The solar map below shows the photovoltaic solar resource of the United States using monthly averages by state for daily total solar resource information on grid cells. The insolation values represent the level of energy absorption available from the sun (in kWh) to a collection device such as a photovoltaic (PV) solar panel oriented due south. This is typical orientation for PV solar energy system installations. Southern states like Georgia, North Carolina, and Florida all average 5 kWh per day. Northeastern states like New York, Vermont, and Maine all average 4 kWh per day. Southwestern states such as New Mexico, Arizona, and parts of California all average up to 6.8 kWh per day.
