Certified figures by basic model
Sorted by size, smallest first, then by UEF, highest first.
Size is the size the model is sold as. UEF is the uniform energy factor. A UEF compares only between models with the same draw pattern. A range means the models under one basic model differ. A dash means no such figure.
Of these, 470 basic models may qualify for at least one rebate program. See rebates by state
