How This Calculator Works
This tool provides a two-part estimation for planning a solar panel installation. First, it calculates the required size of your solar array (in kilowatts) based on your annual electricity consumption, local solar conditions, and how much of your bill you want to offset. Then, it estimates the number of panels and the roof area needed based on the size of the array and the specifications of the panels you plan to use.
Environmental Factor: This accounts for real-world inefficiencies like dust, shading, and equipment degradation. A value of 85% is a common starting point.
