Traditionally after the solar panels were first invented, solar collectors remained in one position. This was selected with consideration to the direction of the sun light and it was where the sun will hit the most. When things seemed not to work for more electricity, solar panels were then used in doubles so that when one faced the east, the other was facing the west. Sunlight from both directions whether during the morning or during the evening could be trapped. With consideration on cost and space, things still never seemed not to work. This has been the trend until the invention of the solar trackers. They are able to make the solar collectors rotate relevantly to face the sun directly at any particular moment. Incredible indeed! You have all the reasons to install such a system.
- More electricity In hydro electricity generation, the more the water force, the more the megawatts generated. For our case here, the sun is the focus. The more the intensity, the more the electricity output. When the solar collectors are placed at a stationary position, the electricity generation is reduced. Energy losses will be experienced during some times of the day. If the collector is placed to face the east, it means that during the evenings, it will be trapping much reduced direct sunlight. When you add a tracker though, the solar is placed at a position direct to the sunlight thought the entire day. Whether in the morning, noon or the evening, the collector will be getting quality light directly from the sun. That in other words means more electricity generation due to enhanced efficiency. It will also help you in reducing power bill.
- Save on space These days, space is becoming limited. People don’t have huge tracks of land to fill with stationary solar panels as it was the case some time ago. What is left is to make the best use of the small land. With trackers now available, the need for huge land is reduced. The collectors will still be collecting their maximum light even when rotating on their own axis. The electricity generated by tracker-installed solar collectors is equal to that generated by stationary collectors. Using the stationary models is hence seen as a wastage of land.
- Freedom of choice
People have different needs with regard to the many disparities that surround them. The location is a very important factor when installing solar collectors. Solar Tracking is however availed in many types for suitability to every single buyer. Other considerations include, local weather, electrical requirements, installation size, degree of latitude etc. Two general types of trackers are in the market. The single-axis and the dual-axis trackers are the names given to these products. With the right considerations, you can be able to select the best tracker with high efficiency.
