Red Dog Mine Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Red Dog Mine, Alaska
Fixed Tilt Sunlight Hours: 2.5 hours per day
1-Axis Tilt Sunlight Hours: 3.5 hours per day
2-Axis Tilt Sunlight Hours: 3.7 hours per day
The average peak sun hours of Red Dog Mine is a crucial measurable component needed to efficiently implement a solar power system in a home or business. Put simply, peak sun hours are the hours of sunlight a day that are strong enough to be efficiently absorbed by solar panels and eventually turned into usable electricity. Not every minute of sunlight during a day is strong enough to be useful to a solar power system. Think about just minutes after the sunrises, which officially counts towards total hours of sunlight, but is usually too weak to be counted in peak sun hours because the strength of the solar insolation is not strong enough near the horizon to be absorbed and turned into electricity at an efficient rate. Times during the day like this, where the sun is out but not strong enough, are not counted as peak sun hours. In other words, the amount of peak sun hours in a location will theoretically always be less than total sunlight hours for a given day.
Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Red Dog Mine is 68.1. Knowing the latitude of Red Dog Mine 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.
There are a few ways to increase average peak sun hours per year for your solar power system. One way is to use a tracking mount solar panel instead of a fixed tilt solar panel. A 1-axis mount will track the sun throughout the sky from sunrise to sunset, giving your panel a more efficient facing direction towards the sun throughout the day. A 2-axis solar panel will track the sun in the sky throughout the day, but also change and follow the angle of the sun in the sky throughout the year. Both of these axis system solar panels will produce higher average peak sun hours than a fixed solar panel.
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.
By taking the latitude of Red Dog Mine 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 Red Dog Mine one can expect close to 2.5 average peak sun hours per day. With a 1-axis tracking mount you would get 3.5 hours per day, and 3.7 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
