350W Solar Panel High-Output PV Module for Arrays

Three hundred and fifty watts per module belongs to the larger end of the range, where the array is being sized in kilowatts and the labour of mounting fewer, bigger panels is worth having. Schools, clinics, farms and commercial buildings are the usual homes for a panel like this.

Wire it into series strings feeding a hybrid inverter or MPPT charge controller, keeping the string's open-circuit voltage inside whatever the controller allows. Use proper rails or a ground frame, allow air behind the module, and keep the whole array free of shade, since one shaded panel limits the string it sits in.
