What is solar panel wattage?
Also known as a solar panel's power rating, panel wattage is the electricity output of a specific solar panel under ideal conditions. Wattage is measured in watts (W), and most solar panels fall in the 400+ W of power range. We'll use 450-watt panels in these calculations.
How many solar panels do I Need?
Your needs may be different depending on your sunlight and energy needs. ~ 8,000 to 10,000W of solar panels can usually meet the average US home energy consumption. Using large 400W solar panels, this is equal to 20 to 25 solar panels. Larger homes, ones in stormy regions, or those with high energy consumption might need more, going up to ~30,000W.
