The optimal tilt angle for solar panels typically equals your location's latitude. For most of the continental United States, this means angles between 25-45 degrees.

A bracket inclination ruler acts as your "solar compass," ensuring panels face the right direction year-round. Latitude: Panels near the equator typically need 10-15° tilt, while northern regions require 30-45°. Seasonal adjustments: +15° in winter and -15° in summer for temperate.

This scenario would require the installer to select either 17 panels (7. 10 kW), depending on the specific design goals and roof availability.

A simple estimate is panel wattage × number of panels × peak sun hours × system efficiency, then divide by 1,000 to convert watt-hours to kilowatt-hours. What are peak sun hours? Peak sun hours are a simplified way of expressing the amount of solar energy available in a day.
