When considering municipal on-site solar PV, it is important to first understand your portfolio-wide solar energy generation potential. This not only helps you understand the potential impact of your project on reaching your broader renewable energy goals, but also identifies the municipal sites with the greatest solar energy potential.
First, list all municipal buildings, parking lots, and lands (e.g., land near water treatment plants, airports) connected to an electric meter using an organized template such as the Environmental Protection Agency’s (EPA’s) Solar Site Assessment and Utility Data spreadsheet
Organizing Site Assessments:
EPA’s Solar Site Assessment and Utility Data spreadsheet is a template designed to help users collect information about potential solar project sites. . Column letters from this spreadsheet are referenced on this section of this website. After inputting the site type and address into columns E and F, you can then use the Draw Your System function (under the System Info tab) of the National Renewable Energy Laboratory’s (NREL’s) PVWatts tool to determine the following information to help prioritize sites:
