Sunpower produces the most efficient solar panels in the world.
Overview

SunPower is the producer of the most efficient solar panels on the planet, producing solar panels that achieve a efficiency of 19.3%. Currently they offer 5 different models of solar panels to meet the needs of both residential and commerical customers. These models are the 210, 215, 225, 230, and 315 which operate at efficiencies of respectively, 16.9%, 17.3%, 18.1%, 18.5%, and 19.3%. As you probably could have guessed, panels of this high of quality come with a high price tag as well; Sunpower panels are some of the more expensive panels money can buy (see section below for complete pricing information). And even if you do have the money to purchase Sunpower panels, not just any dealer sells the panels. Sunpower maintains exclusive control over who carries their products, and tends to allow only the most qualified of dealers to sell and install their products (see our installer listing to find installers who carry Sunpower panels). However, if you do manage to get Sunpower panels, the consensus among customers seems to remain the same: that of complete satisfaction. No other company has yet to produce a panel that can outperform Sunpower solar panels.
