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 Pender, Virginia.
The latitude at the equator of the earth is zero degrees. This is where sunlight strikes the earth most directly. Due to the earth's curved shape, sunlight hits at a various angles depending on location. As latitude increases, the further you are located from the equator and more variance you see in sunlight hours. The latitude of Pender is 38.9.
Throughout the day the sun obviously moves throughout the Pender sky. The suns position in the sky also changes throughout the year with the seasons. A fixed solar panel does not accommodate for these changes. However, a 1-axis panel rotates and follows the sun’s path during the day. A 2-axis panel both follows the sun’s daily path as well as the seasonal differences
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
We can use previous years of data to estimate the amount of peak sun hours in Pender. A fixed tilt mount for example will receive 4.7 average hours per day. For more efficiency for your system in Pender you could use a 1-axis tracking mount and increase your daily peak sun average to 5.8 hours, or even further with a 2-axis panel to get an average of 6 hours.
