Solraiser Bi-Fold Portable Solar Panel Our 300W monocrystalline solar panels are designed for efficiency and performance. The portable panels utilises the latest monocrystalline cell technology to enable a maximum 24% high module conversion rate. Other quality and safety features include a copper foundation, heavy-duty aluminium alloy frames with corner protectors, a waterproof MPPT regulator, high structural integrity tempered glass, adjustable standing fee and built-in overcharging protection. To reduce the drop in power due to shade and low light environment, a bypass diode enables the panels to maintain its solar absorption with minimal disruption. The panels carries German TUV certification for quality and reliability.
