The average amount of peak sun hours in a day is a different and more useful number as it relates to solar panels than total sun hours. Total sun hours are exactly what you would expect; the total amount of hours that the sun is out during a 24 hour period. Peak sun hours, on the other hand, are the total number of hours in a day where the sunshine is strong enough to to be absorbed and used by solar panels. Sunlight early in the morning or late at night is often not strong enough to count toward peak sun hours. Because of this, total sun hours will always be more than peak sun hours. Looking at the average peak sun hours in Oakland throughout the year can help you better estimate the amount of solar panels you will need to power your business or home.

Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Oakland is 43.4. Knowing the latitude of Oakland can help you plan for your solar panel setup, as the larger the latitude the more variance you will see throughout the year for total daily sunlight hours.

The sun moves through the sky during the day, and changes positions in the sky throughout the year as the seasons change. A fixed solar panel remains fixed in position during this movement. So, although it is effective in capturing sunlight, a 1-axis or 2-axis panel can be more efficient. A 1-axis panel tracks the sun's movement throughout the day from sunrise to sunset. In addition to that, the 2-axis panel also accounts for the movement throughout the year.

The sunrise and sunset is very predictable every day, but things like cloud coverage and weather are less predictable and vary daily and annually. If a location that is usually very sunny experiences a huge increase in storms and cloud coverage in a given year than the average peak sun hours for that day or year will probably decrease. Tall objects such as trees and buildings can block out the sun during high solar insolation times, so be sure to strategically place your solar panels to get better efficiency.

In Oakland you can look at the average peak sun hours of a fixed solar panel mount, which will be 4.4 hours. This number iis an estimate based on data of previous years. With a tracking mount in Oakland you could theoretically increase the amount of peak sun hours per with a 1-axis mount, and get 5.5 hours, or a 2-axis mount and potentially increase your average to 6.7 hours.
