ESG New Energy 545W TOPCon Solar Panel
Model 545W | TOPCon | 144 Cells | Mono | 1500V System Voltage
Product Overview
The ESG New Energy 545W solar panel is built for dependable power generation and strong long-term value. It uses TOPCon technology to support high output and efficient energy conversion. With a rated maximum power of 545 Wp, it is well suited to commercial and utility-scale solar projects. The module offers 21.1% efficiency, helping maximize energy yield in limited space. Its 144-cell design, tempered glass construction, and anodized aluminium frame support reliable performance in demanding environments. The 10-year product warranty adds confidence for buyers seeking a practical and efficient solar solution.
Key Benefits
High power output: The module delivers up to 545 Wp for strong solar production.
Efficient energy conversion: Its 21.1% efficiency helps improve energy harvest from available roof or ground space.
TOPCon technology: Advanced cell technology supports modern performance expectations and stable output.
Robust construction: Tempered glass, PET back cover, and an aluminium frame enhance durability.
Installation-friendly design: The 32 kg weight and MC4 connector support practical handling and setup.
How It Works
This solar panel converts sunlight into electricity through advanced photovoltaic cells. The TOPCon cell structure helps reduce energy loss and improve conversion efficiency. When sunlight reaches the module, the cells generate direct current for use in solar systems. The electrical output is then matched through maximum power point values, which help the panel operate efficiently under real conditions. Its temperature coefficients show how performance changes as heat rises. The design also combines mechanical strength with weather-resistant components, helping the module remain stable during long-term operation.
Photovoltaic conversion: Sunlight is captured by the cells and turned into usable electrical energy. The 144-cell layout supports consistent power generation.
Electrical output balance: Vmpp, Impp, Voc, and Isc values define how the module performs under operating and test conditions. These values help system designers match the panel correctly.
Environmental stability: The temperature coefficients describe how output changes in higher heat. The IP68 junction box and durable materials support outdoor use.
