Because manufacturer rankings are based on the total volume of solar panels that the companies ship, being in the top position does not necessarily mean they offer the highest quality panel. Some of the smaller manufacturers specialize in premium products, whereas most of the larger manufacturers have gotten to where they are by either making a panel for the high volume market or by focusing their efforts on large-scale projects.
