550 Watt Rigid Solar Panel - HPBC 26.0% High Efficient Cells
Power More with Less Space
Experience exceptional solar performance with the 550 Watt Rigid Solar Panel, built with advanced LONGi HPBC (Hybrid Passivated Back Contact) solar cells, one of the most efficient solar technologies available today. Delivering an impressive 26% cell efficiency, this high-output panel is designed for boaters, cruisers, van owners, and off-grid users who demand maximum power production and long-term reliability.
Engineered for superior energy harvest, the HPBC cell architecture places electrical contacts on the back of the cell, allowing more sunlight to be converted into usable power while reducing shading losses.
With a powerful 550W output and high-voltage design (80V Vmp), this panel is ideal for larger battery charging systems and MPPT charge controller installations. Its rugged rigid construction and durable aluminum frame make it well-suited for marine, van, and off-grid applications where dependable power generation is critical.
Perfect for high-demand installations, the 550W Rigid Solar Panel delivers exceptional watts per panel, helping maximize energy production while reducing the number of panels required. Whether you're powering a cruising yacht, remote cabin, expedition vehicle, or commercial solar system, this panel provides industry-leading efficiency and outstanding real-world performance.
Due to the size of this panel, shipping is not free. A $100 shipping credit is applied, you only pay the remaining shipping cost at checkout.

Why Choose HPBC Technology?
Traditional solar cells place conductive busbars on the front surface, partially blocking sunlight. HPBC technology moves electrical contacts to the rear of the cell, allowing more sunlight to reach the active surface. The result is:
- Higher efficiency
- Improved low-light performance
- Better aesthetics
- Reduced power loss
- Increased energy yield over the life of the panel
Ideal for High-Performance Solar Systems
With an operating voltage of 80V and open-circuit voltage of 96V, the 550W Rigid Solar Panel is particularly well-suited for:
- MPPT charge controller systems
- High-voltage solar arrays
- Large battery banks
- Energy-intensive off-grid installations
Its combination of high efficiency and high voltage can help reduce wiring losses and optimize overall system performance.
Frequently Asked Questions
Is this panel suitable for marine installations?
Yes. The 550W Rigid Solar Panel is an excellent choice for boats and yachts where maximizing power production is important. Verify mounting hardware and installation methods are appropriate for your vessel and environment.
What type of charge controller should I use?
Due to the panel's high operating voltage (80V Vmp, 96V Voc), an MPPT charge controller is strongly recommended for optimal performance and energy harvest.
Can multiple panels be connected together?
Yes. Panels can be wired in series or parallel depending on your system voltage requirements and the specifications of your charge controller or inverter.
Does the panel perform well in hot weather?
Yes. The panel features an excellent temperature coefficient of -0.24%/°C, helping reduce power loss during high-temperature operation compared to many conventional solar panels.
Can this panel charge a 12V, 24V, or 48V battery bank?
Yes. When paired with a properly sized MPPT charge controller, the panel can be used with 12V, 24V, or 48V battery systems.
What are the dimensions of the panel?
The panel measures 84.65" × 44.65" × 1.18" (2150 × 1134 × 30 mm). Be sure to verify available mounting space before ordering.
