Calculate Sun Hours Per Day
Several factors influence how much sun power your solar panels will be exposed to, including:
When you will be using your system: summer, winter, or year-round.
Typical local weather conditions
Fixed mounting vs. trackers
Location and angle of PV array

Check out our handy chart that rates daily sun hours available for generating electricity. The effectiveness of your solar array depends on how directly the sun’s rays hit the panels—optimal performance happens when the rays strike at the best angles.
For summer-centric usage, refer to the summer sun hours; for year-round or critical applications, lean towards the winter values. By using the chart, you can gauge the sun’s availability in your area and make informed decisions about your solar setup.
