy with high efficiency.
Rear-side gain: Reflected light from the installation surface is captured by the back side. This adds extra yield in favorable mounting conditions.
Power delivery and protection: The junction box, bypass diodes, and MC4 connectors support steady current flow. They also help reduce losses and maintain safer operation.
