    • 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.
