550W Solar Panel Utility-Size PV Module for Arrays

The 550W panel is the largest module in this part of the range and is chosen for projects measured in tens of kilowatts: commercial roofs, ground-mounted farm arrays and institutional installations where mounting labour per watt is what decides the design.

Plan for the weight and area of a module this size before quoting the job. Use engineered rails or frames, respect the manufacturer's clamping zones, and check string open-circuit voltage against the inverter input limit with the coldest morning in mind. Access for cleaning is worth designing in, since dust is what quietly takes the output away.
