535w 540w 545w 550w 555w Double Glass Fully Transparent Pv Bifacial Solar Panel

The solar panels have a total output of 555W and come with a 12-year product warranty and a 25-year performance warranty. Thanks to the 210mm PERC cells, the module efficiency is 21.7%. You can generate a lot of green electricity if you set up the system in a sunny location.


    Solar panels are an essential component of a solar power system, and they are becoming increasingly popular as a source of renewable energy. The Sunnal solar panels have a power rating of 530W to 550W, making them ideal for residential and commercial applications.

    Overall, the Sunnal solar panels offer high power output, efficient energy conversion, and cost-effective pricing. They are an excellent choice for anyone looking to reduce their carbon footprint and harness the power of the sun to generate clean energy.

    Monocrystalline 1ug2


    • Positive tolerance of up to 5W delivers higher output reliability.
    • Higher module conversion efficiency(up to 21.46%) benefit Ammeter Rear Contact (PERC) technology.
    • Advanced glass and solar cell surface texturing allow performance in low-light environments.
