Campbell Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Campbell, California
Lattitude: 37.2803
Sunlight
Fixed Tilt Sunlight Hours: 5.3 hours per day
1-Axis Tilt Sunlight Hours: 6.8 hours per day
2-Axis Tilt Sunlight Hours: 8.2 hours per day
The amount of hours from sunrise to sunset is equal to the total sunlight hours in a 24 hour period. Similarly, peak sun hours are the amount of total sunlight hours in a 24 hour period that are strong enough to provide power from being captured by a solar panel. Not every hour of sunlight delivers the same amount of energy resources. The sunlight at sunrise does not provide as many resources as the amount of sunlight mid-day. Thus, looking at the average peak sunlight hours for Campbell is valuable for calculating your solar needs.
Knowing that the latitude of Campbell is 37.3 can be helpful for understanding total sunlight hour variance. As you approach the equator latitude approaches zero. The closer the latitude is to zero, the more consistent the daily sunlight hours are throughout the year. Total sunlight hour consistency simply makes planning for your solar power needs easier, but it is certainly not a requirement.
You will notice that the average peak sun hours for Campbell change based on the type of panel being used. The reason for this is quite simple. A fixed panel does exactly what it sounds like, remains fixed in one position at all times. A 1-axis and 2-axis panels have axis that allow them to rotate. The 1-axis rotates with the sun's daily east to west movement while a 2-axis also adjusts for seasonal changes.
Climate in your geographical region is a major factor that will influence average peak sun hours per year. If you live in a region that does not have a lot of completely sunny days, then cloud coverage will greatly influence solar insolation on any given day. Mountains and trees may also contribute to lower solar insolation if they block the sun from your panels at any given point of the day.
Using the latitude of Campbell along with historical data of sunlight and weather patterns we can estimate that a fixed mounted solar panel will receive an average of 5.3 hours per day in this area. That number can be increased with better technology including add a 1-axis or 2-axis tracking mount, which would increase the average peak sun hours per day to 6.8 hours and 8.2 hours, respectively.

How big is a 1 KW solar panel?
Certain solar panels in market can use as high as 90% of rooftop area, but have much higher cost. As a thumb rule, 10 Sq meter area is required for 1 Kw capacity solar system. As a thumb rule, 1 Kw capacity solar system generates 1600 – 1700 Kwh of electricity per year.
