ESG New Energy ES-585W 585W Monocrystalline Solar Panel
Model ES-585W | Monocrystalline | 156 Cells | Mono | 1500V System Voltage
Product Overview
The ESG New Energy ES-585W is a high-output monocrystalline solar panel built for dependable energy generation. It delivers strong performance with 585 Wp maximum power and 20.94% panel efficiency. Its positive power tolerance of 0 to +1% supports consistent output. The module uses 156 cells and a robust 182×182 mm cell format. It is designed for projects that need reliable power, stable operation, and efficient use of space. The panel also supports demanding electrical environments with a 1500V maximum system voltage. Its durable construction and anti-reflection tempered glass help improve light capture and long-term reliability.
Key Benefits
High power output: The module provides 585 Wp, making it suitable for strong energy production targets.
Efficient space use: At 20.94% efficiency, the panel supports more generation from the available roof or ground area.
Positive tolerance: The 0 to +1% power tolerance helps ensure output is not below the rated value.
Durable construction: Tempered anti-reflection glass, PET materials, and an anodized aluminium frame support long service life.
Broad installation suitability: The 1500V system voltage and 25A fuse rating support modern utility, commercial, and large-scale systems.
How It Works
The ES-585W converts sunlight into usable electricity through monocrystalline photovoltaic cells. Light enters the module through anti-reflection coated tempered glass, which helps reduce surface reflection. That allows more sunlight to reach the cells. The cells then generate direct current electricity, which is collected and routed through the junction box. Three bypass diodes help maintain performance during partial shading and reduce power loss. The panel is built to operate across a wide temperature range, so it remains suitable for many climates and installation conditions.
Light capture: The anti-reflection tempered glass improves sunlight transmission. This helps the cells absorb more available light.
Power generation: The monocrystalline cells convert sunlight into electrical current. The module reaches 44.41V at maximum power and 13.18A current.
Protection and flow control: The junction box uses three diodes to reduce losses under shading. This helps preserve output and system stability.
