Why proper mounting is crucial for solar panels

In a solar panel setup, mounting systems hold the PV panels in place. They make sure the panels are at the right angle and direction so they catch as much sunlight as possible.

Basically, the better your PV panels are positioned, the more sunlight they’re going to capture. In turn, this means more energy for your home or business.

Without a proper mounting system in place, the panels won’t be positioned correctly. Inevitably, the panels wouldn’t be able to perform at their best and it would lead to less energy production.

Talk about a solar panel mounting failure: no one wants to deal with a 300 kW burnt-out isolator on the roof, but with improper mounting, you could face just that (Image by h080 from Flickr, licensed under CC BY-SA 4.0 ).

Improper mounting can lead to many problems:

  • If the panels aren’t securely attached they could move or shift in strong winds. This reduces their ability to catch rays of sunlight and could potentially damage the panels as well.
  • Over time, poor solar panel mounting jobs could lead to the panels coming loose and causing serious damage, not just to the panels, but to your property. The end result could be repairs that cost a fortune and reduced energy output, defeating the purpose of investing in solar in the first place.

Long-term benefits

There are many benefits to investing in the right solar panel mounting system from the start. In the long run, it’ll mean less maintenance.

When it’s mounted correctly, the solar PV system is less likely to need frequent adjustments or repairs, which saves you both time and money.

Additionally, a well-secured panel system can help prevent overheating by allowing proper airflow around the panels, which is vital for maintaining efficiency.

No matter what, the right solar panel mounting solution is key to ensuring that your solar panels operate effectively, last longer, and provide maximum return on your investment.

Solar panel mounting options

Just like there are different types of solar panels to learn about before installing, when considering solar panel mounting options, there are also many available. What you choose will depend on what you need and where you want to install your solar panels.

For instance, roof mounts are quite common for homes with plenty of roof space while ground mounts are perfect for properties with open land but limited space on the rooftop. There are even vehicle mounts for those who wish to power caravans or boats.

DID YOU KNOW… Did you know that roof solar panels ensure higher energy yields and long-term savings compared to ground-mounted systems? Roofs provide the best angles and exposure for solar panels!

Each solar mount provides its own benefits and is suited for these situations, which makes it important to choose the best one to fit your needs and the installation environment you’re working with.

Factors to consider

When deciding on your solar mounting option, several factors will come into play. Things like the type of roof you have.

Is it flat, pitched, or covered in tiles? For example, for slate roofs, specific considerations include the use of solar limpets for fixing and sealing techniques unique to this type of roofing.

The weight and size of solar panels also matter. For instance, heavier panels could require stronger mounts or additional support. Weather conditions, such as high winds or snowfall that occur in your area more often could affect which mounts are best.

Additionally, other factors to consider when choosing these mounting options have to do with the ease of installation and any potential need for maintenance. In some cases, the mounting system may be easier to install, but require more frequent maintenance.

Ensuring longevity

To make sure that your solar panels last a long time, you need to choose a solar panel mounting system that fits the PV panels and the specific surface they’ll be installed on.

This means checking that the mounts can hold the weight and size of your panels and are designed for your specific roof or ground conditions.

The right mounting system is going to keep your panels in place and help withstand many weather conditions, and aims to make your solar system more durable.

Additionally, a compatible setup is a way to ensure that everything functions properly from start to finish, working smoothly and providing reliable energy for many years to come.

Roof mounting solutions

Pitched roofs

For pitched roofs, there are several solar panel mounting system options that work well, such as hooks and rails. These systems attach directly to the roof rafters. They provide a secure, stable base for panels.

This solar panel mounting system method is a popular option because it allows for good ventilation underneath the panels and prevents overheating for optimal performance.

The angle of a pitched roof often fits perfectly with the angle required for the panels to collect the maximum amount of sunlight, especially if the roof is south facing.

However, it’s important to think about the exact angle and orientation if you wish to get the best results.

Let’s look at the benefits of pitched roof mounting systems:

  • It positions the panels at the best angle to catch the sun’s rays throughout the day, generating more electricity.
  • The elevation allows for better airflow, keeping panels cool while maintaining efficiency.
  • It’s less invasive, generally preserving the roof’s structure.
  • It provides strong support and durability for the PV panels.

Flat roofs

Flat roofs require a different approach when it comes to mounting solar panels. This is because they don’t have that natural slope to capture the sun’s rays. Here, specialised panel mounting systems are used.

Standing seam roofs are also an excellent choice for mounting solar panels. Clamps can be used to secure solar PV systems directly to the standing seams, providing a robust and leak-free installation.

Ballasted systems, which use weights to secure the panels, are popular because they don’t need to penetrate the roof, reducing the risk of leaks or damage.

Another option for a flat roof is the East/West solar panel mounting systems. This mounting system arranges the panels in a way that reduces wind resistance and ballast requirements.

Here’s what to think about with flat roof mounting systems:

  • Check that the roof can support the extra weight.
  • Evaluate the roof’s structure to see that it can handle the mounting system.
  • With flat roofs, adjustments may be needed to tilt PV panels correctly for sunlight exposure.
  • Select a roof mount that gives you plenty of space and provides a secure installation.

Ground mounting solutions

With ground-mounted solar panel systems, you get several advantages, especially if you have a property where roof space is limited or not suitable for solar installation.

Many customers are now opting to build their own roof on the ground, creating personalised structures such as log stores and wooden frameworks to customise their outdoor spaces for solar panel installation.

This type of system allows you to place the PV panels in an open area where you can optimise their positioning for maximum exposure to the sun’s rays throughout the day.

Ground mounts can be easier to install and maintain as they are more accessible than roof-mounted panels. This makes them a great option for larger solar installations or for anyone who wishes to expand their system in the future.

There are a few different types of ground mounting systems to choose from:

  • Metal frames: These are strong and long-lasting, allowing you to adjust the angle to get the most sunlight.
  • Mono-pole metal frames: Ideal for uneven ground since they don’t need as much preparation, making installation easier.
  • Console bins: Offer flexibility and can be adjusted to suit various ground conditions, making them versatile for different sites.

Here what to consider with ground mount solar panel systems:

  • Check the ground’s conditions to see if any extra support is needed
  • Be aware of any nearby objects that could possibly cast shadows on the panels
  • Think about security concerns, like fencing, in order to protect ground-mounted PV panels, which could be easily accessible.

Roof vs Ground solar panel mounting

Prioritising your roof for solar panel installation is often the most effective way to harness solar energy. Roofs typically offer the best angles and exposure for solar panels, leading to greater energy yields and long-term benefits compared to ground or vehicle-mounted systems.

At Soly, we currently specialise in transforming rooftops into highly efficient solar energy systems. While we don’t usually offer ground mounts or solar solutions for tiles, vans, or cars, our expertise is dedicated to optimising roof installations to maximise energy production and efficiency.

By focusing on roof installations, we ensure that you get the most out of your solar investment.

Materials used in solar panel mounting

When it comes to solar panel mounting systems, the materials can make a world of a difference in terms of durability, cost, and suitability.

Stainless steel is a go-to choice that’s well-known for its exceptional strength and resistance to rust. This is ideal for coastal areas where salt can cause corrosion.

Aluminium is another common material. It’s known for being lightweight and durable. It can be beneficial for reducing the overall weight on a roof.

Galvanised steel, coated with a layer of zinc, provides a balance between cost and durability. It offers decent rust resistance at a lower cost compared to stainless steel.

Why material selection is important in the South African climate

  • South Africa as a whole has varied weather of various intensities. This includes rain, strong winds, frost, high summer temperatures and in very rare cases snow. It’s important to choose materials that can withstand conditions like these.
  • Selecting the right materials will help your solar panels last longer and stay efficient by avoiding weather-related wear and tear.

Mounting system accessories

Mounting system accessories are designed to enhance the performance and durability of the solar panel system. These accessories include clamps, brackets, and tracking systems.
