You will find the default $2400 annual bill amount as a placeholder. Entering actual data as an annual input will change the corresponding monthly values based on the selected load profile. You can also input the monthly values, bringing change to the corresponding annual consumption number. In both above cases the hourly consumption is used in calculations ahead and they will be generated based on the selected load profile.
Once you have entered in the data, click on "Change" to see the load profile in different formats based on your hourly consumption.
