Follow the link next to “Average Hours of Peak Sunlight per Day” field. Enter your zip code or city state to look up average peak sun hours each month. Alternatively, NREL (National Renewable Energy Lab) provides a free tool called “pvwatts”

” https://pvwatts.nrel.gov/ ” for more specific data in more locations and more detailed information. Be sure to change the “tilt angle” to optimize for winter sun in your area.
