Solar Mounting Structures
Solar installations have been rapidly increasing around the world. India has generated a significant amount of growth, and with a target of 100GW by 2022 (40GW rooftop solar energy capacity by 2022), India is on the verge of becoming the world’s largest solar nation, with zero emissions until 2070. Continuous price reductions in solar systems in comparison to higher grid rates are driving up global demand for solar solutions, resulting in significant growth.
Solar is undeniably the way of the future and a leading sustainable energy source. Solar panels perform best when exposed to direct sunlight for the longest period and are positioned at a specific tilt angle with the face facing south. Solar Panel Mounting Structures come into play in this situation. The mounting system is one of the most innovative aspects of solar panel installation.
Solar Mounting Structures are critical to the efficient operation of a solar power system in both utility and rooftop applications. While the most balance of system (BOS) components, including inverters, DC cables, junction boxes, transformers, and so on, are easily available from equipment manufacturers, an EPC contractor’s workmanship is mostly evident through solar mounting structures and wiring management.
These frameworks allow panels to rest comfortably, avoid damage, and, most significantly, place them at a perfect tilt angle to maximize solar energy harvesting. Rooftop solar mounting structures, ground solar mounting structures, carports, and sun tracker solutions have all experienced significant advancements in terms of weight, material, versatility, and ease of installation. Many technological advancements have resulted in lower costs, faster and better installation, increased durability and increased productivity.
Solar projects in India have recently been installed using a variety of solar mounting technologies and designs, including galvanized iron and aluminum structures. Some projects have combined steel and aluminum structures, with vertical legs constructed of hot-dipped galvanized steel and the remainder of the members built of extruded aluminum. The following components are typically found in a module mount structure.
Material plays a significant role in the total solution because any solar system is designed to last 20 to 25 years. The topography and environment of the installation area determine the material’s strength. As a result, there is an increasing demand in the industry for very durable, rust-free, corrosion-resistant materials. This has resulted in the development of revolutionary products such as rust-resistant steel, which has become quite popular in the solar panel market due to its low cost and increased endurance.
Steel comes in a variety of weights, strength grades, and coatings, all of which have various pricing. For the best return on investment, look at the warranty provided by the firm while choosing the material. Mounting systems are a key component of solar arrays—they secure solar panels to the roof or the ground—and are likely the most competitive solar product market. To assist new installers, we go over the fundamental categories of roof-mounted solar systems in this article.
Types of Solar Mounting Structures
In terms of the overall production, efficiency, and lifetime of solar panels, the precise and proper selection of solar mounting structures for solar system projects is critical. Because it is such a large expenditure, the choice of mounting systems should not be taken lightly. Solar modules must be fixed, installed, and clamped on a very stable and durable structure, which will protect the array from wind, hail, rain, snow, and even moderate earthquakes. They can be put on the ground, roofs, or poles. There are five primary types of solar mounting structures, four of which are fixed angle and one of which is variable angle:
- Roof Mounted Racks
- Ground Mounted Racks
- Top-of-pole Mounted Racks & Side-of-pole Mounted Racks
- Tracking System Mounted Racks
Roof Mounted Racks reduce wire run distances between the solar array and the battery bank or inverter, but they necessitate roof penetrations and risk producing roof leaks, thus the roof must be tightly sealed. Another downside of roof-mounted structures is that if the roof orientation and angle are not appropriate, your system will waste a lot of potential energy. You must guarantee that there is no shade from trees or other structures in the optimum free circulation path of your solar panels if you are utilizing a roof-mounted system. Seismic behavior analysis, boundary layer wind tunnel testing, and UL 2703 certification for grounding and bonding are among the design engineering issues. When your home or building has enough room for all of the solar panels you need, roof mounts are ideal. They can also be fixed or adjustable, and they can be used in conjunction with a solar tracker.
Ground mounts are typically used to mount solar panels to the ground on your property. This is a potential solution if your roof lacks the room for a roof mount or is excessively shadowed by trees or is located in the sun’s path. They are frequently adjustable so that they can tilt up or down for maximum sunlight absorption at different times of the day. The disadvantage is that ground-mounted constructions are vulnerable to vandalism, dirt, leaves, and snow accumulation at the bottom of the array. As a result, ground-mounted racks should only be used in secure areas that are clean and stable (with little snow or dirt on the ground).
Pole Mounts are used to securing solar panels to poles, as the name implies. “Top-of-pole” and “side-of-pole” are the two main types of pole mounts. The former permits the solar panel to be mounted on top of a pole, several feet above ground level. The latter secure solar panels to poles’ sides. Top-of-pole Fixed Racks are constructions in which the solar module is mounted on top of mounting poles that are fastened to the ground and tightened with concrete. The advantage is that it is less vulnerable to vandalism and dirt, leaves, and snow accumulation, but it is difficult to clean. Side-of-pole Solar systems with a small number of modules are often installed on mounted racks.
Tracking System Mounted Racks can be utilized for solar tracking systems as well as solar water pumping systems, allowing for the most amount of solar radiation to be exploited for energy generation. They are very beneficial in hot regions. One-axis and two-axis mounted structures are available for tracking systems. One-axis trackers measure the sun’s movement from east to west, whereas two-axis trackers track the sun’s daily and seasonal path and are commonly employed with PV concentrator systems. Solar trackers are an automatic device that allows your panels to follow the direction of the sun throughout the day for the best solar exposure and collecting. While solar trackers improve efficiency and eliminate manual panel maintenance, they are not widely employed due to the high total cost and the addition of another moving item that could break down and cause difficulties for the array.
Different Types of Roof Mounts
Flush Mounts are a low-cost, straightforward alternative that can be used with most roof-mounted solar panels. They are usually not adjustable and, as the name implies, are intended to be flush with the roof surface. Metal clamps keep the solar panels in place, leaving roughly 2-4 inches of space between the roof and the bottom of the panel. This provides for lots of airflow down the panel’s underside, keeping it cool and efficient.
When a panel overheats, its efficiency and lifespan suffer. These mounts are ideal for households, but not so much for businesses. Roof mounts are designed to safeguard both your roof and the solar panel. The flush mount decreases the solar panels’ wind load. Flush mounts are perfect for lowering the dead load on your roof; they operate with any type of system, are suitable for high wind zones, allow for panel slope and orientation flexibility, and interfere minimally with roof drains.
They are not without flaws, however. Depending on the type of roof you have, installing a flush mount may necessitate a roof penetration (which isn’t usually necessary), increasing the danger of roof leaks.
Ballasted Mounts are similar to flush mounts, except they use weights to keep the solar panels on your roof in place. This design can save labor time and money, but it also adds the problem of moving the weights onto the roof, which can be fairly difficult with larger systems. Ballasted mounts eliminate roof penetrations, are quicker and less expensive to install, and allow for a panel tilt of up to 20 degrees for best sun exposure. This mount, on the other hand, adds to the weight on your roof, has a lower power density, and is less ideal for high-wind environments. Certain site characteristics, such as roof slope and building height, limit them.
Hybrid Mounts are a blend of flush mounting and ballasted mounts, as you might expect. Some structural pieces from both mounts are used to accommodate roofs that can’t support either. Hybrid mounts need little roof penetration, can be installed quickly (depending on the model), and allow for specific design optimization based on load-bearing and wind. These mounts are often more expensive and take up more space on your roof, reducing the amount of space available for your system.
Roof-ground Mounts resemble standard ground mounts in appearance, but they may “sit” on your roof. This may be preferable to a flush mount depending on the type of roof you have. Roof-ground mounts can be adjusted or set to provide maximum sun exposure throughout the year.
