Sunlight

Fixed Tilt Sunlight Hours: 6.3 hours per day

1-Axis Tilt Sunlight Hours: 6.5 hours per day

2-Axis Tilt Sunlight Hours: 7.2 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 Johnstown is valuable for calculating your solar needs.

Knowing that the latitude of Johnstown is 43.1 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 Johnstown 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.

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.

By taking the latitude of Johnstown 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 Johnstown one can expect close to 6.3 average peak sun hours per day. With a 1-axis tracking mount you would get 6.5 hours per day, and 7.2 hours per day with a 2-axis tracking mount that tracks the sun everywhere in the sky.
