Solar Green Energy Summary for Yucca, Arizona
Fixed Tilt Sunlight Hours: 6.2 hours per day
1-Axis Tilt Sunlight Hours: 8 hours per day
2-Axis Tilt Sunlight Hours: 8.7 hours per day
Peak sun hours is arguably the most important number to consider before installing your solar panels. Unlike total sun hours, peak sun hours are calculated by looking at the amount of sunlight hours in a 24 hour period that is strong enough to be absorb by a solar panel. One way to imagine peak sun hours is to think about a solar powered calculator you owned in school. If you covered the solar panel with your finger, or tried to use the calculator in the dark, the calculator would not work. As you slowly exposed the calculator to light the calculator would eventually turn on and be usable. The same is true with peak sun hours; these are the hours that your solar panels receive enough sunlight to work. Looking at the average peak sunlight hours of 6.2 per day can help you determine the amount of solar panels you need to install to power your home or business in Yucca, Arizona.
The equator has a latitude of zero while Yucca has a latitude of 34.9. Any city located on the equator will receive the most sunlight throughout the year because the sunlight arrives at a perpendicular 90 degree angle to the earth at the equator. The further you are from the equator the more your daily sunlight hours can vary.
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 sun is a great ball of gas that rises and sets every day that the earth rotates while in orbit around the sun. Barring any major disasters this is a very predictable occurance every day. Latitude helps predict this even more, narrowing it down to the minute for sunrise and sunset. But some things aren’t as predictable that will greatly influence the efficiency of solar panels. Weather and cloud coverage for example can greatly diminish peak sun hours on any given day. Thick storm clouds will block a high percentage of the sun's rays, resulting in lower output of your solar panels. Weather needs to be factored into deciding when to use your system, or how much output one expects to get.
Since we know the latitude of Yucca we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 6.2 peak sun hours per day. 8 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 8.7 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
