Benefits of Solar Panels That Follow the Sun

Increased Energy Production

One of the most significant advantages of solar panels that follow the sun is increased energy production due to their tracking system. Unlike traditional fixed solar panels, which can only generate electricity when sunlight hits them directly, these solar panels are designed with tracking technology to follow the sun’s movement throughout the day. This means they can capture more sunlight and produce more energy than passive trackers or stationary panels. These solar farms are becoming increasingly popular due to their ability to maximize energy production.

Solar panels that follow the sun use advanced technology such as sensors and motors to adjust their position based on the movement of the sun. They typically have a single-axis or dual-axis tracking system that allows them to move horizontally and vertically, maximizing their exposure to sunlight. As a result, they can generate up to 25% more electricity than fixed solar panels. These solar tracker panels are ideal for use in farms and land with ample water supply.

This means they can convert a higher percentage of sunlight into usable electricity, making them more efficient and cost-effective, while also conserving water.

Higher efficiency also means that you need fewer solar panels to meet your energy needs. For example, if you currently have fixed solar panels that generate 5 kW of power per hour, installing a tracking system can result in approximately 20% more efficiency. This makes it an ideal solution for water farms, where water is a scarce resource and efficient use of energy is crucial. With the use of tracker technology, water farms can produce 4 kW of electricity with fewer solar panels, reducing their carbon footprint and saving costs.

Lower Costs

While installing a solar tracker system with tracking solar panels may be initially more expensive than fixed ones due to their advanced technology, they offer long-term cost savings by increasing electricity production. Since these panels are more efficient and follow the sun’s movement, they can produce more energy than stationary ones and reduce your overall energy costs. Additionally, the excess energy produced can be used to power water systems, further reducing your utility bills.

  • Lower energy bills: With increased energy production and higher efficiency from solar technology and solar projects such as solar farms and solar installations, comes lower monthly electricity bills.
  • Faster payback period: The additional cost of installing a tracker system for tracking solar panels is offset by their increased energy production and efficiency over time, regardless of whether they are installed on land or water.
  • Higher resale value: Homes equipped with fixed solar panels or solar trackers on their land or water tend to have a higher resale value than those without.

Significant Savings on Energy Bills

The use of solar panels that follow the sun can result in significant savings on energy bills.

This means they help reduce greenhouse gas emissions and combat climate change while providing reliable and sustainable energy. Additionally, solar tracker systems conserve water by optimizing energy production through precise alignment with the sun’s position.

Drawbacks of Solar Panels that Follow the Sun

Additional Costs

One of the main drawbacks of solar panels that follow the sun is their additional cost. While traditional solar panels are stationary, those that follow the sun require specialized equipment and motors to move throughout the day to maximize energy production. This added technology and complexity can significantly increase the overall cost of installing a solar panel system. Ongoing maintenance costs for these systems can also be higher due to their moving parts. Adding water to the tracker is not necessary but may help with cleaning and maintenance.

Limited Space

Another disadvantage of solar panels that follow the sun is their need for more space compared to stationary solar panels. These systems require enough room to accommodate both the solar panel array and its accompanying tracking system. For residential or commercial properties with limited space, this can be a significant drawback as it may not be feasible to install a water tracker system that follows the sun while still meeting energy production needs.

Maintenance Costs

As previously mentioned, maintenance costs for solar panels that follow the sun tend to be higher than those for stationary systems. This is because they have more moving parts, which means there are more components that need regular upkeep and repair. For example, motors used in tracking systems may wear out over time and require replacement, adding additional expenses beyond routine cleaning and maintenance tasks. Additionally, it is important to note that water can damage the tracker’s sensitive electronic components if not properly sealed, leading to costly repairs.

While these disadvantages may seem daunting at first glance, it’s important to remember that they do not necessarily outweigh all of the benefits associated with using solar energy as an alternative power source. In many cases, investing in a high-quality solar panel system – whether it follows the sun or not – can result in significant long-term savings on energy bills while reducing your carbon footprint. Additionally, fixed panels can also be a cost-effective option for those who don’t require the flexibility of a movable system.

When considering whether or not a solar panel system that follows the sun is right for you or your business, it’s essential to weigh both its advantages and disadvantages carefully. If you have ample space available and are willing to invest in a slightly more expensive but potentially more efficient system, then following-the-sun technology may be a good fit. However, if you have limited space or are working with a tight budget, it may be more practical to opt for traditional stationary solar panels instead.

Types of Innovative Solar Tracking Technologies

Solar tracking system technologies that follow the sun’s movement throughout the day can significantly increase the energy output of solar panels. These systems are becoming increasingly popular, particularly in large-scale solar power plants.

Single-Axis Solar Trackers

Single-axis solar trackers are the most common type of solar tracking technology used today. They follow the sun’s movement from east to west using a single axis of rotation. This means that they can adjust the angle of the panels to ensure that they are always facing directly towards the sun.

Single-axis trackers can increase a solar panel’s energy output by up to 25% compared to fixed-tilt systems. They are typically used in utility-scale solar power plants and large commercial installations.

Dual-Axis Solar Trackers

Dual-axis solar trackers can adjust for changes in both elevation and azimuth, meaning that they can track the sun’s movement in two directions. This allows them to capture more sunlight throughout the day than fixed panels and single-axis trackers.

Dual-axis solar tracking systems are more expensive than single-axis trackers but can increase a solar panel’s energy output by up to 40%. They are commonly used in residential and commercial solar systems where space is limited and fixed panels are not feasible. Solar arrays benefit greatly from the use of dual-axis trackers.

Concentrated Solar Power Plants

Concentrated solar power (CSP) plants use mirrors or lenses called heliostats to reflect sunlight onto a central receiver, which then converts it into electricity. Heliostats must be precisely aimed at all times to ensure maximum efficiency.

To achieve this, CSP plants use advanced control systems that track the position of the sun and adjust each heliostat accordingly. This allows them to maintain high levels of efficiency even as the sun moves across the sky during the day. Solar farms utilize solar arrays and solar trackers to achieve similar results, while PES solar technology is also being developed to enhance the efficiency of solar power generation.

Passive Solar Tracking Systems

Passive solar tracking systems use materials that expand or contract with temperature changes to move the panels as needed. For example, some systems use a wax-filled piston that expands as it heats up, causing the panel to move with the sun.

Passive solar trackers are relatively simple and inexpensive but are not as precise as active systems. They are typically used in small-scale residential installations.

Active Solar Tracking Systems

Active solar tracking systems use motors and sensors to adjust the panels’ position as needed. These systems can be programmed to track the sun’s movement throughout the day, ensuring maximum efficiency at all times.

Active solar trackers are more expensive than passive systems but offer much greater precision and accuracy. They are commonly used in large-scale commercial installations and utility-scale solar power plants.

Solar energy is one of the most promising renewable energy sources, and solar panels have become increasingly popular in recent years. However, fixed solar panel installations have limitations. This is where floating solar panels with tracking technology come into play.

Increased Energy Production

Floating solar panels with solar tracking systems can increase energy production by up to 20% compared to fixed solar installations. The reason behind this is that these systems use axis solar tracker technology to follow the sun’s movement and maximize energy output throughout the day.

How Solar Tracking Systems Work

Solar trackers are devices that orient photovoltaic (PV) panels or concentrated solar reflectors toward the sun. They follow the sun’s path from east to west throughout the day, ensuring that the maximum amount of sunlight hits each panel at all times. There are two main types of solar trackers: single-axis and dual-axis.

Single-axis and dual-axis trackers are both types of solar tracking systems used in solar farms. Single-axis trackers move in only one direction, usually east to west, while dual-axis trackers move in both directions and adjust for seasonal changes in the sun’s position. Dual-axis trackers are more efficient than single-axis trackers but also more expensive. PES Solar offers both single-axis and dual-axis solar tracking systems for solar farms.

Increasing Popularity

Floating solar panel systems with tracking technology are becoming increasingly popular in large-scale solar installations and especially in locations where land is scarce or expensive. These “floatovoltaics” can be installed on bodies of water such as reservoirs, ponds, lakes, or even oceans.

One example of a successful floating solar farm is located on a reservoir near London called Queen Elizabeth II Reservoir. The installation consists of 23,000 PV panels mounted on floats that follow the sun’s path using a tracking system.

Another example is Japan’s Yamakura Dam floating photovoltaic power station which has an installed capacity of 13.7 MW making it one of Japan’s largest floating PV projects. This innovative project utilizes solar tracker technology to ensure maximum efficiency and is a prime example of the potential for solar farms on bodies of water.

Advantages of Floating Solar Panels with Tracking Technology

  2. Reduced Land Use: Installing floating solar panels on water bodies can reduce land use and avoid conflicts with other land uses such as agriculture or urban development.
  3. Higher Efficiency: Dual-axis trackers are more efficient than single-axis trackers and can generate more electricity per panel, making them a suitable choice for solar farms.
  4. Reduced Water Evaporation: Floating solar panels can help reduce water evaporation from reservoirs, which is a significant concern in arid regions.
  5. Lower Maintenance Costs: Floating solar panel systems require less maintenance than traditional ground-mounted systems because they are not subject to soil erosion or damage caused by animals or humans.

Two-Sided Solar Panels: A Revolutionary Technology for Increased Efficiency

Solar panels have been a popular way to generate clean energy and reduce carbon emissions. However, traditional solar panels only produce power from one side, limiting their efficiency. Fortunately, two-sided solar panels have emerged as a revolutionary technology that can increase the efficiency of solar energy production.

How Do Two-Sided Solar Panels Work?

Two-sided solar panels use inverters that allow them to produce power from both sides. They are designed to capture sunlight from the front and back of the panel, which increases their overall power output. These panels are also known as bifacial solar panels because they have two faces or sides that absorb sunlight.

Benefits of Installing Two-Sided Solar Panels

Installing two-sided solar panels on rooftops is an excellent way to save space and equipment costs. Since these panels can produce power from both sides, fewer parts are needed for installation compared to traditional one-sided panels. This results in cost savings and reduced installation time.

One significant advantage of two-sided solar panels is their ability to increase power output by up to 35 percent. This means that even in areas with less sun or during times of heat, enough power can be generated using these innovative solar panels.

Another benefit of two-sided solar panels is their flexibility in orientation. Traditional one-sided solar panels need to face south for maximum efficiency since this direction receives the most sunlight throughout the day. However, bifacial solar modules can be installed facing east or west without losing much efficiency since they can still capture sunlight from both sides.

The Future of Two-Sided Solar Panels

As demand for renewable energy continues to grow, so does the demand for more efficient and cost-effective ways of generating it. The price of two-sided solar panels has decreased significantly over recent years due to advancements in technology and increased production.

Research shows that installing bifacial modules may become even more cost-effective in the future. As solar panels become more efficient, their price per watt decreases, making them more affordable for homeowners and businesses alike.
