Peak sun hours are a vital measurement to understand when considering the installation of solar panels. Peak sun hours are not the same as total sunlight hours because not every hour of sunlight during the day has enough strength and solar insolation to qualify as a peak sun hour. The rule of thumb is that a peak sun hour is when the intensity of the sun that is hitting your solar panel is providing at least 1,000 watts per square meter. This is an arbitrary number, but it is a number where most solar panels will be producing an efficient output and not underperforming due to sunshine that is not strong enough or direct enough.

Sunlight hits the earth directly at the equator. This is why the equator has a latitude of zero degrees. The latitude of Garwood is 29.4. Knowing the latitude of Garwood 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.

Throughout the day the sun obviously moves throughout the Garwood 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

Peak sun hours are greatly affected by weather patterns. Cloud coverage is a huge factor in peak sun hours per day because heavy cloud coverage will diminish the power of the solar insolation. You can use historical climate data to estimate average cloud and weather coverage, but it will obviously vary slightly from year to year.

Since we know the latitude of Garwood we can take the average amount of total sunlight hours and estimate that with a fixed solar panel there would be an average of 4.6 peak sun hours per day. 7.2 hours per day with a 1-axis tracking mount that tracks the sun from sunrise to sunset, and 7.9 hours with a 2-axis tracking mount that tracks the sun everywhere in the sky.
