Solar power is a leading source of clean, sustainable energy as the world moves towards renewable sources. Choosing the right mounting method for solar energy systems is crucial. Solar mounting systems are essential for attaching solar panels to roofs, the ground, or water.
This article will explain the importance and functionality of solar mounting systems.
What are Solar Mounting Systems?
Solar mounting systems securely hold solar panels in place. They can be set up on rooftops, ground, or water to get the most sun. These systems keep solar panels stable and at the best angle for generating energy. Each type of solar mounting system is used based on the location and power needs.
The Importance of a Reliable Solar Mounting System
The main job of a solar mounting system is to provide a stable foundation for solar panels. If the mounting system is not strong enough, the panels could fall, possibly causing damage and injury. How well the solar panels work largely depends on their mounting. The ability of the panels to turn sunlight into energy is affected by their angle and orientation.
The mounting system ensures the panels are positioned correctly for the best energy production.
What are the Types of Solar Mounting Systems?
Several types of solar mounting systems match different installation needs. The most common solar mounting system designs include:
Roof Mount
Many people recognize homes with solar panels on the roof, such as those with flat-roof solar installations. Rooftop solar installations suit different roof types, including flat and shingled roofs. You can choose between solar shingles and solar panels depending on your needs and budget.
Installers consider factors like roof type and slope, local weather conditions, latitude, and nearby buildings or trees that might cause shade. The choice of solar roofing depends on your roof’s age, the available equipment, the efficiency of the system, and personal preferences.
Pros & Cons:
Rooftop solar is often the cheapest option for homes and is very popular. You can’t place panels anywhere, but you can put them on structures like sheds or carports if not in your home.
However, rooftop systems can damage your roof, potentially causing leaks. They also might be less efficient due to poor airflow under the panels. Solar systems are durable, but your roof might need repairs before the solar panels do. Safety-wise, rooftop panels can make maintenance more dangerous and expensive than ground-mounted options.
Ground Mount
Ground-mounted solar panels are installed on land or in open fields with posts. This method requires more equipment than roof installations but is more efficient. Ground systems are simpler to adjust for optimal sun exposure and easier to set up than roof-mounted ones. Some advanced systems can also automatically adjust to catch more sunlight.
Pros & Cons:
Ground-mounted solar panels are easy to clean without needing to climb or hire help. They’re suitable for complex roofs, older roofs needing replacement, or to avoid visual issues. If you have unused, sloping land, it’s an excellent panel spot, ideally facing south, though not always possible with roof setups.
Ground mounts let snow slide off in snowy areas, improving efficiency with reflected sunlight. But, they require enough space and might use up yard area or not meet local regulations. Ground conditions like sandy or unstable soil could increase installation costs due to specific excavation, cement, trenching, and conduit needs.
If your land is suitable, ground-mounted panels can avoid heavy renovations and keep your home’s look.
Flat Roof Mount
Flat roof mounts are great for nearly flat roofs, typically having a slope of about 1-10 degrees. This method allows for efficient use of space on roofs with minimal incline, optimizing sun exposure for energy generation. It’s a practical solution for buildings that cannot accommodate traditional sloped solar installations.
Pros & Cons:
A flat roof allows for a more adaptable setup, enabling panels to face the best direction for sun exposure, which can increase energy production.
The main issue is ensuring the roof drains well to prevent water from pooling and damaging the panels. Depending on how they’re built, flat roofs might need extra support for the panel’s weight.
Tracker Mount
These systems have motorized trackers that track the sun from sunrise to sunset. The trackers keep the panels at the best angle to the sun, increasing energy efficiency.
Pros & Cons:
Solar tracker mounts maximize generation during peak hours and optimize the potential of limited space by avoiding shading, which raises efficiency. However, they come with a high installation cost, have a complex installation process, and are difficult to maintain.
Carport Mount
Carport structures resemble ground-mounted solar structures but are elevated to allow parking underneath. They convert underused spaces into areas that generate clean energy and can easily incorporate EV charging stations. Suitable for residential and commercial use, solar carports are sleek and improve the appearance of the space.
Pros & Cons:
Solar carport mounts are easy to maintain and effectively use underused spaces for energy generation. They serve the dual purpose of generating energy and providing shade. However, a major drawback is that they require shadow-free land space for setup.
Balcony Mount
Balcony-mounted solar systems are ideal for living in apartments or houses with little roof space. They attach to balcony railings or walls to use sunlight in smaller spaces. These systems are small, easy to set up, and can be adjusted to get the most sun, increasing energy production in limited areas.
They offer a way for people to lower their carbon footprint when they don’t have access to a traditional roof or ground space for solar panels. The installation process is simple, and these systems usually come as kits for DIY assembly.
Pros & Cons:
Balcony-mount solar systems make solar energy possible in places without access to roofs or ground. Perfect for cities and apartments, they offer a renewable energy option for crowded places. They’re easy to install without big changes and suitable for renters and homeowners.
However, they produce less energy due to their small size. Despite this, they bring solar power to more people, helping with energy sustainability. Their maintenance is simple, promising long-lasting use with little work.
Floating Mount
A floating solar mounting system allows solar panels to be installed on water surfaces such as lakes, ponds, reservoirs, or seas. The panels sit on floating platforms that are anchored to the water or attached to the bottom.
Pros & Cons:
Floating solar panels offer several benefits over traditional ground-mounted systems. They make use of water bodies, freeing up land for different purposes. The water naturally cools the panels, extending their life and improving efficiency. The reflection off the water surface can also increase the energy output of the solar panels.
Pole Mount
Pole mounting is similar to ground mounting but involves attaching panels to poles at an angle. These stands are strong and can hold over ten panels. You can choose to mount on the side or top of the pole or use advanced tracking for better efficiency.
Pros & Cons:
This type comes with similar perks to ground mount: if your roof is not ideal for solar panels, you can still use the technology. Your pole mount will take up less yard space than a ground mount. You get height exposure without installing the modules on the roof. The panels can also be set up to track the sun throughout the day to maximize optimal sunlight absorption.
However, because of the moving parts, this is the most expensive solution and requires regular maintenance for single—or dual-tracking solutions.
Key Components of a Solar Panel Mounting System
A solar mounting structure is made up of components that securely connect to the panel. These components are:
Roof attachments
Roof attachments use fasteners drilled into the roof to hold the racking system securely. Flashing—a plastic or metal shield—is placed under the shingles to prevent water from entering the holes made by drilling. The type of roof attachment needed varies with the roof type. Roof attachments are installed by drilling into the roof and using flashing for water protection.
Module clamps
The module clamps connect the roof attachments, drilled in, to the mounting rails. Each angle and corner of the solar panel has a specific type of module clamp. These clamps are available in different sizes and shapes to ensure the roof attachments are securely fastened from every angle.
Mounting rails
First, drill into the roof and connect the roof attachments to the mounting rails using module clamps to support the solar panels. While railless systems exist, rails are popular because they fit most roof angles, and many installers are familiar with them. Mounting rails are attached to the roof, and the solar panels are adjusted to match roof angles.
