I think this will help. Basically, you control the rated wattage by surface area and cell efficiency. Most panel power ratings are given at STC conditions with 1000 $W/m^{2}$ . So as an example, if you specify a 100 $m^{2}$ system with 15% cell efficiency, that corresponds roughly to a 15 kW system.
