What Does 20% Efficiency Mean for Solar Panels?

When you hear about a solar panel with 20% efficiency, it refers to the panel’s ability to convert 20% of sunlight into usable electricity. This means that for every 100 watts of solar energy hitting the panel, 20 watts will be transformed into power for your home. A 20% efficient solar panel represents the current industry standard for residential installations, offering a balance between performance and cost.
