Anvik Solar Power Information & Peak Sun Hours
Solar Green Energy Summary for Anvik, Alaska
Fixed Tilt Sunlight Hours: 3.1 hours per day
1-Axis Tilt Sunlight Hours: 4.6 hours per day
2-Axis Tilt Sunlight Hours: 4.9 hours per day
When trying to calculate your solar power needs there are a variety of factors to consider. Panel type and location, electricity needs, number of panels needed etc. One key to figuring out the math is factoring in the average peak sunlight hours in a day. Unlike total sunlight hours, peak sunlight hours are only when the sun is strong enough to power your solar panel. Using this number can help determine your needs to power your home or business in Anvik, Alaska.
Knowing the latitude of Anvik will help estimate average peak sun hours for your area. The latitude is used to accurately estimate the time of sunrise and sunset, thus giving you the total hours of daylight each day. Once you know the total hours of daylight, you can estimate the amount of peak sun hours based on a number of variables such as weather, time of year, the angle of the solar panel.
They type of solar panel you use has an affect on the average peak sunlight hours. Some panels allow for movement, so they can track the sun as it rises in the east and sets in the west, or as the seasons change and the sun's path changes. A fixed panel remains fixed and does not have the ability to rotate, whereas a 1-axis and 2-axis panel can adjust with the sun.
Another reason to consider average peak sun hours is because weather can dramatically affect the day-to-day output of solar panels. It goes without saying that a dark stormy day will produce less output than a clear sunny day. Looking at a yearly average helps account for these daily variables.
In Anvik the average yearly peak sun hours for a fixed tilt non-tracking solar panel mount is 3.1. This is for a fixed panel mounted at an angle that is equal to the latitude of the location for the entire year. The amount of peak sun hours increases to 4.6 hours if you are using a 1-axis panel, and to 4.9 hours if you upgrade to a 2-axis solar panel.

Do solar panels need to be replaced?
Even more than just the panel equipment themselves, inverters will impact how long your panels can last depending on which type you buy. A typical central inverter for a PV installation will last between 10 and 15 years and thus will need to be replaced at some point during the lifetime of your solar panels.
