Solar panels are strategically positioned to facilitate direct exposure to the sun at midday and may face north or south, depending on the hemisphere. The acute angles at which the morning and evening sun are directed at the solar panels limit the amount of power that is produced on a daily basis.
Solar panels are fitted onto devices known as solar trackers that are designed to track how the sun moves across the sky. This ensures that the amount of sunlight hitting the panels is maximized all day long.
Solar trackers are cost effective and highly efficient devices that significantly increase the amounts of electricity generated. Panels need to be installed in a way that enables the rays of the sun to strike them at perpendicular or incidence angles. Using a solar tracker drastically increases the output of the system. System output increases at a higher rate during summer and slightly less during the colder seasons.
Types of Solar Trackers
• Solar trackers are categorized as single or dual axis. Single trackers typically rotate from east to west, as they follow the option of the sun while dual axis trackers move upwards or downwards to cater for the sun’s angles during summer and winter.
• A single axis solar tracker features one angle that is used as the rotation axis. This type of tracker has the ability to increase the production of electricity by more than 30%. It provides a simple, affordable and efficient way of enhancing the performance of solar installations.
• Dual trackers feature two degrees of rotation axis that are known as the primary and secondary axis. They also provide additional increase in energy output. Engineers can adjust the angles and designs of both types of trackers.
Benefits of Using Solar Trackers
Including a solar tracker on a solar installation determines not only whether energy will be produced but also the actual production of adequate energy as well. Mechanized solar trackers can be used for both residential and commercial installations. They work by increasing the amount of sunlight exposure that reaches the solar panels.
• Solar trackers are worthwhile investments that are included on various systems to harvest extra sunshine and take full advantage of sun tracking technology.
• A major advantage of using solar trackers is the total increase on output performance. The level of performance is determined by factors such as engineering and the type of tracking system that is used.
• A dependable tracking system is essential and should efficiently track the actual sun and not its reflection, which results in false rotation throughout the day. Adequate sun exposure is required because an abundance of clouds will inhibit the performance of a tracking system. It is also important to place the tracker in a location that provides maximum sun exposure and low horizons.
• Solar trackers have proven to be valuable additions to applicable commercial installations. They continue to be a popular option among photovoltaic plants owing to their extensive benefits within the solar industry. They allow significant increases in energy generation and help to boost the profitability of projects.
