Solar tracking systems are used to continually orient photovoltaic panels towards the sun and can help maximize your investment in your PV system. They are beneficial as the sun’s position in the sky will change gradually over the course of a day and over the seasons throughout the year. Advantages to using a tracker system like this will depend mainly on it’s placement in determining how well it will increase the effectiveness of the panels. They can be used most effectively in areas with low horizons and locations that are shade free from dawn to dusk each day. Throughout the year the tracking array will be able to utilize the wide open access to gain every available electron from the sun. This way, energy production is at an optimum and energy output is increased year round. This is especially significant through out the summer months with its long days of sunlight available to capture and when, at many Northern latitudes, the sun rises in the northeast and sets in the northwest, no energy will be lost. For those with limited space this means that a smaller array only needs to be installed, a huge advantage for those smaller sites with only a small area to place equipment; they will be able to produce maximum energy output but only need to utilize one of the smaller solar home systems.
