Hello. I suspect if you are looking for some calculations for cost savings of solar vs. whatever that you will find and Excel spreadsheet to be the most convenient to use. Probably can be done with just formulas in the cells,but if there is something complex, I can write some VBA code for that. Give me some more details and we will discuss it.
