Choosing the Right Solar Panels for Your Business
Choosing to install commercial solar panels and embrace renewable energy to run your business is a big decision. No matter what industry you work in, whether you are a farmer, medical manufacturer or running a warehouse, your business is likely to heavily rely on its energy supply. So, you need to make sure that you choose a system that will meet your specific needs. However, with so many options on the market, how do you choose the right solar panels for your business?
At Excel Energy, we have over 30 years of experience in the solar industry and have gained a wealth of invaluable knowledge during this time. This gives us the expertise to explain some of your options and when they might be suitable.

On-Roof Solar Panels
On-roof solar panels are the most popular type of system and are the panels that spring to mind when you think of solar panels. These can be fitted to all pitched roof styles. From tiled roof, corrugated steel roofing, to trapezoidal roof and fibre cement roof sheets.
As the name suggests, they are fitted directly to the roof of a building. During the installation of these systems, metal hooks are screwed into the rafters of the roof, vertical rails run across the hooks and the solar PV panels are clamped on.
In some cases, tiles may need to be removed for installers to be able to fit hooks.
These solar panels are chosen for a number of reasons. The first is the space they take up. As the entire system is installed on the roof, they don’t intrude on areas of business or land.
Instead, they utilise space that is otherwise not being used. This is particularly advantageous for urban businesses, or those located in densely populated areas.
Additionally, as the panels are higher, there is minimised shading and obstruction from the surrounding area, such as other buildings or trees.
Finally, the higher placement of the system means they are less susceptible to vandalism or theft of parts, meaning they are more secure than alternative options.
In-Roof Solar Panels
In-roof solar panels are similar to on-roof solar panels because they are placed on the roof. However, they differ slightly as they are integrated with the roofing system. This means they are flush with the rest of the roof.
As they are integrated with the roof, these are only an option for new buildings or for those who are replacing their roof and considering installing solar panels as part of this project.
In-roof solar panels offer a cleaner aesthetic because they don’t stand out from the roof but are part of the roof. They offer all of the benefits of on-roof panels. However, their integration with the roof reduces ventilation, reducing their efficiency slightly.
Metal Trapezoidal Roofs
This mounting solution is often used on commercial buildings because it is one of the cheapest and quickest systems to install.
The panels are mounted to the roof in much the same way as an on-roof system is. However, self-tapping screws are used to fasten the rails to the metal roof’s ridges. This minimises the effect of wind by keeping the solar PV panels extremely close to the roof. Furthermore, the system is waterproof because these clamps have a rubber backing.
Flat Membrane Roofs
This solar panel solution is an on-roof solution for buildings with a flat roof.
They are metal triangular structures that tilt the solar panels between 5° to 45° to enhance their performance.
Because these are installed on flat roofs, they are often a cost-effective solution with an easy installation process. This also makes maintaining them slightly easier, as they are easier to access. Finally, like all on-roof options, these utilise space that isn’t currently being used rather than taking up space that could be used for other purposes or space that you don’t have as a business.
Ground Mounted
For businesses with access to a large plot of land or roofs that aren’t suitable for solar panel installation, you should consider ground-mounted PV panels.
These panels use structures that sit on the ground to tilt them towards the sun at a set angle. The most commonly used is a metal frame that is then set in a concrete base or pile driven into the ground to keep it steady.
Often, you will find that you have a larger floor space than roof space, meaning that there is the opportunity to install more panels and produce more energy. This means that a ground-mounted system is likely to have higher performance than a roof system. However, there are drawbacks because the panels are likely to be blacked by shadows and obstructions throughout the day, meaning their timeframe for absorbing sunlight might be reduced.
What To Consider When Choosing Solar Panels
Considering what mounting system you will use is a vital part of the process of installing a solar system. When making this decision, there are a number of factors that need to be considered.
As you will have realised from this article, the first thing you will need to think about is the style of roof your commercial building has. The style of your roof will determine your options for mounting. A flat roof will likely need a system that will tilt the panels up slightly, whereas a pitched roof won’t as the slant of the roof will provide that.
The next consideration that needs to be made is your budget. You will need to have an idea of how much you are willing to spend on this investment as this will also narrow down your options.
Thirdly, you will need to know how much energy your business needs in order to operate. This will determine how many panels will be needed and what other additions you might need in your system, such as energy storage features.
