To calculate how many panels you can fit on your roof, start by determining the total area of your rooftop that’s suitable for solar installation. Subtract any areas that are not usable due to obstructions like chimneys, vents, or shaded regions. With the usable space in mind, consider the size of the solar panels you are interested in.
A typical 20-panel system needs 340-400 square feet of unshaded roof area. Orientation: South-facing roofs provide maximum energy production Tilt: 30-45 degree angles optimize solar collection Shading: Minimal obstruction from trees, chimneys, or neighboring buildings Age: Roofs should have 10+ years of remaining life before panel installation
Our solar panel calculator helps you determine how many solar panels can be installed on your roof and how much electricity they can generate. It calculates the maximum number of panels that fit on the available roof surface, taking into account important factors such as orientation, inclination, and panel type.
The goal for any solar project should be 100% electricity offset and maximum savings — not necessarily to cram as many panels on a roof as possible. So, the number of panels you need to power a house varies based on three main factors: In this article, we’ll show you how to manually calculate how many panels you’ll need to power your home.
