Tracking the Sun: Trackers for Solar Power SystemsRenewable energy is becoming an increasingly important solution to sustainably power our modern world. Among the many renewable energy sources available, solar power has proven to be the most accessible and effective in many parts of the world. However, maximizing solar energy capture requires more than just installing photovoltaic (PV) panels. To really capture the maximum amount of energy, solar panels need to be aligned towards the sun throughout the day. This is where solar trackers come in.A solar tracker is a device that orients a PV system to always face the sun. This increases the panel’s exposure to direct sunlight and therefore improves the production of electricity. A solar tracker system typically involves a sensor, a motor, and a control unit which together maintain the orientation of the panels. The sensor, usually a photodiode, measures the intensity of sunlight and sends signals to the control unit. The control unit then sends signals to the motor to make the appropriate adjustments.One major type of solar tracker is a single-axis tracker. As the name suggests, it has only one axis of movement, allowing it to rotate the panels around one axis from east to west. This type of tracker is the most common and widely used among solar PV systems since it provides the most cost-effective solutions.In addition to the single-axis tracker, there is the dual-axis tracker, which tracks the sun in two axes, allowing it to follow the sun’s seasonal elevation and apparent motion in the sky. This allows the panels to capture the maximum amount of sunlight throughout the year. However, the dual-axis tracker is more expensive and is typically reserved for high-concentration photovoltaic (HCPV) systems.Solar trackers have been shown to increase energy production by up to 50% compared to fixed panels. Moreover, they can help to reduce the cost of electricity generated from PV systems since they can reduce the number of panels needed to achieve the same production levels.A leading company in solar tracking solutions is (need remove brand name). Their unique single-axis tracker system has a reliable, low-maintenance, and cost-effective design. It has been used in numerous solar projects worldwide to increase energy production and decrease the cost of produced electricity.With the increasing demand for renewable energy, solar trackers are rapidly gaining popularity. Hence, there is a need for high-quality solar tracking solutions to ensure maximum energy production in solar systems. Solar trackers are especially vital in regions with low long-term solar irradiance due to geographical factors such as latitude and weather like clouds. In comparison, regions with high long-term solar irradiance can sometimes opt for fixed panels since solar trackers won’t result in significant additional energy production compared to the additional cost of the system.While solar trackers help improve energy production, it is crucial to choose the right type of tracker based on the purpose, location, and intended use of the solar system. There are several factors to consider when selecting a solar tracker, such as installation methods, reliability, maintenance costs, and the environmental conditions the tracker will face.In conclusion, solar trackers are a critical technology that plays a significant role in harnessing solar energy. With the advancement in sensor and control technologies, the cost of solar tracking systems is decreasing, making them more accessible to businesses and individuals alike. In comparison, the energy production increase is considerable, making solar trackers a valuable investment in the long run. Hence, as the need for clean, sustainable energy increases, the demand for solar trackers is expected to rise as well.
