    Here is some information about the tool

    This tool simplifies the complexity of the solar purchase decision by making intelligent assumptions, automating the rooftop analysis and providing recommendations to get you started. The tool strives for objectivity and reasonable accuracy.

    However, there are factors that may alter results, including specific equipment attributes, complex installation scenarios, unaccounted for shading and roof obstructions, credit worthiness, specific tax situations, aesthetic preferences, and potential changes to SMUD rates.

    The charts, graphs and analysis provided by this solar analysis tool are for illustrative purposes only and do not constitute a representation by SMUD as to whether or not you should install solar.
