Dual Axis Solar Panels

Solar energy has existed for millennials. However, it is only at the turn of the 21st century that humankind learned how to harness it effectively. With structures like solar panels, sunlight is easier than ever to power up your space and appliances.

Most solar structures are static, i.e. they need to be installed in a location where maximum sunlight falls. This could pose a limitation, especially on days when clouds restrict sunlight. Fortunately, technological advancement has led to the creation of solar trackers that follow the sun’s position as it moves throughout the day.

A dual-axis solar tracker is a type of solar tracker that can help increase energy for your space by following the sun as it moves. Curious? Read on to find more!10%

Key Takeaways

• Dual-axis solar panels are advanced solar trackers that increase energy efficiency by following the sun’s movement, providing up to 49.83% more power than static panels.
• They offer unmatched flexibility and accuracy in tracking the sun’s position, allowing them ideal for maximising energy output and addressing power capacity limitations.
• Despite their advantages, dual-axis solar panels have complex structures, shorter lifespans, and reduced performance in overcast weather. Still, their market is growing due to government incentives and increasing electricity demand worldwide.

The Principle of Dual Axis Solar Panels

These structures possess a solar sensor, a device used to locate the sun’s position. Alternatively, some dual-axis solar panels rely on GPS to accurately gauge the sun’s location. Upon receiving the sun’s signal, the solar panel moves accordingly and points towards the sun’s direction.

These solar trackers are paired with electric motors or hydraulic rams to ensure complete control. As the sun changes course, the solar tracker follows it to ensure maximum energy for your space.

Hybrid tracking systems are often recognized for their enhanced efficiency compared to other systems. They generate significantly more energy daily, making them popular for harnessing power.

One of the most significant advantages of the dual-axis solar tracking system is that it tracks the angular and east-west position of the sun. Irrespective of the sun’s position, you are guaranteed to receive an appreciable energy output.

Why Choose Dual Axis Solar Panels?

Traditionally, solar panels come in two forms – single-axis and dual-axis.

As the names suggest, single-axis panels can only move through a single plane, most commonly east-west. Dual-axis panels can cover both planes along which the sun can potentially move and are preferred for their north-south orientation.

The clear winner is dual-axis panels.

Single-axis panels are still valuable and a great option on a tight budget. They are also a better alternative to static panels that produce lesser output.

However, an axis solar tracking system is perfect if you have the budget and aim to harness maximum energy for your space. Not only is it more accurate, but it is also more precise and efficient than other solar trackers on the market.

Configurations Available

Sunlight is one of the most important sources of renewable energy. It also found reliable use to harness the power and replace fossil fuels in the long run. Hence, investing in an effective dual-axis solar tracker is crucial.

Here are some configurations for these devices based on changing the position of the tracker:

Manual

Usually done in countries with low labour costs, this method involves dedicated personnel changing their position throughout the day. They are asked to manually direct the panel’s position to the area receiving maximum sunlight.

Passive

These structures utilise the services of a bulb of liquid. The bulb gets heated when sunlight falls on it, and the liquid evaporates. This process expands volume, pushing the solar tracker towards the sun.

Active

Active trackers require electric or hydraulic motors to adjust the tracker’s position. These devices use light-dependent resistors as sensors. If there is a difference in output, it will generate error signals.

Advantages of Dual-Axis Solar Panels

There are multiple reasons, including the government’s initiatives to promote solar energy and subsidiaries. But what makes them so unique from other solar energy-harnessing options?

• They possess an unmatched degree of flexibility, allowing them to change course as per the sun’s position and produce more energy.
• Renewable source of energy with solar arrays trapping sunlight and saving costs
• Low maintenance costs in the long run; the panels require essential maintenance like regular cleaning
• A high degree of accuracy in tracking the direction of the sun
• Follow the sun constantly without losing track, ensuring consistent energy to power up your space throughout the day
• Installation is easy, and the devices do not take up significant space, allowing you to position them in a place where they can work uninterrupted
• The lower payback period on investment
• It is ideal for areas that hinder solar productivity with uneven structures that prevent sunlight from reaching static solar panels effectively

Dual-axis panels can also help address the limited power capacity in your area. They work on clean, pollution-free energy to produce better outputs than other solar panels.

Disadvantages of Dual-Axis Solar Panels

Although seemingly perfect on paper, dual-axis solar panels are synonymous with certain limitations. Some of these limitations include:

• Complex structure and application, making these devices prone to frequent glitches
• Relatively shorter lifespan with lesser reliability than traditional solar panels
• Performance impacted in overcast or cloudy weather

One can resolve most issues by contacting a professional handling dual-axis solar panels.

Where is the Dual-Axis Solar Tracker Market Heading?

Solar trackers are gaining popularity and are increasingly adopted in commercial and residential complexes. The growth of the market is driven by some factors, like:

• Growing demand for effective solar trapping using solar arrays inside panels
• Government subsidiaries and policies that offer tax benefits and other advantages for individuals investing in renewable energy, like solar trackers
• Electricity demand in many parts of the world
