Different panels will have different watt ratings so you have choices about which ones to purchase. Assuming you are going to choose standard efficiency solar panels here are the most common sizes for residential solar systems and their kwh production potential to give you an idea of how many panels you would need to run a house. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average.

The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size. Home will need between 33 and 26 solar panels of 250 watts.
