Caution: Photovoltaic system performance predictions
calculated by PVWatts® include many inherent
assumptions and uncertainties and do not reflect
variations between PV technologies nor sitespecific
characteristics except as r epresented by PVWatts®
inputs. For example, PV modules with better
perfor mance are not differentiated within PVWatts®
from lesser perfor ming modules. Both NREL and
pr ivate companies provide more sophisticated PV
modeling tools (such as the System Advisor Model at
http://sam.nrel.gov) that allow for more pr ecise and
complex modeling of PV systems.

These values can be compared to get an idea of the costeffectiveness of this system. However, system costs, system financing
options (including 3rd party ownership) and complex utility rates can significantly change the relative value of the PV system.
