How many solar panels do you need to install?
There’s no one-size-fits-all answer. The right number of solar panels depends on your home and how much electricity you use.
Your installer will consider factors such as your annual energy consumption, available roof space, roof orientation, and shading. The power output of the panels also affects how many you’ll need.
A larger system isn’t automatically better. The goal is to design a system that matches your household’s energy needs and makes good use of the space available.
Start with a professional assessment to find the right solar setup for your home.
