Yes, you can purchase the Furrion 165W Rigid Monocrystalline RV Rooftop Solar Panel to run in parallel with your existing panel. Keep in mind that Furrion panels use proprietary connectors that may not be compatible with standard MC4 connectors, so wiring may require special harnesses or adapters. Additionally, ensure that both panels have matching voltage and current ratings to avoid inefficiencies or system damage. The panel does not include mounting hardware, so compatible brackets will need to be purchased separately. Also, verify that your current charge controller can handle the combined output of both panels; if not, an upgrade may be necessary. For safe and efficient installation, consulting a professional RV technician is highly recommended.
