Looking at the average peak sunlight hours in Provincetown is a valuable number for determining your solar power setup. Peak sunlight hours are only the hours a day in which the sunlight is strong enough for the solar panels to do their job. Not every hour of sunlight was created equal. For example, solar panels do not provide much use during early sunrise and sunset, and therefore you should not look at total hours of sunlight in a day, but instead focus on peak sunlight hours. Using this number will provide a much better estimate of your needs for setting up panels in Provincetown, Massachusetts.

Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Provincetown is 42.1. Knowing the latitude of Provincetown 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.

There are more variables than latitude that can change average peak sun hours. Weather patterns and geography will influence solar insolation that reaches your system. Thick grey storm clouds for example will block out a lot of the sun to the point where there may be no peak sun hours in the middle of the day when the sun is usually very powerful. Trees and mountains can deflect the sunlight, so be sure your solar panel is selectively placed.

We can use previous years of data to estimate the amount of peak sun hours in Provincetown. A fixed tilt mount for example will receive 4.2 average hours per day. For more efficiency for your system in Provincetown you could use a 1-axis tracking mount and increase your daily peak sun average to 5.4 hours, or even further with a 2-axis panel to get an average of 6.3 hours.
