ROI Calculator Assumptions:
In an effort to make this calculator as simple and straight forward as possible several assumptions were made relative to the energy sources used to provide water to the irrigation system, along with crop yield data. This helps to form a logical impression of overall energy costs, without the need for labor intensive calculations or time consuming fact finding endeavors.
Diesel Generator Sets - An average fuel consumption of 16 hp/hr/gal was used to simplify power requirement calculations. This is an industry average number obtained from research performed on several different engine and pump sets of different makes, model, configuration and horsepower. Actual fuel consumption may vary.
Electric - An average of 1.18 hp/hr/kw was used to simplify power requirement calculations. This is an industry average number obtained from research performed on several power source, pump and electric motor configurations. Actual electric power consumption may vary.
Incremental annual yield increases for the specific crops listed was obtained from annual USDA crop production reports, published from 2001 – 2011.
