Your starting point matters
Usage history, current rates, fixed charges and utility billing rules create the baseline. Different bills or periods can produce different comparisons.
System and payment assumptions
Estimated generation, system price, loan fees, lease escalator, battery settings and export credits can materially change a projection.
Ask for transparency
Request a plain-language explanation of assumptions and a comparison showing what utility charges remain. Ask how results would change under different scenarios.
