Solar electric power can be made available continuously for consistent on-off grid applications. It is environmentally friendly as well. Solar mounting panels are necessary to increase the efficiency and probability of the solar panels to generate power.
Here’s a guide that will help you know everything essential about the PV panel mounting brackets or solar panel brackets- necessities, benefits, types, material components, and probable solar systems, essential few things to consider while choosing the right type, probable steps to install them, other practical things that you must know while installing solar energy system.
PV Panel Mounting Brackets
PV panel mounting brackets secure solar panels, ensuring stability and optimal performance. Brackets are fixed in a way that the solar panels are exposed to an outer sunlight surface and the brackets can be set on a roof, ground, or wall as per the situation. Most importantly, these brackets are not just an accessory to the solar panels but the essential component to get the desired energy goals.
As every machine, building, and equipment requires some kind of structure to hold itself to operate or sustain, the solar power mounting systems and their cells and panels use PV panel mounting brackets as their base to protect them from all the harsh conditions and difficult weather throughout the year. These solar panel’s support structure designs enable solar panels to produce the maximum amount of energy and occupy the least amount of space. Generally speaking, the best solar panel brackets are sturdy, durable, and require less time to install.
Why PV Panel Mounting Brackets Are Essential for Solar Installations
Solar PV systems work in a variety of types of areas. They work on urban solar rooftops and on the remote off-grid locales of the country. Whether you choose to use a Solar PV system on a residential rooftop, or in the middle of nowhere, keeping them producing energy is fundamental. That is why PV mounting brackets are supposed to orient the panels at the right tilt, and they can work properly with optimal results.
Orientation is important, as the most energy output can occur when your panel is 90 degrees perpendicular to the sun’s rays. Wind loads and sometimes, even thermal expansion can produce severe stress on the panels, which can cause them to convert less energy. This is where mounting brackets come in, to protect your panels from these forces, and allow them to survive longer and keep producing energy up to its system potential.
Types of PV Panel Mounting Brackets
PV panel mounting brackets come in several types, each of them are designed for a specific application or installation environment. So selecting the right type is very essential and important to make sure that it has compatibility with respect to site or location, solar panel design, and energy goals. Below are the main categories;
Roof-Mounted Brackets
Roof-mounted brackets are a type of solar system installation that are widely used for residential or commercial requirements. This system is placed directly on the roof, and there are different types of them. They are mainly categorized into two, they are pitched and flat roof solar panel brackets.
In the case of the normal roof, i.e. pitched roof, the solar fixing brackets are cut to the angles of the roof. In many cases, installing solar panel systems on angled roofs lets the producers manage the tilt easily. Also, these fitting clamps do not penetrate the surface which helps to keep the roof of the building as it is.
Flat roof brackets for solar panels station the solar panels similar to the pitched roof with the help of the ballast system. These panels are tilted to an adjustable degree the supplier needs, and it can concentrate on absorbing the solar power all through the day.
Pitched roof solar systems suit best for urban conditions since the solar panels are tilted at the right angle, whereas flat roof solar panels are arranged to capture the solar power in the most optimal direction.
Ground-Mounted Brackets
Solar panels can be ground-mounted when roofs are unsuitable or require larger systems. Solar panels brackets hold the solar panels to the ground and are usually fixed frames. In some cases, the brackets can also be tracking systems that are used to track the sun’s path.
A ground-mounted system is more adaptable in this sense to give an optimal tilt and orientation. The solar panel system depth might require more space usually depending on technology. Ground-mounted solar panels offer higher energy yield efficiency. These panels are also more accessible for cleaning, maintenance, and inspection of the system. Ground-mounted solar panels may have higher installation costs due to the need for excavation and anchoring.
Wall-Mounted Brackets
Wall mounting solutions are less widespread than the other two, but they can be an innovative solution for buildings when the roof space or ground space may not be sufficient. Brackets are used for mounting the panels to the vertical wall with a slight tilt and to gain more sunlight. It is perfect for city solar and can get more convenient.
Tracking Systems
Tracking systems are one of the latest and high-end technologies for solar mounting. Motorized brackets are used by these systems to move the solar panel’s position throughout the day; these panels should be perpendicular or just perpendicular to the sun’s rays. To move the panel horizontally or vertically, single-axis or dual-axis trackers are used. Tracking systems are costlier and need regular maintenance, but they produce more energy, particularly in high solar radiation areas.
Materials and Durability
Materials play a big part in how well PV panel mounting brackets work and last. One of the most popular metals bought for this purpose is aluminum. It is a lightweight metal with corrosion resistance, making it ideal for roof-top installations. Stainless steel panels, on the other hand, have increased strength and are also corrosion-resistant, perfect for the ground-mounted system located in harsh environments.
Moreover, apart from these two aluminum and steel, galvanized steel is the most economical choice of the two. It lasts long and is wear-resistant as well. Both aluminum and steel panels can be treated with various methods to prevent damage; for example, anodized aluminum panels and hot-dip galvanized steel.
Key Considerations for Choosing PV Panel Mounting Brackets
Choosing the right mounting brackets for PV panels is a must. The foundation must be perfect to ensure that the solar energy system lasts long, is durable and productive. Moreover, the brackets place the solar system panels against all environmental forces and help in their alignment for maximized productivity. Here are some of the main factors given for choosing the best.
Compatibility with Solar Panels: You have to ensure that the type and the size of your solar panels compatible with the mounting bracket. Every solar panel model has different dimensions and weight distribution. That’s why not every kind of frame suits every solar panel. If the solar panel’s mounting is wrong, it might affect the frame, which can cause the entire system to shut down.
Installation Site Characteristics: There is an important primary factor that needs to be taken into account before selecting the kind of mounting brackets. The area of installation is a first consideration. For example, if you are using solar panels on top of a roof, it is crucial to consider the angle and pitch of the roof, the type of material from which the roof is made, and the roof’s weight capacity. A place with a flat roof may use tilted and flexible brackets to spread out its solar panels to make it more exposed.
Wind and Snow Load Ratings: Determine which type of Solar panel Support Structure is best for your application by assessing the wind speed and the snow load of your area. If the area is prone to natural events like heavy snowfall, rainfall, hurricanes, etc, it is risky to use simple mounting brackets. In that case, the brackets that are sound and steady should be the choice for this environment.
Adjustability and Tilt Angles: The important point to recognize here is that a considerable advantage that comes with some of the PV mounting systems is the adjustable tilt angles. The effectiveness of the solar panels in capturing sunlight during the year is dependent on the tilt angle. The brackets adaptable to the inclination angle are of utmost importance in areas where the intensity of sunlights are different. Manual or automatic modification to the angle is a significant plus to optimize energy.
Ease of Installation: One must consider the installation complexity as it can affect the time and costs needed for solar system setup. Sometimes these brackets come with a straightforward assembly design and easy installation protocols. The easy installation reduces overall cost by reducing labor costs. You can also choose modular systems with pre-drilled holes and easy-to-understand DIY instructions if you want your project to be completed quickly.
Cost-Effectiveness: Deciding to buy the cheapest brackets can be tempting, but you should consider the quality and longevity of the products. High-quality mounting solutions may be expensive in the beginning, but you may avoid the long-term maintenance bills and secure a longer lifespan for your solar system.
Aesthetic and Structural Integration: The solar brackets should give an aesthetic appeal for residential and commercial uses. The commercial building should have a low-profile appearance if it uses rooftop solar panels to keep its building aesthetic. Regardless of the application, the brackets shouldn’t compromise the building’s safety and its own functionality.
Installation Process for PV Panel Mounting Brackets
The process of installation of photovoltaic mounting brackets includes several vital steps that are critical for stability, efficiency, and safety. The steps are :
- A successful installation should always perform an on-site assessment to determine the type and layout of stretch brackets that are most suitable for the project.
- Align and space brackets and make assembly of mounting brackets is the next process after the brackets are secured to the surface of the location.
- The use of clamps, rails, or ballast systemsfor panels to be placed in the brackets is an important step while making sure that very little impact on the rooftop structure. For the ground-mounted PV system, the use of anchor systems in order to have a solid base is necessary by applying either concrete foundations or driven piles.
- After attaching panels to the bracket properly, the electrical connections will be put in place to complete the system. Proper installation of PV mounting brackets will increase energy production and decrease damage or malfunction.
How to Choose?
There are numorous factors to consider before picking the suitable PV panel mounting brackets. The factors include the Installation cost, space requirement, maintenance, and surface of installation of the project. Roof-mounted systems are cost-effective and take up less space whereas the ground-mounted systems provide the flexibility of placement and easy access to it. Tracking systems, although more costly, offer an increase in energy output in regions with high solar potential.
