    Here is some information about the tool

    This tool simplifies the complexity of the solar purchase decision for PV by making default assumptions regarding your rooftop 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 existing residential electric rates.

    Results provide a baseline for sizing systems. If solar seems like a good investment for you, please be sure to review existing programs available and consult with a solar contractor. It is recommended that the actual system sizing consider roof space, alignment and shading in discussions with your solar installer. Actual site requirements will determine sizing.

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