    • Q

      What is the actual power output I can expect from these flexible panels?

      A

      The actual power output depends on several factors including sunlight conditions, temperature, installation angle, and panel maintenance. Under standard test conditions (STC), you'll get the rated power, but real-world conditions typically yield 85-90% of rated capacity.
    • Q

      What types of surfaces or structures are best suited for installing flexible solar modules?

      A

      They’re ideal for curved or irregular surfaces like RV roofs, boats, carports, tents, and low-load rooftops where traditional panels might not fit or add too much weight.
    • Q

      What are the main advantages of choosing flexible solar modules over rigid panels?

      A

      Flexible modules are lighter, easier to install on curved or irregular surfaces, and have a low-profile design. They’re also portable and versatile, making them ideal for unique or space-constrained projects.
    • Q

      What are the common applications for flexible solar modules?

      A

      They’re widely used on RVs, boats, carports, tents, and low-load rooftops, as well as in portable and off-grid systems.
    • Q

      What are the key specifications of Sunpal's flexible solar modules, such as power output, efficiency, and dimensions?

      A

      Sunpal’s flexible solar modules offer power outputs ranging from 100W to 500W, with efficiency ranging from 18.47% to 20.21%. Dimensions vary by model, and detailed specs are available on individual product pages.
    • Q

      What is the expected lifespan of Sunpal's flexible solar modules?

      A

      Sunpal manufactures solar panels; well, they’re built to last 25-30 years, matching rigid panels, with performance warranties ensuring at least 80% efficiency after 25 years.

    How do flexible solar modules perform in different environmental conditions, such as low light or high temperatures?

    They excel in low-light conditions and have a lower temperature coefficient, meaning they maintain efficiency in hot climates better than some rigid panels. Performance depends on the specific model. The table below details performance across conditions, with metrics and tips:

    Environmental Condition

    Performance Metrics/Details

    Optimization Tips/Impacts

    Low Light (Cloudy/Shaded)

    Retains 80-90% output; monocrystalline cells capture diffuse light effectively

    Use in urban or forested areas; bypass diodes minimize shading losses

    High Temperatures (>40°C)

    Temperature coefficient -0.3%/°C; less efficiency drop (5-10% vs. 15-20% for rigid)

    Ideal for tropical/marine use; ETFE layer dissipates heat faster

    Cold/Extreme Lows (-40°C)

    Stable operation; no freezing issues with flexible materials

    Suitable for winter camping; output may increase slightly in cold due to better conductivity

    High Humidity/Rain

    IP67/IP68 waterproof rating; no water ingress

    Marine applications thrive; clean regularly to prevent dust buildup

    Windy/Vibrating Areas

    Flexible design absorbs vibrations; withstands winds up to 150-200 km/h

    Great for vehicles; secure mounting prevents flapping

    Dusty/Dirty Environments

    ETFE surface resists dust adhesion; self-cleaning in rain

    Minimal efficiency loss (2-5% vs. 10% for glass); wipe with soft cloth periodically
