Solar energy tracking is a smart and efficient way to maximize the amount of electricity generated from solar panels. Unlike fixed solar panels, solar trackers allow the panels to follow the sun’s movement across the sky. This ensures that the panels are always positioned to capture the maximum amount of sunlight. But how does solar energy tracking work, and is it worth the investment? Let’s break it down into simple terms that anyone can understand.
What Is Solar Energy Tracking?
Solar energy tracking is a system used to adjust the position of solar panels so they can follow the sun’s path throughout the day. The main idea is simple: more direct sunlight equals more energy. A fixed solar panel stays in one position all day, but a solar tracker moves the panel to face the sun as it changes its position. This allows the solar panels to capture sunlight from dawn to dusk, boosting energy production significantly.
Types of Solar Trackers
There are two main types of solar trackers: single-axis and dual-axis.
- Single-Axis Trackers: These trackers move the solar panels on one axis, typically from east to west. They follow the sun’s horizontal movement across the sky. These are simpler and more affordable than dual-axis trackers but still offer a significant increase in energy production compared to stationary panels.
- Dual-Axis Trackers: These trackers move on two axes, allowing them to track both the horizontal and vertical movement of the sun. This makes them more efficient, especially during seasons when the sun is lower in the sky, but they are also more expensive to install and maintain.
How Much Energy Can Solar Tracking Save?
You might be wondering, “How much more energy can I really get by using solar tracking?” The answer depends on several factors, such as your location, climate, and the type of solar tracker you use. On average, single-axis trackers can increase energy production by 20-30%, while dual-axis trackers can boost it by up to 40%.
For example, if you live in a sunny state like Arizona or California, the benefits of solar tracking are even greater because you have more hours of direct sunlight. In contrast, regions with cloudy climates may not see as significant an increase in energy production, but solar tracking can still help capture more energy during peak sunlight hours.
The Costs and Benefits of Solar Energy Tracking
One of the main concerns people have about solar tracking is the cost. Solar trackers are more expensive than fixed solar panels, both in terms of initial installation and ongoing maintenance. Dual-axis trackers, in particular, are more costly due to their complexity.
However, the long-term benefits often outweigh the upfront costs. By increasing the amount of electricity your system generates, solar tracking can help you save more money on your energy bills. Over time, the extra energy production can offset the higher installation costs, especially in areas with high electricity rates or generous solar incentives.
From my own experience, I’ve seen how solar tracking systems can make a noticeable difference in energy savings. A friend of mine installed a single-axis tracker on their rooftop in Nevada. Over the course of a year, they noticed a 25% increase in energy production compared to their previous fixed system. Although the initial investment was higher, they were able to recover those costs within a few years, thanks to lower energy bills.
Is Solar Tracking Right for You?
Deciding whether or not to invest in solar tracking depends on your specific needs and location. If you live in an area with long, sunny days, such as Arizona or Nevada, solar tracking can be an excellent way to maximize your energy production. On the other hand, if you live in a region with frequent overcast skies, you may not see the same level of benefit.
Additionally, solar tracking systems require more space than fixed solar panels, so they may not be ideal for small rooftops or limited ground space. They also require regular maintenance to ensure that the moving parts are working correctly.

How Does Solar Tracking Impact the Environment?
One of the most significant benefits of solar tracking is its potential to reduce our reliance on fossil fuels. By capturing more solar energy, these systems help reduce the need for energy generated from coal, oil, and natural gas. This, in turn, lowers greenhouse gas emissions and helps combat climate change.
The U.S. Department of Energy (energy.gov) notes that solar energy systems with tracking capabilities can play a key role in reducing our carbon footprint. In fact, by improving the efficiency of solar installations, solar tracking systems can help us transition to a cleaner, more sustainable energy future faster.
Solar Energy Tracking for Commercial Use
Solar tracking is not just for homeowners—it’s also popular for large-scale commercial solar installations. Many businesses and utility companies use solar trackers to optimize their energy production. In areas with a lot of land, such as solar farms, dual-axis trackers are especially useful because they maximize energy production without needing additional space for more panels.
According to the National Renewable Energy Laboratory (NREL), solar farms with tracking systems can produce up to 40% more energy compared to those with fixed panels. This makes solar tracking an attractive option for businesses that want to reduce their energy costs and carbon emissions.
Maintenance and Care for Solar Trackers
One thing to keep in mind is that solar tracking systems require regular maintenance. The moving parts of the tracker can wear down over time, and it’s important to check for any issues, such as misalignment or mechanical failure.
Regular cleaning is also essential, especially in dusty or snowy regions. Dust, debris, or snow can accumulate on the panels and block sunlight, reducing their efficiency. By keeping your system clean and well-maintained, you can ensure that it operates at peak performance year-round.
