Harrold Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Harrold, Texas
Fixed Tilt Sunlight Hours: 5.1 hours per day
1-Axis Tilt Sunlight Hours: 6.9 hours per day
2-Axis Tilt Sunlight Hours: 7.8 hours per day
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 less than peak sun hours. Looking at the average peak sun hours in Harrold 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 Harrold is 34.1. Knowing the latitude of Harrold 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.
A tracking mount will increase the average peak sun hours for a solar power system. Think about a panel that is tracking the sun in the sky vs a panel that is fixed and not moving: you will see a higher efficiency ratio of productions. A 1-axis mount will track the sun from East to West from sunrise to sunset and move on a single axis of rotation. A 2-axis mount will track the Sun from East to West the same as a 1-axis mount would, but it will also track the angle of the sun in the sky as it slowly varies season to season. A 2-axis mount is more necessary in high latitude regions where the angle of the sun in the sky changes dramatically between each equinox.
Weather is a big determinate of average peak sun hours each day. There are many aspects of weather that can increase or lessen the peak sun hours in a day in a particular location. For example cloud coverage is a crucial variable. And more importantly, what type of cloud coverage; thin scattered clouds will have less diminishing power on the solar insolation than thick rainy storm clouds. Sometimes long periods of sunny days are rare in certain locations, this would increase average peak sun hours for that time-frame
By taking the latitude of Harrold one can get a close estimate of the amount of average peak sun hours per day for the geographical area. It varies with technology and the type of solar panel mount you use, but for a fixed mount solar panel in Harrold one can expect close to 5.1 average peak sun hours per day. With a 1-axis tracking mount you would get 6.9 hours per day, and 7.8 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
