450W-550W Solar Panels: The Mainstream Commercial Class
450-550W is the mainstream commercial and large-residential module class: enough wattage to cut labor per kW, small enough to handle with two installers and standard rail spacing. This page lists the modules we stock in that band.
What to check before ordering
- Module length and weight against rail spacing and the lift plan
- System voltage - 1500V modules need 1500V-rated string components
- Isc against per-MPPT current limit; Voc at record low temperature
- Pallet quantity, freight class and jobsite unloading equipment
