Most Efficient Solar Panels
Two great questions many people ask about solar panels are: “Which panels have the highest efficiency?” and, “Which solar PV panels are the best?”
This solar power panel comparison chart (from SRoeCo’s sortable, searchable Solar Panel Comparison Table) compares the output per square foot surface area of most 200 W model solar panels. All of the modules on this chart are label rated at 200 Watts, which means in strict laboratory conditions, they produce the same output. However, I have compared them based on their PTC ratings which is the rating given under realistic test conditions. Sanyo, SunPower, Schuco, Kyocera, Suntech, GE, Evergreen, Canadian Solar, and Sharp are common solar panel manufacturers used by installers in the US.
