Products Description
570W High Power Output & Efficiency
Industry-Leading Wattage: Generates 570W of peak power, outperforming standard 400–500W panels by 14–42% in energy yield per unit area. This reduces the number of panels needed for target capacities: a 10kW system requires just 18 panels (vs. 25+ with 400W panels), cutting installation time, hardware costs, and space usage.
Premium Conversion Efficiency: Boasts a conversion efficiency of up to 23.0%, achieved through PERC (Passivated Emitter and Rear Cell) technology and half-cut monocrystalline cells. This minimizes energy loss by enhancing light absorption and reducing electrical resistance, ensuring more sunlight is converted into usable electricity.
Double Glass Construction for Unmatched Durability
Twin Glass Layers: Features two sheets of tempered, low-iron glass (front and back) instead of a traditional plastic backsheet. This design eliminates degradation from UV radiation, moisture, or chemical exposure-common issues with standard panels in humid or coastal areas.
Enhanced Weather Resistance: Withstands extreme conditions, including:
Hail Impact: Resists 25mm hail stones (higher than the 20mm industry standard).
Wind & Snow Loads: Handles 140mph+ winds and 5400Pa snow loads, suitable for high-altitude or storm-prone regions.
Corrosion Resistance: Ideal for coastal areas, as glass is impervious to salt spray, unlike plastic backsheets that degrade over time.
Longer Lifespan: Double glass protects cells from physical damage (e.g., from debris or foot traffic during installation), extending the panel's lifespan to 30+ years-5–10 years longer than standard panels.
Advanced Cell Technology for Reliable Performance
Half-Cut & Multi-Busbar Design: Cells are split into smaller segments to reduce current loss and improve performance in partial shading (e.g., from trees, chimneys, or clouds). This design ensures the panel retains 80%+ of its power under shading, a critical advantage for urban or tree-lined properties.
Temperature Tolerance: Features a low temperature coefficient (-0.34%/°C), meaning it loses minimal output in hot weather-vital for sunny regions where panel temperatures can exceed 60°C.
Low-Light Efficiency: Excels in diffused sunlight (dawn, dusk, cloudy days) due to its high-quality monocrystalline cells, ensuring consistent energy production across diverse climates.

FAQ
How do I clean this kind of solar panel?
Use a soft brush or sponge with mild detergent and water. Gently scrub the surface to remove dirt, dust, and bird droppings. Avoid using abrasive materials or harsh chemicals that could scratch or damage the glass surface. Rinse thoroughly with clean water and let it dry naturally. It is recommended to clean the panel regularly, especially in dusty or dirty environments, to maintain its power generation efficiency.
What is the temperature coefficient of the solar panel?
The temperature coefficient indicates how the panel's power output changes with temperature. For most double-glass solar panels, the power output decreases as the temperature rises. Typically, the temperature coefficient is around - 0.3% to - 0.4% per degree Celsius. This means that for every 1-degree Celsius increase in temperature above the standard test condition (usually 25 degrees Celsius), the power output of the panel will decrease by about 0.3% - 0.4%.
