550W Mono PERC Half-Cell Solar Panel: High-Efficiency Clean Energy for Every Scenario

In an era where sustainable energy is no longer an option but a necessity, the 550W Monocrystalline PERC Half-Cell Solar Panel emerges as a game-changer. Designed to balance maximum power output, durability, and versatility, this solar panel transforms sunlight into reliable electricity for residential, commercial, and off-grid applications—helping you cut energy costs while reducing your carbon footprint. Whether you’re aiming to achieve energy independence, lower operational expenses, or embrace eco-friendly living, this panel delivers performance that exceeds expectations.

1、550W High Power & 21%+ Efficiency: More Energy, Less Space

At the core of this solar panel lies advanced technology that delivers exceptional performance. Its 550W peak power ensures robust energy production, capable of meeting the daily electricity needs of a typical household—powering everything from lighting and appliances to HVAC systems—or efficiently running commercial equipment like warehouse machinery and office devices.

Equipped with mono PERC (Passivated Emitter and Rear Cell) technology, the panel achieves a conversion efficiency of up to 21.3%. This means it captures more sunlight and converts it into usable energy, even in low-light conditions like cloudy days, early mornings, or late afternoons. The half-cell design further enhances performance by splitting standard solar cells into two, reducing electrical resistance and minimizing energy loss—especially under partial shading from trees, chimneys, or nearby buildings. This ensures consistent power generation even when part of the panel is covered, a common pain point with traditional solar modules.

Thanks to the integration of 182mm large-format silicon cells (144 pieces arranged in 6×24 configuration), the panel boasts higher power density. It generates more electricity per unit area, allowing you to install fewer panels to meet your energy goals—saving valuable roof space for residential properties or maximizing energy output for commercial buildings with limited installation areas, while also cutting down on installation labor costs.

2、Durable Construction: Built to Withstand the Elements

This 550W solar panel is engineered for longevity, with a robust build that stands up to harsh environmental conditions, making it a reliable investment for decades.

• High-Quality Materials: The front surface features 3.2mm high-transmittance tempered glass that resists scratches, impacts, and UV radiation, ensuring optimal light absorption over time. The backsheet is made of weather-resistant EVA film composite material, while the sturdy anodized aluminum alloy frame provides strong structural stability and corrosion resistance—perfect for coastal areas with high salt content in the air.

• Extreme Weather Resilience: With an IP68-rated junction box (equipped with 3 bypass diodes) and sealed connectors, the panel offers excellent waterproof and dustproof protection. It operates reliably in temperatures ranging from -40°C to 85°C, adapting to frigid winter nights and scorching summer days. Additionally, it passes 5400Pa front snow load and 2400Pa back wind load tests, capable of withstanding heavy snowfall and strong gusts without damage.

• Low Degradation & Anti-PID Protection: Adopting low LID (Light-Induced Degradation) mono PERC technology, the panel’s power degradation is less than 2% in the first year and only 0.55% annually from years 2 to 25. Moreover, through battery production technology optimization and strict material control, the attenuation rate caused by PID (Potential Induced Degradation) phenomenon is minimized, ensuring consistent energy output and a long service life of over 25 years.

3、Versatile Applications: Power for Every Need

Whether you’re looking to power your home, business, or off-grid projects, this 550W solar panel adapts seamlessly to diverse scenarios, supported by comprehensive certifications including IEC61215, IEC61701, IEC61730, and ISO management system standards.

• Residential Rooftops: Ideal for homeowners aiming to reduce electricity bills and achieve energy independence. It integrates smoothly with residential solar systems, compatible with mainstream inverters and mounting structures, and its sleek design blends well with most roof styles.

• Commercial & Industrial Use: Perfect for warehouses, factories, and commercial buildings. Its high power output and efficiency help businesses lower operational costs, meet corporate sustainability goals, and even qualify for green energy incentives. The panel’s scalability makes it easy to expand the system as energy needs grow.

• Off-Grid Systems: A reliable power source for remote cabins, RVs, and outdoor work sites (such as construction zones or geological survey stations). Pair it with a battery storage system to ensure continuous electricity supply in areas without grid access, keeping essential devices and equipment running.

• Large-Scale Installations: Suitable for ground-mounted solar farms and commercial projects. With a packing volume of 3.372Cbm per pallet and 620 pieces fitting in a 40’HQ container, it’s easy to transport and install in bulk, helping minimize BOS (Balance of System) costs and improve overall project ROI.
