Table of Contents

400W solar panels are higher than the average power of solar panels available today and can be a reliable panel choice for many types of solar projects.

To decide if a 400W solar panel is right for you, it’s important to understand what options are and how much energy a 400W panel produces.

What is a 400W solar panel?

A single 400W solar panel produces 400W of electrical output that can be used in commercial and residential solar projects. A 400W solar panel will generate around 1.2 and 3 kilowatt-hours (kWh) per day, depending of course on their exposure to sunlight and other factors including geographic location and inclination.
