Powerwell Solar BW-SM255P 255W Polycrystalline Solar Panel
Model BW-SM255P | Polycrystalline | 60 Cells | Monocrystalline/Bifacial Not Specified | 1000V System Voltage
Product Overview
The Powerwell Solar BW-SM255P is a 255W polycrystalline solar panel designed for dependable daily energy generation. It combines a practical size, solid build quality, and stable electrical performance for a wide range of solar applications. The panel offers 15.67% efficiency and uses 60 cells for reliable power conversion. Its tempered glass front and aluminium frame help support long-term outdoor use. The module is suited for systems that need consistent output and straightforward installation. It is a strong choice for buyers seeking a balanced mix of value, durability, and performance.
Key Benefits
Reliable power output: The panel delivers a maximum power rating of 255Wp for steady energy production.
Practical efficiency level: Its 15.67% efficiency supports effective space use in residential and commercial setups.
Durable construction: Tempered glass and an aluminium frame provide strong protection in outdoor environments.
Wide temperature tolerance: The operating range supports performance from -40 to 90 °C.
Installation-friendly format: A 1000V maximum system voltage and standard cable length help simplify integration.
How It Works
The BW-SM255P converts sunlight into usable direct current electricity through its polycrystalline silicon cell structure. Sunlight hits the glass-covered surface, and the cells generate electrical energy across the module. The panel then sends power through its cables and junction box to the rest of the solar system. Its electrical values support stable operation under standard conditions. The design also accounts for temperature changes, which helps maintain predictable performance in real-world installations. This makes the module suitable for systems that need simple energy capture and reliable output.
Photovoltaic conversion: Solar radiation is absorbed by the polycrystalline cells, which produce electrical current. This creates the panel's core power output for the system.
Voltage and current delivery: The module operates at 30V Vmpp and 8.5A Impp under maximum power conditions. These values help define how the panel works with compatible solar equipment.
Thermal performance control: Temperature coefficients describe how output changes as heat increases. This helps users understand performance behavior in hot and cold conditions.
