As of 2020 a typical solar panel produces around 320 watts of power but panels come in many different wattage ratings and finding one that produces exactly 320 watts is rare.
250wp dc in controlled conditions.
For any given energy production target you need fewer panels if their individual wattage is higher.
When roof size is limited efficient panels with a high wattage can make the system more compact.
The amount of electricity produced by a solar panel depends on the size of the panel the amount of sunlight the panel gets and the efficiency of the solar cells inside the panel.
Simply put once you know how much power each panel puts out simply divide it by the square feet of the panel.
