The Alexus Solar ALEX-550-W-144-S is a 550-watt monocrystalline solar module in a 144-half-cell format, built for commercial and high-output residential arrays where monocrystalline efficiency and per-panel wattage drive the design. The 144 half-cell layout splits conventional cells to reduce resistive losses and improve shade behavior at the string level — a meaningful advantage on real rooftops with vents, trees, and parapet shadows.
At 550 W, the module reduces panel count on commercial rooftops and ground mounts while remaining within the handling envelope of experienced crews. It fits standard large-format racking and pairs with mainstream commercial string inverters, making it a versatile procurement choice for installers serving both residential and commercial segments.
Key Features
- 550 W monocrystalline module
- 144 half-cell format
